technical field

The utility model belongs to the technical field of refrigeration equipment, in particular to an evaporative cooling water circulation system of refrigeration equipment.

Background technique

In the prior art, refrigeration equipment usually uses a water circulation system and a heat exchanger to fully cool the refrigerant. After the cooling water exchanges heat with the refrigerant, it needs to be cooled again so as to cool the refrigerant cyclically. Compared with the traditional way of cooling the cooling water by cooling fans, evaporative condensation cooling has the characteristics of fast cooling rate and low cooling energy consumption.

For example, the Chinese Utility Model Patent No. CN201720573344.0 discloses an evaporative condensation temperature adjustment device, which includes a frame, on which a lower chamber and an evaporation chamber located above the lower chamber are arranged. The evaporating chamber is provided with an evaporative cooling mechanism and a water distribution mechanism for supplying water to the evaporative cooling mechanism, and the lower chamber is provided with a water collection and recovery mechanism for recycling the cooling water flowing through the evaporative cooling mechanism. The water distribution mechanism, the evaporation heat dissipation mechanism, and the water collection and recovery mechanism are connected in series to form a water circulation loop. The water circulation loop is connected in series with a circulating water pump. The water circulation loop is connected to a heat exchanger arranged in the lower chamber and can pass heat The exchanger exchanges heat with the refrigerant circuit.

Wherein, the evaporation cooling mechanism on the circulation circuit includes several evaporation plates for increasing the evaporation area and a negative pressure fan for accelerating the air flow in the evaporation chamber to form a negative pressure. The evaporation plates are detachably connected to the frame, and each evaporation plate The plate and the negative pressure fan enclose the evaporation chamber; the evaporation plate includes an evaporation plate frame, and the evaporation plate frame is provided with a wet curtain stacked paper filled with the evaporation plate frame, and the evaporation plate frame is far away from the evaporation chamber. An outer cover is arranged on the side, and a filter partition is arranged between the outer cover and the evaporating plate frame, and the upper end and the lower end of the evaporating plate frame are respectively provided with a water inlet tank and a water outlet tank; The water supply pipe connected to the water collection and recovery mechanism extends upward to the evaporation chamber, and a number of end-to-end water distribution pipes are connected to the water supply pipe, and the water distribution pipes are arranged in the water inlet tank.

The disadvantage of this evaporative condensing temperature adjustment device is that the cooling water entering the water supply pipe needs to flow through the end-to-end water distribution pipe first, and then flow out from the water outlet hole on the wall of the water distribution pipe to the horizontally arranged on the upper end of the evaporation plate frame. In the water inlet tank; in order to ensure that the cooling water can fill the water distribution pipe, the opening size of the water outlet hole is generally small, and the flow rate of the cooling water is generally slow. The hole is often blocked and requires frequent maintenance, and the narrow water distribution pipe makes maintenance inconvenient. Usually, it will be replaced after being blocked, resulting in increased maintenance costs.

Utility model content

The purpose of the invention of this application is to provide an evaporative cooling water circulation system of refrigeration equipment that is not easy to be blocked and has a low maintenance rate.

In order to realize the above-mentioned purpose of the invention, the technical scheme of the present application is as follows:

An evaporative cooling water circulation system for refrigeration equipment, including a frame, in which a water collection and recovery mechanism, a water distribution mechanism, and an evaporative heat dissipation mechanism connected in series are arranged, and the evaporative heat dissipation mechanism includes at least three evaporating plates, all The evaporating plates form an evaporating chamber, and the top of each evaporating plate is provided with a water inlet groove; the water distribution mechanism includes:

The water supply pipe connected to the water collection and recovery mechanism;

In this application, each water distribution pipe is connected to the water supply pipe separately. The number of water distribution pipes is the same as the number of evaporation plates or a multiple of the number of evaporation plates. The cooling water in the water distribution pipes first flows into the top surface of the water distribution plate from the water outlet hole. , and then flow into the water inlet tank of the corresponding evaporator plate along the top surface through the drain edge. During the entire cooling water distribution process, the cooling water does not pass through any right-angled bends. The cooling water flowing out of the hole is dispersed to the natural drain edge of the water distribution plate, and the cooling water flows into the water inlet tank from the entire drain edge. The surface of the water supply pipe, water distribution pipe and water distribution plate is not easy to accumulate dirt, and the water distribution channel is not easy to be blocked. , which greatly reduces the maintenance rate; even if a blockage occurs, it is only necessary to clean the water distribution pipe, the water outlet hole and/or the top surface of the water distribution plate, and the maintenance cost is low.

In order to connect with the water inlet, the projection of the discharge edge on the water inlet should also be in a straight line consistent with the water inlet. This leads to the formation of a triangular zone between the water outlet edge and the water outlet hole, and the distance between the water outlet hole and various parts of the water outlet edge is not the same, which makes it difficult for the cooling water to evenly disperse to each part of the water outlet edge. Therefore, in the above-mentioned evaporative cooling water circulation system of the refrigeration equipment, the top surface of the water dividing plate is arched, and the arched top surface is arranged symmetrically with respect to the line connecting the middle point of the water discharge edge and the center of the water outlet hole; Between the water outlet hole and the water discharge edge, the top surface of the water diversion plate is provided with a diversion structure. After the top surface of the water distribution plate is set in an arched shape, the edge of the water discharge can still be connected to the water inlet tank, but it can make the time required for the cooling water flowing out of the water outlet to reach all parts of the edge of the water discharge to be consistent. The midpoint is arched At the top of the top surface, the distance between the water outlet hole and the midpoint of the drain edge is short but the flow rate of the cooling water is slow; from the midpoint of the drain edge to the two ends of the drain edge, the water flow speed gradually becomes faster), while the shunt structure can Promote the cooling water to disperse evenly to the edge of the drain, facilitate the full use of the evaporating plate, and improve the evaporation and heat dissipation rate of the evaporating plate for the cooling water.

In the above-mentioned evaporative cooling water circulation system of the refrigeration equipment, all the diverging spokes extend from the outer periphery of the overflow table to the edge of the water discharge.

In the above-mentioned evaporative cooling water circulation system of the refrigeration equipment, a deflector integrated with the water diversion plate is provided between the water discharge edge and the water inlet tank, and the direction of extension of the deflector is opposite to that of the water diversion plate. The splitter spokes extend from the edge of the water discharge to the edge of the deflector. After the deflector is provided, the cooling water can flow into the water inlet groove along the deflector, and will not spray from the water discharge edge to the outside of the water inlet groove.

Due to the small area of the overflow platform and the long length of the discharge edge, it is inconvenient to set the diverter spokes too closely on the outer periphery of the overflow platform, and it is difficult to ensure the same flow in all the diverter channels with looser diverter spokes. Therefore, in the above-mentioned evaporative cold water circulation system of the refrigeration equipment, at least one guide spoke is provided between adjacent diverter spokes, and the guide spoke extends from the edge of the guide plate to the edge of the drain; A guide channel is formed between two guide spokes, and between adjacent diverter spokes and guide spokes, and each guide channel is set with the same width. The diversion spokes can divide the cooling water flow in each diversion channel into three levels to ensure that the flow in each diversion channel is consistent and ensure that the cooling water is evenly dispersed into the water inlet tank.

In the evaporative cold water circulation system of the above-mentioned refrigeration equipment, the top surface of the water dividing plate is an obtuse isosceles triangle, and the water stop plate extends from the apex of the isosceles triangle along the waist of the isosceles triangle to the deflector Both ends protrude beyond the front of the deflector. The water stop plate can prevent the cooling water flowing from the water outlet hole from flowing into the evaporation chamber, and the water stop plate extends and protrudes in front of the deflector to surround the cooling water flowing down the deflector, preventing the cooling water from leaking out and ensuring cooling The water all flows into the sink.

In the above-mentioned evaporative cold water circulation system of the refrigeration equipment, an embedded groove at the bottom of the water overflow table is provided on the back of the water diversion plate, and a water outlet extending to the top surface of the water overflow table is formed in the embedded groove. pipe, the water outlet end of the water distribution pipe is set outside the water outlet pipe and embedded in the embedded groove; on the top surface of the overflow table, the side wall of the water outlet pipe is formed with a diffuser facing the diversion spokes. sink. The embedded grooves and water outlet pipes facilitate quick installation and disassembly of the water distribution pipes and water distribution plates, while the overflow grooves facing the diversion spokes prevent the cooling water gushing from the water outlet holes from rushing to the water stop plate and affecting the diversion of cooling water.

In the above-mentioned evaporative cold water circulation system of the refrigeration equipment, the bottom of the evaporation plate is provided with a water outlet tank, and the water collection and recovery mechanism includes a water receiving tray under the water outlet tank, and the outer peripheral edge of the water receiving tray With a water-retaining edge, the center of the water-receiving pan is provided with an overflow pipe protruding from the top surface of the water-receiving pan, and a water-receiving tank is formed between the overflow pipe and the water-retaining edge, and the inner plate of the water-receiving tank is provided with Refrigerant pipes. In this application, the refrigerant tube coil is directly arranged in the water receiving tray, and after the cooling water cooled by the evaporative cooling mechanism enters the water receiving tank, the refrigerant tube can be cooled immediately while collecting water.

In the above-mentioned evaporative cooling water circulation system of the refrigeration equipment, a plurality of strip-shaped overflow grooves are formed on the outer peripheral wall of the overflow pipe, and all the overflow grooves extend axially along the overflow pipe to the end of the overflow pipe. At the top opening, the lengths of two adjacent overflow grooves are different. After heat exchange with the refrigerant pipe, the cooling water in the water receiving pan heats up again. If only the uppermost cooling water flows out through the overflow port, the high temperature cooling water in the lower layer of the water receiving pan will stay in the water receiving pan inside, resulting in poor cooling effect of the refrigerant tube. The overflow tanks with different lengths enable the cooling water at various depths of the water receiving tanks to flow out through the overflow pipes, realizing rapid replacement of cooling water, thereby improving heat exchange efficiency.

Compared with the prior art, the beneficial effect of the utility model is: the application connects each water distribution pipe to the water supply pipe separately, the number of water distribution pipes is consistent with the number of evaporating plates or is a multiple of the number of evaporating plates, and the water distribution pipes The cooling water first flows into the top surface of the water distribution plate from the water outlet hole, and then flows into the water inlet groove of the corresponding evaporator plate along the top surface through the drain edge. During the entire cooling water distribution process, the cooling water does not pass through any Right-angled bend, the diameter of the water outlet hole is equivalent to that of the water distribution pipe, the cooling water flowing out from the water outlet hole is dispersed to the natural discharge edge of the water distribution plate, the cooling water flows into the water inlet tank from the entire discharge edge, the water supply pipe, water distribution pipe and Dirt is not easy to accumulate on the surface of the water distribution plate, and the water distribution channel is not easy to be blocked, which greatly reduces the maintenance rate; even if a blockage occurs, it is only necessary to clean the water distribution pipe, water outlet hole and/or the top surface of the water distribution plate, and the maintenance cost is low.

In the overflow pipe 23 , the top edge of the water retaining edge 222 is higher than the overflow port 231 of the overflow pipe 23 , and a water receiving groove 223 is formed between the overflow pipe 23 and the water retaining edge 222 .

As shown in Figure 1, in conjunction with Figure 2 and Figure 3, it can be seen that the water distribution mechanism 3 of the present embodiment includes a water supply pipe 32 connected to the water collection tank 21 through a circulating water pump 31, and the water supply pipe 32 is upward from the lower chamber 11 (through the connection The water tray 22, or extends from the outer periphery of the water tray 22) into the evaporation chamber 12, and is connected to four water distribution pipes (not shown in the figure) respectively through a five-way connector (not shown in the figure), each branch The water pipes are all connected to a water diversion plate 33 , and each water diversion plate 33 is installed above the water inlet groove 415 of the corresponding evaporation plate 41 .

As shown in Fig. 2 and Fig. 3, the top surface of the water diversion plate 33 of the present embodiment is an obtuse-angled isosceles triangle, and at the apex of the isosceles triangle, the top surface of the water diversion plate 33 is convexly provided with a flood platform 34, which is divided into The back side of the water plate 33 is formed with an embedded groove 331 below the water overflow table 34, and a water outlet pipe 35 is formed in the embedded groove 331, and the water outlet pipe 35 extends reversely to the top surface of the water overflow table 34, and the water outlet hole 351 protrudes from the top surface of the water overflow table 34.

As shown in Figure 2, on the side wall of the overflow platform 34, a overflow groove 352 is formed on the side wall of the outlet pipe 35; The water discharge edge 332 at the bottom edge, in order to join with the water inlet groove 415, the projection of the water discharge edge 332 on the water inlet groove 415 should also be in a straight line consistent with the water inlet groove 415. This leads to a triangular zone formed between the water discharge edge 332 and the water outlet hole 351, and the distance between the water outlet hole 351 and the various parts of the water discharge edge 332 is not the same, which makes it difficult for the cooling water to evenly disperse to all parts of the water discharge edge 332 . Therefore, in this implementation, the top surface of the water diversion plate 33 is set to be arched (as shown in Figure 2), and the arched top surface is arranged symmetrically with respect to the line connecting the middle point of the water discharge edge 332 and the center of the water outlet hole 351; The water edge 332 has a deflector 36 integrated with the water diversion plate 33 (the side wall of the diversion plate 36 connected to the diversion plate 33 is also arched), and the deflector 36 extends towards the back of the diversion plate 33 And it is connected with the water inlet tank 415 .

The water edge 332 then continues to extend to the edge of the deflector 36 , and flow diversion channels 334 are formed between adjacent flow diversion spokes 333 . Due to being limited by the area of the overflow platform 34, the spacing between the diverter spokes 333 is indeterminate on the side of the water discharge edge 332; therefore, some diverter spokes 361 are also arranged on the deflector 36 in this implementation, and each diverter spoke 361 extends from the edge of the flow deflector 36 to the water discharge edge 332 , and the flow guide spokes 361 are located between the flow diversion spokes 333 , dividing each flow diversion channel 334 into flow guide channels 362 with equal widths.

And the connecting section 53 is also in an inverted U shape. The inverted U-shaped setting above the liquid level of the water receiving tray 22 enables the high temperature section of the access section 51 to dissipate heat first under the action of the fan of the evaporative cooling mechanism 4; and the inverted U-shaped setting above the liquid surface of the water receiving tray 22 makes The outlet section 53 is far away from the cooling water heated up by heat exchange, and is connected to the evaporative cooling oil circulation system after cooling again under the action of the fan of the evaporative heat dissipation mechanism 4; thereby further improving the heat dissipation effect of the refrigerant.
