Description

Technical Field

[0001] The utility model relates to the technical field of ice making machines, in particular to an ice making machine having a refrigeration equipment structure of the ice making machine. Background Art

[0002] As for refrigeration equipment, such as the automatic ice maker equipped in the refrigerator, it can be divided into direct cooling ice maker and air cooling ice maker according to the refrigeration method.

[0003] The direct cooling ice maker is equipped with an ice-making evaporator tube under the metal ice tray. The ice-making evaporator tube is installed under the ice tray. Since the temperature of the ice-making evaporator tube is lower (generally below -25°C, lower than the supply air temperature) and it is in close contact with the ice tray on the ice maker, the heat exchange resistance is small, so it has the characteristics of high heat exchange efficiency and fast ice making speed.

[0004] Although the temperature of the ice-making evaporator pipe is very low and it is in contact with the ice-making grid for heat conduction, only the upper part of the ice-making evaporator pipe is in contact with the ice-making grid, and the contact pipe is short and the contact area is small, which seriously restricts the ice-making speed of the refrigeration ice-making machine.

[0005] Moreover, its heat exchange effect is affected by the installation process. If the evaporator tube and the ice cube tray are not tightly installed, or the evaporator tube has been deformed before installation, local interference and loose contact with the ice maker will greatly reduce the heat exchange efficiency of the ice maker.

[0006] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

The heat exchange path of the refrigerant is shorter, the heat exchange loss is smaller, and the heat exchange speed is faster.

[0050] Since the refrigerant microchannel is directly formed inside the main component of the ice cube tray, during heat exchange, the refrigerant in the main component of the ice cube tray can directly exchange heat with water, eliminating the contact thermal resistance between the original ice-making evaporator pipe and the ice cube tray, and the heat exchange thermal resistance is smaller, reducing the heat exchange thermal resistance of the refrigerant and improving the heat exchange efficiency;

[0051] Furthermore, since the ice-making evaporator pipe is omitted, the clamping assembly of the ice-making evaporator pipe and the ice-making tray and the assembly and connection steps between the ice-making evaporator pipe and the foaming layer of the refrigeration device box are also omitted, thereby simplifying the structure of the entire ice-making machine and improving the assembly efficiency of the entire ice-making machine.

[0052] In addition, multiple refrigerant microchannels are arranged in the main component of the ice cube tray. During heat exchange, heat can be exchanged with water at the same time through multiple refrigerant microchannels. The heat exchange area is greatly increased from the original one ice-making evaporator tube to distributed heat exchange of multiple refrigerant microchannels, which increases the heat exchange area and thus improves the heat exchange efficiency.

[0073] The utility model provides an embodiment of an ice making machine, comprising:

[0074] An ice making tray, wherein a plurality of ice storage trays 120 are formed inside;

[0075] In some embodiments of the present application, the ice making tray is made of metal, and a partition member 600 is disposed inside the ice making tray to separate the ice making tray into a plurality of ice storage trays 120 for storing ice. The ice making tray is used to freeze the water stored therein into ice cubes.

[0076] The ice making grid is provided with a water injection port, which can be used to inject water into the ice making grid to make ice.

[0077] The ice blocking grid 150 is arranged at the top of the ice making grid to block the ice cubes in the ice making grid to prevent them from falling.

[0078] The ice blocking grid 150 includes a plurality of ice blocking protrusions connected to the ice making grid and arranged in parallel in sequence along the length direction of the ice making grid.

[0079] An ice scraper rod 200 is rotatably mounted on the ice tray and is used to scrape ice cubes out of the ice tray;

[0080] An ice scraper rod 200 is installed on the ice making tray. The ice scraper rod 200 is provided with an ice hanging protrusion. The ice scraper rod 200 is rotatably installed at the top position of the ice making tray and is used to scrape ice cubes in the ice making tray.

[0081] In order to heat the ice cubes in the ice making tray, an ice scraping heating pipe 720 is provided around the bottom of the ice making tray and is arranged circumferentially around the ice making tray.

[0082] In order to realize the installation of the ice scraping heating pipe 720, a heating pipe installation groove 710 is set around the ice making grid, and the ice scraping heating pipe 720 is assembled in the heating pipe installation groove 710. After the ice cubes in the ice making grid are formed, they can be heated for a short time by the ice scraping heating pipe 720 and then scraped out by the ice scraping rod 200.

[0083] An ice storage box 900 is arranged below the ice making tray and is used to receive ice cubes that fall out of the ice making tray;

[0084] An ice pusher is arranged in the ice storage box and is used to push the ice cubes in the ice storage box outwards;

[0085] The ice pushing member may be an ice pushing screw, which can push the ice cubes outwards when the screw rotates.

[0086] An ice-discharging motor is connected to the ice-pushing member and is used to drive the ice-pushing member to move;

[0087] In order to store the scraped ice cubes, an ice storage box 900 is provided below the ice making grid, wherein an ice dispensing motor and an ice pusher are provided inside the ice storage box, and the ice cubes entering the ice storage box are pushed outward by the ice dispensing motor driving the ice pusher.

[0088] In the initial state, water is added to the ice cube tray, which needs to absorb cold energy to turn into ice cubes.

[0089] After the water in the ice storage grid 120 turns into ice cubes, the ice cubes inside can be briefly heated by the ice scraping heating tube 720 to separate them from the ice storage grid 120. Then, the ice scraping rod 200 is moved to scrape the ice cubes outward and drop them into the ice storage box 900 located below it. The ice discharging motor in the ice storage box 900 rotates to drive the ice pushing member connected thereto to rotate, and the ice cubes in the ice storage box 900 are delivered.

[0090] In some embodiments of the present application, the ice tray includes:

[0091] The ice cube tray main body component 100 has openings formed at both ends and the top;

[0092] The refrigerant microchannels 110 are formed inside the ice cube main body 100 and are provided in plurality for connecting to the refrigeration system of a refrigeration device to transfer the cooling capacity of the refrigeration system to the ice cube to cool the water inside the ice cube.

[0093] The ice tray main body component 100 is a main component constituting the ice tray, which can be formed by bending. After bending, the ice tray main body component 100 forms the bottom surface and two oppositely arranged side surfaces of the ice tray, and openings are formed on the top and both ends.

[0094] In some embodiments of the present application, the ice cube main body component can be directly formed by stamping and bending a metal microchannel radiator. A large number of refrigerant microchannels 110 are distributed inside the metal microchannel radiator to facilitate the flow of refrigerant therethrough. When the refrigerant flows through the refrigerant microchannels 110 of the ice cube main body component 100, the cold energy of the refrigerant can be transferred to the heat exchange surface of the ice cube main body component 100 that contacts water, and then transferred to the water flow in the ice cube.

[0095] The end blocking components 300 are used to block the openings at both ends of the ice cube main body component 100 to form an ice cube with an open top together with the ice cube main body component 100;

[0096] When fixing, the end stopper components 300 can be welded and fixed at the opening positions at both ends of the ice cube main body component 100 to block both ends of the ice cube main body component 100 .

[0097] In some embodiments of the present application, the end stopper component 300 includes a first end stopper, which blocks an opening at one end of the ice cube main body component 100 and is fully welded and fixed to the ice cube main body component 100;

[0098] The first end stop member 300 is a first end stop plate, which is vertically arranged on the ice cube main body component 100, attached to the end surface of one end of the ice cube main body component 100 and blocks the opening of one end.

[0099] The second end stopper blocks the other end opening of the ice cube main body component 100 and is fully welded and fixed to the ice cube main body component 100 .

[0100] The second end stopper is a second end stopper plate, which is vertically arranged on the ice cube main body component 100, and is attached to the end surface of the other end of the ice cube main body component 100 to block the opening of the other end.

[0101] After the ice cube main body 100 is formed, the punched first end stopper and the second end stopper are welded and fixed to the ice cube main body 100. The first end stopper and the second end stopper should include a mounting hole for the ice scraper rod 200.

[0102] The first end stopper and the second end stopper should be fully welded to ensure that the ice tray will not leak.

[0103] The main body component 100 of the ice cube tray is formed by a metal microchannel heat exchanger and the end stop components 300 at the front and rear positions are welded to greatly increase the heat exchange area between the refrigeration system and the water or ice in the ice cube tray;

[0104] The water added to the ice making trays will be located in the plurality of ice storage trays 120 , and the water will mainly contact the bottom surface and the side surface formed by the ice tray main body member 100 .

[0105] By disposing a plurality of refrigerant microchannels 110 inside the ice cube main body component 100 , the refrigerant can flow into the ice cube main body component 100 to directly exchange heat with the water or ice inside the ice cube main body component 100 .

[0106] The refrigerant microchannel 110 of the ice cube main body component 100 is connected to the refrigerant pipeline of the refrigeration system. When the ice maker is making ice, the refrigerant of the refrigerant system will flow into each refrigerant microchannel 110, and exchange heat with the water or ice in the ice cube main body component 100 after passing through the ice cube main body component 100. The heat exchange path of the refrigerant is changed from the existing ice making evaporation pipe to the ice cube to water to the ice cube main body component 100 to water. The heat exchange path of the refrigerant is shorter, the heat exchange loss is smaller, and the heat exchange speed is faster.

[0107] The refrigerant in the ice tray main body component 100 directly exchanges heat with water, thereby eliminating the contact thermal resistance between the original ice-making evaporation pipe and the ice tray, and the heat exchange thermal resistance is smaller, thereby reducing the heat exchange thermal resistance of the refrigerant and improving the heat exchange efficiency;

[0108] In addition, a plurality of refrigerant microchannels 110 are arranged in the ice cube main body component 100. During heat exchange, heat can be exchanged with water simultaneously through the plurality of refrigerant microchannels 110. The heat exchange area is greatly increased from the original one ice-making evaporating tube to a distributed plurality of refrigerant microchannels 110, thereby increasing the heat exchange area and improving the heat exchange efficiency.

[0109] In addition, according to the heat transfer calculation formula, the heat exchange amount Q=KF△t, the heat transfer thermal resistance is small, the heat transfer coefficient K is higher, and the heat exchange area F is larger. Therefore, under the same heat exchange temperature difference △t conditions, the heat transfer amount is greater, the ice making speed is faster, and the ice making efficiency is improved.

[0110] Finally, since the refrigerant microchannel 110 is directly formed through the ice cube main body component 100 for heat exchange, the ice-making evaporator tube structure of the direct cooling ice-making machine is eliminated, and the clamping assembly between the ice-making evaporator tube and the ice cube, and the installation steps between the ice-making evaporator tube and the foaming layer of the box body 800 are omitted, thereby simplifying the structure of the entire ice-making machine and improving the assembly efficiency of the entire ice-making machine.

[0111] The ice-making evaporator used for heat exchange is integrated with the ice-making tray. The ice-making tray serves as a heat exchanger, thereby eliminating the need for a separate ice-making tray and the heat transfer resistance of the ice-making tray as an intermediate component. The cold energy of the refrigeration system is directly transferred to the water through the refrigerant microchannels 110, and the water is frozen into ice. The dense refrigerant microchannels 110 are evenly distributed on the entire ice-making surface of the ice tray main component 100, thereby greatly increasing the heat exchange area.

[0112] In some embodiments of the present application, the ice making machine further comprises:

[0113] The inlet header component 400 is respectively connected to the refrigerant pipeline of the refrigeration system and the inlets of the plurality of refrigerant microchannels 110, and is used to transfer the refrigerant of the refrigeration system to the plurality of refrigerant microchannels 110;

[0114] The outlet manifold component 500 is respectively connected to the refrigerant pipeline of the refrigeration system and the outlets of the plurality of refrigerant microchannels 110 to transport the refrigerant after heat exchange back to the refrigeration system.

[0115] In order to realize the connection between the refrigeration of the ice cube tray and the refrigeration system of the refrigerator, headers are welded on both sides of the ice cube tray, namely the inlet header component 400 and the outlet header component 500. After the refrigerant of the refrigeration system flows out, it will first enter the inlet header component 400, and then be diverted to each refrigerant microchannel 110 through the inlet header component 400. After the refrigerant flows through each refrigerant microchannel 110 and the ice flows through the ice cube tray, it is gathered at the outlet header component 500 at the outlet, and then flows back to the compressor of the refrigeration equipment.

[0116] When the refrigerant flows through the multiple refrigerant microchannels 110 in the ice cube main body component 100, it exchanges heat with the water in the ice cube, absorbs heat and cools the water in the ice cube into ice cubes, and realizes rapid heat exchange through the multiple refrigerant microchannels 110 to achieve a rapid ice-making effect.

[0117] In some embodiments of the present application, the plurality of refrigerant microchannels 110 are sequentially arranged side by side along the length direction of the ice cube main body component 100;

[0118] Alternatively, they are arranged side by side in sequence along the width direction of the ice cube tray main body component 100 .

[0119] That is, during arrangement, the refrigerant microchannels 110 can be arranged along the length direction of the ice cube main body component 100.

[0120] Alternatively, the refrigerant microchannels 110 may be arranged along the width direction of the ice cube main body component 100 , as long as the refrigerant microchannels 110 are arranged inside the ice cube main body component 100 and heat exchange is achieved through the refrigerant microchannels 110 .

[0121] In some embodiments of the present application, the ice cube main body component 100 is formed by bending, and includes:

[0122] Bottom member 130;

[0123] and side members 140 formed by bending from both sides of the bottom member 130;

[0124] The refrigerant microchannel 110 is sequentially arranged to penetrate the side member 140 on one side, the bottom member 130 and the side member 140 on the other side.

[0125] That is, when the refrigerant microchannel 110 is arranged, its arrangement direction is to extend from the side member 140 on one side to the bottom member 130, and then extend from the bottom member 130 to the side member 140 on the other side. The flowing refrigerant inside it flows in from the side member 140, then flows through the bottom member 130 at the bottom position, and then flows into the side member 140 at the other side position, and flows out from the side member 140 on the other side.

[0126] A plurality of refrigerant microchannels 110 are provided and arranged in parallel, and the plurality of refrigerant microchannels 110 flow through the side member 140 and the bottom member 130 on one side and the side member 140 on the other side respectively, so that the refrigerant flows evenly through all components of the ice cube main body member 100, ensuring that the heat exchange area of ​​the water inside is large enough and even, thereby ensuring the heat exchange effect.

[0127] In some embodiments of the present application, the ice cube main body component 100 is formed by bending, and includes:

[0128] Bottom member 130;

[0129] and side members 140 formed by bending from both sides of the bottom member 130;

[0130] A plurality of the refrigerant microchannels 110 are disposed through the bottom member 130;

[0131] Alternatively, a plurality of the refrigerant microchannels 110 are disposed through the side member 140;

[0132] Alternatively, part of the refrigerant microchannels 110 are disposed through the bottom member 130 , and part of the refrigerant microchannels 110 are disposed through the side member 140 .

[0133] When the refrigerant microchannel 110 is provided, it can be arranged only on the bottom member 130 constituting the main body of the ice cube tray, so as to perform heat exchange with the water located inside the bottom member 130 through the refrigerant microchannel 110 at the bottom member 130;

[0134] Alternatively, during the setting, the refrigerant microchannel 110 is arranged on the side member 140. When arranged, the refrigerant microchannel 110 can be arranged on both side members 140, or the refrigerant microchannel 110 can be arranged on only one of the side members 140. By arranging the refrigerant microchannel 110 on the side member, heat exchange can also be performed with the water inside the ice cube tray.

[0135] Alternatively, during the setting, part of the refrigerant microchannels 110 are set on the bottom member 130, evenly covering the bottom member 130, and part of the refrigerant microchannels 110 are set on the side member 140, evenly covering the side member 140, so that the refrigerant microchannels 110 are arranged on the bottom member 130 and the side member 140 of the ice cube main body member 100, and the refrigerant microchannels 110 can be extended along the length direction of the entire ice cube.

[0136] In some embodiments of the present application, the inner diameters of the plurality of refrigerant microchannels 110 gradually increase from a direction close to the inlet header component 400 to a direction away from the inlet header component 400;

[0137] The inner diameter of the refrigerant microchannel 110 is set to different micropore sizes so that it can adapt to refrigerant microchannels 110 of different lengths.

[0138] When the flow path corresponding to the refrigerant microchannel 110 is short, the inner diameter of the refrigerant microchannel 110 can be set to be smaller, so that the flow resistance encountered by the refrigerant when flowing inside the refrigerant microchannel 110 is larger;

[0139] When the flow path corresponding to the refrigerant microchannel 110 is long, the inner diameter of the refrigerant microchannel 110 can be set to be larger, so that the flow resistance encountered by the refrigerant when flowing inside the refrigerant microchannel 110 is smaller;

[0140] This allows the refrigerant to achieve resistance balance when flowing in the refrigerant microchannels 110 of different lengths, thereby avoiding temperature differences in the ice cube tray due to different heat exchange efficiencies.

[0141] Alternatively, the inner diameters of the plurality of refrigerant microchannels 110 remain unchanged from a direction close to the inlet header component 400 to a direction away from the inlet header component 400 .

[0142] If the channel path lengths of each refrigerant microchannel 110 are basically the same, in order to keep the circulation resistance of each refrigerant microchannel 110 basically the same, when setting, the inner diameters of multiple refrigerant microchannels 110 can be set to be the same, so that the flow resistance encountered by the refrigerant when flowing through each refrigerant microchannel 110 is also the same, so that the temperature difference of the entire ice making grid is small and the heat exchange efficiency is high.

[0143] In some embodiments of the present application, it also includes:

[0144] A plurality of partition members 600 are provided and vertically arranged in the ice tray main body member 100 to divide the ice making cavity into a plurality of ice storage spaces;

[0145] The partition member 600 is a partition plate, which is arranged vertically to the ice tray main body member 100 to partition the ice tray main body member 100. A gap should be left on the partition member 600 to ensure that after water is poured into the ice tray, the water can be evenly distributed in the entire ice tray.

[0146] In order to achieve a matching connection between the partition component 600 and the ice tray main body component and ensure that the bottom of the partition component 600 maintains good contact and fit with the bottom and side surfaces of the ice tray main body component 100, when setting, the shape of the partition component 600 is set to match the shape of the ice tray main body component 100, and is fully welded and fixed to the ice tray main body component 100, thereby ensuring the sealing and structural strength of the entire ice tray.

[0147] After the end stop parts 300 at both ends of the ice tray main component 100 are welded, the partition parts 600 of the ice tray are welded again to ensure that the shape of the ice tray meets the user's requirements.

[0148] The partition component 600 is welded to the ice cube main body component 100 and forms an integral structure with the ice cube main body component 100. The partition component 600 added to the ice cube main body component 100 is equivalent to adding a fin structure to the ice cube main body component 100 serving as a heat exchanger. The coldness of the refrigerant in the multiple refrigerant microchannels 110 of the ice cube main body component 100 can also be transferred to the partition component 600 welded and fixed to it. The partition component 600 also contacts the water arranged in the ice storage grid 120 at the same time, and then exchanges heat with the water in the ice storage grid 120, so that the heat exchange area of ​​the entire ice cube is increased from the bottom and side surfaces of the ice cube main body component 100 to the bottom and side surfaces of the ice cube main body component 100 and the side surfaces of the partition component 600, thereby further increasing the heat exchange area of ​​the entire ice cube and enhancing the heat exchange effect of the ice maker.

[0149] In some embodiments of the present application, a refrigeration device having a direct cooling ice maker is provided, comprising:

[0150] The box body 800 includes a box shell, which constitutes the outer shell of the entire refrigeration equipment;

[0151] The inner liner component is arranged in the box shell, and the storage chamber is defined by the inner liner component.

[0152] A foaming cavity is formed between the box shell and the inner liner component, and the foaming cavity is filled with a heat-insulating foaming material.

[0153] The box body 800 is provided with an opening to facilitate the user to take items out of the refrigeration device.

[0154] A door body, mounted at the opening of the box body 800, capable of opening or closing the storage chamber by rotating relative to the box body 800;

[0155] A refrigeration system is provided in the box 800, which is formed by a compressor, a condenser, an evaporator, a solenoid valve and a throttling device connected by a refrigerant pipeline;

[0156] The refrigeration system performs the refrigeration cycle of the refrigeration equipment by using a compressor, a condenser, a solenoid valve, an evaporator and a throttling device.

[0157] A refrigerant circulation loop is formed between the compressor, the condenser, the solenoid valve, the evaporator and the throttling device, so that the refrigerant can circulate among the compressor, the condenser, the solenoid valve, the evaporator and the throttling device.

[0158] The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to achieve refrigeration of the items in the box 800.

[0159] 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.

[0160] The evaporator can cool the items in the cabinet 800 by using the latent heat of evaporation of the refrigerant.

[0161] A compressor room disposed below the storage room is also formed inside the housing 800 .

[0162] The compressor is arranged in the compressor chamber, configured to compress the refrigerant, and is provided with an exhaust pipe connected thereto.

[0163] a condenser, disposed in the compressor chamber and configured to condense the refrigerant;

[0164] an evaporator configured to evaporate the refrigerant condensed by the condenser, the refrigerant evaporated by the evaporator being configured to cool the storage chamber;

[0165] The refrigerant is sucked into the compressor in gaseous form, and after compression it becomes high-temperature and high-pressure superheated vapor, which is discharged from the exhaust pipe connected to the compressor, and enters the condenser through the exhaust pipe. The refrigerant dissipates heat to the surrounding air, and the high-temperature and high-pressure gas is condensed into a high-temperature and medium-pressure liquid, and then passes through the drying filter into the throttling device.

[0166] After the refrigerant enters the throttling device, it is throttled and depressurized due to its narrow and long passage, and then enters the evaporator to vaporize. In the evaporator, the low-temperature and low-pressure refrigerant liquid absorbs a large amount of external heat and vaporizes into dry saturated steam, thereby achieving the purpose of absorbing heat from the outside and refrigerating. In the suction pipe, the refrigerant becomes low-pressure superheated steam and is sucked back by the compressor.

[0167] The ice maker is installed in the box 800 and includes:

[0168] The ice tray comprises: an ice tray main body component 100, with openings formed at both ends;

[0169] The end stopper 300 is connected to the openings at both ends of the ice cube main body component 100 to form an ice-making chamber with a top opening with the ice cube main body component 100;

[0170] A plurality of refrigerant microchannels 110 are formed inside the ice cube tray main body component 100 and are used to be connected to a refrigeration system to transfer the cooling energy of the refrigeration system to the ice cube tray to cool the water inside the ice cube tray into ice cubes.

[0171] In some embodiments of the present application, the ice tray main body component 100 and the evaporator are connected to a refrigeration system in parallel.

[0172] In some embodiments of the present application, the refrigeration system includes a first refrigerant pipeline connected between the solenoid valve and the compressor, and a throttling device and an evaporator are arranged on the first refrigerant pipeline;

[0173] The second refrigerant pipeline is arranged in parallel with the first refrigerant pipeline and connected between the solenoid valve and the compressor. The ice cube main body component 100 is connected to the second refrigerant pipeline.

[0174] In some embodiments of the present application, the ice tray further includes: an inlet manifold component 400, which is respectively connected to the second refrigerant pipeline outlet of the refrigeration system and the inlets of the plurality of refrigerant microchannels 110, and is used to transfer the refrigerant of the refrigeration system to the plurality of refrigerant microchannels 110;

[0175] The outlet manifold component 500 is respectively connected to the second refrigerant pipeline inlet of the refrigeration system and the outlets of the plurality of refrigerant microchannels 110 to transport the refrigerant after heat exchange back to the refrigeration system.

[0176] During the refrigeration cycle, the refrigerant flowing out of the condenser will enter the solenoid valve, and the refrigerant part entering the solenoid valve will flow into the first refrigerant pipeline, and then enter the evaporator, and refrigerate through heat exchange with the air through the evaporator;

[0177] Part of the refrigerant flowing out of the solenoid valve flows into the second refrigerant pipeline, and enters the inlet manifold component 400 connected to the outlet of the second refrigerant pipeline. The refrigerant is diverted to the multiple refrigerant microchannels 110 connected thereto through the inlet manifold component 400. The refrigerant entering the refrigerant microchannels 110 directly exchanges heat with the water in the ice cube main body component 100, absorbs heat, and converts the water in the ice cube into ice. The refrigerant located in the multiple refrigerant microchannels 110 after heat exchange will be collected in the outlet manifold component 500, and the refrigerant will be introduced into the second refrigerant pipeline connected thereto through the outlet manifold component 500, and finally the refrigerant after heat exchange will be returned to the refrigeration system.

[0178] The refrigerant flowing out of the first refrigerant pipeline and the refrigerant flowing out of the second refrigerant pipeline after heat exchange are finally gathered together and flow into the compressor, completing the refrigerant circulation.

[0179] The refrigeration equipment improves the structure of the ice tray assembled therein. Compared with the existing heat conduction method of fitting the ice tray with the ice tray, the ice tray evaporator structure is directly omitted, and the ice tray main body component 100 constituting the main body of the ice tray is directly made into a heat exchange evaporator, and the refrigerant microchannel 110 is directly formed therein. When the ice maker is making ice, the refrigerant of the refrigerant system will flow into each refrigerant microchannel 110, and exchange heat with the water or ice in the ice tray main body component 100 after passing through the ice tray main body component 100. The heat exchange path of the refrigerant is changed from the existing ice evaporator to the ice tray to the water to the ice tray main body component 100 to the water, and the heat exchange path of the refrigerant is shorter, the heat exchange loss is smaller, and the heat exchange speed is faster.

[0180] The refrigerant in the ice tray main body component 100 directly exchanges heat with water, thereby eliminating the contact thermal resistance between the original ice-making evaporation pipe and the ice tray, and the heat exchange thermal resistance is smaller, thereby reducing the heat exchange thermal resistance of the refrigerant and improving the heat exchange efficiency;

[0181] A plurality of refrigerant microchannels 110 are provided in the ice cube main body component 100. During heat exchange, heat can be exchanged with water simultaneously through the plurality of refrigerant microchannels 110. The heat exchange area is greatly increased from the original one ice-making evaporating tube to a distributed plurality of refrigerant microchannels 110, thereby increasing the heat exchange area and improving the heat exchange efficiency.

[0182] In some embodiments of the present application, a plurality of partition components 600 are correspondingly welded on the ice tray main body component 100 , and the partition components 600 are used to partition the ice tray main body component 100 .

[0183] The partition component 600 is welded to the ice cube main body component 100 and forms an integral structure with the ice cube main body component 100. The partition component 600 added to the ice cube main body component 100 is equivalent to adding a fin structure to the ice cube main body component 100 as a heat exchanger. The coldness of the refrigerant in the multiple refrigerant microchannels 110 of the ice cube main body component 100 can also be transferred to the partition component 600 welded and fixed to it. The partition component 600 also contacts the water arranged in the ice storage grid 120 at the same time, and then exchanges heat with the water in the ice storage grid 120, so that the heat exchange area of ​​the entire ice cube is increased from the bottom and side of the ice cube main body component 100 to the bottom, side and side of the ice cube main body component 100, further increasing the heat exchange area of ​​the entire ice cube and enhancing the heat exchange effect of the ice maker. In the description of the above embodiments, specific features, structures, materials or characteristics can be combined in a suitable manner in any one or more embodiments or examples.

[0184] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
