Referring to fig. 1, a regenerator 10 provided in an embodiment of the present application includes a cylinder 11, a return air inlet pipe 12, and an impeller split-flow cap 13. The return air inlet duct 12 includes opposed first and second ends 121, 122, the first end 121 being located on the exterior of the barrel 11 and the second end 122 being located on the interior of the barrel 11. The impeller diversion caps 13 are disposed at the second end 122, and the impeller diversion caps 13 are used to change the flow direction of the return air entering the return air inlet pipe 12 from the first end 121 and guide the return air to rotate and diverge to the inner wall 110 of the barrel 11.

In the regenerator 10 of the application, because the impeller split flow cap 13 is arranged at the second end 122 of the return air inlet pipe 12, and the second end 122 is positioned inside the cylinder body 11, when return air enters the cylinder body 11 through the return air inlet pipe 12, the return air can flow through the impeller split flow cap, so that the flow direction is changed by the impeller split flow cap 13, and the impeller split flow cap 13 can also guide the return air to rotate and diverge, so that the return air can flow into the cylinder body 11 more uniformly, and the heat exchange effect of the return air is improved.

The present application is described in further detail below with reference to the drawings.

Referring to fig. 1, the regenerator 10 includes a barrel 11, a return air inlet pipe 12, and an impeller split-flow cap 13. The return air inlet pipe 12 is provided in the barrel 11, and the impeller split-flow cap 13 is provided in the return air inlet pipe 12. The cylinder 11 is used for supplying return air to enter through the return air inlet pipe 12 so as to exchange heat with exhaust air in the cylinder 11.

The barrel 11 includes opposite first 115 and second 116 ends. The return air inlet pipe 12 is disposed at the first end 115 of the barrel 11, and penetrates the first end 115 of the barrel 11 to be partially disposed inside the barrel 11.

Specifically, the return air inlet duct 12 includes opposite first and second ends 121, 122, the first end 121 of the return air inlet duct 12 being located outside the barrel 11 and the return air outlet duct 14 being located inside the barrel 11. The impeller split cap 13 is disposed at the second end 122 of the return air inlet tube 12.

It will be appreciated that when the return air enters the barrel 11, the return air moves from the first end 115 of the barrel 11 to the second end 116 of the barrel 11, and the return air flows through the first end 121 of the return air inlet pipe 12 to the second end 122 of the return air inlet pipe 12, flows to the impeller split cap 13 disposed at the second end 122, and finally, changes the flow direction of the return air through the impeller split cap 13, and then diverges into the interior of the barrel 11 for heat exchange of the return air.

The impeller splitting cap 13 serves to change the flow direction of the return air entering the return air inlet pipe 12 from the first end 121 and guide the return air to rotate and diverge to the inner wall 110 of the barrel 11.

Specifically, the impeller split-flow cap 13, when changing the flow direction from the first end 121 into the return-air inlet pipe 12, inclines the flow direction of the return air into the barrel 11 with respect to the flow direction of the return air into the first end 121. As can be seen from the above, when the return air enters the first end 121, the flow direction of the return air should be from the first end 115 of the barrel 11 to the second end 116 of the barrel 11, i.e. along the length direction of the barrel 11. The return air changes its flow direction through the impeller split cap 13, and then the return air flows into the barrel 11 from the flow direction along the length of the barrel 11, and is inclined. As shown in fig. 1, when the longitudinal direction of the barrel 11 is the X direction, the flow direction of the return air is changed by the impeller split cap 13, and then the flow direction of the return air may be the P direction or the Q direction.

Referring to fig. 2, in the conventional regenerator 10, a through hole 120 is formed in the return air inlet pipe 12, and when return air enters the return air inlet pipe 12, the return air flows out into the cylinder 11 through the through hole 120, and at this time, the flow direction of the return air is changed from flowing along the length direction L of the cylinder 11 to flowing along the width direction W of the cylinder 11, that is, when the return air enters the cylinder 11, the flow direction of the return air is changed by 90 ° compared with the original flow direction. Thus, the resistance that the return air needs to overcome is greater and the compressor 20 needs to consume more power to ensure that the return air can enter the compressor 20.

In the regenerator 10 of the present application, when the return air passes through the impeller flow dividing cap 13 and enters the interior of the cylinder 11, the flow direction of the return air is changed by the impeller flow dividing cap 13, and the inclination angle is smaller than the original flow direction, that is, the flow direction of the return air is changed by a smaller angle, so that the resistance to be overcome by the return air is smaller, and the power consumed by the compressor 20 can be reduced.

Referring to fig. 1, 3 and 4, the impeller split cap 13 includes a body 131 and blades 132. Wherein the vane 132 is disposed at the second end 122 of the return air inlet pipe 12 through the body 131.

The body 131 is mounted to the second end 122 of the return air inlet duct 12. Specifically, the body 131 is disposed around the vane 132 and is sleeved on the second end 122 of the air return inlet pipe 12, so that the vane 132 is located inside the air return inlet pipe 12, and when the air return flows through the first end 121 to the second end 122 of the air return inlet pipe 12, the air can enter the interior of the barrel 11 through the vane 132.

The vane 132 includes a guide surface 1321. From the above, it can be seen that the vane 132 is located inside the return air inlet pipe 12, i.e., the vane 132 corresponds to the return air inlet pipe 12.

Specifically, the vane 132 has a certain rotation direction so that the guide surface 1321 has an arc surface. When the return air enters the return air inlet pipe 12 to flow to the position of the vane 132, the guiding surface 1321 of the vane 132 can guide the return air to rotate, so that the return air divergently flows to the inner wall 110 of the barrel 11, and the heat exchange effect of the return air is improved.

In one embodiment, the number of blades 132 may be multiple, such as 3, 4, 5, and more. The number of the blades 132 may be determined according to the size of the air return inlet pipe 12, and it is understood that when the size of the air return inlet pipe 12 is larger, the number of the blades 132 may be larger, so that the air return entering the air return inlet pipe 12 with a larger size can be guided, rotated and dispersed by the guiding surface 1321 of the blades 132 with a larger number, so that the air return is dispersed more uniformly.

Specifically, the plurality of blades 132 are spaced apart such that a guide hole 1322 is formed between two adjacent blades 132. The number of guide holes 1322 corresponds to the number of blades 132. For example, if the number of the blades 132 is 4, the number of the guide holes 1322 is also four. When the return air enters the return air inlet pipe 12 and flows to the position where the vane 132 is located, the return air is guided to rotate by the guide surface 1321 and flows to the inner wall 110 of the barrel 11 through the guide hole 1322.

In some embodiments, the rotational direction of the plurality of blades 132 may or may not be uniform. When the rotation directions of the plurality of blades 132 are identical, the return air can be rotated and dispersed in the same rotation direction when flowing into the barrel 11 through the blades 132. When the rotation directions of the plurality of blades 132 are not uniform, the return air can have a plurality of rotation directions and a plurality of dispersion directions when flowing into the barrel 11 through the blades 132, so as to ensure that the return air is more uniformly dispersed.

In certain embodiments, the diameter of the second end 122 of the return air inlet pipe 12 is greater than or equal to the diameter of the first end 121, and the size of the vanes 132 of the impeller splitter cap 13 matches the size of the second end 122. It will be appreciated that when the diameter of the second end 122 of the return air inlet pipe 12 is greater than the diameter of the first end 121, the impeller split cap 13 disposed at the second end 122 is closer to the inner wall 110 of the barrel 11 than the first end 121 of the return air inlet pipe 12 in the radial direction of the barrel 11, so that the return air flowing to the barrel 11 through the impeller split cap 13 can be closer to the inner wall 110 of the barrel 11, so as to further improve the dispersing effect of the return air, and further improve the heat exchange effect of the return air.

In certain embodiments, referring to fig. 1, 4 and 5, the barrel 11 includes a return air inlet 111, a return air outlet 112, an exhaust air inlet 113 and an exhaust air outlet 114. The air return inlet pipe 12 is disposed through the air return inlet 111, such that a first end 121 of the air return inlet pipe 12 is located outside the barrel 11, and a second end 122 of the air return inlet pipe 12 is located inside the barrel 11.

Specifically, the return air inlet 111 and the exhaust air outlet 114 are located at a first end 115 of the barrel 11, and the return air outlet 112 and the exhaust air inlet 113 are located at a second end 116 of the barrel 11. The return air inlet 111 is opposite to the exhaust air inlet 113, and the return air outlet 112 is opposite to the exhaust air outlet 114. The return air enters the interior of the cylinder 11 through a return air inlet pipe 12 positioned at a return air inlet 111, and flows to the exterior of the cylinder 11 through a return air outlet 112; the exhaust gas enters the inside of the cylinder 11 through the exhaust gas inlet 113, and flows to the outside of the cylinder 11 through the exhaust gas.

It will be appreciated that the flow direction of the return air and the flow direction of the exhaust air are opposite, thus ensuring that the return air and the exhaust air are in sufficient contact within regenerator 1010 to increase the heat transfer efficiency of the return air and the exhaust air within regenerator 1010.

Referring to fig. 1, 4 and 6, regenerator 10 further includes a return air outlet pipe 14 and an exhaust pipe 15. Wherein, the return air inlet pipe 12 is used for guiding return air into the barrel 11, the return air outlet pipe 14 is used for guiding return air in the barrel 11 out of the barrel 11, and the exhaust pipe 15 is used for guiding exhaust gas to flow in the exhaust pipe 15.

The return air inlet pipe 12 is provided at the return air outlet 112 and is located outside the barrel 11. It will be appreciated that the return air outlet duct 14 is located at the second end 116 of the barrel 11. When circulating through regenerator 10, the return air passes through return air inlet pipe 12 at first end 115 to circulate into barrel 11, and then flows out through return air outlet pipe 14 at second end 116. That is, the return air flows from the first end 115 of the barrel 11 to the second end 116 of the barrel 11.

In some embodiments, the manner in which the return air inlet pipe 12 is disposed at the return air inlet 111 and the manner in which the return air outlet pipe 14 is disposed at the return air outlet 112 may be: the return air inlet pipe 12 is welded at the return air inlet 111, and the return air outlet pipe 14 is welded at the return air outlet 112, so as to ensure the tightness of the regenerator 10, that is, ensure that return air can only enter through the return air inlet pipe 12 and can only be discharged through the return air outlet pipe 14.

The exhaust pipe 15 is inserted into the barrel 11. Referring to fig. 6 and 7, the exhaust pipe 15 includes an exhaust inlet end 151, an exhaust outlet end 152, and an exhaust passage 153. Wherein the exhaust inlet end 151 extends through the exhaust inlet 113 to the outside of the barrel 11, the exhaust outlet end 152 extends through the exhaust outlet 114 to the outside of the barrel 11, and the exhaust channel 153 is located between the exhaust inlet end 151 and the exhaust outlet end 152. It will be appreciated that the exhaust inlet end 151 is located at the second end 116 of the barrel 11, the exhaust outlet end 152 is located at the first end 115 of the barrel 11, and the exhaust passage 153 is located within the barrel 11.

When the exhaust gas flows in the exhaust pipe 15, the exhaust gas passes through the exhaust gas inlet end 151 at the second end 116 to flow to the exhaust passage 153 in the barrel 11, and then flows out through the exhaust gas outlet end 152 at the first end 115. That is, the exhaust gas flows from the second end 116 of the barrel 11 to the first end 115 of the barrel 11.

In combination with the above-described flowing direction of the return air, the flowing directions of the exhaust gas and the return air are opposite, so that it is ensured that the return air and the exhaust gas can sufficiently contact inside the cylinder 11 to improve the heat exchange efficiency of the regenerator 10.

The exhaust passage 153 has a spiral structure, so that the volume of the exhaust passage 153 in the cylinder 11 is increased, thereby increasing the contact area between the exhaust gas and the return air in the cylinder 11 and improving the heat exchange efficiency of the regenerator 10. In addition, the exhaust channel 153 may further surround at least part of the impeller diversion caps 13 disposed on the air return inlet pipe 12, so that after the air return is discharged through the impeller diversion caps 13 disposed on the air return inlet pipe 12, the air return can be selectively and rotatably sprayed onto the surface of the exhaust channel 153, thereby increasing the contact area between the air return and the exhaust channel 153, and improving the heat exchange efficiency of the regenerator 10.

In one embodiment, referring to fig. 5, the spiral structure of the exhaust channel 153 may abut against the inner wall 110 of the barrel 11. It will be appreciated that the spiral outer diameter of the exhaust passage 153 is slightly smaller than the inner diameter of the barrel 11, so that the overall length of the exhaust passage 153 in the barrel 11, i.e., the overall length of the exhaust pipe 15, can be made longer, thereby increasing the contact area between the exhaust gas and the return gas to increase the heat exchange efficiency of the regenerator 10.

In addition, exhaust inlet end 151 may be welded to exhaust inlet 113, and exhaust outlet end 152 may be welded to exhaust outlet 114, so that return air in barrel 11 may be ensured not to be discharged from exhaust inlet 113 and exhaust outlet 114, i.e., may only be discharged through return air outlet pipe 14, to improve the sealing performance of regenerator 10.

In some embodiments, referring to fig. 8, the return air inlet 111 and the return air outlet 112 may be provided at a port 117 of the barrel 11. And the exhaust inlet 113 and the exhaust outlet 114 may be formed in a sidewall 118 of the barrel 11. In this way, when the return air inlet pipe 12 and the exhaust air outlet 152 are welded to the first end 115 of the cylinder 11, the return air inlet pipe 12 and the exhaust air outlet 152 are prevented from being welded to the same end surface, so as to prevent the exhaust air inlet 113 from being damaged, and similarly, when the return air outlet pipe 14 and the exhaust air inlet 151 are welded to the second end 116 of the cylinder 11, the return air outlet pipe 14 and the exhaust air inlet 151 are prevented from being welded to the same end surface, so that the quality of the regenerator 10 is ensured.

Referring to fig. 5 and 6 in combination, in some embodiments, the barrel 11 may include a first projection 1101 and a second projection 1102. The barrel 11 is hollow.

The first projection 1101 extends from the barrel 11 in a direction away from the first end 115, and the second projection 1102 extends from the barrel 11 in a direction away from the second end 116.

Specifically, the first protruding portion 1101 is disposed at the first end 115, and the second protruding portion 1102 is disposed at the second end 116, and it is understood that the first protruding portion 1101 and the second protruding portion 1102 are disposed opposite to each other.

The air return inlet 111 and the air exhaust outlet 114 are formed in the first protruding portion 1101, and the air return outlet 112 and the air exhaust inlet 113 are formed in the second protruding portion 1102. From the positional relationship of the first projection 1101 and the second projection 1102, it can be seen that the return air inlet 111 and the return air outlet 112 are disposed opposite to each other, the exhaust air inlet 113 and the exhaust air outlet 114 are disposed opposite to each other, and the return air inlet 111 and the exhaust air inlet 113 are disposed opposite to each other, and the return air outlet 112 and the exhaust air outlet 114 are disposed opposite to each other. In this manner, the flow directions of the return air and the exhaust air received by the regenerator 10 are opposite, and thus, it is ensured that the return air and the exhaust air can sufficiently contact in the regenerator 10 to improve the heat exchange efficiency of the return air and the exhaust air in the regenerator 10.

In one embodiment, the first protruding portion 1101 may be connected to the side wall 118 of the barrel 11 by sleeving the first protruding portion 1101 on the first end 115, so that the side wall 11011 of the first protruding portion 1101 is connected to the side wall 118 of the barrel 11 (as shown in fig. 5), or by inserting the first protruding portion 1101 into the first end 115, so that the side wall 11011 of the first protruding portion 1101 is connected to the inner wall 110 of the barrel 11 (as shown in fig. 9).

Similarly, the second protruding portion 1102 may be connected to the side wall 118 of the barrel 11 by sleeving the second protruding portion 1102 on the second end 116, so that the side wall 11021 of the second protruding portion 1102 is connected to the side wall 118 of the barrel 11 (as shown in fig. 4), or by inserting the second protruding portion 1102 into the second end 116, so that the side wall 11021 of the second protruding portion 1102 is connected to the inner wall 110 of the barrel 11 (as shown in fig. 9).

In another embodiment, as shown in fig. 10, the first projection 1101 may be disposed just at the side wall 118 of the first end 115, in other words, the first projection 1101 is entirely located outside the barrel 11 and is connected to the side wall 118. Similarly, the second protruding portion 1102 may be disposed just at the side wall 118 of the second end 116, in other words, the second protruding portion 1102 is entirely located outside the barrel 11 and is connected to the side wall 118.

In some embodiments, referring to fig. 5 and 11, the barrel 11 is hollow, and the first protruding portion 1101 and the second protruding portion 1102 may be formed by being flattened by the barrel 11.

Specifically, in the case where the return air inlet pipe 12, the return air outlet pipe 14 and the exhaust pipe 15 are provided to the barrel 11, the exhaust air inlet end 151 and the exhaust air outlet end 152 of the return air inlet pipe 12, the return air outlet pipe 14 and the exhaust air pipe 151 may be compressed by compressing the barrel 11, so that the first end 115 of the return air inlet pipe 12 and the exhaust air outlet end 152 may be formed as the return air inlet 111 and the exhaust air outlet 114, and the first projection 1101 may be formed; and the second end 116 surrounding the return air outlet pipe 14 and the exhaust air inlet end 151 forms the return air outlet 112 and the exhaust air outlet 114, and forms the second projection 1102.

It can be appreciated that in the process of machining the regenerator 10, only the hollow cylinder 11 needs to be machined first, and the return air inlet 111, the exhaust outlet 114, the return air outlet 112 and the exhaust outlet 114, the first protruding portion 1101 and the second protruding portion 1102 can be formed by compressing the cylinder 11, so that the end of the regenerator 10 can be omitted to form the return air inlet 111, the exhaust outlet 114, the return air outlet 112 and the exhaust outlet 114, damage to the end of the regenerator 10 can be prevented, and the yield can be improved.

Referring to fig. 12, a refrigeration system 100 is provided according to an embodiment of the present application, wherein the refrigeration system 100 includes the regenerator 10, the compressor 20, the condenser 30, the evaporator 40, and the capillary tube 50 according to any of the embodiments described above.

Wherein the outlet of the compressor 20 is in communication with the inlet of the condenser 30, the outlet of the condenser 30 is in communication with the exhaust inlet end 151, the exhaust outlet end 152 is in communication with the inlet of the capillary tube 50, the outlet of the capillary tube 50 is in communication with the inlet of the evaporator 40, the outlet of the evaporator 40 is in communication with the return air inlet pipe 12, and the return air outlet pipe 14 is in communication with the inlet of the compressor 20.

Referring to fig. 12, the gas discharged from the evaporator 40 flows from bottom to top through the return air inlet pipe 12, the cylinder 11 and the return air outlet pipe 14 into the compressor 20. The gas discharged from the condenser 30 flows from the exhaust pipe 15 into the capillary tube 50 from top to bottom. That is, the return air direction of the return air is opposite to the exhaust air direction of the exhaust air, so as to improve the heat exchange efficiency of the regenerator 10. The impeller diversion cap 13 of the regenerator 10 can ensure that the air can flow more uniformly to the exhaust channel 153 of the exhaust pipe 15 of the regenerator 10 under the condition of ensuring that the angle of changing the flowing direction of the air return is smaller, so that the resistance required to be overcome by the air return is smaller, and the heat exchange effect of the regenerator 10 can be ensured while the power consumed by the compressor 20 is ensured.

With continued reference to fig. 12, the following briefly describes the operation of the refrigeration system 100:

the compressor 20 compresses the refrigerant to obtain high-temperature and high-pressure gas (exhaust gas), and the exhaust gas is converted into medium-temperature and high-pressure liquid by the condenser 30, enters the exhaust passage 153 in the cylinder 11 of the regenerator 10 through the exhaust inlet end 151 of the exhaust pipe 15, and is discharged to the capillary tube 50 through the exhaust outlet end 152.

Next, the capillary tube 50 converts the exhaust gas discharged through the exhaust gas outlet 152 into a low temperature and low pressure liquid, and flows into the evaporator 40 to be converted into a low temperature and low pressure return gas, which is circulated through the impeller split cap 13 of the return gas inlet pipe 12 to be rotated and divergently onto the exhaust gas passage 153, and exchanges heat with the exhaust gas in the exhaust gas passage 153 to be converted into an intermediate temperature and medium pressure exhaust gas, and enters the compressor 20. In this way, the refrigeration cycle of the refrigeration system 100 is completed.

The refrigeration device 1000 may further include a housing, wherein the refrigeration system 100 or the regenerator 10 is disposed inside the housing.

In regenerator 10, refrigerating system 100 and refrigeration plant 1000 of this application, because impeller reposition of redundant personnel cap 13 set up at the second end 122 of return air inlet tube 12, and second end 122 is located inside barrel 11, when the return air passes through return air inlet tube 12 and gets into in barrel 11, the return air can be through impeller reposition of redundant personnel cap 13 to by impeller reposition of redundant personnel cap 13 change flow direction, and impeller reposition of redundant personnel cap 13 still can guide the return air to take place to rotate and diverge, so that the return air can more even flow to in the barrel 11, thereby promote the heat transfer effect of return air.
