[0035] Household appliances such as refrigerators and air conditioners all require a refrigeration system for cooling. In related technologies, the refrigeration system is integrated with the electrical equipment. The refrigerant pipelines of the refrigeration system need to be pre-buried in the electrical equipment, and then the various refrigeration components in the refrigeration system need to be welded. Therefore, the refrigeration system cannot be processed and designed modularly. When installing the refrigeration system on the production line, the installation, welding, vacuuming, adding liquid, sealing the pipe and other processes need to be performed on the entire chassis of the electrical equipment. The entire chassis of the electrical equipment is large in size and heavy in weight, resulting in a relatively larger production line, lower operator efficiency, and thus lower production efficiency.

[0036] In order to solve the problems existing in the relevant technologies to a certain extent, the embodiments of the present application provide a refrigeration module and electrical equipment, which enable the refrigeration module to be installed at any position of the electrical equipment without the need for an integrated setting, so that the refrigeration module and the electrical equipment can be designed and processed separately, thereby improving production efficiency.

[0037] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0038] See also Figures 1-6 The embodiment of the present application provides a refrigeration module 10 and an electrical device 1. The refrigeration module 10 and the electrical device 1 provided in the embodiment of the present application enable the refrigeration module 10 to be installed at any position of the electrical device 1 without the need for an integrated setting, so that the refrigeration module 10 and the electrical device 1 can be designed and processed separately, thereby improving production efficiency.

[0039] See also Figure 1-Figure 3 The present invention provides a refrigeration module 10 for use in an electrical device 1, comprising a housing 100, a compressor 200, a first heat exchanger 300, a second heat exchanger 400, and a throttle 500. The housing 100 has a refrigeration chamber 110, which has an air outlet 111 and an air inlet 112. The air outlet 111 and the air inlet 112 are configured to communicate with the housing 20 of the electrical device 1. The compressor 200, the first heat exchanger 300, and the throttle 500 are mounted on the housing 100 and disposed outside the refrigeration chamber 110. The second heat exchanger 400 is disposed within the refrigeration chamber 110.

[0040] The shell 100 is the basic component of the refrigeration module 10 of the present application. The shell 100 can provide an installation basis for the compressor 200, the first heat exchanger 300, the second heat exchanger 400 and the throttle 500 of the refrigeration module 10, and serves the purpose of protecting the compressor 200, the first heat exchanger 300, the second heat exchanger 400 and the throttle 500. Moreover, since the compressor 200, the first heat exchanger 300, the second heat exchanger 400 and the throttle 500 are all installed in the shell 100, the integration of the refrigeration module 10 can be improved, making it convenient to assemble the refrigeration module 10 with the electrical equipment 1.

[0041] The refrigeration principle of the refrigeration module 10 provided in the embodiment of the present application is as follows: after the compressor 200 is in operation, the internal refrigerant is compressed into a high-temperature, high-pressure superheated vapor, which is then discharged from the exhaust port of the compressor 200 and enters the first heat exchanger 300. The first heat exchanger 300 dissipates the heat of the refrigerant to the surrounding air, causing the refrigerant to condense from the high-temperature, high-pressure superheated vapor to a liquid at room temperature and high pressure. The refrigerant then passes through the drying filter and enters the throttling device 500. After entering the throttling device 500, the refrigerant is throttled and reduced in pressure to become a low-temperature, low-pressure refrigerant liquid. It then enters the second heat exchanger 400. In the second heat exchanger 400, the low-temperature, low-pressure refrigerant liquid absorbs the heat exchanged in the refrigeration chamber 110 and vaporizes into a saturated gas, thereby achieving the purpose of cooling the refrigeration chamber 110. Finally, the low-temperature, low-pressure refrigerant gas enters the compressor 200 through the compressor intake port, and the refrigerant undergoes the next cycle under the drive of the compressor 200. That is, the refrigeration module 10 provided in the embodiment of the present application is an independent module that can operate independently to achieve the refrigeration function. Since the refrigeration module 10 is applied to the electrical equipment 1, in other words, the embodiment of the present application integrates the various refrigeration elements used to cool the electrical equipment into an independent module, namely the refrigeration module 10. The refrigeration module 10 can be set separately from the electrical equipment 1.

[0042] Since the refrigeration cavity 110 has an air outlet 111 and an air inlet 112, the air outlet 111 and the air inlet 112 are used to communicate with the cabinet 20 of the electrical device 1. Therefore, the cold air in the refrigeration cavity 110 can circulate between the refrigeration cavity 110 and the cabinet 20 of the electrical device 1 through the air outlet 111 and the air inlet 112 to cool the cabinet 20 of the electrical device 1. That is, the cold air in the refrigeration cavity 110 can flow into the cabinet 20 of the electrical device 1 through the air outlet 111, and after cooling the cabinet 20 of the electrical device 1, it flows into the refrigeration cavity 110 through the air inlet 112, and after being cooled by the refrigeration module 10, it flows into the cabinet 20 of the electrical device 1 through the air outlet 111, and the cycle repeats. After the refrigeration module 10 is assembled to the electrical device 1, it is only necessary to connect the air outlet 111 and the air inlet 112 to the box 20 of the electrical device 1 to achieve cooling of the box 20. The refrigeration module 10 can be installed at any position of the electrical device 1 according to different needs. Therefore, the refrigeration module 10 and the electrical device 1 can be designed and processed separately and finally assembled together without having to be processed together at the same time, thereby improving the production efficiency of the electrical device 1.

[0043] Moreover, in the related art, since the refrigerant pipeline is buried in the foam layer of the box body 20, the refrigerant pipeline is not visible and cannot be disassembled during maintenance, so maintenance is difficult. However, in the present application, since the refrigeration module 10 and the electrical equipment 1 are arranged in a split type, the refrigeration module 10 and the electrical equipment 1 can be separated during maintenance, which greatly improves the convenience of maintenance.

[0044] Specifically, the first heat exchanger 300 is a condenser, the second heat exchanger 400 is an evaporator, and the throttling element 500 is a capillary tube. The condenser dissipates heat from the refrigerant to the surrounding air, while the refrigerant is throttled and depressurized by the capillary tube, becoming a low-temperature, low-pressure refrigerant liquid. The evaporator absorbs heat from the heat exchange medium in the storage box, thereby cooling the heat exchange medium. In other words, the evaporator directly cools the refrigeration chamber 110, while the compressor 200 operates at a higher temperature. Therefore, placing the second heat exchanger 400 separately in the refrigeration chamber 110 reduces the heat dissipated from the compressor 200 into the refrigeration chamber 110, resulting in higher cooling efficiency for the refrigeration chamber 110 and, consequently, for the cabinet 20.

[0045] In some embodiments, see Figure 3 The refrigeration module 10 further includes a mounting plate 600 , which is connected to the housing 100 , and the compressor 200 and the first heat exchanger 300 are disposed on the mounting plate 600 .

[0046] Since the compressor 200 and the first heat exchanger 300 are located outside the refrigeration chamber 110, to facilitate installation of the compressor 200 and the first heat exchanger 300, the compressor 200 and the first heat exchanger 300 are both disposed on the mounting plate 600. Specifically, the compressor 200 and the first heat exchanger 300 are both provided with a first connector 610, and the mounting plate 600 is correspondingly provided with a second connector 210. The first connector 610 is connected to the second connector 210 to enable the compressor 200 and the first heat exchanger 300 to be fixedly connected to the mounting plate 600. Since the mounting plate 600 is connected to the housing 100, the compressor 200 and the first heat exchanger 300 are thereby mounted on the housing 100.

[0047] In order to facilitate maintenance or replacement of the compressor 200 and the first heat exchanger 300, the first connector 610 and the second connector 210 can be connected in a detachable manner such as screw connection or snap connection, which is not limited.

[0048] In some embodiments, a heat insulating layer 700 is disposed between the mounting plate 600 and the housing 100 .

[0049] Since the compressor 200 generates heat during operation, and the second heat exchanger 400 needs to cool the refrigeration cavity 110 so that the cold air in the refrigeration cavity 110 can cool the cabinet 20 of the electrical device 1, it is necessary to reduce the amount of heat transferred from the compressor 200 to the refrigeration cavity 110 to ensure the cooling effect of the second heat exchanger 400. Since the compressor 200 is mounted on the mounting plate 600 and the refrigeration cavity 110 is disposed in the housing 100, an insulating layer 700 is provided between the mounting plate 600 and the housing 100 to effectively insulate and reduce the amount of heat transferred from the compressor 200 to the refrigeration cavity 110.

[0050] Specifically, the heat insulation layer 700 can be made of heat insulation materials such as aerogel felt and vacuum panels, and there is no limitation to this.

[0051] In some embodiments, the refrigeration module 10 further includes a radiator 800 , which is disposed between the compressor 200 and the first heat exchanger 300 .

[0052] Because the first heat exchanger 220 dissipates heat from the refrigerant to the surrounding air, condensing the refrigerant from high-temperature, high-pressure superheated vapor into a liquid at room temperature and high pressure, the placement of a radiator 250 around the first heat exchanger 220 can accelerate the flow of air around the first heat exchanger 220, allowing the refrigerant's heat to dissipate more quickly, thereby improving refrigeration efficiency. Furthermore, because the radiator 250 is positioned between the compressor 210 and the first heat exchanger 220, it can also simultaneously accelerate the flow of air around the compressor 210, thereby dissipating heat from the compressor 210 and reducing the risk of the compressor 210 overheating during operation. In other words, the placement of a single radiator 250 can dissipate heat from both the first heat exchanger 220 and the compressor 210, making the layout of the various components of the first refrigeration assembly 200 more compact and occupying less space.

[0053] Specifically, the radiator 800 may be a cooling fan, and the blowing of the cooling fan may accelerate the air flow, thereby causing the heat to dissipate faster.

[0054] In some embodiments, the refrigeration module 10 further includes a heat dissipation cover 900 , which is disposed to cover the radiator 800 and the first heat exchanger 300 .

[0055] The radiator 800 is a cooling fan. When the cooling fan is running, since the heat dissipation cover 900 is provided on the radiator 800, the gas inhaled by the fan can be more concentrated, thereby increasing the speed and pressure of the gas, and ultimately increasing the wind force output by the cooling fan. The heat dissipation cover 900 can also improve operational safety. The use of the heat dissipation cover 900 can prevent the fan blades from coming into contact with other equipment or personnel, effectively reducing the possibility of injury to personnel. In addition, the cover can also prevent foreign objects from entering the fan, reducing the wear of the fan blades, and can effectively extend the service life of the cooling fan. Similarly, the first heat exchanger 300 is a condenser, and the condenser has a condensing fan. When the condenser is working, since the heat dissipation cover 900 is provided on the condenser, it can also increase the efficiency of the condensing fan, improve operational safety, and extend the service life of the condensing fan.

[0056] Since the radiator 800 is disposed between the compressor 200 and the first heat exchanger 300, i.e., the compressor 200 and the first heat exchanger 300 are relatively close, a single heat dissipation cover 900 can be used to cover both the radiator 800 and the first heat exchanger 300. Of course, in other embodiments, a separate heat dissipation cover 900 may be provided for each of the radiator 800 and the first heat exchanger 300, and this is not limited thereto.

[0057] In some embodiments, see Figure 3 and Figure 4The shell 100 includes a water receiving tray 140 and a main body 130. The water receiving tray 140 is connected to the main body 130 to form a circulating air duct. The second heat exchanger 400 is installed on the water receiving tray 140 or the main body 130. The compressor 200 and the first heat exchanger 300 are installed on the main body 130.

[0058] The refrigeration module 10 and the cabinet 20 are connected by a circulating air duct to realize the circulation of air. The refrigeration cavity 110, the air outlet 111 and the air inlet 112 are all located in the circulating air duct. Therefore, the cold air in the refrigeration cavity 110 can circulate between the refrigeration cavity 110 and the cabinet 20 of the electrical device 1 through the air outlet 111 and the air inlet 112 to realize the cooling of the cabinet 20 of the electrical device 1. The cold air in the refrigeration cavity 110 will form condensed water when heated. Therefore, a water receiving tray 140 needs to be set to collect the condensed water to reduce the condensed water entering the cabinet 20 and reduce the impact of the condensed water on the cabinet 20.

[0059] The second heat exchanger 400 can be mounted on the water receiving pan 140 or on the main body 130, without limitation. Of course, the compressor 200 and the first heat exchanger 300 are mounted on the side of the main body 130 facing away from the refrigeration chamber 110, so that the compressor 200 and the first heat exchanger 300 are located outside the refrigeration chamber 110, thereby reducing the amount of heat dissipated from the compressor 200 into the refrigeration chamber 110.

[0060] Specifically, a first inlet 131 and a first outlet 132 are provided on both sides of the main body 130, and a second inlet 141 and a second outlet 142 are provided on both sides of the water receiving tray 140. The main body 130 is installed in the water receiving tray 140 so that the first inlet 131 overlaps with the second inlet 141 to form an air inlet 112, and the first outlet 132 overlaps with the second outlet 142 to form an air outlet 111. A refrigeration cavity 110 is also formed between the water receiving tray 140 and the main body 130. The refrigeration cavity 110 is located between the air inlet 112 and the air outlet 111, and the insulation layer 700 is arranged between the mounting plate 600 and the main body 130.

[0061] In some embodiments, see Figure 2 and Figure 3 The housing 100 further includes a return air cover 150 , and the refrigeration module 10 further includes a return air fan 1000 . The return air cover 150 is provided to cover the return air fan 1000 .

[0062] Since the cold air in the refrigeration chamber 110 flows into the housing 20 of the electrical device 1 through the air outlet 111, after cooling the housing 20 of the electrical device 1, the heated air then flows into the refrigeration chamber 110 through the air inlet 112. After being cooled by the refrigeration module 10 to form cold air, it then flows into the housing 20 of the electrical device 1 through the air outlet 111, and the cycle repeats to achieve continuous cooling of the housing 20. Therefore, accelerating the flow of cold air can make the circulation speed of cold air faster, thereby improving the cooling efficiency. Since the refrigeration module 10 includes a return air fan 1000, the rotation of the return air fan 1000 can accelerate the speed at which air flows into the refrigeration chamber 110 through the air inlet 112, thereby accelerating the circulation speed of cold air and improving the cooling efficiency. In order to protect the return air fan 1000 and increase the operating efficiency of the return air fan 1000, the housing 100 also includes a return air hood 150, which is provided to cover the return air fan 1000.

[0063] Specifically, the return air hood 150 can be made of a material with good air permeability, such as foam, and the return air hood 150 can be a split structure or an integrated structure, which is not limited.

[0064] In some embodiments, the housing 100 further includes a circulating air hood 160 , and the refrigeration module 10 further includes a circulating fan 1100 . The circulating air hood 160 is disposed to cover the circulating fan 1100 .

[0065] Similarly, since the cooling module 10 includes a circulation fan 1100, the rotation of the circulation fan 1100 accelerates the flow of cold air through the air outlet 111 into the housing 20, thereby accelerating the circulation of the cold air and improving cooling efficiency. To protect the circulation fan 1100 and increase its operating efficiency, the housing 100 also includes a circulation hood 160, which is disposed over the circulation fan 1100.

[0066] Specifically, the circulating air hood 160 can be made of a material with good air permeability, such as foam, and the circulating air hood 160 can be a split structure or an integrated structure, which is not limited.

[0067] In some embodiments, the refrigeration module 10 further includes a return air fan 1000 , which is disposed between the air inlet 112 and the second heat exchanger 400 .

[0068] Since the rotation of the return air fan 1000 can speed up the flow of air into the refrigeration chamber 110 through the air inlet 112, the closer the return air fan 1000 is to the air inlet 112, the faster the air flows at the air inlet 112, and thus the faster the air flows into the refrigeration chamber 110 through the air inlet 112. Moreover, since the second heat exchanger 400 cools the refrigeration chamber 110, that is, the closer the position in the refrigeration chamber 110 is to the second heat exchanger 400, the lower the temperature. Therefore, the return air fan 1000 is arranged near the second heat exchanger 400, which can draw a large amount of air to the vicinity of the second heat exchanger 400, thereby improving the cooling efficiency of the air. The return air fan 1000 is arranged between the air inlet 112 and the second heat exchanger 400, that is, the return air fan 1000 is arranged near both the air inlet 112 and the second heat exchanger 400, thereby increasing the return air speed and the cooling efficiency of the return air in the refrigeration chamber 110, thereby improving the cooling efficiency of the cabinet 20.

[0069] In some embodiments, the refrigeration module 10 further includes a circulation fan 1100 , which is disposed between the air outlet 111 and the second heat exchanger 400 .

[0070] Similarly, since the rotation of the circulation fan 1100 can speed up the speed at which air flows into the cabinet 20 through the air outlet 111, the closer the circulation fan 1100 is to the air outlet 111, the faster the air flows at the air outlet 111, and thus the faster the air flows into the cabinet 20 through the air outlet 111. Moreover, since the second heat exchanger 400 cools the refrigeration chamber 110, that is, the closer the position in the refrigeration chamber 110 is to the second heat exchanger 400, the lower the temperature. Therefore, the circulation fan 1100 is arranged close to the second heat exchanger 400, and a large amount of cold air near the second heat exchanger 400 can be introduced into the cabinet 20, thereby improving the cooling effect on the cabinet 20. The circulation fan 1100 is arranged between the air outlet 111 and the second heat exchanger 400, that is, the circulation fan 1100 is arranged close to both the air outlet 111 and the second heat exchanger 400, thereby increasing the circulation speed of the air and improving the cooling effect on the cabinet 20.

[0071] Based on the same inventive concept, please refer to Figure 5 and Figure 6 The present embodiment further provides an electrical device 1 comprising a housing 20 and the aforementioned refrigeration module 10. The refrigeration module 10 is connected to the housing 20, i.e., the refrigeration module 10 is mounted on the housing 20, allowing the refrigeration module 10 to cool the housing 20. The beneficial effects of the electrical device 1 provided in the present embodiment are the same as those of the refrigeration module 10 described above and are not further described here. The electrical device 1 may be a refrigerator, an air conditioner, a cold drink dispenser, etc., without limitation.

[0072] In some embodiments, the refrigeration module 10 may be disposed outside the box 20 .

[0073] In order to save space in the housing 20, the refrigeration module 10 can be installed outside the housing 20. Of course, in order to connect the housing 20 with the refrigeration cavity 110, a passage must be provided on the housing 20. Specifically, a vent 21 can be provided on the housing 20 to connect the housing 20 with the refrigeration cavity 110, or a ventilation slot 22 can be provided on the housing 20, and the refrigeration module 10 can be installed in the ventilation slot 22, so that the housing 20 is connected to the refrigeration cavity 110 through the ventilation slot 22.

[0074] Of course, in other embodiments, the refrigeration module 10 may also be disposed in the box body 20 , which is not limited thereto.

[0075] In some embodiments, the refrigeration module 10 is disposed on the top or bottom of the box 20 .

[0076] See also Figure 5 The electrical device 1 may include an installation cabinet 1200, in which the refrigeration module 10 is installed. In this way, the installation cabinet 1200 can be installed at the bottom of the cabinet 20 to bear the weight of the cabinet 20, allowing the refrigeration module 10 to be installed at the bottom of the cabinet 20. Of course, both the installation cabinet 1200 and the cabinet 20 need to have ventilation holes 21 to allow the cabinet 20 to communicate with the refrigeration chamber 110.

[0077] See also Figure 6 When the refrigeration module 10 is set on the top of the box body 20, a ventilation slot 22 can be directly opened on the top of the box body 20, and the refrigeration module 10 can be installed in the ventilation slot 22. The box body 20 can be connected to the refrigeration cavity 110 through the ventilation slot 22.
