Description

outdoor unit of air conditioner and air conditioner

[0001] This disclosure claims priority to Chinese patent application No. 202422136382.2, filed on August 30, 2024; and to Chinese patent application No. 202422413330.5, filed on September 30, 2024; the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of air conditioning technology, and in particular to an outdoor unit and an air conditioner. Background Technology

[0003] The outdoor unit of the air conditioner includes a casing, and a partition is provided inside the casing to divide the interior of the casing into a first chamber and a second chamber. The first chamber is equipped with a compressor, and the second chamber is equipped with an outdoor heat exchange fan and an outdoor heat exchanger. A refrigerant circuit is provided between the compressor and the outdoor heat exchanger. Outdoor air is driven into the casing by the outdoor heat exchange fan, exchanges heat with the outdoor heat exchanger, and is then blown outdoors.

[0004] The casing contains a circuit board. In some outdoor air conditioning units, refrigerant is used as the heat exchange medium to dissipate heat from the power modules on the circuit board. Refrigerant flows through the refrigerant radiator, which contacts the power modules on the circuit board to dissipate heat from the power modules.

[0005] A refrigerant radiator may include a heat sink and refrigerant pipes. In some solutions, the refrigerant pipes are passed through the receiving groove on the heat sink and then pressed together. However, the refrigerant pipes may deform or bend during production and transportation, making it difficult for them to pass through the receiving groove. This results in low pipe-passing efficiency and a high scrap rate.

[0006] Public content

[0007] This disclosure aims to improve the problem of low pipe installation efficiency and high scrap rate of refrigerant pipes in outdoor air conditioning units.

[0008] This disclosure provides an outdoor unit for an air conditioner, comprising:

[0009] The housing has an internal cavity;

[0010] A partition is disposed within the accommodating cavity, the partition dividing the accommodating cavity into a first chamber and a second chamber;

[0011] The compressor is located within the first chamber;

[0012] An outdoor heat exchanger, wherein a refrigerant circuit is provided between the outdoor heat exchanger and the compressor and the indoor heat exchanger;

[0013] An outdoor heat exchange fan is installed in the second chamber. When the outdoor heat exchange fan is in operation, it rotates to drive outdoor air into the housing, so that the outdoor air entering the housing exchanges heat with the outdoor space in the outdoor heat exchanger.

[0014] An electrical assembly box, at least a portion of which is disposed within the first cavity;

[0015] A circuit board, located inside the electrical assembly box, includes a power module;

[0016] A refrigerant radiator is used to dissipate heat from the power module; the refrigerant radiator includes:

[0017] A first heat sink plate is abutted against and connected to the power module.

[0018] The second heat sink abuts against and is connected to the first heat sink, and a receiving groove is provided on the side of the second heat sink away from the first heat sink.

[0019] The refrigerant pipe is pressed into the receiving tank by a pipe pressing process;

[0020] The outer diameter of the refrigerant pipe before it is pressed is defined as A1, and the width of the opening of the receiving groove is defined as B1, where B1 / A1≥1.005 and B1 / A1≤1.1.

[0021] By setting B1 / A1≥1.005, this disclosure ensures that the width of the opening of the receiving groove is not less than the length of the outer diameter of the refrigerant pipe before it is pressed. This allows the refrigerant heat dissipation pipe to be directly placed into the receiving groove through the opening, avoiding the problem that the refrigerant pipe cannot pass through the receiving groove along its length extension direction. This also ensures that even if the refrigerant is deformed or bent, it can still be placed into the receiving groove, improving the assembly efficiency of the refrigerant pipe and the receiving groove, and guaranteeing the fit strength between the refrigerant pipe and the receiving groove after pressing.

[0022] By setting B1 / A1≤1.1, this disclosure ensures that the width of the opening of the receiving groove is not too large relative to the length of the outer diameter of the refrigerant pipe before it is pressed, thus guaranteeing the fit strength between the refrigerant pipe and the receiving groove after the refrigerant pipe is pressed, and preventing the refrigerant pipe from coming out of the receiving groove.

[0023] This disclosure also provides an outdoor unit for an air conditioner, comprising:

[0024] The housing has an internal cavity;

[0025] A partition is disposed within the accommodating cavity, the partition dividing the accommodating cavity into a first chamber and a second chamber;

[0026] The compressor is located within the first chamber;

[0027] An outdoor heat exchanger, wherein a refrigerant circuit is provided between the outdoor heat exchanger and the compressor and the indoor heat exchanger;

[0028] An outdoor heat exchange fan is installed in the second chamber. When the outdoor heat exchange fan is in operation, it rotates to drive outdoor air into the housing, so that the outdoor air entering the housing exchanges heat with the outdoor space in the outdoor heat exchanger.

[0029] An electrical assembly box, at least a portion of which is disposed within the first cavity;

[0030] A circuit board, located inside the electrical assembly box, includes a power module;

[0031] A refrigerant radiator is used to dissipate heat from the power module; the refrigerant radiator includes:

[0032] A first heat sink plate is abutted against and connected to the power module.

[0033] The second heat sink abuts against and is connected to the first heat sink, and a receiving groove is provided on the side of the second heat sink away from the first heat sink.

[0034] The refrigerant pipe is pressed into the receiving tank by a pipe pressing process;

[0035] The shortest distance from the opening of the receiving groove to the edge of the second heat sink is defined as D1 in the width direction of the receiving groove, where D1 / A1≥0.25.

[0036] By setting D1 / A1≥0.25, this disclosure ensures that the shortest distance D1 between the opening of the receiving groove and the edge of the second heat sink is not too small. This ensures that when the refrigerant pipe is pressed into the receiving groove, the portion of the second heat sink with dimension D1 has sufficient strength to prevent deformation of the second heat sink, thereby ensuring that the portion of the second heat sink with dimension D1 does not deform, and improving the fit between the refrigerant pipe and the receiving groove and the heat dissipation effect.

[0037] This disclosure further provides an outdoor unit for an air conditioner, comprising:

[0038] The housing has an internal cavity;

[0039] A partition is disposed within the accommodating cavity, the partition dividing the accommodating cavity into a first chamber and a second chamber;

[0041] An outdoor heat exchanger, wherein a refrigerant circuit is provided between the outdoor heat exchanger and the compressor and the indoor heat exchanger;

[0042] An outdoor heat exchange fan is installed in the second chamber. When the outdoor heat exchange fan is in operation, it rotates to drive outdoor air into the housing, so that the outdoor air entering the housing exchanges heat with the outdoor space in the outdoor heat exchanger.

[0043] An electrical assembly box, at least a portion of which is disposed within the first cavity;

[0044] A circuit board, located inside the electrical assembly box, includes a power module;

[0045] A refrigerant radiator is configured to dissipate heat from the power module; the refrigerant radiator includes:

[0046] A first heat sink plate is abutted against and connected to the power module.

[0047] The second heat sink abuts against and is connected to the first heat sink, and a receiving groove is provided on the side of the second heat sink away from the first heat sink.

[0048] A refrigerant pipe is disposed in the receiving tank and is connected to the refrigerant circuit;

[0049] The second heat sink also includes:

[0050] The deformation groove is located on the side of the second heat sink away from the first heat sink;

[0051] A deformable rib is located between the receiving groove and the deformable groove;

[0052] The deformable rib bends toward the refrigerant pipe to bring the deformable rib into contact with the refrigerant pipe, and the deformable rib is configured to limit the swaying of the refrigerant pipe.

[0053] This disclosure, by setting a deformation rib, can limit the refrigerant pipe set in the receiving groove, preventing or improving the risk of the refrigerant pipe falling out of the receiving groove. The refrigerant pipe is set in the receiving groove, and the deformation rib is bent towards the refrigerant pipe so that the deformation rib contacts the refrigerant pipe, making the installation of the refrigerant pipe and the second heat sink convenient, improving the installation efficiency between the refrigerant pipe and the second heat sink plate, and preventing or improving the damage to the refrigerant pipe caused by pressing.

[0054] This disclosure further provides an outdoor unit for an air conditioner, comprising:

[0064] The second heat sink abuts against and is connected to the first heat sink, and a receiving groove is provided on the side of the second heat sink away from the first heat sink.

[0065] A refrigerant pipe is disposed in the receiving tank and is connected to the refrigerant circuit;

[0066] The second heat sink also includes:

[0093] The following description, in conjunction with the accompanying drawings, clearly and completely describes some embodiments of this disclosure. Obviously, the described embodiments are merely some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments provided in this disclosure are within the scope of protection of this disclosure.

[0094] Referring to Figures 1 and 2, some embodiments of this disclosure provide an air conditioner 1000, which may include an indoor unit 100 and an outdoor unit 200. The indoor unit 100 is installed in an indoor space. The outdoor unit 200 is installed in an outdoor space and configured for heat exchange with the outdoor environment. The indoor unit 100 and the outdoor unit 200 are connected by a pipe 400.

[0095] The indoor unit of the air conditioner can be a ducted air conditioner, a wall-mounted air conditioner, or a floor-standing air conditioner, etc. This disclosure mainly uses a wall-mounted air conditioner as an example.

[0096] In some embodiments of this disclosure, referring to FIG3, the indoor unit 100 of the air conditioner may include a main body 300, which has a bottom and a top. The height direction of the main body 300 is from the bottom to the top of the main body 300.

By operating the heat exchange fan, indoor air is introduced into the first cavity through the heat exchange inlet, then flows through the indoor heat exchanger 1001, through the heat exchange duct, and finally through the heat exchange outlet 32 ​​before flowing into the room. The heat exchange fan is positioned on the leeward side of the indoor heat exchanger 1001 to reduce the resistance of the indoor heat exchanger 1001 to airflow and increase the airflow into the room. The outdoor unit 200 of the air conditioner may be disposed in the outdoor space. Referring to Figure 4, the outdoor unit 200 may include a housing, which constitutes the external structure of the outdoor unit.

[0102] In some embodiments of this disclosure, as shown in FIG5, the outdoor unit of the air conditioner may include a partition 22, which may be disposed inside the housing 21. The partition 22 divides the interior of the housing 21 into a first chamber 211 and a second chamber 212, which are respectively configured to accommodate corresponding components.

[0103] In some embodiments of this disclosure, the first chamber 211 and the second chamber 212 are arranged side by side. The first chamber 211 and the second chamber 212 can communicate with each other.

[0104] In some embodiments of this disclosure, 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 disposed opposite to each other. The outdoor air outlet is disposed on the front side of the housing 21, and the outdoor air inlet is disposed on the rear side of the housing 21. The outdoor air inlet communicates with the outdoor space and the second chamber 212, and the outdoor air outlet communicates 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 to the top of the housing 21.

[0105] In some embodiments of this disclosure, as shown in Figures 2 and 5, the outdoor unit 200 of the air conditioner may include a compressor 201, which is disposed in the first chamber 211 and installed at the bottom of the outdoor unit 200.

[0106] In some embodiments of this disclosure, as shown in Figures 2 and 5, the outdoor unit 200 of the air conditioner may include an outdoor heat exchanger 202. A refrigerant circuit is provided between the compressor 201, the outdoor heat exchanger 202, and the indoor heat exchanger 1001. Refrigerant flows through the indoor heat exchanger 1001, the outdoor heat exchanger 202, and the refrigerant circuit. The refrigerant circuit is sequentially connected to the compressor 201, the outdoor heat exchanger 202, and the indoor heat exchanger 1001. The refrigerant can flow through the compressor 201, the outdoor heat exchanger 202, and the indoor heat exchanger 1001 and then flow back into the compressor 201. The refrigerant in the outdoor heat exchanger 202 may be configured to exchange heat with the air flowing through the outdoor heat exchanger 202 into the second chamber.

[0107] In some embodiments of this disclosure, the outdoor unit 200 of the air conditioner may include an outdoor heat exchange fan, which may be disposed in the second chamber 212. When the outdoor heat exchange fan is in operation, it rotates to drive outdoor air into the housing 21, so that the outdoor air entering the housing 21 exchanges heat with the outdoor space in the outdoor heat exchanger.

[0108] In some embodiments of this disclosure, as shown in Figures 2 and 5, the outdoor unit 200 of the air conditioner may include a throttling device 204 disposed in a first chamber and configured to expand a high-temperature, high-pressure liquid refrigerant into a low-pressure liquid refrigerant.

[0109] In some embodiments of this disclosure, the throttling device 204 may be located on the leeward side of the outdoor heat exchanger 202, which facilitates connection to the compressor 201.

[0110] In this disclosure, the air conditioner 1000 performs a refrigeration cycle by using a compressor 201, an outdoor heat exchanger 202, a throttling device 204, and an indoor heat exchanger 1001. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplying refrigerant to the conditioned and heat-exchanged air.

[0111] In this system, compressor 201 compresses the refrigerant gas at low temperature and low pressure, discharging it at high temperature and high pressure. The discharged refrigerant gas flows into outdoor heat exchanger 202. Outdoor heat exchanger 202 condenses the compressed refrigerant into a liquid phase, releasing heat to the surrounding environment through the condensation process. Throttling device 204 expands the high-temperature, high-pressure liquid refrigerant condensed in outdoor heat exchanger 202 into a low-pressure liquid refrigerant. Indoor heat exchanger 1001 evaporates the refrigerant that has expanded in throttling device 204, returning the low-temperature, low-pressure refrigerant gas to compressor 201. Indoor heat exchanger 1001 achieves a cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, air conditioner 1000 regulates the temperature of the indoor space.

[0112] Of the indoor heat exchanger 1001 and the outdoor heat exchanger 202, one 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 is used as a heater in 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 is used as a cooler in cooling mode.

[0113] In some embodiments of this disclosure, the outdoor unit 200 of the air conditioner may include an electrical control assembly, at least a portion of which is disposed within the first chamber 211. The electrical control assembly may be configured to control the operation of the outdoor unit 200 of the air conditioner.

[0115] In some embodiments of this disclosure, the electrical box assembly may include a circuit board connected inside the electrical box 23.

[0116] In some embodiments of this disclosure, referring to FIG7, the circuit board may include a circuit board body 25 disposed within an electrical enclosure 23, and the circuit board body 25 may be a printed circuit board. The circuit board may also include electronic components mounted on the circuit board body 25.

[0117] In some embodiments of this disclosure, the plane containing the circuit board body 25 is horizontally arranged. The circuit board can be disposed within a small-sized housing 21, and the circuit board can span across the first chamber 211 and the second chamber 212, that is, at least a portion of the circuit board is disposed within the first chamber 211 and at least a portion of the circuit board is disposed within the second chamber 212, so as to reduce the space occupied within the first chamber 211.

[0118] It should be noted that the term "parallel" as used in this disclosure includes absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism can be, for example, within 5°. In some embodiments of this disclosure, the plane containing the circuit board body 25 is vertically arranged, allowing the circuit board to be placed within a large housing 21. Due to the large size of the housing 21, the entire circuit board can be placed within the first chamber 211 without significantly impacting the space occupied by the first chamber 211. The circuit board body 25 can be configured according to the size and spatial structure of the outdoor unit of the air conditioner.

[0119] It should be noted that the term "vertical" as used in this disclosure includes absolute verticality and approximate verticality, wherein the acceptable deviation range for approximate verticality can be, for example, within 5°.

[0120] In some embodiments of this disclosure, the circuit board is fixedly connected inside the electrical assembly box 23. The circuit board and the electrical assembly box 23 can be connected by snap-fit ​​or by fasteners. This ensures a stable connection between the circuit board and the electrical assembly box 23 and also facilitates disassembly and assembly.

[0121] In some embodiments of this disclosure, referring to FIG7, the circuit board may include a power module 26, which is disposed on the circuit board body 25 and connected to the circuit board body 25 by soldering to ensure that the power module 26 is stably fixed on the circuit board body 25, thereby ensuring the stability of the electrical connection.

The IGBT power module 26 generates heat during operation, making it one of the main heat sources on the circuit board body 25. To ensure the normal operation and reliability of the circuit board body 25, heat dissipation measures are required for the power module 26.

[0123] It should be noted that the power module 26 is not limited to IGBTs, but can also be a power structure such as a silicon bridge diode.

[0124] In some embodiments of this disclosure, the power module 26 has a chip, which is encapsulated in a plastic package. The power module 26 has pins, with each end of the pin connected to the chip and the circuit board body 25, respectively. The power module 26 may have connection holes, through which fasteners can pass to fix the power module 26 to the first heat sink 24. In some embodiments of this disclosure, referring to FIG7, the outdoor unit 200 of the air conditioner may include a module bracket 51, which is disposed between the power module 26 and the circuit board. The module bracket 51 is configured to support the power module 26, which can improve the situation where the solder joints of the power module 26 connected to the circuit board are damaged due to stress, thereby reducing the damage rate of the power module 26.

[0125] In some embodiments of this disclosure, referring to FIG5, the outdoor unit 200 of the air conditioner may include a refrigerant radiator 208 disposed within a first chamber 211. The refrigerant radiator 208 may be connected to an electrical assembly. The refrigerant radiator 208 is configured to dissipate heat from the power module 26.

In other words, the second heat sink 28 may include the receiving groove 284, which is disposed on the side of the second heat sink 28 away from the first heat sink 24, and the receiving groove 284 is recessed into the interior of the second heat sink 28.

[0129] In some embodiments of this disclosure, a first heat sink 24 abuts against and is connected to the power module 26. The side of the first heat sink 24 away from the power module 26 contacts a second heat sink 28, which abuts against and is connected to the first heat sink 24. Heat generated by the power module 26 is transferred through the first heat sink 24 to the second heat sink 28, and then dissipated through heat transfer with the refrigerant pipe 29, thus cooling the power module 26.

[0130] In some embodiments of this disclosure, the power module 26 has pins on both sides in its width direction, and the first heat sink 24 has a boss on the side away from the second heat sink 28, on which the power module 26 can be mounted. The surface of the power module 26 in contact with the boss is the first surface, and the surface of the boss in contact with the power module 26 is the second surface. The dimension of the first surface in the width direction of the power module 26 is larger than the dimension of the second surface in the width direction of the power module 26, and the two edges of the first surface in the width direction of the power module 26 protrude correspondingly relative to the two edges of the second surface in the width direction of the power module 26, so as to ensure a safe electrical clearance between the pins of the first heat sink 24 and the power module 26.

[0131] In some embodiments of this disclosure, while ensuring a safe electrical clearance between the pins of the first heat sink 24 and the power module 26, the distance between the two edges of the first surface in the width direction of the power module 26 and the corresponding protrusions of the two edges of the second surface in the width direction of the power module 26 can be less than 2 mm.

[0132] In some embodiments of this disclosure, the first heat sink 24 may be omitted, allowing the power module 26 to be directly mounted on the second heat sink 28, thereby reducing costs.

[0133] In some embodiments of this disclosure, as shown in Figures 8 to 10, the refrigerant radiator 208 may include a refrigerant pipe 29, which is disposed in a receiving groove 284 and is connected to a refrigerant circuit.

[0134] In some embodiments of this disclosure, at least two receiving slots 284 may be provided, with the two receiving slots 284 arranged side by side, and a refrigerant pipe 29 passing through the two receiving slots 284 in sequence to connect with the receiving slots 284.

[0135] In some embodiments of this disclosure, the refrigerant pipe 29 is placed in the receiving groove 284, and the refrigerant pipe 29 is deformed and squeezed to both sides of the receiving groove 284 by external force, so that the refrigerant pipe 29 is in close contact with the inner circumferential surface of the receiving groove 284, and the refrigerant pipe 29 is adapted to the receiving groove 284.

[0136] In some embodiments of this disclosure, the receiving groove 284 has an opening 2841 on the second heat sink 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. Referring to FIG8, the width of the opening 2841 of the receiving groove 284 is defined as B1.

[0137] In some embodiments of this disclosure, as shown in Figures 8 to 10, the outer diameter of the refrigerant pipe 29 before pressing is defined as A1, and B1 / A1 ≥ the third parameter value, which can be any value between 1.005 and 1.1. When the third parameter value is 1.005, i.e., B1 / A1 ≥ 1.005, the width of the opening 2841 of the receiving groove 284 is not less than the length of the outer diameter of the refrigerant pipe 29 before pressing. This allows the refrigerant pipe 29 to be directly placed into the receiving groove 284 through the opening 2841, avoiding the problem that the refrigerant pipe 29 cannot pass through the receiving groove 284 along its length extension direction. This ensures that even if the refrigerant pipe 29 is deformed or 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 also ensuring the fit strength between the refrigerant pipe 29 and the receiving groove 284 after pressing.

[0138] In some embodiments of this disclosure, B1 / A1 ≤ the fourth parameter value, which can be any value between 1.005 and 1.1. When the fourth parameter value is 1.1, i.e. B1 / A1 ≤ 1.1, the width of the opening 2841 of the receiving groove 284 is not too large relative to the length of the outer diameter of the refrigerant pipe 29 before it is pressed, so that after the refrigerant pipe 29 is pressed, the fit strength between the refrigerant pipe 29 and the receiving groove 284 can be guaranteed, so that the refrigerant pipe 29 will not come out of the receiving groove 284.

[0139] In some embodiments of this disclosure, the direction in which the receiving groove 284 extends is defined as the length direction of the receiving groove 284, the width of the opening 2841 of the receiving groove 284 is in the same direction as the width direction of the receiving groove 284, and the length direction of the receiving groove 284 is perpendicular to the width direction of the receiving groove 284.

[0140] In some embodiments of this disclosure, referring to Figures 8 and 10, the distance between the two furthest points of the receiving groove 284 in the width direction is defined as the third distance C1, the outer diameter of the refrigerant pipe 29 before being pressed is A1, and C1 / A1 ≥ the fifth parameter value, which can be any value between 1.1 and 1.4. When the fifth parameter value is 1.1, i.e., C1 / A1 ≥ 1.1, the width of the refrigerant pipe 29 after being pressed is not too small, allowing the refrigerant pipe 29 to undergo a certain deformation after being pressed, ensuring that the deformation of the refrigerant pipe 29 relative to the receiving groove 284 after being pressed is not too small, thereby improving the fit strength between the refrigerant pipe 29 and the receiving groove 284.

[0141] In some embodiments of this disclosure, C1 / A1 ≤ the sixth parameter value, which can be any value between 1.1 and 1.4. When the sixth parameter value is 1.4, i.e., C1 / A1 ≤ 1.4, the width inside the receiving groove 284 is not too large, so that the refrigerant pipe 29 can contact and cooperate with the inside of the receiving groove 284 after being pressed, thereby improving the fit strength between the refrigerant pipe 29 and the receiving groove 284, improving or preventing the refrigerant pipe 29 from shaking randomly inside the receiving groove 284, and reducing or avoiding the risk of the refrigerant pipe 29 falling out of the receiving groove 284.

[0142] In some embodiments of this disclosure, referring to Figures 8 and 10, the shortest distance from the opening 2841 of the receiving groove 284 to the edge of the second heat sink 28 is defined as D1 in the width direction of the receiving groove 284, where D1 / A1 ≥ the value of the seventh parameter. The value of the seventh parameter can be any value between 0.25 and 2. When the value of the seventh parameter is 0.25, i.e., D1 / A1 ≥ 0.25, the shortest distance D1 from the opening 2841 of the receiving groove 284 to the edge of the second heat sink 28 is not too small. This ensures that when the refrigerant pipe 29 is pressed into the receiving groove 284, the portion of the second heat sink 28 with size D1 has sufficient strength to prevent deformation of the second heat sink 28, thereby ensuring that the portion of the second heat sink 28 with size D1 does not deform, and improving the fit and heat dissipation effect between the refrigerant pipe 29 and the receiving groove 284.

[0143] In some embodiments of this disclosure, referring to Figures 8 and 10, the depth direction of the receiving groove 284 is defined as the first direction. In the first direction, the shortest distance from the bottom of the receiving groove 284 to the bottom of the second heat sink 28 is E1, where E1 / A1 ≥ the value of the eighth parameter. The value of the eighth parameter can be any value between 0.25 and 2. When the value of the eighth parameter is 0.25, i.e., E1 / A1 ≥ 0.25, the shortest distance E1 from the bottom of the receiving groove 284 to the bottom of the second heat sink 28 is not too small. This ensures that when the refrigerant pipe 29 is pressed into the receiving groove 284, the portion of the second heat sink 28 with size E1 has sufficient strength to prevent deformation of the second heat sink 28, thereby ensuring that the portion of the second heat sink 28 with size E1 does not deform, and thus improving the fit and heat dissipation effect between the refrigerant pipe 29 and the receiving groove 284.

[0144] In some embodiments of this disclosure, referring to Figures 8 and 10, the depth direction of the receiving groove 284 is defined as the first direction. In the first direction, the shortest distance from the bottom of the receiving groove 284 to the top of the second heat sink 28 is F1, where F1 / A1 ≥ the eighth parameter value. The eighth parameter value can be any value between 0.5 and 1. The eighth parameter value can be 0.5, that is, F1 / A1 ≥ 0.5. This ensures that the refrigerant pipe 29 is not excessively deformed in the depth direction of the receiving groove 284, thus guaranteeing the flow area of ​​the refrigerant in the refrigerant pipe 29 and improving the heat dissipation effect of the refrigerant.

[0145] In some embodiments of this disclosure, F1 / A1 ≤ the ninth parameter value, which can be any value between 0.5 and 1. The ninth parameter value can be 1, i.e., F1 / A1 ≤ 1. This allows the refrigerant pipe 29 to deform after being pressed into the depth direction of the receiving groove 284, facilitating the fitting of the refrigerant pipe 29 with the receiving groove 284 after deformation. After deformation, the refrigerant pipe 29 is confined within the receiving groove 284, preventing or reducing the risk of the refrigerant pipe 29 detaching from the connection with the receiving groove 284.

[0146] In some embodiments of this disclosure, referring to FIG11, the depth direction of the receiving groove 284 is defined as the first direction. After the refrigerant pipe 29 is pressed into the receiving groove 284, the farthest 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 in the first direction is G1, where G1 < A1. This allows the refrigerant pipe 29 to deform after being pressed into the receiving groove 284, facilitating the fitting of the refrigerant pipe 29 with the receiving groove 284 after deformation. After deformation, the refrigerant pipe 29 is confined within the receiving groove 284, preventing or reducing the risk of the refrigerant pipe 29 detaching from the connection with the receiving groove 284.

[0147] It should be noted that after the refrigerant pipe 29 is deformed by pressure, the side of the refrigerant pipe 29 away from the bottom of the receiving tank 284 is not limited to the plane shown in Figure 11, but can also be an arc-shaped surface, etc., depending on the specific situation.

[0148] In some embodiments of this disclosure, G1≥F1, which makes the pipe diameter height of the refrigerant pipe 29 after being pressed at least equal to the depth of the receiving groove 284, or the pipe diameter height of the refrigerant pipe 29 after being pressed at greater than the depth of the receiving groove 284. This makes the fit between the refrigerant pipe 29 and the receiving groove 284 easier to process, and also satisfies the fit strength between the refrigerant pipe 29 and the receiving groove 284, preventing or reducing the refrigerant pipe 29 from detaching from the receiving groove 284.

[0149] In some embodiments of this disclosure, referring to Figures 8 and 10, the second heat sink 28 includes at least two receiving slots 284. The distance between the centers of two adjacent receiving slots 284 is H1, where H1 / A1 ≥ the tenth parameter value. The tenth parameter value can be any value between 4 and 6. The tenth parameter value can be 4, i.e., H1 / A1 ≥ 4, which ensures that the distance between two adjacent receiving slots 284 is not too small, and that the bent refrigerant pipe 29 can be easily placed into the two adjacent receiving slots 284.

[0150] In some embodiments of this disclosure, H1 / A1 ≤ the eleventh parameter value, which can be any value between 4 and 6. The eleventh parameter value can be 6, i.e., H1 / A1 ≤ 6. This ensures that the distance between two adjacent receiving slots 284 is not too large, that the space occupied by the second heat sink 28 is not too large, and that the distance between adjacent refrigerant pipes 29 is not too large, thereby improving the heat dissipation effect of the refrigerant radiator 208.

[0151] In some embodiments of this disclosure, referring to FIG9, the refrigerant pipe 29 may include straight pipe sections 291 disposed in the receiving groove 284, the number of straight pipe sections 291 corresponding to the number of sections in the receiving groove 284, and the extension direction of the straight pipe sections 291 being arranged in the same direction as the extension direction of the receiving groove 284.

[0152] In some embodiments of this disclosure, the refrigerant pipe 29 may include a bend 292 that connects two adjacent straight pipe sections 291.

[0153] In some embodiments of this disclosure, the straight pipe section 291 and the bent pipe section 292 are integrally formed. The bent pipe section 292 and the straight pipe section 291 are formed by bending the refrigerant pipe 29, which reduces costs while ensuring the structural strength of the refrigerant pipe 29. The bent pipe section 292 may be disposed outside the receiving groove 284.

[0154] In some embodiments of this disclosure, the outer diameter A1 of the straight pipe section 291 before compression may be the same as the outer diameter of the bent pipe section 292.

[0155] In some embodiments of this disclosure, referring to FIG9, the distance between the centers of two adjacent straight pipe sections 291 is Z1, wherein Z1 / A1 ≥ the twelfth parameter value, the twelfth parameter value can be any value between 4 and 6, and the twelfth parameter value can be 4, that is, Z1 / A1 ≥ 4, which ensures that the distance between two adjacent straight pipe sections 291 is not too small, and that the bent refrigerant pipe 29 can be easily placed into two adjacent receiving tanks 284.

[0156] In some embodiments of this disclosure, Z1 / A1 ≤ the thirteenth parameter value, which can be any value between 4 and 6. The thirteenth parameter value can be 6, i.e., Z1 / A1 ≤ 6. This ensures that the distance between two adjacent straight pipe sections 291 is not too large, and that the distance between the receiving grooves 284 that cooperate with the straight pipe section 291 is not too large. This also ensures that the space occupied by the second heat sink 28 is not too large, thus avoiding the situation where the heat dissipation effect of the refrigerant heat sink 208 deteriorates due to the excessive distance between two adjacent straight pipe sections 291.

[0157] In some embodiments of this disclosure, the length of the outer diameter of the refrigerant pipe 29 before it is pressed is A1, where A1 ≥ the fourteenth parameter value. The fourteenth parameter value can be any value between 4.76, 6, 6.35, 7, 7.94, 8, 9.52, 9.53, 12, or 12.7. The above values ​​are national standard metric and imperial dimensions. When the fourteenth parameter value is 4.76, that is, A1 ≥ 4.76, the pipe diameter of the refrigerant pipe 29 meets the national standard metric and imperial dimensions, which can ensure that the size of the refrigerant pipe 29 is not too small and facilitates the universal assembly of the refrigerant pipe 29.

[0158] In some embodiments of this disclosure, A1 ≤ the fifteenth parameter value, which can be any value between 4.76, 6, 6.35, 7, 7.94, 8, 9.52, 9.53, 12, or 12.7. The above values ​​are national standard metric and imperial dimensions. When the fifteenth parameter value is 12.7, that is, A1 ≤ 12.7, the diameter of the refrigerant pipe 29 meets the national standard metric and imperial dimensions, which can ensure that the size of the refrigerant pipe 29 is not too large and facilitates the universal assembly of the refrigerant pipe 29.

[0159] In some embodiments of this disclosure, as shown in FIG6, the second heat sink 28 may include a seventh connection hole 285, which penetrates the second heat sink 28. Fasteners pass through the seventh connection hole 285 to connect to the electrical assembly, so as to facilitate the refrigerant radiator 208 to dissipate heat from the electrical assembly.

[0160] In some embodiments, the fastener passes through the seventh connecting hole 285 to connect to the first heat sink 24, so as to connect the first heat sink 24 and the second heat sink 28, so as to facilitate the refrigerant radiator 208 to dissipate heat from the power module 26.

[0161] In some embodiments of this disclosure, referring to FIG12, the second heat sink 28 may include a deformation groove 287, which is located on the side of the second heat sink 28 away from the first heat sink 24. The deformation groove 287 corresponds to the deformation rib 286, and the deformation groove 287 corresponding to the deformation rib 286 is disposed on the side of the deformation rib 286 away from the receiving groove 284. The deformation groove 287 is recessed into the interior of the second heat sink 28 to facilitate the application of external force to the deformation rib 286 within the deformation groove 287, thereby facilitating the bending of the deformation rib 286 and thus facilitating the confinement of the refrigerant pipe 29 within the receiving groove 284.

[0162] In some embodiments of this disclosure, the deformation groove 287 may be configured as a V-shaped groove, a square groove, or other irregularly shaped groove, without specific limitation herein.

[0163] In some embodiments of this disclosure, as shown in FIG12, deformable ribs 286 are respectively provided on both sides of the receiving groove 284 in the second direction, and deformable grooves 287 corresponding to the deformable ribs 286 are provided on the side of the deformable ribs 286 away from the receiving groove 284. The number of deformable grooves 287 corresponds one-to-one with the number of deformable ribs 286.

[0164] In some embodiments of this disclosure, referring to FIG12, the second heat sink 28 may include a deformable rib 286 located between the receiving groove 284 and the deformable groove 287. The deformable rib 286 may be disposed at the edge of the opening. The deformable rib 286 is bent toward the refrigerant pipe 29 so that it contacts the refrigerant pipe 29. At this time, the deformable rib 286 deforms and is configured to limit the swaying of the refrigerant pipe 29. The contact between the deformable rib 286 and the refrigerant pipe 29 can prevent the refrigerant pipe 29 from dislodging from the receiving groove 284.

[0165] This disclosure utilizes the deformation rib 286 to limit the refrigerant pipe 29 disposed within the receiving groove 284, thereby reducing or preventing the refrigerant pipe 29 from detaching from the receiving groove 284. By placing the refrigerant pipe 29 within the receiving groove 284 and bending the deformation rib 286 towards the refrigerant pipe 29 to bring the deformation rib 286 into contact with the refrigerant pipe 29, the installation of the refrigerant pipe 29 and the second heat sink 28 becomes convenient, improving the installation efficiency between the refrigerant pipe 29 and the second heat sink 28, and preventing damage to the refrigerant pipe 29 caused by pressing it down.

[0166] In some embodiments of this disclosure, when assembling the refrigerant pipe 29 and the second heat sink 28, the refrigerant pipe 29 is placed into the receiving groove 284, and a pressing process is used to deform the refrigerant pipe 29, squeezing it towards both sides of the receiving groove 284, so that the refrigerant pipe 29 is tightly attached to the inner circumferential surface of the receiving groove 284, thus adapting the refrigerant pipe 29 to the receiving groove 284. The deforming rib 286 is bent towards the refrigerant pipe 29 so that the deforming rib 286 contacts the refrigerant pipe 29. At this time, the deforming rib 286 deforms, and the contact between the deforming rib 286 and the refrigerant pipe 29 prevents the refrigerant pipe 29 from detaching from the receiving groove 284.

[0167] In this disclosure, the refrigerant pipe 29 is pressed into place by external force in a first direction, ensuring that the refrigerant pipe 29 is tightly attached to the inner circumferential surface of the receiving groove 284 after pressing. This guarantees the fit strength between the refrigerant pipe 29 and the receiving groove 284. The deformable rib 286 is bent towards the refrigerant pipe 29 to bring it into contact with the refrigerant pipe 29. This contact prevents the refrigerant pipe 29 from detaching from the receiving groove 284. This simple operation improves the installation efficiency of the refrigerant pipe 29 and the second heat sink 28.

[0168] In some embodiments of this disclosure, referring to FIG13, the outer diameter of the straight pipe section 291 before compression is the same as the outer diameter A2 of the bent pipe section 292.

[0169] In some embodiments, the second heat sink 28 may include at least two receiving slots 284, which are arranged side by side, wherein a section of refrigerant pipe 29 passes through the two receiving slots 284 in sequence to connect with the receiving slots 284.

[0170] In some embodiments of this disclosure, referring to Figures 14 and 15, the outer diameter of the bend section 292 is A2, and the dimension of the deformable rib 286 in the width direction is G2, where G2 / A2≥0.1 and G2 / A2≤0.5.

[0171] In some embodiments of this disclosure, G2 / A2 has a lower limit value. 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 deformable rib 286 will be too small relative to the outer diameter of the refrigerant pipe 29, resulting in a smaller structural strength of the deformable rib 286 after it abuts against the refrigerant pipe 29. This may cause the deformable rib 286 to deform and fail to confine the refrigerant pipe 29 within the receiving groove 284. The lower limit value of G2 / A2 can be 0.1.

[0172] In some embodiments of this disclosure, G2 / A2 has an upper limit value. 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 deformable rib 286 will be too large relative to the outer diameter of the refrigerant pipe 29, which will increase the size of the deformable rib 286 in the second direction. This may cause the deformable rib 286 to be too large and difficult to bend, which will make it difficult to fix the refrigerant pipe 29. It may also cause the size of the deformable rib 286 to be too large, which may lead to the second heat sink 28 being too large in the second direction. The upper limit value of G2 / A2 can be 0.5.

[0173] In some embodiments of this disclosure, G2 / A2 can be 0.3, which makes the width of the deformable rib 286 appropriate relative to the outer diameter of the refrigerant pipe 29. This ensures the strength of the deformable rib 286 after it abuts against the refrigerant pipe 29, avoiding the problem that the deformable rib 286 is not strong enough to confine the refrigerant pipe 29 within the receiving groove 284. It also avoids the problem that the deformable rib 286 is too large to be easily bent, and prevents the second heat sink 28 from being too large in the second direction.

[0174] In some embodiments, referring to FIG18, the width direction of the deformation groove 287 can be arranged in the same direction as the second direction, and the maximum dimension of the deformation groove 287 in the width direction is H2, H2 / A2≥0.1, H2 / A2≤0.5.

[0175] In some embodiments of this disclosure, H2 / A2 has a lower limit value. 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 the 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.

[0176] In some embodiments of this disclosure, H2 / A2 has an upper limit value. 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, which makes the cost of the second heat sink 28 higher and causes waste. The upper limit value of H2 / A2 can be 0.5.

[0177] In some embodiments of this disclosure, H2 / A2 can be 0.3, which ensures that the width of the deformation groove 287 in the second direction is not too small, so that external force can be applied to the deformation rib 286 for bending, thereby improving the bending efficiency of the deformation rib 286 and the assembly efficiency of the refrigerant pipe 29 and the second heat sink 28. It also ensures that the width of the deformation groove 287 in the second direction is not too large, which can reduce the space occupied by the deformation groove 287 in the second direction of the second heat sink 28, which is beneficial to reduce the size of the second heat sink 28, save the cost of the second heat sink 28, and make the second heat sink 28 smaller to reduce space occupation.

[0178] In some embodiments of this disclosure, referring to FIG18, the maximum dimension of the deformation groove 287 in the depth direction is I2, I2 / A2≥0.1, I2 / A2≤0.5.

[0179] In some embodiments of this disclosure, I2 / A2 has a lower limit value, and I2 / A2 cannot be less than the lower limit value of I2 / A2. When I2 / A2 is less than the lower limit value of I2 / A2, the depth of the deformation groove 287 will be too small. Since the deformation rib 286 is arranged adjacent to the deformation groove 287, the deformation rib 286 forms the side wall surface of the deformation groove 287. If the depth of the deformation groove 287 is too small, the deformation rib 286 will not be able to limit the refrigerant pipe 29 after bending in the first direction, making it easy for the refrigerant pipe 29 to fall out of the receiving groove 284. The lower limit value of I2 / A2 can be 0.1.

[0180] In some embodiments of this disclosure, I2 / A2 has an upper limit value. I2 / A2 cannot be greater than the upper limit value of I2 / A2. When I2 / A2 is greater than the upper limit value of I2 / A2, the depth dimension of the deformable rib 286 will be too long. The excessive depth dimension of the deformable rib 286 will affect the structural strength of the wall of the receiving groove 284. This may cause the structural strength of the second heat sink 28 to be insufficient to support the refrigerant pipe 29 after it is pressed into the receiving groove 284. This will cause the second heat sink 28 to be deformed by the pressure of the refrigerant pipe 29. The upper limit value of I2 / A2 can be 0.5.

[0181] In some embodiments, I2 / A2 can be 0.3. On the one hand, this ensures that the depth of the deformation groove 287 is not too small. Since the deformation rib 286 is arranged adjacent to the deformation groove 287, and the deformation rib 286 forms the side wall of the deformation groove 287, i.e., I2 / A2≥0.1, the deformation rib 286 has sufficient dimensions in the first direction for bending, so that the bent deformation rib 286 can limit the refrigerant pipe 29 and prevent the refrigerant pipe 29 from falling out of the receiving groove 284. On the other hand, this also ensures that the depth of the deformation rib 286 is not too long, so as to avoid the deformation rib 286 affecting the structural strength of the wall of the receiving groove 284 due to excessive depth. This ensures that after the refrigerant pipe 29 is pressed into the receiving groove 284, the structural strength of the second heat sink 28 can support the refrigerant pipe 29, preventing the second heat sink 28 from being deformed by the pressure of the refrigerant pipe 29.

[0182] In some embodiments, as shown in FIG16, the deformation groove 287 may include a first pressing surface 2871, the first pressing surface 2871 forming the side wall surface of the deformation groove 287, and the first pressing surface 2871 forming the side wall surface of the deformation rib 286 away from the receiving groove 284, that is, the deformation rib 286 is adjacent to the deformation groove 287, and the first pressing surface 2871 forming the side wall surface of the deformation rib 286 away from the receiving groove 284.

[0183] In some embodiments of this disclosure, as shown in FIG16, the deformation groove 287 may include a second pressing surface 2872, which forms the other side wall of the deformation groove 287. The second pressing surface 2872 is disposed opposite to the first pressing surface 2871 and is disposed away from the receiving groove 284 relative to the first pressing surface 2871.

[0184] In some embodiments of this disclosure, as shown with reference to FIG17, the bottom of 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 is away from the refrigerant radiator, the first included angle J2≥15°, and the first included angle J2≤60°.

[0185] In some embodiments of this disclosure, J2 has a lower limit value, which cannot be less than the lower limit value. When J2 is less than the lower limit value, the included angle between the first pressing surface 2871 and the second pressing surface 2872 may be too small, making it difficult for the tooling to be placed into the deformation groove 287 to press and bend the deformation rib 286, which is not conducive to limiting and installing the refrigerant pipe 29. The lower limit value of J2 can be 15°.

[0186] In some embodiments of this disclosure, J2 has an upper limit value, which cannot exceed. When J2 exceeds the upper limit value, the first included angle between the first pressing surface 2871 and the second pressing surface 2872 may become too large. An excessively large first included angle will affect the structural strength of the wall of the receiving groove 284, causing the structural strength of the second heat sink 28 to be insufficient to support the refrigerant pipe 29 after it is pressed into the receiving groove 284. The second heat sink 28 will then deform due to the pressure from the refrigerant pipe 29. The upper limit value of J2 can be 60°.

[0187] In some embodiments of this disclosure, J2 can be 50°. On the one hand, this ensures that there is a certain appropriate angle between the first pressing surface 2871 and the second pressing surface 2872, which facilitates the compression of the deformation rib 286 within the deformation groove 287 by external force, thereby facilitating 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 prevents the refrigerant pipe 29 from detaching from the receiving groove 284. On the other hand, this ensures that the first angle between the first pressing surface 2871 and the second pressing surface 2872 is not too large, thus avoiding affecting the structural strength of the wall of the receiving groove 284 due to an excessively large first angle. This ensures that after the refrigerant pipe 29 is pressed into the receiving groove 284, the structural strength of the second heat sink 28 can support the refrigerant pipe 29, preventing the second heat sink 28 from being deformed by the compression of the refrigerant pipe 29.

[0188] In some embodiments of this disclosure, referring to FIG12, the deformation groove 287 may include a third pressing surface 2873, which is disposed at the bottom of the deformation groove 287 in the depth direction. The third pressing surface 2873 is 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 2841 of the deformation groove 287 is disposed facing away from the refrigerant radiator 208. The connection between the first pressing surface 2871, the second pressing surface 2872, and the third pressing surface 2873 can form a square groove, which facilitates the compression of the first pressing surface 2871 within the deformation groove 287. That is, compression of the first pressing surface 2871 causes the deformation rib 286 to bend toward the refrigerant pipe 29, thereby restricting the refrigerant pipe 29 from swaying within the receiving groove 284 and preventing the refrigerant pipe 29 from detaching from the receiving groove 284.

[0189] In some embodiments of this disclosure, referring to Figures 18 and 19, after the deformable rib 286 is bent toward the refrigerant pipe 29 so that the deformable rib 286 comes into contact with the refrigerant pipe 29, the angle between the plane where the first pressing surface 2871 is located and the first direction is a second angle K2 ≥ 30° and K2 ≤ 60°.

[0190] In some embodiments of this disclosure, K2 has a lower limit value, which cannot be less than the lower limit value. When K2 is less than the lower limit value, the bending angle of the deformable rib 286 will be smaller, making it impossible to effectively confine the refrigerant pipe 29 within the receiving groove 284. The lower limit value of K2 can be 30°.

[0191] In some embodiments of this disclosure, K2 has an upper limit value, which cannot exceed the upper limit value. When K2 exceeds the upper limit value, the bending angle of the deformable rib 286 towards the refrigerant pipe 29 may be too large, which may cause the connection between the deformable rib 286 and the second heat sink 28 to break due to bending. The upper limit value of K2 can be 60°.

[0192] In some embodiments of this disclosure, K2 can be 45°. On the one hand, this ensures that the deformable rib 286 bends at a certain angle towards the refrigerant pipe 29, effectively restricting the refrigerant within the receiving groove 284 and preventing the refrigerant pipe 29 from detaching from the receiving groove 284. On the other hand, this prevents the angle at which the deformable rib 286 bends towards the refrigerant pipe 29 from being too large, thus avoiding or mitigating the problem of breakage due to bending at the connection between the deformable rib 286 and the second heat sink 28.

[0193] In some embodiments of this disclosure, after the refrigerant pipe 29 is pressed into the receiving groove 284, in the first direction, as shown in Figures 17 and 18, the farthest 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, where L2 < A2. This allows the refrigerant pipe 29 to deform after being pressed into the depth direction of the receiving groove 284, facilitating the fitting of the refrigerant pipe 29 with the receiving groove 284 after deformation. After deformation, the refrigerant pipe 29 is confined within the receiving groove 284, preventing the refrigerant pipe 29 from detaching from the connection with the receiving groove 284.

[0194] It should be noted that after the refrigerant pipe 29 is deformed by pressure, the side of the refrigerant pipe 29 away from the bottom of the receiving tank 284 is not limited to the plane shown in Figure 18, but can also be an arc-shaped surface, etc., depending on the specific situation.

[0195] In some embodiments of this disclosure, the outer diameter of the refrigerant pipe 29 before it is pressed is the same as the outer diameter of the bend section, and the outer diameter of the bend section is A2, where A2≥7mm and A2≤12.7mm.

[0196] In some embodiments of this disclosure, A2 has a lower limit value, and A2 cannot be less than the lower limit value. When A2 is less than the lower limit value, the diameter of the refrigerant pipe 29 needs to be customized and is not universal. If the diameter of the refrigerant pipe 29 is too small, the refrigerant pipe 29 will not be able to perform the throttling function. The lower limit value of A2 can be 7mm.

[0197] In some embodiments of this disclosure, A2 has an upper limit value, and A2 cannot exceed this upper limit value. When A2 exceeds the upper limit value, the diameter of the refrigerant pipe 29 needs to be customized, lacking versatility. An excessively large diameter of the refrigerant pipe 29 will result in a larger size occupied by the refrigerant pipe 29, leading to an excessively large size of the second heat sink. Furthermore, an excessively large diameter of the refrigerant pipe 29 will prevent it from achieving a proper throttling effect. The upper limit value of A2 can be 12.7 mm.

[0198] In some embodiments of this disclosure, A2 can be 8mm. On the one hand, this ensures that the diameter of the refrigerant pipe 29 meets the national standard metric and imperial dimensions, preventing the refrigerant pipe 29 from being too small and thus failing to achieve its throttling function. On the other hand, 7mm, 7.94mm, 8mm, 9.52mm, 9.53mm, 12mm, or 12.7mm are national standard metric and imperial dimensions, ensuring that the diameter of the refrigerant pipe 29 meets the national standard metric and imperial dimensions, preventing the refrigerant pipe 29 from being too large, and facilitating the universal assembly of the refrigerant pipe 29.

[0199] In some embodiments of this disclosure, referring to Figures 14, 15, and 17, the width of the opening of the receiving groove 284 is defined as B2. The outer diameter of the straight pipe section 291 before compression is the same as the outer diameter A2 of the bent pipe section 292, where B2 / A2 ≥ 1.03 and B2 / A2 ≤ 1.15.

[0200] In some embodiments of this disclosure, B2 / A2 has a lower limit value, which cannot be less than the lower limit value. When B2 / A2 is less than the lower limit value, the width of the opening of the receiving groove 284 may be too small for the length of the outer diameter of the refrigerant pipe 29 before it is pressed. This prevents the refrigerant from being directly placed into the receiving groove 284 through the opening, resulting in low assembly efficiency between the refrigerant pipe 29 and the receiving groove 284. This could cause the refrigerant pipe 29 to be squeezed and ruptured. The lower limit value of B2 / A2 can be 1.03.

[0201] In some embodiments of this disclosure, B2 / A2 has an upper limit value, and B2 / A2 cannot exceed this upper limit value. When B2 / A2 exceeds this upper limit value, the width of the opening of the receiving groove 284 may be too large relative to the outer diameter of the refrigerant pipe 29 before it is pressed in. This would cause the refrigerant pipe 29 to move around within the receiving groove 284 after it is pressed in, which is not conducive to confining the refrigerant pipe 29 within the receiving groove 284. The upper limit value of B2 / A2 can be 1.15.

[0202] In some embodiments of this disclosure, B2 / A2 can be 1.11. On the one hand, this ensures that the width of the opening of the receiving groove 284 is not less than the length of the outer diameter of the refrigerant pipe 29 before being pressed, allowing the refrigerant pipe to be directly inserted into the receiving groove 284 through the opening. This avoids the problem that the refrigerant pipe 29 cannot pass through the receiving groove 284 along its length extension direction, ensuring that even if the refrigerant pipe 29 is deformed or bent, it can still be inserted into the receiving groove 284, improving the assembly efficiency of the refrigerant pipe 29 and the receiving groove 284, and also ensuring the fit strength between the refrigerant pipe 29 and the receiving groove 284 after pressing. On the other hand, this ensures that the width of the opening of the receiving groove 284 is not too large relative to the length of the outer diameter of the refrigerant pipe 29 before being pressed, ensuring the fit strength between the refrigerant pipe 29 and the receiving groove 284 after pressing, preventing the refrigerant pipe 29 from detaching from the receiving groove 284.

[0203] In some embodiments of this disclosure, referring to Figures 12, 14, 15 and 17, the second heat sink 28 includes at least two receiving slots 284, the distance between the centers of two adjacent receiving slots 284 is C2, C2 / A2≥1, C2 / A2≤10.

[0204] In some embodiments of this disclosure, C2 / A2 has a lower limit value, and C2 / A2 cannot be less than the lower limit value. When C2 / A2 is less than the lower limit value, the distance between two adjacent receiving slots 284 may be too small, and the bending process of the refrigerant pipe 29 cannot meet this spacing, making it inconvenient to place the bent refrigerant pipe 29 into the two adjacent receiving slots 284. The lower limit value of C2 / A2 can be 1.

[0205] In some embodiments of this disclosure, C2 / A2 has an upper limit value, which cannot exceed. When C2 / A2 exceeds the upper limit, the distance between two adjacent receiving slots 284 becomes too large, resulting in an excessively large space occupied by the second heat sink 28 and an excessively large distance between adjacent refrigerant pipes 29. This reduces the effectiveness of the refrigerant heat sink and prevents effective heat dissipation for the power module 26. The upper limit value of C2 / A2 can be 10.

[0206] In some embodiments of this disclosure, C2 / A2 can be 5. On the one hand, this ensures that the distance between two adjacent receiving slots 284 is not too small, guaranteeing that the bent refrigerant pipe 29 can be smoothly placed into the two adjacent receiving slots 284. On the other hand, this ensures that the distance between two adjacent receiving slots 284 is not too large, preventing the space occupied by the second heat sink 28 from becoming too large, and also preventing the distance between adjacent refrigerant pipes 29 from becoming too large, thereby improving the heat dissipation effect of the refrigerant radiator.

[0207] In some embodiments of this disclosure, referring to Figures 14, 15 and 17, the shortest distance from the opening 2841 of the receiving groove 284 to the edge of the second heat sink 28 is defined as D2, where D2 / A2≥0.25 and D2 / A2≤0.5, in the width direction of the receiving groove 284.

[0208] In some embodiments of this disclosure, D2 / A2 has a lower limit value, which cannot be less than the lower limit value. When D2 / A2 is less than the lower limit value, the shortest distance D2 between the opening 2841 of the receiving groove 284 and the edge of the second heat sink 28 is too small. This results in a smaller strength of the portion D2 of the second heat sink 28 when the refrigerant pipe 29 is pressed into the receiving groove 284. The second heat sink 28 deforms under stress, which in turn affects the fit and heat dissipation effect between the refrigerant pipe 29 and the receiving groove 284. The lower limit value of D2 / A2 can be 0.25.

[0209] In some embodiments of this disclosure, D2 / A2 has an upper limit value, and D2 / A2 cannot exceed this upper limit value. When D2 / A2 exceeds this upper limit value, the shortest distance D2 between the opening 2841 of the receiving slot 284 and the edge of the second heat sink 28 becomes too large, resulting in an excessively large space occupied by the second heat sink 28. This reduces the effectiveness of the refrigerant heat sink and prevents effective heat dissipation for the power module 26. The upper limit value of D2 / A2 can be 0.5.

[0210] In some embodiments of this disclosure, D2 / A2 can be 0.3, which makes the shortest distance D2 between the opening 2841 of the receiving groove 284 and the edge of the second heat sink 28 appropriate. This ensures that when the refrigerant pipe 29 is pressed into the receiving groove 284, the portion of the second heat sink 28 with size D2 has sufficient strength to prevent deformation of the second heat sink 28, thereby ensuring that the portion of the second heat sink 28 with size D2 does not deform, and improving the fit and heat dissipation effect between the refrigerant pipe 29 and the receiving groove 284.

[0211] In some embodiments of this disclosure, referring to Figures 12, 14, 15 and 17, 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 sink 28 is E2, where E2 / A2≥0.25 and E2 / A2≤0.5.

[0212] In some embodiments of this disclosure, E2 / A2 has a lower limit value, which cannot be less than the lower limit value. When E2 / A2 is less than the lower limit value, the shortest distance E2 between the bottom of the receiving groove 284 and the bottom of the second heat sink 28 is too small. This causes the second heat sink 28 to be squeezed by the refrigerant pipe 29 when it is pressed into the receiving groove 284. The portion of the second heat sink 28 with a size of E2 does not have sufficient strength to prevent deformation of the second heat sink 28, which will cause deformation of the portion of the second heat sink 28 with a size of E2, affecting the fit 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.

[0213] In some embodiments of this disclosure, E2 / A2 has an upper limit value, and E2 / A2 cannot exceed this upper limit value. When E2 / A2 exceeds this upper limit value, the shortest distance D2 between the opening 2841 of the receiving slot 284 and the edge of the second heat sink 28 may become too large, resulting in an excessively large space occupied by the second heat sink 28 in the first direction. This would reduce the effectiveness of the refrigerant heat sink and prevent effective heat dissipation for the power module 26. The upper limit value of E2 / A2 can be 0.5.

[0214] In some embodiments of this disclosure, E2 / A2 can be 0.3, which makes the shortest distance E2 between the bottom of the receiving groove 284 and the bottom of the second heat sink 28 appropriate. This ensures that when the refrigerant pipe 29 is pressed into the receiving groove 284, the portion of the second heat sink 28 with size E2 has sufficient strength to prevent deformation of the second heat sink 28, thereby ensuring that the portion of the second heat sink 28 with size E2 does not deform, and improving the fit and heat dissipation effect between the refrigerant pipe 29 and the receiving groove 284.

[0215] In some embodiments of this disclosure, referring to Figures 12, 14, 15 and 17, the maximum depth dimension of the receiving groove 284 in the depth direction is F2. In some embodiments, F2 / A2≥0.5 and F2 / A2≤1.

[0216] In some embodiments of this disclosure, F2 / A2 has a lower limit value, and F2 / A2 cannot be less than the lower limit value. When F2 / A2 is less than the lower limit value, most of the refrigerant pipe 29 cannot be placed in the receiving groove 284, making it easy for the refrigerant pipe 29 to detach from the receiving groove 284, which is inconvenient for fixing and restricting the refrigerant pipe 29. The lower limit value of F2 / A2 can be 0.5.

[0217] In some embodiments of this disclosure, F2 / A2 has an upper limit value, and F2 / A2 cannot exceed this upper limit value. When F2 / A2 exceeds this upper limit value, the refrigerant pipe 29 can be completely contained within the receiving groove 284, requiring the deformable rib to be bent at a large angle to abut against the refrigerant pipe 29. This is detrimental to the deformable rib's contact with and fixation of the refrigerant pipe 29, and excessive bending of the deformable rib will also affect its structural strength. The upper limit value of F2 / A2 can be 1.

[0218] In some embodiments of this disclosure, F2 / A2 can be 0.8, which facilitates the deformation of the refrigerant pipe 29 after it is pressed into the depth direction of the receiving groove 284, and facilitates the fitting of the refrigerant pipe 29 with the receiving groove 284 after deformation. After the refrigerant pipe 29 is deformed, the deformation rib bends and abuts against the refrigerant pipe to confine the refrigerant pipe 29 within the receiving groove 284, preventing the refrigerant pipe 29 from detaching from the receiving groove 284. The refrigerant pipe 29 can be confined and fixed by bending the deformation rib.

[0219] In this disclosure, after the refrigerant pipe 29 is deformed, the refrigerant pipe 29 is confined within the receiving groove 284, which can prevent the refrigerant pipe 29 from detaching from the connection with the receiving groove 284.

[0220] In some embodiments of this disclosure, a manufacturing tool for pressing the refrigerant pipe 29 may be provided, and a protrusion adapted to the deformation groove 287 is provided on one side of the manufacturing tool. The protrusion is inserted into the deformation groove 287, and the manufacturing tool presses the refrigerant pipe 29 toward the second heat sink 28 to press the refrigerant pipe 29 into the receiving groove 284.
