Example 1
As shown in fig. 1-4, the present embodiment discloses a heat pump unit 1 capable of uniformly distributing air, the heat pump unit 1 has a fin heat exchanger 2 and a fan 3, a symmetry line of the fin heat exchanger 2 coincides with an axial line of the fan 3, the fan 3 is disposed at one side of the fin heat exchanger 2, and the fin heat exchanger is provided with a plurality of fins 4 parallel to each other; under the action of the fan 3, air flows through the fin heat exchanger 2 from one side of the fin heat exchanger 2 and flows out from the other side.
As shown in fig. 4, the fin heat exchanger 2 is U-shaped in cross section parallel to the air flow direction.
The fin heat exchanger 2 is divided into three areas according to the distance from the axial lead of the fan: the fan comprises a low-pressure area S1, a middle-pressure area S2 and a high-pressure area S3, wherein the distance from the low-pressure area S1 to the axis of the fan is small, the distance from the middle-pressure area S2 to the axis of the fan is larger than that from the low-pressure area to the axis of the fan but smaller than that from the high-pressure area, and the distance from the high-pressure area S3 to the axis of the fan is large.
The fins of the low-pressure area S1 part of the fin type heat exchanger are relatively large in spacing, the fins of the medium-pressure area part of the fin type heat exchanger are relatively small in spacing, the fins of the low-pressure area part of the fin type heat exchanger are relatively large in spacing, and the fins of the high-pressure area part of the fin type heat exchanger are relatively small in spacing. For example, the fin pitch of the S1 portion was 2.5mm, the fin pitch of the S2 portion was 2.2mm, and the fin pitch of the S3 portion was 1.8 mm. The numerical values are merely examples, and it is understood that the specific numerical values may be changed according to actual needs.
It can be understood that the division of the low-pressure area, the medium-pressure area and the high-pressure area is determined according to the wind pressure of the environment where different areas on the fin heat exchanger are located. In a specific embodiment, the fan 3 is an axial flow fan, and the fins of the finned heat exchanger 2 are aluminum foils. When the axial flow fan 3 rotates, the negative pressure of a closed space enclosed by the fan, the wind shield and the fin heat exchanger is different in magnitude, no fan blade is arranged in an area near the center of a motor shaft or the inclination angle of the fan blade is very small, the static pressure of an area right below the motor is very small when the fan blade rotates, so that the flow rate of wind is relatively low, the pressure of the fan blade in the radial direction is increased, the pressure at the edge is maximum, the flow rate of air corresponding to the air below and the pressure form a positive correlation rule, the air flow rate under edge projection is high, and the air flow rate is slower when the fan blade is closer to the center. On the other hand, the fins on the fin heat exchanger are used for increasing the heat exchange area and improving the heat exchange effect, the more the aluminum foils are, the larger the area is, the more the heat exchange is facilitated, but the smaller the aluminum foil interval is, the larger the wind resistance is, the more the heat exchange is not facilitated, and the two are contradictory. How to realize the balance between the wind resistance and the heat exchange area is the key to realize high heat exchange efficiency. The experiment verifies that the comparison data shows that the wind resistance is larger, the aluminum foil interval is properly increased to reduce the wind resistance, and the wind speed is improved to be more favorable for heat exchange. Therefore, by combining the structural characteristics of the axial flow fan and the relationship between the fin spacing and the wind resistance, the fin heat exchanger is divided into high-pressure areas, medium-pressure areas and low-pressure areas according to different wind pressures, the high-pressure areas have high static pressure, the aluminum foil spacing is small, the low-pressure areas have low static pressure, and the aluminum foil spacing is large, so that the heat exchange effect is improved.
The embodiment can achieve the following technical effects:
the fin heat exchanger is divided into three areas of high, medium and low according to the height difference of the wind pressure where the fin heat exchanger is located, the fin intervals in different areas are different, the area of the fin heat exchanger is reduced on the whole, the material cost is reduced, the occupied space of the fin heat exchanger is reduced, the fin heat exchange efficiency is improved, the economy of a heat pump is improved, and a good technical effect is achieved.
