TECHNICAL FIELD

[0001] The utility model relates to air cooling unit technical field, concretely relates to a heat recovery air cooling unit. BACKGROUND

[0002] As a refrigeration equipment, air cooling unit realizes refrigeration through heat transfer between evaporator and condenser. In traditional air cooling unit, refrigerant becomes gaseous after absorbing heat in evaporator, and then is pressurized and heated by compressor, and finally is liquefied in condenser and re-enters evaporator to complete refrigeration cycle. However, this process produces a large amount of waste heat, which is directly discharged into the atmosphere, causing energy waste and environmental pollution. In order to improve energy efficiency, reduce cost and reduce environmental impact, heat recovery technology is introduced into air cooling unit.

[0003] Existing heat recovery technologies include heat pump technology, heat exchanger technology, etc. These technologies improve energy utilization rate by recycling and reusing waste heat. Among them, using water as heat exchange medium is a common way. Water has high specific heat capacity and can effectively absorb heat, so it is widely used in heat recovery systems.

[0004] Although the existing air cooling unit heat recovery technology improves energy utilization efficiency to some extent, there are still some problems. For example, some existing heat recovery systems often use integral water tank, which lacks effective partition design, resulting in the need for overall heat exchange of a large amount of water, so that some water cannot be fully heat exchanged with the heat exchanger, and the heat exchange efficiency is low. SUMMARY

[0005] Therefore, the utility model provides a heat recovery air cooling unit, which can avoid the problem that some water cannot be fully heat exchanged, so that water can be more fully heat exchanged, and the heat exchange efficiency is improved.

The middle part of the rack is provided with an evaporator, one side of the top of the rack is fixedly connected with a compressor, the inlet of the compressor is connected in series with the outlet of the evaporator, the top of the rack is provided with a recovery assembly, the recovery assembly comprises a recovery tank fixedly connected to the other side of the top of the rack, the upper side of the middle part of the rack in the recovery tank is fixedly connected with a heat exchanger, the input end of the heat exchanger is connected in series with the output end of the compressor through a pipeline, the water outlet of the heat exchanger is connected in series with the input end of the evaporator, the middle part of the recovery tank is fixedly connected with a plurality of arrayed partition plates, the middle part of the recovery tank is divided into a plurality of recovery chambers by the partition plates, water outlets are formed on both sides of each recovery chamber, which avoids the problem that some water cannot be fully heat exchanged with the heat exchanger when facing large flow of water, so that water in different areas can be more quickly and fully heat exchanged, and the heat exchange efficiency is improved.

[0007] The recycling assembly further comprises a fin plate fixedly connected to the top of the heat exchanger; that is, it helps to improve the heat energy recycling efficiency.

[0008] The top of the rack is further provided with a protection assembly, and the protection assembly comprises a protection frame fixedly connected to the top of the rack; that is, the protection performance of the equipment is enhanced.

[0009] The middle part of the protection frame is fixedly connected with an isolation plate; that is, the heat in the heat exchanger is prevented from being directly transmitted to the compressor, so as to affect the normal work of the compressor.

[0010] The top of the isolation plate and the protection frame is fixedly connected with the same protection cover; that is, the heat preservation performance of the heat exchange area is enhanced, and the heat loss is reduced.

[0011] The top of the protection frame is fixedly connected with a cover plate on the side close to the compressor; that is, foreign matters are prevented from entering, and the compressor is protected.

[0012] The side of the water gap is fixedly connected with a connecting head; that is, the connection of the water pipe and the water gap is more convenient.

[0013] Compared with the prior art, the present application has at least one of the following beneficial technical effects:

[0024] In order to make the purpose, technical solutions and advantages of the embodiment of the present invention clearer, the following will be combined with the appended drawings of the embodiment of the present invention. Figures 1-4 , clearly and completely describing the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of the present invention.

[0025] like Figures 1-4 As shown: This embodiment provides an air-cooled unit with heat recovery, including a frame 100 and a recovery component 200. An evaporator 101 is installed in the middle of the frame 100. A compressor 102 is fixedly connected to one side of the top of the frame 100. The inlet of the compressor 102 is connected in series with the output end of the evaporator 101. A recovery component 200 is provided on the top of the frame 100. The recovery component 200 includes a recovery box 201 fixedly connected to the other side of the top of the frame 100. The frame 100 is located in the recovery box 201. A heat exchanger 202 is fixedly connected to the upper side of the middle part. The input end of the heat exchanger 202 is connected in series with the output end of the compressor 102 through a pipeline. The water outlet 204 of the heat exchanger 202 is connected in series with the input end of the evaporator 101. A plurality of partitions 203 distributed in an array are fixedly connected to the middle part of the recovery box 201. The middle part of the recovery box 201 is divided into a plurality of recovery chambers by the partitions 203. Water inlets 204 are opened on both sides of each recovery chamber, one side is a water inlet 204, and the other side is a water inlet 204.

[0026] When the air-cooled unit is running, the refrigerant absorbs heat in the evaporator 101 and becomes gaseous refrigerant, then flows into the compressor 102, which pressurizes and heats the gaseous refrigerant to become high-temperature and high-pressure gas, which then flows into the heat exchanger 202. The refrigerant synchronously releases heat in the heat exchanger 202, and the heat exchanger 202 is located in the recovery tank 201, which is divided into multiple recovery chambers by the partition 203. Each recovery chamber has a water inlet 204 and a water outlet 204 to guide the external normal-temperature water into each recovery chamber to cool different areas of the heat exchanger 202 and exchange heat with the refrigerant inside the heat exchanger 202. The refrigerant releases heat and its temperature decreases. Then, the refrigerant cooled by the heat exchanger 202 flows out of the heat exchanger 202 and into the evaporator 101 through a pipeline. In the evaporator 101, the low-temperature and high-pressure liquid refrigerant absorbs heat from the external air, evaporates, and becomes gaseous refrigerant again, while releasing cold energy for refrigeration purposes. At this time, the external air is cooled, flows through the evaporator 101, and is discharged from the air-cooled unit, realizing the heat recovery air-cooled unit.

[0027] Through the design of the heat exchanger 202 and the partition 203 of the water tank, the waste heat is recovered and reused. The warm water can be used for heating, domestic hot water, or other occasions that require hot water, improving energy utilization and reducing energy waste and environmental pollution. At the same time, since the water tank is divided into multiple recovery chambers by the partition 203, each recovery chamber can independently perform heat exchange, making the heat exchange more localized. The heat exchanger 202 can perform heat exchange on smaller flow of water, without the need for overall heat exchange on a large amount of water, avoiding the problem of some water being unable to sufficiently exchange heat with the heat exchanger 202 when facing large flow of water. This allows water in different areas to exchange heat more quickly and sufficiently, improving the efficiency of heat exchange. The partition design allows each recovery chamber to be independently accessed, which facilitates maintenance and cleaning of the heat exchanger 202.

[0028] The fin plate 205 is as shown in Figure 2 、 3 ,

[0029] The recovery assembly 200 further includes a fin plate 205 fixedly connected to the top of the heat exchanger 202.

[0030] The fin plate 205 can increase the heat exchange efficiency between the water flow in the recovery tank 201 and the heat exchanger 202, allowing the water flow to more fully contact the heat exchanger 202 when passing through the recovery tank 201, thereby improving the efficiency of heat exchange.

[0031] The protection assembly 300 is as shown in Figure 1 、 2 ,

[0032] The top of the rack 100 is further provided with a protection assembly 300, which comprises a protection frame 301 fixedly connected to the top of the rack 100, and the compressor 102 and the heat exchanger 202 are both located inside the protection frame 301.

[0033] The protection frame 301 can protect the compressor 102 and the heat exchanger 202 from direct contact with the outside world, preventing dust, debris or other external factors from damaging the compressor 102 and the heat exchanger 202.

[0034] The isolation plate 302 is as shown in Figure 4 ,

[0035] The middle part of the protection frame 301 is fixedly connected with the isolation plate 302.

[0036] The isolation plate 302 separates the heat exchanger 202 from the compressor 102, so that the heat exchanger 202 and the compressor 102 can independently perform heat exchange and compression work when running without interfering with each other. Preventing the heat in the heat exchanger 202 from being directly transmitted to the compressor 102, affecting the normal work of the compressor 102.

[0037] The protection cover 303 is as shown in Figure 1 , 2 , 3,

[0038] The isolation plate 302 and the top of the protection frame 301 are fixedly connected with the same protection cover 303, and the size of the protection cover 303 is greater than that of the recovery tank 201, and the protection cover 303 is located directly above the recovery tank 201.

[0039] The protection cover 303 can enhance the heat preservation performance of the heat exchange area, reduce heat loss and improve heat exchange efficiency.

[0040] The cover plate 304 is as shown in Figure 1 ,

[0041] The side of the top of the protection frame 301 close to the compressor 102 is fixedly connected with the cover plate 304.

[0042] The cover plate 304 and the protection frame 301 can cooperate to protect the top and side of the compressor 102, preventing dust, moisture and other external impurities from entering the inside of the compressor 102, and protecting the compressor 102 from damage.

[0043] The connecting head 103 is as shown in Figure 1 , 2 ,

[0044] One side of the water inlet 204 is fixedly connected with the connecting head 103.

[0045] Through the connecting head 103, the water pipe can be conveniently connected with the water inlet 204, so as to realize the inflow and outflow of water into and out of the recovery tank 201.

[0046] In addition, it also needs to be explained that, in the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0047] The above is the preferred embodiment of the present application, it should be pointed out that, for those skilled in the art, without departing from the principles described in the present application, a number of improvements and refinements can be made, these improvements and refinements should also be considered as the protection scope of the present application.
