Referring to fig. 1 and 2, a regenerator 10 is provided in accordance with an embodiment of the present disclosure. Regenerator 10 includes a return tube 12, an exhaust tube 14, and a shunt tube 16. The air return pipe 12 includes a barrel 121, and a return air inlet 123 and a return air outlet 125 protruding from the barrel 121. The exhaust pipe 14 penetrates the barrel 121. The shunt cylinder 16 is disposed inside the cylinder body 121 and forms an air return channel 18 with the inner wall of the cylinder body 121. The exhaust pipe 14 surrounds the flow dividing cylinder 16 and is located at least partially in the return air passage 18, and the flow dividing cylinder 16 serves to change the flow direction of return air entering from the inlet end of the return air inlet portion 123 and to guide the return air to the exhaust pipe 14.

It should be noted that the muffler 12 and the exhaust pipe 14 are isolated from each other, that is, the low-temperature refrigerant in the muffler 12 and the high-temperature refrigerant in the exhaust pipe 14 exchange heat without contacting each other, so as to avoid the decrease of heat exchange efficiency due to the leakage of the refrigerant between the muffler 12 and the exhaust pipe 14, which affects the refrigeration effect.

The heat regenerator 10 of the embodiment of the present application is through setting up the blast pipe 14 in the muffler 12 to guide the return air that the muffler 12 got into to the blast pipe 14 through reposition of redundant personnel section of thick bamboo 16, make the return air in the muffler 12 fully exchange heat with the exhaust in the blast pipe 14, and because reposition of redundant personnel section of thick bamboo 16 can change the direction of return air, can carry out the vortex to the return air of muffler 12 inside, thereby further improve the heat exchange efficiency of muffler 12 and blast pipe 14, can reach better refrigeration effect.

In some embodiments, the exhaust pipe 14 is spirally disposed inside the barrel 121, the spiral pipe bending process is simple, the exhaust gas flows through the exhaust pipe 14 and centrifugally rotates, the return gas flows through the exhaust pipe 14 from the return gas inlet 123 to exchange heat, and then is output through the return gas outlet 125, and the heat exchange area and the heat exchange efficiency between the return gas and the exhaust gas are sufficiently increased by using a counter-current heat exchange manner.

In some embodiments, the exhaust pipe 14 and the shunt cylinder 16 may be connected by welding, bonding, or the like, so as to install the shunt cylinder 16 in the space spirally formed by the exhaust pipe 14, and ensure that the shunt cylinder 16 is fixed in position, so as to change the air return direction.

Referring to fig. 2 and 3, in some embodiments, the outer diameter d1 of the splitter cylinder 16 is smaller than or equal to the inner diameter d2 of the spiral of the exhaust pipe 14. Specifically, the partial flow cylinder 16 is arranged in the space formed by the spiral of the exhaust pipe 14, so that the return air entering the cylinder body 121 through the return air inlet part 123 can be effectively guided to the exhaust pipe 14, the turbulent flow of the return air is realized, and the heat exchange efficiency is improved.

With continued reference to fig. 2 and 3, in some embodiments, the exhaust pipe 14 has a spiral outer diameter d3 greater than or equal to the inner diameter d4 of the barrel 121. Specifically, compared to when the outer diameter d3 of the spiral is smaller than the inner diameter d4 of the cylinder 121, the exhaust pipe 14 is not fixed in the cylinder 121 conveniently, and when the exhaust pipe 14 is impacted by return air, the exhaust pipe 14 collides with the inner wall of the cylinder 121 to generate noise, which causes the noise of the regenerator 10 to increase; the utility model provides an external diameter d3 of 14 spirals of blast pipe is greater than or equal to internal diameter d4 of stack 121, because of the main material of blast pipe 14 is copper, therefore blast pipe 14 has certain ductility, and blast pipe 14 can contradict with stack 121 inner wall, and then weakens the noise that the collision produced between the inner wall of blast pipe 14 and stack 121.

Referring to fig. 2, in some embodiments, the shunt tube 16 may include a main body 161 and a first drainage portion 162. An air return channel 18 is formed between the main body 161 and the inner wall of the cylinder 121, and the air return channel 18 ensures that the return air entering the cylinder 121 from the air return inlet 123 can flow to the air return outlet 125 through the air return channel 18, thereby ensuring normal circulation of the return air. First flow guiding portion 162 is located the one end that main part 161 is close to return air inlet portion 123 for the change is from the flow direction of the return air that the entry end of return air inlet portion 123 got into, and will be from the return air direction return air passageway 18 of the entry end entering of return air inlet portion 123 in, improve the heat transfer area between return air and the blast pipe 14, promote heat exchange efficiency.

With continued reference to fig. 2, the flow diversion cylinder 16 may further include a second diversion part 163, and the second diversion part 163 is located at one end of the main body part 161 near the return air outlet part 125, and is used for guiding the return air to the return air outlet part 125.

In some embodiments, the flow dividing cylinder 16 is a cylindrical structure, and both ends of the flow dividing cylinder 16 are in a closed state, so that the return air can be prevented from directly entering the flow dividing cylinder 16 and flowing to the return air outlet 125, the flow direction of the return air is changed, and compared with the case that the return air directly passes through the spiral center of the exhaust pipe 14, the contact area between the return air and the exhaust pipe 14 is higher, and the heat exchange efficiency is improved.

In some embodiments, one end of the flow distribution cylinder 16 close to the air return inlet 123 is closed, one end of the flow distribution cylinder 16 close to the air return outlet 125 is not closed, and the flow distribution cylinder 16 is a hollow structure, so that the weight of the flow distribution cylinder 16 can be reduced, the production cost can be reduced, and the installation and fixation of the flow distribution cylinder 16 can be facilitated. In addition, the reposition of redundant personnel section of thick bamboo 16 that the cavity set up is when changing the return-air direction, and the partial fluid that the return-air carried can get into reposition of redundant personnel section of thick bamboo 16 in for reposition of redundant personnel section of thick bamboo 16 has the effect of stock solution.

In some embodiments, the first flow guiding part 162 is a cone structure, such as a cone, a triangular pyramid, a rectangular pyramid, etc., the tip of the cone structure faces the air return inlet 123, and the return air entering the barrel 121 from the air return inlet 123 is guided into the return air channel 18 through the side of the cone structure.

In some embodiments, the center line of first flow guiding portion 162 coincides with the center line of inlet portion 123 for returning air, and it is guaranteed that the returning air can be directly changed in flow direction by first flow guiding portion 162 after entering barrel 121, and the guide effect is better, improves the area of contact of returning air and exhaust pipe 14, promotes heat exchange efficiency. In other embodiments, the center line of the first flow guiding part 162, the center line of the second flow guiding part 163, the center line of the air return inlet part 123, and the center line of the air return outlet part 125 are overlapped, so that the flow dividing cylinder 16 has a simple processing technology, and can improve the guiding effect of the first flow guiding part 162 and the second flow guiding part 163 on the return air, thereby facilitating the flow and the guide of the return air in the cylinder body 121.

Referring to fig. 4, in some embodiments, the flow dividing cylinder 16 is a mesh structure 165, a plurality of mesh gaps are formed inside the mesh structure 165, and the mesh gaps are used for guiding return air entering from the inlet end of the return air inlet portion 123 to the exhaust pipe 14 after forming turbulent flow, so as to increase the heat exchange area between the return air and the exhaust pipe 14 and improve the heat exchange efficiency. In addition, the shunt tube 16 configured as the net-shaped structure 165 can filter iron filings and other impurities generated by the operation of the compressor 50, so as to prevent the iron filings and other impurities from causing blockage or causing noise to the whole refrigeration system 100. It should be noted that the mesh gaps of the mesh structure 165 may be irregular gaps, for example, a steel wire ball used for dish washing may be referred to, so that the return air entering from the inlet end of the return air inlet portion 123 cannot directly flow through the center of the regenerator 10, but is guided into the surrounding return air channel 18 to exchange heat with the exhaust pipe 14, thereby improving the heat exchange efficiency.

In some embodiments, when the cartridge 121 is mounted to the refrigeration appliance 1000 (shown in fig. 7), the top of the cartridge 121 is higher than the bottom of the cartridge 121 relative to the bottom of the refrigeration appliance 1000. The return air inlet 123 is located at the top of the cylinder 121, and the return air outlet 125 is located at the bottom of the cylinder 121. Or, the return air inlet 123 is located at the bottom of the cylinder 121, and the return air outlet 125 is located at the top of the cylinder 121 (shown in fig. 7), so that when the air in the return air flows upwards, the liquid flows downwards under the action of gravity, so that the heat regenerator 10 has the effect of storing liquid, a liquid storage device is not required to be separately arranged, and the liquid is prevented from entering the compressor 50 through the return air pipe 12, which causes a liquid impact phenomenon and damages the compressor 50.

Referring to fig. 4, in some embodiments, the exhaust pipe 14 is disposed through the muffler 12, the exhaust pipe 14 includes an exhaust inlet 141 and an exhaust outlet 143 opposite to each other, the exhaust inlet 141 extends from the muffler outlet 125 to the outside of the muffler 12, and the exhaust outlet 143 extends from the muffler inlet 123 to the outside of the muffler 12. In this way, the exhaust gas of the exhaust pipe 14 flows from the exhaust inlet port 141 to the exhaust outlet port 143, the return air of the return air pipe 12 flows from the return air inlet portion 123 to the return air outlet portion 125, and since the exhaust inlet port 141 and the return air outlet portion 125 are located on the same side and the exhaust outlet port 143 and the return air inlet portion 123 are located on the same side, the flow directions of the exhaust gas and the return air are opposite, and thus the heat exchange efficiency of the exhaust gas and the return air is improved.

Referring to fig. 2 and 4, in some embodiments, the sidewall of the return air inlet 123 is provided with a first through hole 1231, and the exhaust outlet 143 extends from the first through hole 1231 to the outside of the return air inlet 123 and is hermetically welded to the first through hole 1231. The side wall of the return air outlet portion 125 is provided with a second penetration hole 1251, and the exhaust gas inlet port 141 protrudes from the second penetration hole 1251 to the outside of the return air outlet portion 125, and is seal-welded to the second penetration hole 1251. Exhaust outlet end 143 seal welding is in first perforation 1231, and exhaust inlet end 141 seal welding is in second perforation 1251, has increased the leakproofness in whole heat transfer gas circuit in the chamber, avoids taking a breath in the gas circuit gaseous or the excessive of liquid, makes the heat transfer area between blast pipe 14 and muffler 12 grow on the one hand, strengthens heat transfer effect, promotes heat exchange efficiency, and on the other hand can avoid excessive damage and the noise production that causes the device.

Referring to fig. 5, in some embodiments, the barrel 121 may be provided with a first through hole 1211 and a second through hole 1213, for example, the first through hole 1211 is provided at one end of the barrel 121, the second through hole 1213 is provided at the opposite end, the exhaust inlet port 141 penetrates through the first through hole 1211 to the outside of the barrel 121 and is hermetically welded to the first through hole 1211, and the exhaust outlet port 143 penetrates through the second through hole 1213 to the outside of the barrel 121 and is hermetically welded to the second through hole 1213. Of course, in another example, the exhaust inlet port 141 may protrude from the second through hole 1251 of the return air outlet 125 to the outside of the return air outlet 125, and the exhaust outlet port 143 penetrates from the second through hole 1213 of the barrel 121 to the outside of the barrel 121. In still another example, the exhaust inlet port 141 penetrates out of the first through hole 1211 of the cylindrical body 121 to the outside of the cylindrical body 121, and the exhaust outlet port 143 protrudes out of the first through hole 1231 of the air return inlet portion 123 to the outside of the air return inlet portion 123.

It should be noted that, in some embodiments, the sealing of the through hole may also be a packing seal, a thread seal, or the like, which is not limited herein. The heat regenerator 10 seals the through hole, and ensures that the return air and the exhaust air cannot leak, so that the refrigeration effect is reduced, and the compressor 50 cannot be cooled to cause damage.

In some embodiments, the exhaust pipe 14 inside the cylinder 121 of the regenerator 10 according to any of the above embodiments may be a capillary tube, that is, the exhaust pipe 14 inside the cylinder 121 may be a capillary tube completely; or the middle part of the exhaust pipe 14 in the cylinder body 121 is a capillary, and the other part is the exhaust pipe 14; or the exhaust pipe 14 inside the cylinder 121 does not include a capillary tube. The exhaust pipe 14 is partially set to be a capillary tube, so that the refrigerant can be throttled while exchanging heat, the refrigerant flowing out of the exhaust pipe 14 is guaranteed to be in a supercooled liquid state before throttling, and the throttling effect is improvedThe refrigerant sound in the throttling process is reduced.

Referring to fig. 2, specifically, after heat exchange is performed between a high-temperature refrigerant and a low-temperature refrigerant in the heat regenerator 10, the low-temperature refrigerant is throttled and depressurized by the throttling component 40 before flowing to the evaporator 30, and compared with a method of throttling while depressurizing at the same time, a better depressurization effect can be achieved by utilizing a method of first concentrating cooling and then throttling, that is, a constant-temperature depressurization method, to reduce the pressure while throttling, thereby enhancing the refrigeration efficiency of the evaporator 30. The dry filter 20 is mainly used to remove excess moisture and part of impurities in the refrigeration system 100, so as to prevent the refrigeration system 100 from being blocked.
