[0027] Reference Figure 1 、 Figure 2 , Figure 1 、 Figure 2 A heat exchange assembly 100 is shown schematically. The heat exchange assembly 100 includes a heat exchanger core 1 and a valve assembly 2, which are fixedly mounted. The heat exchanger core 1 comprises a plurality of stacked plates 11, with adjacent plates 11 welded to each other. Each plate 11 has at least a first orifice and a second orifice. Along the stacking direction of the plates, the first orifices of each plate 11 are aligned, and the second orifices of each plate 11 are aligned. The first and second orifices are located adjacent to the edges of the plates 11, allowing the fluid flowing through the plates to have a longer flow path, thereby improving heat exchange efficiency.

[0028] Reference Figure 2-Figure 10The heat exchanger core 1 has at least a first flow channel 12 and a second flow channel, wherein the fluid in the first flow channel 12 and the second flow channel can exchange heat inside the heat exchanger core; the heat exchanger core may also have a third flow channel or a fourth flow channel. The heat exchanger core includes a plurality of first-type plates and a plurality of second-type plates that are stacked, and the first-type plates and the second-type plates are stacked to form the first flow channel and the second flow channel; the first-type plates include a first orifice, a second orifice, and a third orifice; the second-type plates include a first orifice and a second orifice, and the second-type plates do not have the third orifice, and along the length or width direction of the heat exchanger core, the third orifice is located between the first orifice and the second orifice; wherein in the length or width direction of the heat exchanger core, the third orifice is located between the first orifice and the second orifice, which means that the first orifice and the second orifice may not be aligned, but for example in the length direction of the heat exchanger core, the third orifice may be located in an area between the first orifice and the second orifice, or for example in the width direction of the heat exchanger core, the third orifice may be located in an area between the first orifice and the second orifice.

[0029] The heat exchanger core 1 includes a first fluid path 121, an inter-plate path 122, a second fluid path 123, and a third fluid path 1224. The first fluid path 121 is formed at the first orifice of the first and second types of plates, the second fluid path 123 is formed at the second orifice of the first and second types of plates, and the third fluid path 1224 is formed at the third orifice of the first type of plate. The inter-plate path 122 connects the first fluid path 121, the second fluid path 123, and the third fluid path 1224. Since stacking adjacent plates will form at least two inter-plate paths for two fluids, the inter-plate path 122 here specifically refers to the fluid path between adjacent plates, and this fluid path is part of the first flow channel and is connected to the first fluid path, the second fluid path, and the third fluid path. Herein, the first fluid path 121 includes (but is not limited to) one channel and can have two or more channels, and the second fluid path 123 includes (but is not limited to) one channel and can have two or more channels.

[0030] The valve assembly 2 includes a valve body 21, a valve core component 22, a sensor 23, and a circuit board 24. The valve body 21 has a first cavity 211 and a second cavity 212. At least part of the valve core component 22 is located in the first cavity 211, and at least part of the sensor 23 is located in the second cavity 212. The sensor senses the temperature and / or pressure of the inter-plate path, wherein the second cavity 212 can be connected to the inter-plate path 122; the sensor 23 is electrically connected to the circuit board 24.

[0031] In the illustrated structure, sensor 23 extends into heat exchanger core 1. Alternatively, sensor 23 can be positioned above the heat exchanger core. The second cavity housing sensor 23 communicates with inter-plate path 122, allowing sensor 23 to collect information about the pressure and / or temperature of the fluid flowing through the core. Extending sensor 23 into the heat exchanger core further reduces the sensor's protrusion from the core, contributing to a smaller footprint.

[0032] The heat exchange assembly has an insertion portion 213 , which is located in the first fluid path 121 . At least a portion of the valve core component extends into the inner cavity of the insertion portion 213 , and the valve core component is sealed to the inner wall of the insertion portion 213 .

[0033] The valve core component 22 includes a valve core 221, a rotor assembly 222, and a stator assembly 223. The stator assembly 223 is sleeved on the outer periphery of the rotor assembly 222, and the stator assembly 223 is electrically connected to the circuit board 16; the valve assembly 2 also has a valve port 220, and the valve port 220 can connect the flow channels located on both sides of the valve port 220; in this embodiment, the valve body 21 also includes a valve seat 224, and the valve seat 224 is arranged on the outer periphery of the valve core 221 and is limited. The valve port 220 is formed on the valve seat 224, and the valve core 221 changes the flow cross-sectional area of the working medium at the valve port 220 by approaching and moving away from the valve port 220, thereby being able to form throttling at the valve port 220. When the valve assembly 2 is working, the current in the winding of the stator assembly 223 is controlled to change according to a predetermined rule, thereby controlling the stator assembly 223 to generate a changing excitation magnetic field. The rotor assembly 222 rotates under the action of the excitation magnetic field. The rotor assembly 222 can drive the valve core 221 to move relative to the valve port 220 and adjust the opening of the valve port 220; in this way, the rotor assembly can drive the valve core to move relative to the valve port. This method of controlling the opening of the valve core relative to the valve port by controlling the current passing through the stator assembly is conducive to improving the control accuracy of the flow rate.

[0034] The valve body 21 is welded and fixed to the heat exchanger core 1. In one embodiment, the heat exchanger core 1 includes a top plate 113, multiple intermediate plates 114, and a bottom plate 115. The multiple intermediate plates 114 are located between the top plate 113 and the bottom plate 115. The top plate 113, multiple intermediate plates 114, and the bottom plate 115 are welded and fixed. The valve body 21 is welded and fixed to the top plate 113, or the valve body 21 is welded and fixed to the bottom plate 115. In other embodiments, the heat exchanger core includes a connector, a top plate, multiple intermediate plates, and a bottom plate. The multiple intermediate plates are located between the top plate and the bottom plate. The top plate, multiple intermediate plates, and the bottom plate are welded and fixed. The valve body is welded and fixed to the connector, the connector is welded and fixed to the top plate, or the connector is welded and fixed to the bottom plate. In other embodiments, the heat exchanger core includes a connector, a top plate, multiple intermediate plates, and a bottom plate. The multiple intermediate plates are located between the top plate and the bottom plate. The top plate, multiple intermediate plates, and the bottom plate are welded and fixed. The connector is welded and fixed to the bottom plate, and the valve body is welded and fixed to the top plate. In another embodiment, the heat exchanger core includes a connector, a top plate, multiple intermediate plates, and a bottom plate. The multiple intermediate plates are positioned between the top plate and the bottom plate. The top plate, multiple intermediate plates, and bottom plate are welded together. The connector is welded together with the top plate, and the valve body is welded together with the top plate. The connector can be in the form of a connecting plate or a connecting block.

[0035] In the illustrated structure, the insertion portion 213 is integrally formed with the valve body 21. The valve body 21 includes a first side portion 214 and a second side portion 215. The first side portion 214 cooperates with the valve core component, and the second side portion 215 cooperates with the heat exchanger core 1. The second side portion 215 is welded to the heat exchanger core 1. The insertion portion 213 is protruding from the second side portion 215. The first cavity 211 extends through the insertion portion 213. The first cavity 211 extends through the first side portion 214 and the second side portion 215, and the second cavity 212 extends through the first side portion 214 and the second side portion 215.

[0036] The valve body 21 has a first through hole 216, and the second side portion 215 has a first groove 2151. The first groove 2151 connects the first through hole 216 with the first cavity 211. When the second side portion 215 is welded to the heat exchanger core 1, the first groove 2151 and the heat exchanger core 1 cooperate to form a flow channel.

[0037] The extension portion 213 has a port portion 2131 and a root portion 2132, the root portion 2132 has a notch 2133, the notch 2133 is connected to the first groove 2151, the valve core component has a valve seat 224, the valve seat 224 is provided with a throttling inlet 2240, the throttling inlet 2240 is opened on the peripheral wall of the valve seat 224, and the flow area of the notch 2133 is larger than the flow area of the throttling inlet 2240.

[0038] The opening depth of the notch 2133 at the root 2132 along the stacking direction of the plates is greater than that of the first groove 2151, and the notch 2133 is partially located inside the heat exchanger core 1. In this way, when the valve core component is located in the extension portion 213 and when the throttling inlet 2240 is located inside the heat exchanger core 1, it can be seen from the figure that when it is located below the top plate 113, the opening depth of the notch 2133 is greater than that of the first groove 2151, so that the fluid can flow into the throttling inlet 2240 through the deeper notch 2133 from the first groove 2151, so that the valve core component can be extended into the deeper interior of the heat exchanger core, which helps to reduce the height of the valve assembly protruding from the heat exchanger core and reduce the size.

[0039] The heat exchange assembly 100 includes a drainage tube 3, which is located in the first fluid path 121. The valve core component includes a throttle outlet channel 2241. The inner cavity of the drainage tube 3 is connected to the throttle outlet channel 2241. The first fluid path 121 includes a first sub-path 1211 and a second sub-path 1212. The first sub-path 1211 is connected to the inner cavity of the drainage tube 3, and the second sub-path 1212 is located outside the drainage tube 3.

[0040] The heat exchanger core 1 includes a first blocking portion 13, which is located on the second fluid path 123. The second fluid path 123 includes a third sub-path 1231 and a fourth sub-path 1232. The third sub-path 1231 and the fourth sub-path 1232 are located on both sides of the first blocking portion 13.

[0041] The heat exchanger core 1 includes a second blocking portion 14, which is located in the first fluid path 121. The first fluid path 121 includes a first sub-path 1211 and a second sub-path 1212. The first sub-path 1211 is connected to the inner cavity of the drainage tube 3, and the second sub-path 1212 is located outside the drainage tube 3; the second blocking portion 14 separates the first sub-path 1211 and the second sub-path 1212.

[0042] The inter-plate path 122 includes at least a first heat exchange zone 1221, a second heat exchange zone 1222 and a third heat exchange zone 1223, the first sub-path 1211 is connected to the first heat exchange zone 1221, the first heat exchange zone 1221 is connected to the third sub-path 1231, the third sub-path 1231 is connected to the second heat exchange zone 1222, the second heat exchange zone 1222 is connected to the second sub-path 1212, and the second sub-path 1212 is connected to the third heat exchange zone 1223.

[0043] The top plate 113 of the heat exchanger core 1 is shown in FIG. Figure 8The top plate 113 of the heat exchanger core 1 includes a first orifice 113a, a second orifice 113b, a third orifice 113c, a fourth orifice 113d, and a fifth orifice 113e. The first orifice 113a is used to form a first fluid path 121, and the second orifice 113b is used to form a second fluid path 123. The third orifice 113c is connected to the second cavity 212, and the fourth orifice 113d and the fifth orifice 113e are connected to the second flow channel. The fluids in the first flow channel 12 and the second flow channel exchange heat inside the heat exchanger core.

[0044] The middle plate 114 of the heat exchanger core 1 comprises a first type of plate 1141 and a second type of plate 1142. The first type of plate 1141 of the heat exchanger core 1 is referred to as Figure 9 , the second type plate 1142 of the heat exchanger core 1 refers to Figure 10 As an example, the first type of plate 1141 of the heat exchanger core 1 includes a first orifice 1141a, a second orifice 1141b, a third orifice 1141c, a fourth orifice 1141d, and a fifth orifice 1141e. The first orifice 1141a, the second orifice 1141b, the fourth orifice 1141d, and the fifth orifice 1141e are located near the edges of the plate. The third orifice 1141c is located near the center of the plate relative to the first orifice 1141a and the second orifice 1141b. Along the length of the plate, the third orifice 1141c is located between the first orifice 1141a and the second orifice 1141b. The third orifice 1141c is used to form the third fluid path 1224, and a sensor can be inserted into the third orifice 1141c.

[0045] The first type of plate 1141 has multiple first plates 1144 and multiple second plates 1145. The first plates 1144 and the second plates 1145 are stacked on each other to form an inter-plate path 122. The first plate 1144 has a first step portion 1146a around the first orifice 1141a, and the first step portion 1146a protrudes relative to the plate plane 1147 of the first plate 1144. The first plate 1144 has a second step portion 1146b around the second orifice 1141b, and the second step portion 1146b protrudes relative to the plate plane 1147 of the first plate 1144. The first plate 1144 has a third step portion 1146c around the third orifice 1141c, and the third step portion 1146c protrudes relative to the plate plane 1147 of the first plate 1144. The fluid flowing through the first, second and third orifices is the same fluid. The third step 1146c is the same height as the first step 1146a, and the third step 1146c is the same height as the second step 1146b. Thus, after the plates are stacked, the third, second, and first steps can respectively isolate the first, second, and third orifices from the plate plane fluid path. Since the sensor will be inserted into the third orifice, there are certain requirements for sealing around the third orifice. If a leak occurs, the entire heat exchange assembly will fail. Therefore, a third step is provided around the third orifice at the same height as the first and second orifices. The third step is welded to the adjacent plate structure, effectively solving the sealing problem. The structure around the fourth orifice of the first plate is similar to that around the fifth orifice of the first plate, and the fluid flowing through the fourth and fifth orifices is the same fluid.

[0046] A first concave ring 1148a is arranged around the first orifice 1141a of the second plate 1145 of the first type plate 1141, a second concave ring 1148b is arranged around the second orifice 1141b, and a third concave ring 1148c is arranged around the third orifice 1141c. The concave ring structure of the second plate 1145 cooperates with the step structure of the first plate 1144 to form isolation of the flow channel.

[0047] The second type of plate 1142 of the heat exchanger core has multiple first plates, multiple second plates, and multiple third plates. The first plate of the second type of plate includes a first orifice 1142a, a second orifice 1142b, a fourth orifice 1142d, and a fifth orifice 1142e. The second plate of the second type of plate includes a first orifice 1142a, a second orifice 1142b, a fourth orifice 1142d, and a fifth orifice 1142e. The third plate of the second type of plate includes a first stop and a first orifice. The first stop is located at a position corresponding to the second orifice of the first plate, the second plate, and the fourth plate of the second type of plate; the first orifice 1142a, the second orifice 1142b, the fourth orifice 1142d, and the fifth orifice 1142e are located adjacent to the edge of the plate. The second type of plate has a similar plate structure to that used in the plate heat exchanger and will not be repeated here.

[0048] The first orifice 1141a of the first plate 1141 is aligned with the first orifice 1142a of the second plate 1142, forming a portion of the first fluid path. The third orifice 113c of the top plate 113 is no smaller than the first orifice 1141a of the first plate 1141, and the first orifice 1141a of the first plate 1141 is no smaller than the first orifice 1142a of the second plate 1142. The outer diameter of the port portion 2131 is smaller than the first orifice 1141a of the first plate 1141, and larger than the first orifice 1142a of the second plate 1142. The second side portion of the valve body 21 is welded to the periphery of the top plate where the third orifice is located, achieving a seal at the third orifice of the first plate.

[0049] The drainage tube 3 comprises an extension portion 31 and a main portion 32. The extension portion 31 has a larger outer diameter than the main portion 32, while the main portion 32 has an outer diameter no larger than the first opening 1142a of the second-type plate 1142. The main portion 32 extends into the first opening 1142a of the second-type plate 1142. The extension portion 31 has an outer diameter larger than the first opening 1142a of the second-type plate 1142. The extension portion 31 can be hung on the second-type plate 1142 and welded to the second-type plate 1142, sealing the connection between the first opening 1141a of the first-type plate 1141 and the first opening 1142a of the second-type plate 1142. The extension portion 31 of the drainage tube 3 can be welded to the port portion 2131 of the insertion portion 213, helping to separate the fluid channels on both sides of the extension portion 31. The setting of the drainage pipe 3 can guide the fluid in the throttling outlet channel of the valve core component connected to the drainage pipe 3 to the first sub-path, so that the fluid enters the inter-plate path from the first sub-path, which helps the fluid to exchange heat more evenly in the inter-plate path and improve the heat exchange efficiency.

[0050] The main body 32 has a bottom end portion 321, and the bottom end portion 321 is welded and fixed to at least one of the second type plates 1142. As an embodiment, at least one of the second type plates 1142 has an extension body 1143, and the extension body 1143 is located at the periphery of the first orifice 1142a of the second type plate 1142, and the outer wall of the bottom end portion 321 is welded and fixed to the wall of the extension body 1143. The bottom end portion 321 is welded and fixed to the extension body 1143, which helps to isolate the inner cavity of the drainage tube 3 from the outer cavity of the drainage tube 3 and helps to guide the flow direction of the fluid. As another embodiment, the bottom end portion 321 of the drainage tube 3 has an extension body, which extends out of the periphery of the bottom end portion, and the extension body of the drainage tube is welded and fixed to at least one of the second type plates.

[0051] The first stopper 13 can be a part of one of the second type plates 1142, or it can be a separate structure. As an embodiment, one of the second type plates 1142 has a first stopper, and the first stopper 13 is located at the second orifice position of the plate, and the first stopper can separate the fluid paths on both sides. The first stopper 13 can be implemented, for example, by not stamping the second orifice position of this plate of the second type plate 1142. As another embodiment, the first stopper 13 can be a separate plate-like structure, which closes the second orifice of one of the second type plates 1142, and the first stopper 13 can be welded and fixed to the adjacent plate. To increase strength, the thickness of the first stopper 13 can be greater than that of the second type plate 1142. As another embodiment, the first stopper 13 can also have a first sheet and a second sheet, the first sheet is integrally arranged with one of the second type plates, which is obtained by not stamping the second orifice position of the second type plate 1142, and the second sheet is welded and fixed to the first sheet, and the second sheet is located on the side of the first sheet facing the top plate. The second sheet portion can be used to enhance the strength of the first sheet portion, so as to facilitate the first sheet portion in resisting the impact of the fluid in the third sub-path.

[0052] The heat exchanger core has a third fluid path 1224 that communicates with the second cavity 212. A sensor 23 extends into this third fluid path 1224. In the direction of plate stacking, the third fluid path 1224 extends deeper into the heat exchanger core 1 than the extending portion 213 does. This allows fluid entering the third heat exchange zone 1223 from the second sub-path 1212 to enter the third fluid path 1224. The sensor 23, which extends into the third fluid path 1224, detects the fluid's temperature and / or pressure, which is then fed back to the valve assembly 2 to control flow regulation within the valve assembly 2.

[0053] The valve assembly 2 includes a circuit board 24 , which is electrically connected to the sensor. The valve assembly includes a valve needle, and the circuit board controls some structures of the valve assembly to drive the valve needle to move.

[0054] The valve assembly 2 can be coaxially arranged with the first fluid path 121, and the sensor 23 can be arranged in parallel with the valve assembly 2, which is helpful for accurate control of the valve.

[0055] The refrigerant enters the drainage pipe 3 through the throttling expansion of the valve core component 22 and evaporates in the heat exchanger core 1. The refrigerant will exist in a gas-liquid two-phase state. In order to improve the fluid heat exchange in each heat exchange zone, in the stacking direction of the plates, the height of the first heat exchange zone 1221 is smaller than the height of the second heat exchange zone 1222, and the height of the second heat exchange zone 1222 is smaller than the height of the third heat exchange zone 1223.

[0056] The valve body 21 has a main part 218 and an outer edge part 219. The main part 218 is located in the heat exchanger core 1. The projection of the main part 218 in the stacking direction of the plate is located on the plate. The outer edge part 219 extends out of the heat exchanger core. The outer edge part 219 can be used to limit and fix the valve core component.

[0103] The valve body 21" has a first interface and a second interface. The first interface can be used as a fluid inlet, and the second interface can be used as a fluid outlet. After the fluid enters from the first interface, it passes through the throttling inlet channel, the throttling port, and the throttling outlet channel of the valve core component, enters the third fluid path, the first heat exchange area, the first sub-path, the second heat exchange area, the third sub-path, the third heat exchange area, the second sub-path, the fourth heat exchange area, and the second cavity, and leaves from the second interface. When the heat exchange component is used as an evaporator, the fluid evaporates and absorbs heat inside the heat exchanger after passing through the throttling and pressure reduction of the valve core component. When the second chamber is in operation, the sensor acquires its temperature and / or pressure information, which is then fed back to the valve core component's circuit board, allowing the valve core component to be adjusted in a timely manner. This allows for accurate and rapid adjustment of the valve core component, making it easier to adjust the superheat of the fluid at the heat exchange component outlet and more conducive to the performance stability of the system connected to the heat exchange component. Furthermore, the provision of the first and second stoppers within the heat exchange core allows for a multi-flow design within the heat exchange core, which helps ensure more uniform heat exchange within the heat exchanger and improves heat exchange efficiency.
