[0055] The refrigeration device in the present application generally comprises a box body, a door body and a refrigeration system, wherein at least a refrigeration compartment is formed in the box body, and the refrigeration compartment is opened and closed through the door body to meet the requirements of storing and retrieving articles.

[0056] The refrigeration system uses a compressor, condenser, expansion valve and evaporator to perform the refrigeration cycle of the refrigeration equipment. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to achieve cooling of the items in the box.

[0057] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0058] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can cool the items in the box by utilizing the latent heat of evaporation of the refrigerant.

[0059] refer to Figure 1 , Figure 2 The present application proposes a refrigeration device, which includes a box body 100 and a refrigeration system arranged in the box body 100.

[0060] The box body 100 includes an outer shell and an inner shell. The inner shell is arranged on the inner side of the outer shell. A refrigeration chamber is formed in the inner shell. The refrigeration chamber includes a refrigerating chamber 101 and a freezing chamber 102 .

[0061] A food introduction port is provided at the front end of the refrigeration chamber for taking in and putting in food, and a door body 110 is hingedly connected to one side of the refrigeration chamber for controlling the opening and closing of the refrigeration chamber.

[0062] An equipment chamber 103 is also formed between the outer shell and the inner tank, and the equipment chamber 103 is used to place refrigeration-related equipment.

[0063] The equipment chamber 103 involved in the present application is arranged below the inner container. Of course, the equipment chamber 103 can also be arranged at other positions outside the inner container.

[0064] The refrigeration system includes a compressor, a condenser 200 and an evaporator connected by a refrigeration pipeline, the output end of the compressor is connected to the condenser 200, the condenser 200 is connected to the evaporator, and the output end of the evaporator is connected to the compressor.

[0065] The compressor and the condenser 200 are arranged in the equipment chamber 103, and the evaporator is attached to the outer wall of the inner tank away from the refrigeration chamber.

[0066] The low temperature generated during the heat exchange process of the evaporator passes through the rear wall of the inner tank and is transferred to the refrigeration cavity to keep the food fresh.

[0067] refer to Figure 4 , Figure 5 A fan component 300 is disposed on one side of the condenser 200 , and the condenser 200 includes at least four heat exchange surfaces formed by the heat exchange tubes 210 , and each heat exchange surface is respectively arranged around the circumference of the fan component 300 .

[0068] Specifically, an air inlet and an air outlet are formed on the fan component 300. After the fan component 300 is turned on, driven by the fan blades, air flow is input from the air inlet of the fan component 300 and output from the air outlet.

[0069] refer to Figure 7 The heat exchange surface of the condenser 200 includes a top heat exchange surface 211 , a front heat exchange surface 212 and two side heat exchange surfaces 213 which are respectively arranged around the top, the air outlet and the side of the fan member 300 .

[0070] The top heat exchange surface 211 , the side heat exchange surface 213 and the front heat exchange surface 212 are specifically formed by winding a heat exchange tube 210 .

[0071] Furthermore, in some embodiments of the present application, the top heat exchange surface 211 , the front heat exchange surface 212 , and the two side heat exchange surfaces 213 respectively include at least one layer of heat exchange tubes 210 .

[0072] In other words, the top heat exchange surface 211, the front heat exchange surface 212 and the two side heat exchange surfaces 213 can be provided with two or more layers of heat exchange tubes 210 along the flow direction of the airflow to further improve the heat exchange efficiency.

[0073] refer to Figure 8-Figure 10 For the convenience of processing, the top heat exchange surface 211, the front heat exchange surface 212 and the two side heat exchange surfaces 213 are formed by bending the condensation body 2101.

[0074] Specifically, take the example that the top heat exchange surface 211 , the front heat exchange surface 212 , and the two side heat exchange surfaces 213 are all a layer of heat exchange tubes 210 .

[0075] The heat exchange tubes 210 are reciprocatingly arranged in a plane to form a condensation body 2101 . After the condensation body 2101 is formed, it is bent to form a top heat exchange surface 211 and a side heat exchange surface 213 that are perpendicular to the front heat exchange surface 212 .

[0076] The width of the corresponding position of the top heat exchange surface 211 on the condensing body 2101 is consistent with the width of the front heat exchange surface 212, and the two side heat exchange surfaces 213 are respectively located on both sides of the front heat exchange surface 212. During processing, the front heat exchange surface 212 of the condensing body 2101 is bent to be perpendicular to the front heat exchange surface 212, and the two side heat exchange surfaces 213 are consistent with the bending direction of the front heat exchange surface 212.

[0077] A wind cavity structure with openings at the lower end and the rear end is formed in the condenser 200. During installation, the lower end of the condenser 200 is fixed to the bottom of the equipment chamber 103, and the fan component 300 is installed into the wind cavity from the rear end, and the air outlet end of the fan component 300 is arranged opposite to the front heat exchange surface 212.

[0078] ,refer to Figure 6 In the refrigeration equipment involved in the present application, the condenser 200 includes at least four heat exchange surfaces formed by the heat exchange tubes 210, and each heat exchange surface is respectively arranged around the fan part 300. Then, the airflow around the fan part 300 can pass through the corresponding heat exchange surface respectively, and the heat exchange area is greatly improved, so that the incoming air and part of the outlet air of the condensing fan motor are fully utilized to improve the heat exchange efficiency; and the condenser 200 surrounding the fan part 300 can also block foreign matter and prevent the fan part 300 from getting stuck.

[0079] refer to Fig. 9 In some embodiments of the present application, in order to improve the heat dissipation effect of the heat exchange tubes 210 , heat dissipation wires 220 are arranged between the heat exchange tubes 210 , and the extension direction of the heat dissipation wires 220 is arranged at an angle to the heat exchange tubes 210 .

[0080] The heat sink wire 220 is wound around the outside of the heat exchange tube 210 in an "8" shape in a direction perpendicular to the axis of the heat exchange tube 210 , which not only improves the heat dissipation effect of the heat exchange tube 210 , but also provides a connection function for the heat exchange tube 210 .

[0081] Reference again Figure 4 , Figure 6 A positioning portion 214 is formed on the top heat exchange surface 211 , and the water receiving tray 400 is installed on the top heat exchange surface 211 through the positioning portion 214 .

[0082] A water receiving tray 400 can also be placed directly above the top heat exchange surface 211. The condenser 200 also serves as a supporting structure for the water receiving tray 400. The lower temperature condensed water in the water receiving tray 400 is used to lower the temperature of the condenser 200. At the same time, the high temperature of the condenser 200 is used to increase the evaporation efficiency of the condensed water in the water receiving tray 400, which is more energy-efficient.

[0083] Specifically, the positioning portion 214 may be a positioning structure fixed on both sides of the top heat exchange surface 211 through a positioning bracket.

[0084] The water receiving tray 400 is restricted above the top heat exchange surface 211 by the positioning portions 214 on both sides.

[0085] Alternatively, the positioning portion 214 may be implemented by the following structure;

[0086] The bends 2111 corresponding to the heat exchange tubes 210 on the top heat exchange surface 211 are bent upward, and installation positions are formed between the bends 2111 on both sides. The water receiving tray 400 is installed in the installation position formed between the bends 2111 .

[0087] The surrounding structure of the condenser 200 for the fan component 300 can ensure that the surrounding air intake of the fan component 300 passes through the corresponding heat exchange surfaces. Specifically, the airflow input from the two sides of the fan component 300 passes through the two side heat exchange surfaces 213, the airflow entering from the top of the fan component 300 passes through its top heat exchange surface 211, and the airflow output from the fan component 300 passes through the front heat exchange surface 212 again for heat exchange, so that the air intake from all directions passes through the condenser 200, and the exhaust airflow also passes through the condenser 200, thereby improving the enhanced heat exchange efficiency of the condenser 200.

[0088] Secondly, the top heat exchange surface 211 can also serve as a supporting structure for the water receiving tray 400 , and the return bends 2111 on both sides are appropriately bent upward to facilitate the installation and removal of the water receiving tray 400 .

[0089] This solution uses the high-temperature condenser 200 and the low-temperature water receiving tray 400 to perform heat exchange on the condensed water, thereby reducing the condensation temperature of the system and accelerating the self-evaporation of the condensed water.

[0090] Reference again Figure 4-Figure 6 In some embodiments of the present application, a mounting base 120 is formed at the bottom of the equipment chamber 103 , and the compressor, the fan component 300 and the condenser 200 are all fixed on the mounting base 120 .

[0091] The fan component 300 is fixed on the mounting base 120 via a fan bracket 310 .

[0092] The fan support 310 includes at least two fan vertical frames 312 arranged at intervals and a fan horizontal frame 311 connected to the top of the fan vertical frames 312 , and the fan component 300 is fixed on the fan horizontal frame 311 .

[0093] A connecting leg 313 is also formed at the bottom of the fan stand 312 , and the fan stand 312 is fixed to the mounting base 120 via the connecting leg 313 .

[0094] The fan stand 312 , the fan cross frame 311 and the connecting legs 313 can be integrally formed by bending a plate.

[0095] Alternatively, they may be processed separately and then connected into one piece by welding or mechanical connection such as fasteners.

[0096] Combination Figure 6 , Figure 7 The bottoms of the two side heat exchange surfaces 213 of the condenser 200 are fixed on the mounting base 120 through the heat dissipation bracket 230 .

[0097] The heat dissipation bracket 230 includes a heat exchange vertical plate 231 fixed on the heat exchange wire and a fixed bottom plate 232 formed at the bottom of the heat exchange vertical plate 231 . The fixed bottom plate 232 is perpendicular to the heat exchange vertical plate 231 .

[0098] Similarly, the fixed bottom plate 232 and the heat exchange vertical plate 231 can be formed by bending the plate as a whole, or can be processed separately and then welded or mechanically connected together.

[0099] On the other hand, the present application also proposes a refrigeration device, which includes a box body 100 and a refrigeration system arranged in the box body 100.

[0100] The box body 100 includes an outer shell and an inner shell. The inner shell is arranged on the inner side of the outer shell. A refrigeration chamber is formed in the inner shell. A door body 110 is hinged on one side of the refrigeration chamber for controlling the opening and closing of the refrigeration chamber.

[0101] An equipment chamber 103 is also formed between the outer shell and the inner tank, and the equipment chamber 103 is used to place refrigeration-related equipment.

[0102] The equipment chamber 103 involved in the present application is arranged below the inner tank, and the refrigeration system includes a compressor, a condenser 200 and an evaporator connected by refrigeration pipelines.

[0103] The compressor and the condenser 200 are arranged in the equipment chamber 103, and the evaporator is attached to the outer wall of the inner tank away from the refrigeration chamber.

[0104] A fan component 300 is disposed on one side of the condenser 200. The condenser 200 is formed by winding a heat exchange tube 210. The condenser 200 is configured to be surrounded by the fan component 300 to increase the heat exchange area of ​​the condenser 200 and improve the heat exchange efficiency.

[0105] The specific enclosing form of the condenser 200 can be realized by the following methods:

[0106] Method 1:

[0107] In some embodiments of the present application, the condenser 200 includes a heat exchange tube 210 and a heat dissipation frame, and the heat dissipation frame is formed by a steel wire structure. In order to improve the structural stability of the heat dissipation frame, supporting ribs are also arranged in the heat dissipation frame so that the heat dissipation frame forms a stable frame-shaped support structure.

[0108] The bottom of the heat dissipation frame is fixed in the equipment chamber 103, and the heat exchange tubes 210 are arranged reciprocatingly on the outer wall of the heat dissipation frame.

[0109] The heat generated by the heat exchange tube 210 during the heat exchange process is dissipated to the surroundings through the heat dissipation frame.

[0110] The heat dissipation frame specifically includes a front supporting surface, a top supporting surface and a side supporting surface. The top supporting surface is located above the front supporting surface, the side supporting surfaces are located on both sides of the front supporting surface, and the top of the side supporting surface is connected to the top supporting surface.

[0111] That is, the heat dissipation frame is a frame structure with an opening on one side, and the fan component 300 is fixed in the wind cavity formed by the heat dissipation frame. The air inlet end of the fan component 300 faces the open side of the heat dissipation frame, and the air outlet end of the fan component 300 faces the front support surface of the heat dissipation frame.

[0112] This is beneficial to improving the heat exchange efficiency of the condenser 200, and the airflow formed by the fan component 300 can exchange heat with the heat exchange tube 210 more, thereby improving the heat exchange efficiency.

[0113] The surrounding structure of the condenser 200 can play a protective role and can replace the air duct baffle used outside the condenser 200 to prevent the fan motor from sucking in foreign objects such as plastic bags to generate noise or jam the fan blades, while preventing air from forming vortices in the air duct baffle.

[0114] Method 2:

[0115] refer to Figure 4-Figure 6 In other embodiments, the condenser 200 includes at least four heat exchange surfaces formed by the heat exchange tubes 210 , and each heat exchange surface is respectively arranged around the circumference of the fan component 300 .

[0116] Specifically, an air inlet and an air outlet are formed on the fan component 300. After the fan component 300 is turned on, driven by the fan blades, air flow is input from the air inlet of the fan component 300 and output from the air outlet.

[0117] The heat exchange surface of the condenser 200 includes a top heat exchange surface 211 , a front heat exchange surface 212 and two side heat exchange surfaces 213 which are respectively arranged around the top end, the air outlet end and the side of the fan component 300 .

[0118] The top heat exchange surface 211 , the side heat exchange surface 213 and the front heat exchange surface 212 are specifically formed by winding a heat exchange tube 210 .

[0119] Furthermore, in some embodiments of the present application, the top heat exchange surface 211 , the front heat exchange surface 212 , and the two side heat exchange surfaces 213 respectively include at least one layer of heat exchange tubes 210 .

[0120] In order to improve the heat dissipation effect of the heat exchange tubes 210 , heat dissipation wires 220 are arranged between the heat exchange tubes 210 , and the extending direction of the heat dissipation wires 220 is arranged at an angle to the heat exchange tubes 210 .

[0121] The heat sink wire 220 is wound around the outside of the heat exchange tube 210 in an "8" shape in a direction perpendicular to the axis of the heat exchange tube 210 , which not only improves the heat dissipation effect of the heat exchange tube 210 , but also provides a connection function for the heat exchange tube 210 .

[0122] Method 3:

[0123] In some embodiments of the present application, a positioning portion 214 is further formed on the top supporting surface of the heat dissipation frame.

[0124] The water receiving tray 400 is installed on the top supporting surface through the positioning portion 214 and is located above the heat exchange tubes 210 arranged on the top supporting surface.

[0125] The condenser 200 also serves as a supporting structure for the water tray 400, using the lower temperature condensed water in the water tray 400 to lower the temperature of the condenser 200, while using the high temperature of the condenser 200 to increase the evaporation efficiency of the condensed water in the water tray 400, which is more energy-efficient.

[0126] Alternatively, the positioning portion 214 may be implemented by the following structure.

[0127] The bends 2111 corresponding to the heat exchange tubes 210 on the top heat exchange surface 211 are bent upward, and installation positions are formed between the bends 2111 on both sides. The water receiving tray 400 is installed in the installation position formed between the bends 2111 .

[0128] The surrounding structure of the condenser 200 for the fan component 300 can ensure that the surrounding air intake of the fan component 300 passes through the corresponding heat exchange surfaces. Specifically, the airflow input from the two sides of the fan component 300 passes through the two side heat exchange surfaces 213, the airflow entering from the top of the fan component 300 passes through its top heat exchange surface 211, and the airflow output from the fan component 300 passes through the front heat exchange surface 212 again for heat exchange, so that the air intake from all directions passes through the condenser 200, and the exhaust airflow also passes through the condenser 200, thereby improving the enhanced heat exchange efficiency of the condenser 200.

[0129] Secondly, the top heat exchange surface 211 can also serve as a supporting structure for the water receiving tray 400 , and the return bends 2111 on both sides are appropriately bent upward to facilitate the installation and removal of the water receiving tray 400 .

[0130] This solution uses the high-temperature condenser 200 and the low-temperature water receiving tray 400 to perform heat exchange on the condensed water, thereby reducing the condensation temperature of the system and accelerating the self-evaporation of the condensed water.

[0131] The above three methods can be used in combination of method one and method three, or in combination of method two and method three.

[0132] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.
