The heat exchanger plays a vital role in the air conditioner, is a key component in a refrigerant circulation system of the air conditioner, and has direct influence on the performance and efficiency of the air conditioner. The refrigerant circulation system mainly comprises four basic components of a compressor, an outdoor heat exchanger, a throttling device and an indoor heat exchanger, and forms a closed circulation loop.

The compressor is a heart of a refrigerant circulating system, and has the main task of sucking low-temperature and low-pressure refrigerant gas from the indoor heat exchanger and changing the refrigerant gas into high-temperature and high-pressure gas after compression. After the high-temperature and high-pressure refrigerant gas enters the outdoor heat exchanger, heat is released to the external environment through heat exchange with external air or cooling water, and meanwhile, the high-temperature and high-pressure refrigerant gas cools and forms high-pressure liquid. When the high-pressure liquid passes through the throttling device, partial liquid can be evaporated into gas through throttling and depressurization, and the surrounding heat is absorbed, so that the temperature and pressure of the refrigerant are further reduced. And after the low-pressure refrigerant liquid enters the indoor heat exchanger, the low-pressure refrigerant liquid exchanges heat with indoor hot air. The refrigerant absorbs the heat of the hot air, gradually changes from a liquid state to a gaseous state, and simultaneously reduces the temperature of the indoor heat exchanger, thereby achieving the aim of indoor cooling.

The refrigerant is compressed into high temperature and high pressure gas by the compressor, cooled into high pressure liquid by the outdoor heat exchanger, depressurized and partially evaporated by the throttling device, evaporated into gas by the indoor heat exchanger by absorbing indoor heat, and enters the compressor again to complete a refrigeration cycle. The flow direction of the refrigerant is opposite during heating. Therefore, the air conditioner can effectively adjust the indoor temperature through continuous circulation of the refrigerant, and a comfortable indoor environment is provided for people.

As shown in connection with fig. 1, the disclosed embodiment provides a first heat exchanger comprising a main heat exchange tube 100 and an auxiliary heat exchange tube 110. The first end of the main heat exchange tube 100 is a first inlet 101, the second end of the main heat exchange tube is a first outlet 102, the tube diameter of the main heat exchange tube is a first tube diameter, the first end of the auxiliary heat exchange tube 110 is a second inlet 111, the second end of the auxiliary heat exchange tube 110 is a second outlet 112, the tube diameter of the auxiliary heat exchange tube 110 is a second tube diameter, and the second tube diameter is smaller than the first tube diameter, wherein the first outlet 102 is communicated with the second inlet 111, the auxiliary heat exchange tube 110 is wound on the main heat exchange tube 100, a refrigerant enters the heat exchanger from the first inlet 101 and flows out from the second outlet 112, and the auxiliary heat exchange tube 110 can exchange heat with the main heat exchange tube 100, so that the heat exchange efficiency is improved.

In this embodiment, the auxiliary heat exchange tube 110 is provided to replace the conventional fins, so that the overall heat exchange area of the heat exchanger is effectively increased. In addition, the pipe diameter of the auxiliary heat exchange pipe 110 is smaller than that of the main heat exchange pipe 100, so that the auxiliary heat exchange pipe 110 can be mounted on the main heat exchange pipe 100 in a compact winding manner. In this way, the auxiliary heat exchange tube 110 occupies only a small installation space, and the longer auxiliary heat exchange tube 110 can be arranged in a limited installation space, so that the heat exchange efficiency is improved, and the whole heat exchanger is prevented from being large in size. The refrigerant enters the heat exchanger through the first inlet 101 and flows out through the second outlet 112, that is, the refrigerant flows from the main heat exchange tube 100 to the auxiliary heat exchange tube 110. In this way, along with the circulation of the refrigerant, the temperature of the refrigerant in the auxiliary heat exchange tube 110 is smaller than that of the refrigerant in the main heat exchange tube 100, so that the auxiliary heat exchange tube 110 can exchange heat with the main heat exchange tube 100, thereby further improving the heat exchange efficiency.

Optionally, the main heat exchange tube 100 comprises a plurality of main tube sections and hairpin tubes 120. The two ends of the hairpin tube 120 are respectively used for communicating with adjacent main tube sections.

In this embodiment, the hairpin tube 120 is configured in a U-shape. The strength and stability of the connection between the main pipe sections is enhanced by the hairpin pipes 120. Two ends of the hairpin tube 120 are respectively communicated with adjacent main tube sections, and a continuous fluid channel is formed, so that the refrigerant can smoothly flow between the main tube sections. And, by adjusting the number and layout of the main pipe sections and the hairpin pipes 120, the overall structure of the heat exchanger can be conveniently changed to adapt to different working environments and heat exchange requirements. The flexibility enables the heat exchanger to be better suitable for various complex heat exchange scenes, and the application range of the heat exchanger is improved.

Optionally, the auxiliary heat exchange tube 110 is wound around at least one main tube segment. In this way, the auxiliary heat exchange pipe 110 may be selectively wound or not wound according to the heat exchange coefficients of the different main pipe sections, thereby contributing to cost saving.

Illustratively, due to the different locations of the plurality of main tube segments, or due to frost or fouling on the surface of some of the main tube segments, a portion of the main tube segments, referred to as the first type tube segment 210, have a relatively low coefficient of heat transfer. In this case, the auxiliary heat exchange pipe 110 (not shown) may be wound only on the first-type pipe section 210, which can improve the heat exchange effect of the first-type pipe section 210 and save costs.

Still another example, all the main pipe sections are wound with the auxiliary heat exchange pipe 110. Thus, the heat exchange area of the whole heat exchanger can be increased to a large extent.

Alternatively, the auxiliary heat exchange tube 110 is wound in a spiral form in the axial direction of the main tube section.

In the present embodiment, the spiral form of winding makes the contact between the auxiliary heat exchange tube 110 and the main tube segment more tight. And compared with the traditional parallel arrangement mode, the spiral winding can more effectively utilize the space, so that the heat exchange area in unit volume is obviously improved, and the heat exchange efficiency can be effectively improved. And, the auxiliary heat exchange tube 110 is tightly wound on the main tube section in a spiral form, and both form a relatively fixed structure. Therefore, deformation or damage of the heat exchanger caused by vibration or external impact in the operation process can be reduced, and the service life of the heat exchanger is prolonged.

Alternatively, the winding intervals of the auxiliary heat exchange tubes 110 on the same main tube section are the same.

In this embodiment, since the winding intervals of the auxiliary heat exchange tubes 110 are the same, the refrigerant can exchange heat with the auxiliary heat exchange tubes 110 uniformly while flowing through the main tube section. In addition, the auxiliary heat exchange tubes 110 are uniformly distributed on the main tube section, so that damage risk caused by local stress concentration can be reduced. Meanwhile, the uniform winding interval is also beneficial to maintaining the structural balance of the heat exchanger, and vibration or instability is prevented from occurring during operation.

Alternatively, the winding intervals of the auxiliary heat exchange tubes 110 on the different main tube sections are the same.

In this embodiment, since the winding intervals of the auxiliary heat exchange tubes 110 are the same on different main tube sections, the contact areas of the different main tube sections and the auxiliary heat exchange tubes 110 are substantially identical. Therefore, the overall performance reduction caused by uneven heat exchange in the local area is avoided, and the whole heat exchanger is ensured to have more consistent heat exchange efficiency on different main pipe sections.

Optionally, the plurality of main tube segments are divided into a first tube segment 210 and a second tube segment 220, wherein the heat exchange coefficient of the first tube segment 210 is smaller than the heat exchange coefficient of the second tube segment 220, and the winding interval of the auxiliary heat exchange tube 110 on the first tube segment 210 is smaller than the winding interval (not shown) of the auxiliary heat exchange tube 110 on the second tube segment 220.

In this embodiment, by distinguishing the pipe sections with different heat exchange coefficients and adjusting the winding interval of the auxiliary heat exchange pipe 110 according to actual needs, the heat exchange performance of the whole heat exchanger can be optimized. For the first type pipe section 210 with a smaller heat exchange coefficient, by reducing the winding interval of the auxiliary heat exchange pipe 110, the heat exchange area of the auxiliary heat exchange pipe 110 after winding can be increased, and the heat exchange efficiency can be improved, so that the defect of the heat exchange coefficient can be overcome. And for the second type pipe section 220 with a larger heat exchange coefficient, the efficient heat exchange performance can be maintained by proper winding intervals, and meanwhile, the cost is saved.

Optionally, the first outlet 102 communicates with the second inlet 111 through a flow control valve.

In this embodiment, the flow control valve can accurately control the flow of the refrigerant, so as to ensure that the flow between the first outlet 102 and the second inlet 111 meets certain specific working condition requirements. And through the regulation of the flow control valve, the flow stability of the whole heat exchanger can be kept, and further the performance degradation of the heat exchanger caused by flow fluctuation is prevented.

Optionally, the heat exchanger further comprises a heat exchange fan 130, and the heat exchange fan 130 is disposed at one side of the main heat exchange tube 100.

In this embodiment, when the heat exchange fan 130 is operated, forced convection may be generated, so that air flows through the main heat exchange tube 100 and the auxiliary heat exchange tube 110 more rapidly and uniformly, thereby enhancing heat exchange effect between the air and the pipes. In this way, it is advantageous to transfer heat from the duct to the air or from the air to the duct rapidly, thereby improving the overall heat exchange efficiency of the heat exchanger.

The embodiment of the disclosure also provides an air conditioner, which comprises the heat exchanger described in any embodiment.

As shown in connection with fig. 2-5, embodiments of the present disclosure provide a second heat exchanger including a main heat exchange tube 100, a heat exchange fan 130, and heat exchange fins 200. The heat exchange fan 130 is used for enabling air to flow from the first side to the second side of the main heat exchange tube 100, the heat exchange fins 200 are configured into a wing shape and are arranged on the main heat exchange tube, two ends of each heat exchange fin 200 are respectively called a wing front edge 201 and a wing rear edge 202, the width of each heat exchange fin 200 is called a wing thickness, the wing front edge 201 is located on the first side of the main heat exchange tube 100, the wing rear edge 202 is located on the second side of the main heat exchange tube 100, and therefore different wind speeds are formed on two sides of each heat exchange fin 200 in the wing thickness direction.

In this embodiment, forced convection is created by the heat exchange fan 130 effectively directing air from the first side to the second side of the primary heat exchange tube 100. And, the airfoil-shaped heat exchange fin 200 is designed to ingeniously utilize the Bernoulli effect of fluid mechanics. The arrangement where the leading edge 201 is on a first side and the trailing edge 202 is on a second side of the main heat exchanger tube 100 allows air to flow across the fins at different air flow rates on both sides in the direction of the wing thickness. As shown in fig. 4, the wind speed at the upper side in the thickness direction is greater than the wind speed at the lower side in the thickness direction. In this way, the heat exchange fin 200 forms different heat exchange efficiencies at both sides in the thickness direction, and the heat exchange efficiency of the upper part in the thickness direction is greater than that of the lower part. Therefore, the installation layout of the main heat exchange tube and the heat exchange fins 200 can be optimized according to the heat exchange requirements of different main heat exchange tubes.

In the present embodiment, the bernoulli effect is a physical phenomenon that describes a phenomenon in which an increase in velocity causes a decrease in pressure when a fluid (e.g., liquid or gas) flows in a pipe or a narrow area. According to the Bernoulli effect, when air flows past the surface of the upper side of the wing, the air flow path is longer and the flow rate is relatively faster due to the camber of the surface of the upper side. While the air path through the surface of the underside of the wing is relatively short and the flow rate is relatively slow.

Alternatively, the main heat exchange tube 100 includes a plurality of main tube sections divided into a first type tube section 210 (main tube section shown by solid line in fig. 3) and a second type tube section 220 (main tube section shown by broken line in fig. 3), wherein the heat exchange coefficient of the first type tube section 210 is smaller than that of the second type tube section 220, and the first type tube section 210 is disposed near an upper portion of the heat exchange fin 200 in the thickness direction and the second type tube section 220 is disposed near a lower portion of the heat exchange fin 200 in the thickness direction.

In the present embodiment, by arranging the main pipe sections of different heat exchange coefficients at different positions of the heat exchange fin 200, optimization of heat exchange efficiency can be achieved. Because the heat exchange efficiency of the heat exchange fin 200 at the upper part of the wing thickness direction is higher, the first pipe section 210 with a smaller heat exchange coefficient is arranged in the area, so that the efficient heat exchange characteristic of the first pipe section can be fully utilized, and the rapid heat transfer can be realized. Meanwhile, the heat exchange efficiency of the lower part in the wing thickness direction is relatively low, and the heat exchange performance of the first pipe section 210 with a larger heat exchange coefficient can be ensured by arranging the first pipe section in the area. Thus, through reasonable arrangement of the pipe sections, the overall heat exchange efficiency of the heat exchanger is improved.

Alternatively, the first type pipe section 210 and the second type pipe section 220 are respectively formed in a row and extend from the wing leading edge 201 to the wing trailing edge 202, and the first type pipe section 210 and the second type pipe section 220 are offset in the wing thickness direction.

In the present embodiment, the first-type tube segment 210 and the second-type tube segment 220 are arranged side by side in the wing thickness direction, which results in a larger width of the heat exchanger. The first pipe section 210 and the second pipe section 220 are arranged in a staggered manner in the wing thickness direction, so that the overall width of the heat exchanger can be effectively reduced. And, the staggered arrangement can optimize the connection structure between the main pipe sections and the heat exchange fins 200, so that the support between the main pipe sections is more balanced, and the structural stability of the whole heat exchanger is enhanced.

Optionally, only one first type tube segment 210 is arranged at the wing leading edge 201 of the heat exchange fin 200.

In the present embodiment, the heat exchange fins 200 are narrower at the wing leading edge 201, and in the case of a heat exchanger employing a double row primary heat exchange tube 100, only one first type tube segment 210 is disposed at the wing leading edge 201. In this way, adapting the airfoil shape of the heat exchange fin 200 optimizes the layout of the main heat exchange tube 100. And, the wing leading edge 201 is located upstream in the air flow direction, facilitating heat exchange with the first type of pipe section 210 having a smaller heat exchanger coefficient.

Optionally, only one second type tube segment 220 is arranged at the trailing edge 202 of the heat exchanging fin 200.

In the present embodiment, the heat exchange fins 200 are narrower at the trailing edge 202, and in the case of a double row primary heat exchange tube 100, only one second type tube segment 220 is disposed at the trailing edge 202. In this way, adapting the airfoil shape of the heat exchange fin 200 optimizes the layout of the main heat exchange tube 100.

Alternatively, the refrigerant flows from the first type of tube segment 210 to the second type of tube segment 220.

In this embodiment, the temperature of the refrigerant flowing into the first-type pipe section 210 is relatively high, and under the action of the wing-shaped heat exchange fins 200, the refrigerant is beneficial to efficiently exchange heat in the first-type pipe section 210 because the first-type pipe section 210 is arranged near the upper portion of the heat exchange fins 200 in the wing thickness direction.

Alternatively, as shown in fig. 2 and 5, the same heat exchange fin 200 is provided through all the main tube sections.

In this embodiment, the same heat exchange fin 200 is inserted into all the main tube sections, so that all the main tube sections are tightly connected together to form an integral structure. This design enhances the overall stability of the heat exchanger and reduces performance degradation due to loosening or deformation of the components.

Alternatively, all the main tube sections are arranged in parallel in the axial direction, and the plurality of heat exchange fins 200 are arranged at uniform intervals in the axial direction of the main tube sections.

In the embodiment, the axial parallel arrangement of all the main pipe sections ensures that the refrigerant can flow stably and uniformly in the pipeline, and reduces the resistance of the refrigerant flow and the formation of vortex. This helps to reduce energy loss and improve heat exchange efficiency. And, a plurality of heat exchange fins 200 are uniformly arranged at intervals, so that each heat exchange fin 200 can uniformly exchange heat with the main pipe section, thereby realizing uniform distribution and transfer of heat.

Optionally, all heat exchange fins 200 are parallel to each other.

In this embodiment, the parallel design of the heat exchange fins 200 makes the manufacturing process simpler and standardized. In addition, when maintaining and replacing the fins, the heat exchange fins 200 are orderly arranged, so that the operation is more convenient, and the maintenance cost and time can be reduced.

The embodiment of the disclosure also provides an air conditioner, which comprises the heat exchanger described in any embodiment.
