Referring to fig. 1, fig. 1 is a schematic structural diagram of a refrigeration apparatus according to some embodiments of the present application.

The refrigeration equipment 1000 comprises a compressor 10, a condenser 20, a throttling device 30 and an evaporator 40 which are sequentially connected through pipelines to form a closed system, refrigerant circularly flows in the system, and the state change is continuously generated during the flowing process, so that the refrigeration purpose is achieved.

The refrigeration device 1000 may be a refrigerator, an ice chest, an air conditioner, or other devices that can be used for refrigeration.

Specifically, the refrigeration principle of the refrigeration apparatus 1000 is as follows: the compressor 10 sucks the low-temperature and low-pressure gaseous refrigerant generated in the evaporator 40, maintains the low-pressure state in the evaporator 40, creates a condition that the liquid refrigerant in the evaporator 40 is continuously boiled (gasified) at low temperature, and the low-temperature and low-pressure gaseous refrigerant sucked by the compressor 10 is compressed, and the temperature and the pressure are increased, creating a condition that the gaseous refrigerant can be liquefied at normal temperature. The high-temperature high-pressure gaseous refrigerant is discharged into the condenser 20, is cooled by a cooling medium (such as air) under the condition that the pressure is kept unchanged, is further condensed into a high-pressure liquid refrigerant, is discharged from the condenser 20, passes through the throttling device 30, is throttled and then is changed into a low-temperature low-pressure liquid state to enter the evaporator 40, wet steam absorbs the heat of the cooling medium under the condition that the pressure is unchanged in the evaporator 40 to be gasified, and the formed low-temperature low-pressure gaseous refrigerant is sucked by the compressor 10 again, so that the cycle is repeated.

The throttling device 30 may be a throttling capillary tube, an electronic expansion valve, a thermal expansion valve, or other devices that can be used for throttling a pipeline.

In some embodiments, the throttling device 30 is a throttling capillary tube connected between the condenser 20 and the evaporator 40. The evaporator 40 is connected to the compressor 10 through a return pipe.

In order to improve the efficiency of the compressor 10 and reduce energy loss, the temperature of the low-temperature low-pressure gaseous condensing agent in the return pipe needs to be increased by means of the high-temperature high-pressure liquid condensing agent in the throttling capillary pipe, and the throttling capillary pipe is arranged in contact with the return pipe, so that the low-temperature low-pressure liquid refrigerant in the return pipe can be preheated before entering the compressor 10, the efficiency of the compressor 10 is improved, and the cooling of the high-temperature high-pressure liquid refrigerant in the throttling capillary pipe can be promoted. However, the air return pipe and the throttling capillary pipe are arranged in a contact manner, which is generally in line contact, and the defect of small contact area exists, so that the heat exchange efficiency is low, and therefore, the length of the air return pipe and the length of the throttling capillary pipe are generally long, and the pipeline cost is high. And the air return pipe and the throttling capillary are usually fixed in an adhesive or tin soldering mode, so that the air return pipe and the throttling capillary are easy to fall off, and the maintenance cost is increased.

Therefore, the size and cost of the pipeline are reduced to improve the return air heat exchange efficiency of the refrigeration equipment 1000. Referring to fig. 2 and 3, fig. 2 is a schematic structural diagram of a regenerator provided in some embodiments of the present application, and fig. 3 is a schematic cross-sectional structural diagram of the regenerator in the embodiment of fig. 2.

In some embodiments, regenerator 50 includes a return tube 100, a throttle capillary tube 200, and a flow splitter 300.

The air return pipe 100 has an air return chamber 101, and a first interface 102 and a second interface 103 respectively connected to the air return chamber 101. The first connection 102 is used to connect the outlet of the evaporator 40 in the refrigeration device 1000, and the second connection 103 is used to connect the return port of the compressor 10 in the refrigeration device 1000. The low-temperature and low-pressure gaseous refrigerant in the evaporator 40 enters the return air chamber 101 through the first port 102 and is then discharged to the compressor 10 through the second port 103 to be compressed.

The choke capillary 200 has a first capillary segment 210, a second capillary segment 220, and a third capillary segment 230 connected in series. The first capillary segment 210 and the third capillary segment 230 are disposed outside the muffler 100. The first capillary segment 210 is used for connecting with the outlet of the condenser 20 of the refrigeration apparatus 1000, and the third capillary segment 230 is used for connecting with the inlet of the evaporator 40 of the refrigeration apparatus 1000. The second capillary segment 220 is received in the return air tube 100, i.e. in the return air chamber 101. Through the arrangement, the second capillary tube section 220 can be immersed in the refrigerant in the air return cavity 101, and the heat exchange efficiency of the high-temperature and high-pressure liquid refrigerant in the throttling capillary tube 200 and the low-temperature and low-pressure gaseous refrigerant in the air return cavity 101 is greatly improved.

The flow splitter 300 includes a main body portion 310, a first flow-splitting portion 320, and a second flow-splitting portion 330. The first and second flow dividing parts 320 and 330 are provided at both ends of the body part 310, respectively. The first diverging portion 320 extends toward the first port 102, and the second diverging portion 330 extends toward the second port 103. The flow divider 300 is accommodated in the muffler 100, and blocks the flow of the coolant in the muffler 100, occupying the flow space of the coolant, so as to reduce the flow rate of the coolant in the muffler 100. The first and second diverging parts 320 and 330 are for guiding the flow of the refrigerant, thereby preventing the refrigerant from stagnating due to the existence of the diverging member 300. Specifically, when the low-temperature and low-pressure gaseous refrigerant in the return air chamber 101 flows to the first branch portion 320, the refrigerant is branched to the circumferential side of the main body portion 310 and flows continuously, and is guided to the second connection port 103 when flowing to the second branch portion 330.

The second capillary segment 220 accommodated in the air return chamber 101 may be located between the inner wall of the air return chamber 100 and the outer wall of the flow divider 300, so that the refrigerant flowing to the periphery of the main body 310 under the influence of the first flow divider 320 may flow through the second capillary segment 220 and exchange heat with the refrigerant in the second capillary segment 220. To improve the heat exchange efficiency, the second capillary segment 220 may be spiral and surround the flow divider 300. In other words, the second capillary segment 220 may be a helical segment coiled around the shunt 300. In addition, in order to further improve the heat exchange efficiency, the second capillary segment 220 may be connected between the inner wall of the air return pipe 100 and the outer wall of the flow divider 300, that is, the opposite two side portions of the second capillary segment 220 are respectively abutted against the inner wall of the air return pipe 100 and the outer wall of the flow divider 300, so that the condensing agent in the air return chamber 101 is certainly contacted with the second capillary segment 220 when flowing through the peripheral side of the main body portion 310, and the heat exchange efficiency of the liquid condensing agent with high temperature and high pressure in the throttling capillary 200 and the gaseous condensing agent with low temperature and low pressure in the air return chamber 101 is greatly increased.

Of course, in other embodiments, the second capillary segment 220 may not be connected to the inner wall of the muffler 100 and/or the outer wall of the flow divider 300, for example, the second capillary segment 220 may be attached to the inner wall of the muffler 100 without contacting the flow divider 300, may be attached to the outer wall of the flow divider 300 without contacting the muffler 100, or may be located between the muffler 100 and the flow divider 300 without contacting the same, which is not limited herein.

In some embodiments, the return air duct 100 includes a first return air duct section 110, a second return air duct section 120, and a third return air duct section 130 connected in series. The first return air pipe section 110, the second return air pipe section 120 and the third return air pipe section 130 are communicated with each other to form a return air chamber 101. The first interface 102 is disposed at an end of the first return air pipe section 110 facing away from the second return air pipe section 120. The second interface 103 is disposed at an end of the third return air pipe section 130 away from the second return air pipe section 120.

The first return air pipe section 110 and the third return air pipe section 130 are smaller in radial size than the second return air pipe section 120. The first capillary segment 210 is disposed through the first return pipe segment 110. The second capillary segment 220 is received in the second return air segment 120. The third capillary segment 230 is disposed through the third return air segment 130. By the above design, the pipeline size of the regenerator 50 can be greatly reduced, and the pipeline size can be one tenth to one twentieth of the prior art.

The first air return pipe segment 110 is provided with a first communication port 1101, and the first capillary segment 210 can penetrate through the first air return pipe segment 110 through the first communication port 1101. The third air return pipe section 130 is opened with a second communication port 1301, and the third capillary section 230 can penetrate through the third air return pipe section 130 through the second communication port 1301. In a specific implementation scenario, the first communication port 1101 and the second communication port 1301 may be provided at other positions of the muffler 100 as needed, and are not limited to this embodiment.

Optionally, the throttle capillary 200 is welded and fixed to the muffler 100, and the first communication port 1101 and the second communication port 1301 are both corresponding welded holes. Of course, the throttle capillary 200 can be fixed to the muffler 100 by other fixing connection means.

In some embodiments, the first and second dividers 320 and 330 have chamfered surfaces extending from the middle portion to the peripheral portion, so that the first divider 320 can guide the refrigerant in the return pipe 100 to the peripheral side, and the second divider 330 can guide the refrigerant of the peripheral side to the middle portion.

In some embodiments, the second return air duct section 120 is a cylindrical pipe, the main body portion 310 is a cylinder having a smaller radial dimension than the second return air duct section 120, and the first and second flow-dividing portions 320 and 330 are cones provided at both ends of the main body portion 310. I.e. the cross-sections of the second return gas pipe section 120 and the flow divider 300 are circular. The radius of curvature of the second capillary segment 220 may be designed corresponding to the second return air segment 120 and/or the main body 310 to maximize the contact area between the second capillary segment 220 and the second return air segment 120 and/or the main body 310, so as to facilitate the installation and fixation of the second capillary segment 220.

In other embodiments, the second return air duct segment 120, the splitter 300, may also be other shapes, including but not limited to oval, rectangular, etc. in cross-section. For example, the second return air pipe section 120 has a rectangular cross section, the main body 310 has a smaller radial dimension than the rectangular cross section of the second return air pipe section 120, and the first and second flow-dividing parts 320 and 330 are pyramids disposed at two ends of the main body 310. Of course, the second return pipe section 120 and the flow divider 300 may also have different shaped cross-sections, respectively. In addition, the cross-section of the first return pipe segment 110 and the third return pipe segment 130 may also be circular, oval, rectangular, and the like, which may be designed according to the actual implementation scenario, and is not limited herein.

In some embodiments, the second capillary segment 220 is rectangular in cross-section. The second capillary segment 220 with a rectangular cross section can be attached to the inner wall of the second return air pipe segment 120 and/or the outer wall of the main body part 310, and the contact mode of the second capillary segment 220 and the inner wall of the second return air pipe segment 120 and/or the outer wall of the main body part 310 is changed from line contact to surface contact, so that the contact area of the second capillary segment 220 and the second return air pipe segment 120 and/or the main body part 310 is greatly increased, and the second capillary segment 220 can be conveniently installed and fixed.

Of course, the cross section of the second capillary segment 220 may also be circular, oval, etc., and is not limited herein.

The electronic control component can also be provided with a convex part matched with the groove so as to realize clamping and positioning.

In some embodiments, the positioning part 401 is a convex part provided on the heat conductive member 400. The shape of the protrusion can be designed according to actual implementation scenarios, and a groove or a through hole is correspondingly formed in the electronic control component to be mounted on the heat conducting member 400, so that the protrusion can be inserted into the corresponding position of the component to position the component on the heat conducting member 400.

Of course, the first predetermined angle may be slightly larger or smaller than 90 degrees, such as 80 degrees, 85 degrees, 95 degrees, 100 degrees, etc. The second preset angle is generally greater than or equal to 90 degrees, so that the size of the mounting position 402 is enlarged, the electronic control component 60 is convenient to mount, meanwhile, the electronic control component 60 is prevented from falling off, and the stability of the mounting structure is improved. For example, the second preset angle may be 90 degrees, 100 degrees, 110 degrees, 120 degrees, etc. Of course, when the electrically controlled component 60 is smaller, the second predetermined angle may also be designed to be smaller than 90 degrees, so as to improve the stability of the electrically controlled component 60 in the mounting position 402. For example, the second preset angle may be 80 degrees, 70 degrees, 60 degrees, etc.
