[0041] Deformation rib, which is located between the receiving groove and the deformation groove;

[0042] Press the refrigerant pipe so that the refrigerant pipe fits with the receiving groove, and bend the deformation rib towards the refrigerant pipe so that the deformation rib contacts the refrigerant pipe.

[0043] The above technical solution can achieve the following technical effects: By pressing the refrigerant pipe in the first direction with an external force, the inner peripheral surface of the refrigerant pipe is closely attached to the inner peripheral surface of the receiving groove, which can ensure the matching strength between the refrigerant pipe and the receiving groove after the refrigerant pipe is pressed. Bend the deformation rib towards the refrigerant pipe so that the deformation rib contacts the refrigerant pipe. The contact between the deformation rib and the refrigerant pipe can prevent the refrigerant pipe from disengaging from the receiving groove. The operation is simple, and the installation efficiency of the refrigerant pipe and the second heat dissipation plate can be improved.

[0044] In some embodiments of the present application, the refrigerant pipe includes:

[0045] The straight pipe sections are arranged in the accommodation grooves, and the number of the straight pipe sections corresponds to the number of the accommodation grooves;

[0046] The bent pipe sections communicate with two adjacent straight pipe sections, and the bent pipe sections are arranged outside the accommodation grooves;

[0047] The second heat dissipation plate includes at least two of the accommodation grooves, and the at least two accommodation grooves are arranged side by side, and the refrigerant pipe penetrates through the two accommodation grooves;

[0048] Define the depth direction of the accommodation groove as the first direction;

[0049] The outer diameter length of the bent pipe section is A2, and the maximum dimension of the deformation rib in the width direction is G2, and G2 / A2≥0.1 and G2 / A2≤0.5.

[0050] The above technical solution can achieve the following technical effects: G2 / A2≥0.1 can ensure that the width of the deformation rib is not too small relative to the outer diameter of the refrigerant pipe, which can guarantee the strength of the deformation rib after it abuts against the refrigerant pipe and avoid the problem that the deformation rib is not strong enough to limit the refrigerant pipe in the accommodation groove. G2 / A2≤0.5 can avoid the problem that the deformation rib is not easy to bend due to its too large size and prevent the problem that the size of the deformation rib is too large resulting in the too large size of the second heat dissipation plate in the second direction.

[0051] In some embodiments of the present application, the deformation groove corresponding to the deformation rib is arranged on the side of the deformation rib away from the accommodation groove, and the deformation groove is recessed into the interior of the second heat dissipation plate, so as to apply an external force to the deformation rib in the deformation groove, so as to facilitate bending the deformation rib, and further facilitate restricting the refrigerant pipe in the accommodation groove.

[0052] In some embodiments of the present application, the maximum dimension of the deformation groove in the depth direction is I2, and I2 / A2≥0.1 and I2 / A2≤0.5.

[0053] The above technical solution can achieve the following technical effects: I2 / A2≥0.1 can ensure that the deformation rib has enough size in the first direction for bending, so as to facilitate the deformed rib to limit the refrigerant pipe and prevent the refrigerant pipe from disengaging from the accommodation groove. I2 / A2≤0.5 can ensure that the depth dimension of the deformation rib is not too long, avoid the problem that the depth dimension of the deformation rib affects the structural strength of the wall surface of the accommodation groove, and can ensure that the structural strength of the second heat dissipation plate can support the refrigerant pipe after the refrigerant pipe is pressed into the accommodation groove, and prevent the second heat dissipation plate from being deformed by the extrusion of the refrigerant pipe.

[0054] In some embodiments of the present application, the deformation groove includes:

[0055] The first pressing surface forms the side wall surface of the deformation groove, and the first pressing surface forms the side wall surface of the deformation rib away from the receiving groove;

[0056] The second pressing surface forms the other side wall surface of the deformation groove. The second pressing surface is connected to the first pressing surface to form a first included angle J2. The opening direction of the first included angle J2 faces away from the refrigerant radiator, 15° ≤ J2 ≤ 60°.

[0057] The above technical solution can achieve the following technical effects: Since 15° ≤ J2, it can ensure that there is an appropriate included angle between the first pressing surface and the second pressing surface, which is convenient for extruding the deformation rib in the deformation groove by an external force, so as to facilitate the deformation of the deformation rib. The deformation rib bends towards the refrigerant pipe and contacts the refrigerant pipe. The bent deformation rib can prevent the refrigerant pipe from disengaging from the receiving groove. Since J2 ≤ 60°, it can ensure that the first included angle between the first pressing surface and the second pressing surface is not too large, avoiding affecting the structural strength of the wall surface of the receiving groove due to the too large first included angle. After the refrigerant pipe is pressed into the receiving groove, it can ensure that the structural strength of the second heat dissipation plate can support the refrigerant pipe and prevent the second heat dissipation plate from deforming due to the extrusion of the refrigerant pipe.

[0058] In some embodiments of the present application, the deformation groove includes:

[0059] The first pressing surface forms the side wall surface of the deformation groove, and the first pressing surface forms the side wall surface of the deformation rib away from the receiving groove;

[0060] The second pressing surface forms the other side wall surface of the deformation groove. The second pressing surface is arranged opposite to the first pressing surface;

[0061] The third pressing surface is arranged at the bottom of the deformation groove and connects the first pressing surface and the second pressing surface respectively.

[0062] The above technical solution can achieve the following technical effects: In this embodiment, it is convenient to extrude the first pressing surface in the deformation groove. Extruding the first pressing surface makes the deformation rib bend towards the refrigerant pipe to limit the shaking of the refrigerant pipe in the receiving groove and avoid the refrigerant pipe disengaging from the receiving groove.

[0063] In some embodiments of the present application, after bending the deformation rib towards the refrigerant pipe so that the deformation rib contacts the refrigerant pipe, the included angle between the plane where the first pressing surface is located and the first direction is a second included angle K2, 30° ≤ K2 ≤ 60°.

[0064] The above technical solution can achieve the following technical effects: K2 ≥ 30°, which can ensure that the deformed rib bends a certain angle towards the direction close to the refrigerant pipe, ensuring that the deformed rib can effectively restrict the refrigerant in the receiving groove and prevent the refrigerant pipe from disengaging from the receiving groove. K2 ≤ 60°, which can ensure that the angle at which the deformed rib bends towards the direction close to the refrigerant pipe is not too large, avoiding the problem of fracture at the connection between the deformed rib and the second heat dissipation plate due to bending.

[0065] In some embodiments of the present application, the maximum dimension of the deformation groove in the width direction is H2, and H2 / A2 ≥ 0.1, H2 / A2 ≤ 0.5.

[0066] The above technical solution can achieve the following technical effects: H2 / A2 ≥ 0.1 can ensure that the width of the deformation groove in the second direction is not too small, facilitating the bending of the deformed rib by an external force, thereby improving the bending efficiency of the deformed rib and the assembly efficiency of the refrigerant pipe and the second heat dissipation plate. H2 / A2 ≤ 0.5 can ensure that the width of the deformation groove in the second direction is not too large, reducing the space occupied by the deformation groove in the second direction of the second heat dissipation plate, which is beneficial to reducing the size of the second heat dissipation plate, saving the cost of the second heat dissipation plate, and making the second heat dissipation plate smaller to reduce space occupation.

[0067] In some embodiments of the present application, the outer diameter length of the bent pipe section is A2, and A2 ≥ 7, A2 ≤ 12.7.

[0068] The above technical solution can achieve the following technical effects: A2 ≥ 7 can ensure that the size of the refrigerant pipe is not too small, avoiding the problem that the diameter of the refrigerant pipe is too small to play a throttling role. A2 ≤ 12.7 can ensure that the size of the refrigerant pipe is not too large, facilitating the general assembly of the refrigerant pipe.

[0069] Additional aspects and advantages of the present utility model will be partially given in the following description, partially become apparent from the following description, or be understood through the practice of the present utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0086] Next, some embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present disclosure.

[0087] This embodiment provides an air conditioner outdoor unit, which will be described below with reference to Figures 1 - 15 to describe the air conditioner outdoor unit.

[0088] The air conditioner outdoor unit 200 is a component of the air conditioner 1000. Among them, the air conditioner 1000 further includes an air conditioner indoor unit 100.

[0089] Referring to Figures 1 - 15 , the air conditioner 1000 may include an air conditioner indoor unit 100 and an air conditioner outdoor unit 200. The air conditioner indoor unit 100 is installed in an indoor space. The air conditioner outdoor unit 200 is installed in an outdoor space for heat exchange with the outdoor environment.

[0090] The air conditioner indoor unit can be a wall-mounted air conditioner indoor unit or a floor-standing air conditioner indoor unit. In this application, a wall-mounted air conditioner indoor unit is taken as an example for elaboration.

[0091] Referring to Figure 3 , the air conditioner indoor unit 100 includes a main body 300. The main body 300 has a bottom and a top. The direction from the bottom to the top of the main body 300 is the height direction of the main body 300. The main body 300 also has a length direction. Among them, the direction from one side to the other side of the main body 300 in the left-right direction is the length direction of the main body 300. The main body 300 has a front side and a rear side that are oppositely arranged. Among them, the side of the main body 300 facing the user is the front side of the main body 300. The direction from the front side to the rear side of the main body 300 is the front-rear direction of the main body 300.

[0092] The main body 300 may include a housing 3 disposed in an indoor space. The housing 3 has a front side and a rear side disposed opposite to each other, and the side of the housing 3 facing the user is the front side of the housing 3.

[0093] The main body 300 may include a heat exchange air inlet 31 disposed at the top of the housing 3. When cooling or heating, indoor air can enter the interior of the housing 3 through the heat exchange air inlet 31.

[0094] The main body 300 may include a first chamber formed inside the housing 3. The first chamber is in communication with the heat exchange air inlet 31, and indoor air can enter the first chamber through the heat exchange air inlet 31.

[0095] The main body 300 may include a heat exchange air outlet 32 disposed at the bottom of the housing 3. The first chamber is in communication with the heat exchange air inlet 31 and the heat exchange air outlet 32 respectively. When cooling or heating, indoor air flows from the heat exchange air inlet 31 to the first chamber, and then flows to the interior through the heat exchange air outlet 32.

[0096] The main body 300 may include an indoor heat exchanger 1001 disposed in the first chamber. The indoor heat exchanger 1001 is configured to exchange heat with the indoor air entering the first chamber.

[0097] In some embodiments, the main body 300 may include a base disposed in the first chamber, and a heat exchange air duct is formed inside the base.

[0098] In some embodiments, the main body 300 may include a heat exchange fan disposed in the heat exchange air duct. The axial direction of the heat exchange fan is the same as the length direction of the main body 300. By operating the heat exchange fan, indoor air is introduced from the heat exchange air inlet into the first chamber, then flows through the indoor heat exchanger 1001, and after flowing through the heat exchange air duct, it flows to the interior through the heat exchange air outlet 32.

[0099] Optionally, the heat exchange fan is disposed on the leeward side of the indoor heat exchanger 1001 to reduce the resistance of the indoor heat exchanger 1001 to air flow and increase the air intake into the interior.

[0100] Refer to Figures 4 - 15 , in some embodiments, an air conditioner outdoor unit 200 is disposed in an outdoor space. The air conditioner outdoor unit 200 includes a housing, and the housing constitutes the external structure of the air conditioner outdoor unit. A receiving cavity is provided inside the housing 21.

[0101] In some embodiments, the air conditioner outdoor unit may include a partition 22 disposed in the receiving cavity. The partition 22 divides the receiving cavity into a first chamber 211 and a second chamber 212, and the first chamber 211 and the second chamber 212 are arranged in parallel.

[0102] In some embodiments, the first chamber 211 and the second chamber 212 may communicate with each other.

[0103] In some embodiments, the housing 21 may include an outdoor air inlet and an outdoor air outlet. The housing 21 has a front side and a rear side that are oppositely arranged. The outdoor air outlet is provided on the front side of the housing 21, and the outdoor air inlet is provided on the rear side of the housing 21. The outdoor air inlet is in communication with the outdoor space and the second chamber 212, and the outdoor air outlet is in communication with the outdoor space and the second chamber 212. The housing 21 has a bottom and a top, and the height direction of the housing 21 is from the bottom of the housing 21 to the top of the housing 21.

[0104] In some embodiments, the air conditioner outdoor unit may include a compressor 201. The compressor 201 is disposed in the first chamber and is installed at the bottom of the air conditioner outdoor unit.

[0105] In some embodiments, the air conditioner outdoor unit may include an outdoor heat exchanger 202. A refrigerant circuit is provided between the compressor, the outdoor heat exchanger, and the indoor heat exchanger. A refrigerant flows through the indoor heat exchanger, the outdoor heat exchanger, and the refrigerant circuit. The refrigerant circuit is sequentially connected to the compressor, the outdoor heat exchanger, and the indoor heat exchanger. The refrigerant can flow through the compressor, the outdoor heat exchanger, and the indoor heat exchanger and then flow back into the compressor. The refrigerant can be used to exchange heat with the air that enters the second chamber and flows through the outdoor heat exchanger 202.

[0106] In some embodiments, the air conditioner outdoor unit may include an outdoor heat exchange fan. The outdoor heat exchange fan is disposed in the second chamber, and drives outdoor air to enter the interior of the housing. After the air exchanges heat with the outdoor heat exchanger, it is blown outdoors.

[0107] In some embodiments, the air conditioner outdoor unit 200 may include a throttling device 204. The throttling device 204 is disposed in the first chamber and is used to expand the high-temperature and high-pressure liquid-phase refrigerant into a low-pressure liquid-phase refrigerant.

[0108] The throttling device 204 may be disposed on the leeward side of the outdoor heat exchanger 202, which is convenient for connection to the compressor 201.

[0109] The air conditioner 1000 performs the refrigeration cycle of the air conditioner 1000 by using the compressor 201, the outdoor heat exchanger 202, the throttling device 204, and the indoor heat exchanger 1001. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies the refrigerant to the air that has been conditioned and heat-exchanged.

[0110] The compressor 201 compresses the refrigerant gas in the low-temperature and low-pressure state and discharges the refrigerant gas in the high-temperature and high-pressure state. The discharged refrigerant gas flows into the outdoor heat exchanger 202.

[0111] The outdoor heat exchanger 202 condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0112] The throttling device 204 expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the outdoor heat exchanger 202 into a low-pressure liquid-phase refrigerant.

[0113] The indoor heat exchanger 1001 evaporates the refrigerant expanded in the throttling device 204 and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor 201.

[0114] The indoor heat exchanger 1001 can achieve a refrigeration effect by exchanging heat with the material to be cooled by utilizing the latent heat of evaporation of the refrigerant. During the entire cycle, the air conditioner 1000 can adjust the temperature of the indoor space.

[0115] In both the indoor heat exchanger 1001 and the outdoor heat exchanger 202, one of them is a condenser and the other is an evaporator. When the indoor heat exchanger 1001 is used as a condenser and the outdoor heat exchanger 202 is used as an evaporator, the air conditioner 1000 serves as a heater in the heating mode. When the indoor heat exchanger 1001 is used as an evaporator and the outdoor heat exchanger 202 is used as a condenser, the air conditioner 1000 serves as a cooler in the cooling mode.

[0116] In some embodiments, the outdoor unit 200 of the air conditioner may include an electrical component box, and at least part of the electrical component box is disposed in the first chamber 211.

[0120] ″Parallel″ includes absolute parallel and approximate parallel, and the acceptable deviation range of approximate parallel may be, for example, within 5°.

[0121] In some embodiments, the plane where the circuit board body 25 is located is vertically arranged. The circuit board can be arranged in a large-sized housing 21. Since the size of the housing 21 is large, the circuit board can be entirely arranged in the first chamber 211 without significantly affecting the space occupancy of the first chamber 211. The circuit board body 25 can be arranged according to the size structure of the air conditioner outdoor unit.

[0122] ″Vertically″ includes absolute vertical and approximate vertical. The acceptable deviation range of approximate vertical can be, for example, within 5°.

[0124] In some embodiments, the circuit board may include a power module 26. The power module 26 is arranged on the circuit board and is connected to the circuit board body 25 by soldering.

[0125] The power module 26 can be set as an IGBT power module 26. The IGBT power module 26 generates a certain amount of heat during operation. On the circuit board body 25, the IGBT power module 26 is one of the main heat sources. To ensure the normal operation and reliability of the circuit board body 25, heat dissipation measures need to be taken for the power module 26.

[0126] In some embodiments, the power module 26 has a chip, and the periphery of the chip is wrapped with a plastic package.

The module support 51 is used to support the power module 26, which can prevent the solder feet connecting the power module 26 to the circuit board body from being stressed and damaged, thereby avoiding damage to the power module 26.

[0130] In some embodiments, the air conditioner outdoor unit may include a refrigerant radiator 208. The refrigerant radiator 208 is arranged in the first chamber. The refrigerant radiator 208 is used for dissipating heat from the power module.

[0131] In some embodiments, the refrigerant radiator 208 may include a first heat dissipation plate 24 disposed on a side of the power module 26 away from the circuit board body 25, and the first heat dissipation plate 24 is in contact with the power module 26.

[0132] In some embodiments, the refrigerant radiator 208 may include a second heat dissipation plate 28 connected to the first heat dissipation plate 24.

[0133] The second heat dissipation plate 28 may include a receiving groove 284 disposed on a side of the second heat dissipation plate 28 away from the first heat dissipation plate 24, and the receiving groove 284 is recessed into the interior of the second heat dissipation plate 28.

[0134] In some embodiments, the refrigerant radiator 208 may include a refrigerant pipe 29 disposed in the receiving groove 284, and the refrigerant pipe 29 communicates with the refrigerant circuit.

[0135] The receiving groove 284 has an opening 2841 on the second heat dissipation plate 28. When assembling the refrigerant pipe 29 and the receiving groove 284, the refrigerant pipe 29 is placed into the receiving groove 284 through the opening 2841.

[0136] A side of the first heat dissipation plate 24 away from the power module 26 is in contact with the second heat dissipation plate 28. Heat generated by the power module 26 is transferred to the second heat dissipation plate 28 through the first heat dissipation plate 24, and then the heat is taken away through heat transfer with the refrigerant pipe 29, playing a role in dissipating heat from the power module 26.

[0137] In some embodiments, the second heat dissipation plate 28 may include a deformation groove 287 located on a side of the second heat dissipation plate away from the first heat dissipation plate. The deformation groove 287 corresponds to a deformation rib 286. The deformation groove 287 corresponding to the deformation rib 286 is disposed on a side of the deformation rib 286 away from the receiving groove 284, and the deformation groove 287 is recessed into the interior of the second heat dissipation plate 28 to facilitate applying an external force to the deformation rib 286 in the deformation groove 287, so as to facilitate bending the deformation rib 286 and further facilitate restricting the refrigerant pipe in the receiving groove 284.

[0138] In some embodiments, the deformation groove 287 may be set as a V-shaped groove or a square groove or other special-shaped grooves.

[0139] In some embodiments, deformation ribs 286 are respectively disposed on both sides of the receiving groove 284 in the second direction. A deformation groove 287 corresponding to the deformation rib 286 is disposed on a side of the deformation rib 286 away from the receiving groove 284, and the number of deformation grooves 287 corresponds to the number of deformation ribs 286 one by one.

[0140] In some embodiments, the second heat dissipation plate 28 may include a deformation rib 286. The deformation rib 286 is located between the accommodation groove 284 and the deformation groove 287, and the deformation rib 286 is provided at the edge of the opening. Bend the deformation rib 286 towards the refrigerant pipe so that the deformation rib 286 contacts the refrigerant pipe. At this time, the deformation rib 286 deforms, and the deformation rib 286 is used to limit the sway of the refrigerant pipe 29. The contact between the deformation rib 286 and the refrigerant pipe can limit the refrigerant pipe from disengaging from the accommodation groove 284.

[0141] By providing the deformation rib 286 in the present utility model, the refrigerant pipe arranged in the accommodation groove can be limited, preventing the refrigerant pipe from disengaging from the accommodation groove. The refrigerant pipe is arranged in the accommodation groove, and the deformation rib 286 is bent towards the refrigerant pipe so that the deformation rib 286 contacts the refrigerant pipe, making the installation of the refrigerant pipe and the second radiator convenient, improving the installation efficiency between the refrigerant pipe and the second heat dissipation plate, and preventing damage to the refrigerant pipe caused by pressing the refrigerant pipe.

[0142] In some embodiments, when assembling the refrigerant pipe and the second heat dissipation plate, the refrigerant pipe 29 is placed into the accommodation groove 284, and the refrigerant pipe 29 is pressed by a pipe pressing process so that the refrigerant pipe 29 deforms and presses towards both sides of the accommodation groove 284, making the refrigerant pipe 29 closely adhere to the inner peripheral surface of the accommodation groove 284 and making the refrigerant pipe 29 adapted to the accommodation groove 284. Bend the deformation rib 286 towards the refrigerant pipe so that the deformation rib 286 contacts the refrigerant pipe. At this time, the deformation rib 286 deforms, and the contact between the deformation rib 286 and the refrigerant pipe can limit the refrigerant pipe from disengaging from the accommodation groove.

[0143] Press the refrigerant pipe in the first direction by an external force so that the refrigerant pipe closely adheres to the inner peripheral surface of the accommodation groove, which can ensure the fitting strength between the refrigerant pipe 29 and the accommodation groove 284 after pressing the refrigerant pipe 29. Bend the deformation rib 286 towards the refrigerant pipe so that the deformation rib 286 contacts the refrigerant pipe. The contact between the deformation rib 286 and the refrigerant pipe can limit the refrigerant pipe from disengaging from the accommodation groove, with simple operation and improved installation efficiency of the refrigerant pipe and the second heat dissipation plate.

[0144] In some embodiments, the refrigerant pipe 29 may include a straight pipe section 291. The straight pipe section 291 is arranged in the accommodation groove 284, the number of the straight pipe sections 291 corresponds to the section of the accommodation groove 284, and the extending direction of the straight pipe section 291 is arranged in the same direction as the extending direction of the accommodation groove 284.

[0145] In some embodiments, the refrigerant pipe 29 may include a bent pipe section 292. The bent pipe section 292 connects two adjacent straight pipe sections 291, and the bent pipe section 292 is arranged outside the accommodation groove 284.

[0146] In some embodiments, the straight pipe section 291 and the bent pipe section 292 are integrally formed, and the bent pipe section 292 and the straight pipe section 291 are formed by bending the refrigerant pipe 29.

[0147] In some embodiments, the outer diameter of the straight pipe section 291 before pressing the pipe is the same as the outer diameter A2 of the bent pipe section 292.

[0148] In some embodiments, the second heat dissipation plate may include at least two receiving grooves 184, and the at least two receiving grooves 284 are arranged in parallel. One section of the refrigerant pipe 29 sequentially passes through the two receiving grooves 284 to be connected to the receiving grooves 284.

[0149] Define the depth direction of the receiving groove 284 as the first direction, and the direction in which the receiving grooves 284 are arranged in parallel as the second direction.

[0150] In some embodiments, the length of the outer diameter of the bent pipe section is A2, and the dimension of the deformation rib 286 in the width direction is G2, where G2 / A2≥0.1 and G2 / A2≤0.5.

[0151] G2 / A2 has a lower limit value, and G2 / A2 cannot be less than the lower limit value of G2 / A2. When G2 / A2 is less than the lower limit value of G2 / A2, the width of the deformation rib 286 relative to the outer diameter of the refrigerant pipe 29 is too small, resulting in a relatively low structural strength of the deformation rib 286 after it abuts against the refrigerant pipe 29. This may cause the deformation rib 286 to deform and be unable to restrict the refrigerant pipe 29 within the receiving groove 284. The lower limit value of G2 / A2 can be 0.1.

[0152] G2 / A2 has an upper limit value, and G2 / A2 cannot be greater than the upper limit value of G2 / A2. When G2 / A2 is greater than the upper limit value of G2 / A2, the width of the deformation rib 286 relative to the outer diameter of the refrigerant pipe 29 is too large, increasing the dimension of the deformation rib 286 in the second direction. This can cause problems such as the deformation rib 286 being inconvenient to bend due to its excessive size, making it inconvenient to fix the refrigerant pipe 29. It can also cause the problem that the size of the deformation rib 286 is too large, resulting in an excessive size of the second heat dissipation plate 28 in the second direction. The upper limit value of G2 / A2 can be 0.5.

[0153] The preferred value of G2 / A2 can be 0.3, which can make the width of the deformation rib 286 relative to the outer diameter of the refrigerant pipe 29 appropriate, ensuring the strength of the deformation rib 286 after it abuts against the refrigerant pipe 29. This can avoid the problem that the deformation rib 286 is not strong enough to restrict the refrigerant pipe 29 within the receiving groove 284, and can also avoid the problem that the deformation rib 286 is inconvenient to bend due to its excessive size. It can also prevent the problem that the size of the deformation rib 286 is too large, resulting in an excessive size of the second heat dissipation plate 28 in the second direction.

[0154] In some embodiments, in some embodiments, the width direction of the deformation groove is arranged in the same direction as the second direction, and the maximum dimension of the deformation groove 287 in the width direction is H2, where H2 / A2≥0.1 and H2 / A2≤0.5.

[0155] H2 / A2 has a lower limit value, and H2 / A2 cannot be less than the lower limit value of H2 / A2. When H2 / A2 is less than the lower limit value of H2 / A2, the width of the deformation groove 287 may be too small, which is not conducive to placing the tooling into the deformation groove 287, and is not conducive to external force acting on the deformation rib 286 for bending, resulting in low bending efficiency of the deformation rib 286, which is not conducive to the assembly efficiency of the refrigerant pipe 29 and the second heat sink 28. The lower limit value of H2 / A2 can be 0.1.

[0156] H2 / A2 has an upper limit value, and H2 / A2 cannot be greater than the upper limit value of H2 / A2. When H2 / A2 is greater than the upper limit value of H2 / A2, the width of the deformation groove 287 may be too large, which may increase the space occupied by the deformation groove 287 in the second direction of the second heat sink 28, resulting in a larger size of the second heat sink 28, and a higher cost of the second heat sink 28, resulting in waste. The upper limit value of H2 / A2 can be 0.5.

[0157] The preferred value of H2 / A2 is 0.3, which can prevent the width of the deformation groove 287 in the second direction from being too small, so that external force can act on the deformation rib 286 to bend it, thereby facilitating the improvement of the bending efficiency of the deformation rib 286 and the assembly efficiency of the refrigerant tube 29 and the second heat sink 28. It can also prevent the width of the deformation groove 287 in the second direction from being too large, thereby reducing the space occupied by the deformation groove 287 in the second direction of the second heat sink 28, which is beneficial to reducing the size of the second heat sink 28, saving the cost of the second heat sink 28, and making the second heat sink 28 smaller to reduce the space occupied.

[0158] In some embodiments, the maximum dimension of the deformation groove 287 in the depth direction is I2, I2 / A2≥0.1, 12 / A2≤0.5.

[0159] 12 / A2 has a lower limit value, and 12 / A2 cannot be less than the lower limit value of 12 / A2. When 12 / A2 is less than the lower limit value of 12 / A2, the depth of the deformation groove 287 will be too small. Since the deformation rib 286 is adjacent to the deformation groove 287, the deformation rib 286 forms the side wall surface of the deformation groove 287. The depth of the deformation groove 287 is too small, which may make the deformation rib 286 unable to limit the refrigerant pipe 29 after bending in the first direction, so that the refrigerant pipe can easily escape from the accommodating groove 284. The lower limit value of 12 / A2 can be 0.1.

[0160] 12 / A2 has an upper limit value, and 12 / A2 cannot be greater than its upper limit value. When 12 / A2 is greater than its upper limit value, the depth dimension of the deformed rib 286 will be too long. The overlong depth dimension of the deformed rib 286 will affect the structural strength of the wall surface of the receiving groove 284. After the refrigerant pipe 29 is pressed into the receiving groove 284, the structural strength of the second heat dissipation plate 28 may not be sufficient to support the refrigerant pipe 29, which may cause the second heat dissipation plate 28 to be deformed by the extrusion of the refrigerant pipe 29. The upper limit value of 12 / A2 can be 0.5.

[0161] The preferred value of 12 / A2 can be 0.3. On the one hand, it can prevent the depth of the deformation groove 287 from being too small. Since the deformed rib 286 and the deformation groove 287 are adjacent to each other, and the deformed rib 286 forms the side wall surface of the deformation groove 287, that is, 12 / A2 ≥ 0.1, it can enable the deformed rib 286 to have sufficient dimensions in the first direction for bending, so as to limit the refrigerant pipe 29 after bending and prevent the refrigerant pipe 29 from disengaging from the receiving groove 284. On the other hand, it can also prevent the depth dimension of the deformed rib 286 from being too long, avoiding the influence of the overlong depth dimension of the deformed rib 286 on the structural strength of the wall surface of the receiving groove 284. After the refrigerant pipe 29 is pressed into the receiving groove 284, it can ensure that the structural strength of the second heat dissipation plate 28 can support the refrigerant pipe 29 and prevent the second heat dissipation plate 28 from being deformed by the extrusion of the refrigerant pipe 29.

[0162] See Figures 13 - 15 , in some embodiments, the deformation groove 287 may include a first pressing surface 2871. The first pressing surface 2871 forms the side wall surface of the deformation groove 287, and the first pressing surface 2871 forms the side wall surface of the deformed rib 286 away from the receiving groove 284, that is, the deformed rib 286 is adjacent to the deformation groove 287, and the first pressing surface 2871 forms the side wall surface of the deformed rib 286 away from the receiving groove 284.

[0163] In some embodiments, the deformation groove 287 may include a second pressing surface 2872. The second pressing surface 2872 forms the other side wall surface of the deformation groove 287. The second pressing surface 2872 is disposed opposite to the first pressing surface 2871, and the second pressing surface 2872 is disposed away from the receiving groove 284 relative to the first pressing surface 2871.

[0164] In some embodiments, the second pressing surface 2872 is connected to the bottom of the first pressing surface 2871 to form a first included angle J2. The opening direction of the first included angle J2 faces away from the refrigerant radiator, 15° ≤ J2 ≤ 60°.

[0165] J2 has a lower limit value. J2 cannot be less than the lower limit value of J2. When J2 is less than the lower limit value of J2, the angle between the first pressing surface 2871 and the second pressing surface 2872 can be too small, making it inconvenient for the tooling to be placed into the deformation groove 287 to extrude and bend the deformation rib 286, which is not conducive to the positioning and installation of the refrigerant pipe 28. The lower limit value of J2 can be 15°.

[0166] J2 has an upper limit value. J2 cannot be greater than the upper limit value of J2. When J2 is greater than the upper limit value of J2, the first angle between the first pressing surface 2871 and the second pressing surface 2872 can be too large. An overly large first angle will affect the structural strength of the wall surface of the receiving groove 284. After the refrigerant pipe 29 is pressed into the receiving groove 284, the structural strength of the second heat dissipation plate 28 cannot support the refrigerant pipe 29, and the second heat dissipation plate 28 will be deformed due to the extrusion of the refrigerant pipe 29. The upper limit value of J2 can be 60°.

[0167] The preferred value of J2 can be 50°. On the one hand, it can ensure that there is a certain appropriate angle between the first pressing surface 2871 and the second pressing surface 2872, which is convenient for extruding the deformation rib 286 in the deformation groove 287 by an external force, so as to facilitate the deformation of the deformation rib 286. The deformation rib 286 bends towards the refrigerant pipe 29 and contacts the refrigerant pipe 29. The bent deformation rib 286 can prevent the refrigerant pipe 29 from disengaging from the receiving groove 284. On the other hand, it can ensure that the first angle between the first pressing surface 2871 and the second pressing surface 2872 is not too large, avoiding the influence on the structural strength of the wall surface of the receiving groove 284 due to the overly large first angle. After the refrigerant pipe 29 is pressed into the receiving groove 284, it can ensure that the structural strength of the second heat dissipation plate 28 can support the refrigerant pipe 29 and prevent the second heat dissipation plate 28 from being deformed due to the extrusion of the refrigerant pipe 29.

[0168] See Figures 8 - 10 In some embodiments, the deformation groove 287 may include a third pressing surface 2873. The third pressing surface 2873 is provided at the bottom in the depth direction of the deformation groove 287. The third pressing surface 2873 is respectively connected to the first pressing surface 2871 and the second pressing surface 2872. That is, the first pressing surface 2871 is connected to the second pressing surface 2872, and the second pressing surface 2872 is connected to the third pressing surface 2873. The opening of the deformation groove 287 faces away from the refrigerant radiator. The connection of the first pressing surface 2871, the second pressing surface 2872, and the third pressing surface 2873 can form a square groove, which is convenient for extruding the first pressing surface 2871 in the deformation groove 287. That is, by extruding the first pressing surface 2871, the deformation rib 286 is bent towards the refrigerant pipe 29 to limit the shaking of the refrigerant pipe 29 in the receiving groove 284 and prevent the refrigerant pipe 29 from disengaging from the receiving groove 284.

[0169] See Figures 8 - 15, in some embodiments, after bending the deformed rib 286 towards the refrigerant pipe 29 so that the deformed rib 286 contacts the refrigerant pipe 29, the angle between the plane where the first pressing surface 2871 is located and the first direction is the second angle K2≥30°, K2≤60°.

[0170] K2 has a lower limit value. K2 cannot be less than the lower limit value of K2. When K2 is less than the lower limit value of K2, the bending angle of the deformed rib 286 will be small, and the refrigerant pipe cannot be effectively restricted in the receiving groove 284. The lower limit value of K2 can be 30°.

[0171] K2 has an upper limit value. K2 cannot be greater than the upper limit value of K2. When K2 is greater than the upper limit value of K2, the angle at which the deformed rib 286 bends towards the refrigerant pipe 29 can be too large, which may cause the connection between the deformed rib 286 and the second heat dissipation plate 28 to break due to bending. The upper limit value of K2 can be 60°.

[0172] The preferred value of K2 can be 45°. On the one hand, it can ensure that the deformed rib 286 bends towards the refrigerant pipe 29 by a certain angle, ensuring that the deformed rib 286 can effectively restrict the refrigerant in the receiving groove 284 and prevent the refrigerant pipe 29 from disengaging from the receiving groove 284. On the other hand, it can make the angle at which the deformed rib 286 bends towards the refrigerant pipe 29 not too large, avoiding the problem that the connection between the deformed rib 286 and the second heat dissipation plate 28 breaks due to bending.

[0173] In some embodiments, after pressing the refrigerant pipe 29 into the receiving groove 284, in the first direction, the maximum distance between the side of the refrigerant pipe 29 away from the bottom of the receiving groove 284 and the bottom of the receiving groove 284 is L2, L2 < A2, which can cause the refrigerant pipe 29 to deform after being pressed in the depth direction of the receiving groove 284, facilitating the cooperation between the deformed refrigerant pipe 29 and the receiving groove 284. After the refrigerant pipe 29 deforms, the refrigerant pipe 29 is restricted in the receiving groove 284, preventing the refrigerant pipe 29 from disengaging from the connection with the receiving groove 284.

[0174] In some embodiments, the outer diameter length of the refrigerant pipe 29 before being pressed is the same as the outer diameter dimension of the bent pipe section. The outer diameter dimension of the bent pipe section is A2, A2≥7mm, A2≤12.7mm.

[0175] A2 has a lower limit value. A2 cannot be less than the lower limit value of A2. When A2 is less than the lower limit value of A2, the diameter of the refrigerant pipe needs to be customized and does not have universality. If the diameter of the refrigerant pipe 29 is too small, the refrigerant pipe cannot play a throttling role. The lower limit value of A2 can be 7mm.

[0176] A2 has an upper limit value. A2 cannot be greater than the upper limit value of A2. When A2 is greater than the upper limit value of A2, the diameter of the refrigerant pipe needs to be customized and does not have universality. If the diameter of the refrigerant pipe 29 is too large, the size of the refrigerant pipe will occupy a large space, which will further lead to an overly large size of the second heat dissipation plate. If the diameter of the refrigerant pipe 29 is too large, it will not be able to play an appropriate throttling role. The upper limit value of A2 can be 12.7 mm.

[0177] The preferred value of A2 can be 8 mm. On the one hand, it makes the diameter of the refrigerant pipe 29 meet the national standard metric size and the imperial size, which can ensure that the size of the refrigerant pipe 29 is not too small and can avoid the situation where the diameter of the refrigerant pipe 29 is too small to play a throttling role. On the other hand, 7 mm, 7.94 mm, 8 mm, 9.52 mm, 9.53 mm, 12 mm or 12.7 mm are the national standard metric size and the imperial size, which enables the diameter of the refrigerant pipe 29 to meet the national standard metric size and the imperial size, can ensure that the size of the refrigerant pipe 29 is not too large, and is convenient for the general assembly of the refrigerant pipe 29.

[0178] In some embodiments, the width of the opening of the receiving groove 284 is defined as B2. The outer diameter of the straight pipe section 291 before pipe pressing is the same as the outer diameter A2 of the bent pipe section 292, and B2 / A2 ≥ 1.03, B2 / A2 ≤ 1.15.

[0179] B2 / A2 has a lower limit value. B2 / A2 cannot be less than the lower limit value of B2 / A2. When B2 / A2 is less than the lower limit value of B2 / A2, the width of the opening of the receiving groove 284 can be too much smaller than the length of the outer diameter of the refrigerant pipe 29 before being pressed, so that the refrigerant cannot be directly put into the receiving groove 284 through the opening of the receiving groove 284, resulting in a low assembly efficiency of the refrigerant pipe 29 and the refrigerant pipe may be squeezed and cracked. The lower limit value of B2 / A2 can be 1.03.

[0180] B2 / A2 has an upper limit value. B2 / A2 cannot be greater than the upper limit value of B2 / A2. When B2 / A2 is greater than the upper limit value of B2 / A2, the width of the opening of the receiving groove 284 can be too large relative to the length of the outer diameter of the refrigerant pipe 29 before being pressed. After the refrigerant pipe 29 is pressed, the refrigerant pipe 29 will shake in the receiving groove 284, which is not conducive to restricting the refrigerant pipe in the receiving groove. The upper limit value of B2 / A2 can be 1.15.

[0181] The preferred value of B2 / A2 can be 1.11. On the one hand, it can prevent the width of the opening of the receiving groove 284 from being too much smaller than the outer diameter length of the refrigerant pipe 29 before being pressed, enabling the refrigerant heat dissipation pipe to be directly placed into the receiving groove 284 through the opening of the receiving groove 284, avoiding the problem that the refrigerant pipe 29 cannot pass through the receiving groove 284 along the length extension direction of the receiving groove 284. Even if the refrigerant pipe 29 is deformed and bent, it can still be placed into the receiving groove 284, improving the assembly efficiency of the refrigerant pipe 29 and the receiving groove 284, and ensuring the fitting strength between the refrigerant pipe 29 and the receiving groove 284 after pressing the refrigerant pipe 29. On the other hand, it can prevent the width of the opening of the receiving groove 284 from being too large relative to the outer diameter length of the refrigerant pipe 29 before being pressed, ensuring the fitting strength between the refrigerant pipe 29 and the receiving groove 284 after the refrigerant pipe 29 is pressed and preventing the refrigerant pipe 29 from disengaging from the receiving groove 284.

[0182] In some embodiments, the second heat dissipation plate 28 includes at least two receiving grooves 284, and the distance between the centers of two adjacent receiving grooves 284 is C2, where C2 / A2 ≥ 1 and C2 / A2 ≤ 10.

[0183] C2 / A2 has a lower limit value, and C2 / A2 cannot be less than the lower limit value of C2 / A2. When C2 / A2 is less than the lower limit value of C2 / A2, the distance between two adjacent receiving grooves 284 can be made too small, and the bending process of the refrigerant pipe cannot meet this spacing, making it inconvenient to place the bent refrigerant pipe 29 into two adjacent receiving grooves 284. The lower limit value of C2 / A2 can be 1.

[0184] C2 / A2 has an upper limit value, and C2 / A2 cannot be greater than the upper limit value of C2 / A2. When C2 / A2 is greater than the upper limit value of C2 / A2, the distance between two adjacent receiving grooves 284 can be made too large, resulting in too large a space size occupied by the second heat dissipation plate 28. It can also make the distance between adjacent refrigerant pipes 29 too large, reducing the heat dissipation effect of the refrigerant radiator and unable to effectively dissipate heat from the power module. The upper limit value of C2 / A2 can be 10.

[0185] The preferred value of C2 / A2 can be 5. On the one hand, it can prevent the distance between two adjacent receiving grooves 284 from being too small, ensuring that the bent refrigerant pipe 29 can be smoothly placed into two adjacent receiving grooves 284. On the other hand, it can prevent the distance between two adjacent receiving grooves 284 from being too large, preventing the space size occupied by the second heat dissipation plate 28 from being too large and also preventing the distance between adjacent refrigerant pipes 29 from being too large, thereby improving the heat dissipation effect of the refrigerant radiator.

[0186] In some embodiments, in the width direction of the receiving groove 284, the shortest distance from the opening 2841 of the receiving groove 284 to the edge of the second heat dissipation plate 28 is defined as D2, and D2 / A2 ≥ 0.25 and D2 / A2 ≤ 0.5.

[0187] D2 / A2 has a lower limit value, and D2 / A2 cannot be less than the lower limit value of D2 / A2. When D2 / A2 is less than the lower limit value of D2 / A2, the shortest distance D2 from the opening 2841 of the receiving groove 284 to the edge of the second heat dissipation plate 28 is too small, such that when the refrigerant pipe 29 is pressed into the receiving groove 284, the strength of the portion of the size D2 of the second heat dissipation plate 28 is small, and the second heat dissipation plate 28 is deformed by the force, and then the portion of the size D2 of the second heat dissipation plate 28 is deformed, which will affect the matching effect between the refrigerant pipe 29 and the receiving groove 284 and the heat dissipation effect. The lower limit value of D2 / A2 can be 0.25.

[0188] D2 / A2 has an upper limit value, and D2 / A2 cannot be greater than the upper limit value of D2 / A2. When D2 / A2 is greater than the upper limit value of D2 / A2, the shortest distance D2 from the opening 2841 of the receiving groove 284 to the edge of the second heat dissipation plate 28 is too large, such that the spatial size occupied by the second heat dissipation plate 28 is too large, which will reduce the effect of the refrigerant radiator and cannot effectively dissipate heat from the power module. The upper limit value of D2 / A2 can be 0.5.

[0189] The preferred value of D2 / A2 can be 0.3, which can make the shortest distance D2 from the opening 2841 of the receiving groove 284 to the edge of the second heat dissipation plate 28 appropriate. When the refrigerant pipe 29 is pressed into the receiving groove 284, the portion of the size D2 of the second heat dissipation plate 28 can have sufficient strength to prevent the deformation of the second heat dissipation plate 28, so as to ensure that the portion of the size D2 of the second heat dissipation plate 28 does not deform, and improve the matching effect between the refrigerant pipe 29 and the receiving groove 284 and the heat dissipation effect.

[0190] In some embodiments, the depth direction of the receiving groove 284 is defined as the first direction. In the depth direction of the receiving groove 284, the shortest distance from the bottom of the receiving groove 284 to the bottom of the second heat dissipation plate 28 is defined as E2, and E2 / A2 ≥ 0.25 and E2 / A2 ≤ 0.5.

[0191] E2 / A2 has a lower limit value. E2 / A2 cannot be less than the lower limit value of E2 / A2. When E2 / A2 is less than the lower limit value of E2 / A2, the shortest distance E2 from the bottom of the receiving groove 284 to the bottom of the second heat dissipation plate 28 is too small. When the refrigerant pipe 29 is pressed into the receiving groove 284, the second heat dissipation plate 28 is squeezed by the refrigerant pipe, and the dimension E2 part of the second heat dissipation plate 28 does not have sufficient strength to prevent the deformation of the second heat dissipation plate 28, which will cause the dimension E2 part of the second heat dissipation plate 28 to deform, affecting the matching effect between the refrigerant pipe 29 and the receiving groove 284 and the heat dissipation effect. The lower limit value of E2 / A2 can be 0.25.

[0192] E2 / A2 has an upper limit value. E2 / A2 cannot be greater than the upper limit value of E2 / A2. When E2 / A2 is greater than the upper limit value of E2 / A2, the shortest distance D2 from the opening 2841 of the receiving groove 284 to the edge of the second heat dissipation plate 28 can be too large, causing the space dimension occupied by the second heat dissipation plate 28 in the first direction to be too large, which will reduce the effect of the refrigerant radiator and cannot effectively dissipate heat from the power module. The upper limit value of E2 / A2 can be 0.5.

[0193] The preferred value of E2 / A2 can be 0.3, which can make the shortest distance E2 from the bottom of the receiving groove 284 to the bottom of the second heat dissipation plate 28 appropriate. When the refrigerant pipe 29 is pressed into the receiving groove 284, the dimension E2 part of the second heat dissipation plate 28 can have sufficient strength to prevent the deformation of the second heat dissipation plate 28, thereby ensuring that the dimension E2 part of the second heat dissipation plate 28 does not deform, and improving the matching effect between the refrigerant pipe 29 and the receiving groove 284 and the heat dissipation effect.

[0194] In some embodiments, the maximum depth dimension in the depth direction of the receiving groove 284 is F2. In some embodiments, F2 / A2 ≥ 0.5 and F2 / A2 ≤ 1.

[0195] F2 / A2 has a lower limit value. F2 / A2 cannot be less than the lower limit value of F2 / A2. When F2 / A2 is less than the lower limit value of F2 / A2, most of the refrigerant pipe 29 cannot be arranged in the receiving groove 284, making the refrigerant pipe 29 easily detached from the receiving groove 284, which is not convenient for fixing and restricting the refrigerant pipe 29. The lower limit value of F2 / A2 can be 0.5.

[0196] F2 / A2 has an upper limit value. F2 / A2 cannot be greater than the upper limit value of F2 / A2. When F2 / A2 is greater than the upper limit value of F2 / A2, the refrigerant pipe 29 can be completely accommodated in the receiving groove 284, making the deformation ribs need to be bent at a large angle to abut against the refrigerant pipe, which is not conducive to the deformation ribs abutting against the refrigerant pipe and fixing and restricting the refrigerant pipe. The too large angle bending of the deformation ribs will also affect the structural strength of the deformation ribs. The upper limit value of F2 / A2 can be 1.

[0197] The preferred value of F2 / A2 can be 0.8, which is convenient for the refrigerant pipe 29 to deform after being pressed in the depth direction of the receiving groove 284, and is convenient for the refrigerant pipe 29 to cooperate with the receiving groove 284 after deformation. After the refrigerant pipe 29 is deformed, the deformed ribs are bent and abutted against the refrigerant pipe to limit the refrigerant pipe 29 in the receiving groove 284, which can prevent the refrigerant pipe 29 from detaching from the connection with the receiving groove 284, and the refrigerant pipe can be restricted and fixed by bending the deformed ribs.

[0198] After the refrigerant pipe 29 is deformed, the refrigerant pipe 29 is restricted in the receiving groove 284, which can prevent the refrigerant pipe 29 from detaching from the connection with the receiving groove 284.

[0199] In some embodiments, a manufacturing tool for pressing the refrigerant pipe 29 can be provided, and a convex portion adapted to the deformation groove 287 is provided on one side of the manufacturing tool. The convex portion is inserted into the deformation groove 287, and the manufacturing tool squeezes the refrigerant pipe 29 in the direction close to the second heat dissipation plate 28 to press the refrigerant pipe 29 in the receiving groove 284.

[0200] See Figures 5 - 10 , in some embodiments, the fastener passes through the seventh connection hole 285 to be connected to the first heat dissipation plate 24, so as to facilitate the connection of the first heat dissipation plate 24 and the second heat dissipation plate 28. The first heat dissipation plate is in contact with the power module, which is convenient for the refrigerant radiator 208 to dissipate heat from the power module 26.
