[0062] The present application embodiment provides an electric control box 10, see Figure 1 , Figures 5 to 8 , Fig.10 The electric control box 10 includes a first box body 11, an electric control board 12 and an inductor assembly 13.

[0063] The first box body 11 has a first air duct 11a and a first air inlet 11b, an air outlet 11c and a first avoidance port 112b which are respectively connected to the first air duct 11a. The first avoidance port 112b is arranged on one side of the first air duct 11a along the first direction of the electric control box and is located between the first air inlet 11b and the air outlet 11c. The first air inlet 11b faces the inner wall of the first air duct 11a.

[0064] The first air duct 11a is a passage for air flow. The first air inlet 11b is an entrance for air flow from the outside to enter the first air duct 11a. The air outlet 11c is an outlet for air flow to flow out of the first air duct 11a.

[0065] The relative positions of the first air inlet 11b and the air outlet 11c are not limited. For example, please refer to Figures 5 to 8 The first air inlet 11b and the air outlet 11c may be respectively located at opposite sides of the first air duct 11a along a second direction perpendicular to the first direction.

[0066] The first air inlet 11b facing the inner wall of the first air duct 11a means that on the projection plane parallel to the first air inlet 11b, the projection of the first air inlet 11b is located within the projection area of ​​the inner wall of the first air duct 11a, or in other words, after the external air flow enters the first air inlet 11b, it flows toward the inner wall of the first air duct 11a.

[0067] On the premise that the first air inlet 11b faces the inner wall of the first air duct 11a, the first air inlet 11b can be located on a side of the first air duct 11a away from the electric control board 12, or on other sides of the first air duct 11a.

[0068] For example, see Figures 5 to 8 , Fig.10The first box body 11 may include a first shell 111 and a second shell 112 . The second shell 112 is disposed on one side of the first shell 111 along the first direction and forms a first air duct 11 a with the first shell 111 .

[0069] The first air inlet 11b may be disposed in the first housing 111, and the first avoidance opening 112b may be disposed in the second housing 112. Figure 6 The air outlet 11c shown is disposed on the second shell 112. In other embodiments, the air outlet 11c may also be disposed on the first shell 111, or the first shell 111 and the second shell 112 may also be provided with the air outlet 11c respectively.

[0070] The first housing 111 and the second housing 112 may be made of the same material or different materials.

[0071] For the first shell 111 and the second shell 112 made of different materials, for example, the first shell 111 may be made of metal, the second shell 112 may be made of plastic, and the second shell 112 may be arranged in the first shell 111. The second shell 112 made of plastic can play a certain role in insulation, while the first shell 111 made of metal can play a certain role in fire prevention and explosion prevention. Therefore, the combination of the first shell 111 made of metal and the second shell 112 made of plastic can improve the safety of the electric control box.

[0072] See also Figures 6 to 8 The electric control board 12 may be disposed on a side of the second housing 112 that is away from the first housing 111 .

[0073] In other embodiments, the first box body 11 may also have only one shell.

[0074] See also Figure 1 , Figures 6 to 8 The electric control box 10 may also be provided with an openable and closable second box body 17 , and the electric control board 12 may be provided in the second box body 17 , that is, after the second box body 17 is opened, the electric control board 12 , the inductor assembly 13 and the heat sink 14 are all located in the second box body 17 .

[0075] In some other embodiments, the electric control board 12 may also be disposed in the first box body 11 , that is, after the second box body 17 is opened, the electric control board 12 , the inductor assembly 13 and the heat sink 14 are all located in the first box body 11 .

[0076] The structure of the second box body 17 is not limited, for example, please refer to Figure 1 The second box body 17 may include a third shell 171 and a fourth shell 172 . The fourth shell 172 is disposed on a side of the third shell 171 close to the first box body 11 . The electric control board 12 may be disposed in the fourth shell 172 .

[0077] That is to say, the third shell 171 and the fourth shell 172 can be integrally formed or can be a split structure, and the third shell 171 and the fourth shell 172 can be made of the same material or different materials.

[0078] For the third shell 171 and the fourth shell 172 made of different materials, illustratively, the third shell 171 may be made of metal, and the fourth shell 172 may be made of plastic.

[0079] In other embodiments, the second box body 17 may also have only one shell.

[0080] Please continue reading Figures 6 to 8 The inductor assembly 13 is disposed on the electric control board 12. The inductor assembly 13 includes an inductor element 131 electrically connected to the electric control board 12. At least a portion of the structure of the inductor element 131 extends from the first avoidance opening 112b into the first air duct 11a. The side of the inductor element 131 away from the electric control board 12 along the first direction is suspended in the air, that is, the side of the inductor element 131 away from the electric control board 12 along the first direction does not contact the inner side wall of the first air duct 11a.

[0081] In addition, it should be noted that the setting position of the first avoidance opening 112b should ensure as much as possible that the portion of the inductor element 131 extending into the first air duct 11a can be staggered with the first air inlet 11b, that is, on the projection plane parallel to the first air inlet 11b, the projection of the portion of the inductor element 131 located in the first air duct 11a is located outside the projection of the first air inlet 11b, or in other words, after the airflow enters the first air inlet 11b, it will not flow directly toward the portion of the inductor element 131 located in the first air duct 11a.

[0082] The present application also provides a head assembly, see Figures 1 to 4 The head assembly includes a water receiving tray 20, a cover shell 30 and an electric control box 10 provided in any embodiment of the present application.

[0083] The housing 30 is disposed on one side of the water receiving tray 20, and has a mounting cavity 30a and an airflow inlet 30b and an airflow outlet 30c respectively connected to the mounting cavity 30a, and an airflow path is formed between the airflow inlet 30b and the airflow outlet 30c. The electric control box 10 is disposed in the mounting cavity 30a and is located on the airflow path, and the electric control board 12 is located on the side of the inductor assembly 13 away from the water receiving tray 20.

[0084] The structure of the housing 30 is not limited, for example, see Figure 1The housing 30 may include a housing 31 and a top cover 32 disposed on the top of the housing 31, wherein the housing 31 has an airflow inlet 30b and an airflow outlet 30c. To facilitate assembly and maintenance of the head assembly, the top cover 32 and the housing 31 may be detachably connected. In another embodiment, the top cover 32 and the housing 31 may also be an integrated structure.

[0085] See also Figure 1 , Figure 3 and Figure 4 The head assembly also includes a heat exchanger 40 and a compressor 50 arranged in the installation cavity 30a, the air flow inlet 30b and the air flow outlet 30c are respectively located on opposite sides of the heat exchanger 40, the compressor 50 can be located on the side of the heat exchanger 40 close to the air flow inlet 30b, and the electric control box 10 is located on the side of the compressor 50 away from the water receiving tray 20.

[0086] During the operation of the head assembly, the external airflow enters the installation cavity 30a through the airflow inlet 30b to exchange heat with the heat exchanger 40. During this process, the heat exchanger 40 will produce condensed water, and the water receiving tray 20 can receive the condensed water produced by the heat exchanger 40. By arranging the electric control box 10 on the side of the compressor 50 away from the water receiving tray 20, the probability of condensed water entering the electric control box 10 can be reduced.

[0087] See also Figure 4 The head assembly may include a support member 60 and a wind wheel bracket 70. The support member 60 is arranged on a side of the heat exchanger 40 close to the air flow inlet 30b, and the wind wheel bracket 70 is arranged on a side of the heat exchanger 40 away from the support member 60. The electric control box 10 is connected to the wind wheel bracket 70 and the support member 60 respectively.

[0088] The wind wheel bracket 70 and the support member 60 can support the electric control box 10 to improve the installation stability of the electric control box 10 .

[0089] The wind wheel bracket 70 is used to install the wind wheel. The wind wheel bracket 70 is arranged on the side of the heat exchanger 40 away from the support member 60, that is, the wind wheel bracket 70 is located downstream of the heat exchanger 40 along the airflow path and on the side of the heat exchanger 40 close to the airflow outlet 30c.

[0090] See also Figure 1 , Figure 3 and Figure 4 The head assembly may further include a fan box 80 , which is disposed on a side of the heat exchanger 40 away from the air flow outlet 30 c , and one side of the electric control box 10 may be connected to the fan box 80 .

[0091] The electric control box 10 is located on the airflow path, which means that part of the airflow entering the installation cavity 30a from the airflow inlet 30b can enter the first air duct 11a from the first air inlet 11b of the first air duct 11a to dissipate heat for the inductor 131 .

[0092] The electric control board 12 is located on the side of the inductor assembly 13 away from the water receiving tray 20, that is, the first avoidance opening 112b is located at the top of the first air duct 11a, and the inductor assembly 13 is equivalent to extending into the first air duct 11a from the top of the first air duct 11a.

[0093] An embodiment of the present application further provides a heat pump water heater, which includes a water tank assembly and a head assembly provided by any embodiment of the present application, wherein the head assembly is disposed on the water tank assembly.

[0094] The head assembly is generally disposed at the top of the water tank assembly along the height direction. In other embodiments, the head assembly may also be disposed at other positions of the water tank assembly.

[0095] The water tank assembly comprises an outer shell, an inner tank and a water tank heat exchanger arranged in the outer shell. The inner tank is used to store domestic water. The water tank heat exchanger can heat the domestic water in the inner tank into hot water by exchanging heat with the heat exchanger in the head assembly.

[0096] See also Figure 6 and Figure 8 The inductor element 131 generates a lot of heat when working. By making at least part of the structure of the inductor element 131 located in the first air duct 11a, the airflow can exchange heat with the inductor element 131 when flowing in the first air duct 11a and take away the heat, thereby improving the heat dissipation effect of the electric control box 10. In addition, in some cases, rainwater, condensation water and other liquids outside the electric control box 10 may enter the first air duct 11a from the first air inlet 11b. Therefore, the first air inlet 11b faces the inner wall of the first air duct 11a, and the inner wall can play a certain blocking role for rainwater, condensation water and other liquids entering the first air duct 11a. At the same time, since the inductor element 131 is suspended in the first direction away from the side of the electric control board 12, that is, the side of the inductor element 131 close to the water receiving tray 20 is suspended in the first air duct 11a, even if rainwater, condensation water and other liquids enter the first air duct 11a, it is difficult to directly contact the inductor element 131. Therefore, the electric control box 10 of the embodiment of the present application has better waterproof performance while improving the heat dissipation effect of the inductor element 131.

[0097] Also, see Figure 4When the first air inlet 11b is arranged on the side of the first air duct 11a away from the electric control board 12, the first air inlet 11b is actually facing the water receiving tray 20, and it is difficult for liquids such as rainwater and condensed water to enter the first air duct 11a from the first air inlet 11b. Even if liquids such as rainwater and condensed water enter the first air duct 11a from the first air inlet 11b, at least part of the rainwater and condensed water can also drip from the first air inlet 11b to the water receiving tray 20 under the action of their own gravity. Therefore, the probability of liquids such as rainwater and condensed water entering the first air duct 11a from the first air inlet 11b can be further reduced.

[0098] It should be noted that when the electric control box 10 is arranged in the head assembly, the installation method of the electric control box 10 in the head assembly is not limited to placing the electric control board 12 of the electric control box 10 on the side of the inductor assembly 13 away from the water receiving tray 20. According to the specific design method, the electric control box 10 can also adopt other installation methods. For example, the electric control board 12 can also be placed on the side of the inductor assembly 13 away from the heat exchanger 40.

[0099] In addition, the electric control box 10 of the embodiment of the present application is not limited to being used in heat pump water heaters, and the electric control box can be used in any other electrical equipment that requires an electric control box.

[0100] In one embodiment, please refer to Figure 6 The first air inlet 11b and the air outlet 11c can be respectively located on opposite sides of the first air duct 11a along a second direction perpendicular to the first direction. The first air duct 11a includes a first sub-channel 11a1 connected to the first air inlet 11b and an inductor accommodating cavity 11a3 connected to the first sub-channel 11a1 through a first air passage 11a2. The first avoidance port 112b is connected to the inductor accommodating cavity 11a3, that is, the inductor element 131 extends into the inductor accommodating cavity 11a3.

[0101] The first air inlet 11b and the air outlet 11c are respectively located on opposite sides of the first air duct 11a along the second direction, which means that the first air inlet 11b and the air outlet 11c can be located on opposite sides of the first air duct 11a, or can be located near the opposite sides of the first air duct 11a. Figure 6 The first air inlet 11b is shown located near one side of the first air duct 11a along the second direction, and the air outlet 11c is located on one side of the first air duct 11a along the second direction, that is, the first air inlet 11b and the air outlet 11c are not arranged in parallel.

[0102] The inductor accommodating cavity 11 a 3 is used to accommodate at least a part of the structure of the inductor element 131 , and the airflow exchanges heat with the inductor element 131 when flowing through the inductor accommodating cavity 11 a 3 .

[0103] Figure 6 and Figure 8 The inductor receiving cavity 11a3 is shown to be located on the side of the first sub-channel 11a1 close to the electric control board 12, and the first air outlet 11a2 is located on the side of the first air inlet 11b close to the air outlet 11c along the second direction. In other words, the inductor receiving cavity 11a3 is closer to the electric control board 12 than the first sub-channel 11a1, thereby not only allowing as much structure of the inductor element 131 as possible to extend into the inductor receiving cavity 11a3, but also reducing the probability of liquids such as rainwater entering the inductor receiving cavity 11a3 from the first sub-channel 11a1.

[0104] Please continue reading Figure 6 and Figure 8 The first sub-channel 11a1 may include a first channel section 11a11 and a second channel section 11a12, the first channel section 11a11 is located on a side of the second channel section 11a12 away from the air outlet 11c along the second direction, and a side of the first channel section 11a11 close to the electric control board 12 protrudes from the second channel section 11a12, the first channel section 11a11 is communicated with the first air inlet 11b, the inductor accommodating cavity 11a3 is located on a side of the second channel section 11a12 close to the electric control board 12, and the inductor accommodating cavity 11a3 is communicated with the second channel section 11a12 through the first air outlet 11a2.

[0105] When the airflow flows in the first sub-channel 11a1, it first enters the first channel section 11a11 from the first air inlet 11b, then enters the second channel section 11a12, and then enters the inductor accommodating cavity 11a3 through the first air outlet 11a2 to exchange heat with the inductor element 131.

[0106] The side of the first channel section 11a11 close to the electric control board 12 protrudes from the second channel section 11a12, that is, the side wall at the connection point of the first channel section 11a11 and the second channel section 11a12 forms a step-like structure, which can prevent rainwater from entering the inductor accommodating cavity 11a3 from the second channel section 11a12, thereby reducing the probability of rainwater entering the motor accommodating cavity from the first sub-channel 11a1.

[0107] For example, please refer to Figure 6 and Figure 8 The first box body 11 may have a convex portion 1121 located in the first channel section 11a11, the convex portion 1121 is arranged between the second channel section 11a12 and the first air inlet 11b, and extends in the direction close to the electric control board 12 to construct a second air outlet 1121a in the first channel section 11a11, the second air outlet 1121a is located on a side of the convex portion 1121 close to the electric control board 12, that is, the convex portion 1121 is located on a side of the first air duct 11a close to the first air inlet 11b along the first direction, which can prevent liquids such as rainwater and condensed water from entering the second channel section 11a12.

[0108] For the embodiment in which the first box body 11 includes the first shell 111 and the second shell 112 , the protrusion 1121 may be a part of the second shell 112 or a part of the first shell 111 .

[0109] In one embodiment, please refer to Figure 6 and Figure 8 The first air inlet 11b and the air outlet 11c can be respectively located on opposite sides of the first air duct 11a along a second direction perpendicular to the first direction. The first air duct 11a includes an inductor accommodating cavity 11a3 and a second sub-channel 11a5 connected to the inductor accommodating cavity 11a3 through a third air outlet 11a4. The second sub-channel 11a5 is located on a side of the inductor accommodating cavity 11a3 away from the first air inlet 11b along the second direction, and extends in a direction away from the electric control board 12.

[0110] The second sub-channel 11a5 is located on the side of the inductor housing away from the first air inlet 11b along the second direction, that is, the second sub-channel 11a5 is located on the side of the inductor housing close to the air outlet 11c along the second direction. When the airflow flows in the first air duct 11a, it enters the second sub-channel 11a5 from the inductor housing cavity 11a3 through the third air outlet 11a4.

[0111] The second sub-channel 11a5 extends in a direction away from the electric control board 12, that is, the airflow flows in the second sub-channel 11a5 in a direction away from the electric control board 12, and thus flows toward the air outlet 11c. This structure can further reduce the probability of liquids such as rainwater and condensed water entering the inductor accommodating cavity 11a3 from the air outlet 11c.

[0112] For example, see Figure 6 and Figure 8 The third air inlet 11a4 and the air outlet 11c may be respectively located at two opposite sides of the second sub-channel 11a5 along the second direction, and the third air inlet 11a4 and the air outlet 11c are staggered.

[0113] The third air vent 11a4 and the air outlet 11c are staggered in that there is no overlapping area between the projections of the third air vent 11a4 and the air outlet 11c on the projection plane perpendicular to the second direction, thereby reducing the probability of liquids such as rainwater and condensed water entering the inductor housing cavity 11a3 from the second sub-channel 11a5.

[0114] Figure 1 and Figure 4 In the head assembly shown, the inductor assembly 13 is arranged on the side of the compressor 50 away from the water receiving tray 20, and the third air outlet 11a4 can be farther away from the water receiving tray 20 than the air outlet 11c. Liquids such as rainwater and condensed water cannot enter the inductor accommodating cavity 11a3 from the third air outlet 11a4 under the action of gravity, thereby enhancing the waterproofness of the electronic control box 10.

[0115] In one embodiment, please refer to Figures 4 to 6 , Figure 8 and Fig.10 The first box body 11 may have a first air guide plate 1111 arranged outside the first air inlet 11b.

[0116] For the embodiment in which the first box body 11 includes a first shell body 111 and a second shell body 112 , the first air guide plate 1111 may be disposed on the first shell body 111 .

[0117] The first air guide 1111 is used to increase the amount of air entering the first air duct 11a. The first air guide 1111 may be located on a side of the first air inlet 11b close to the air outlet 11c along the second direction, and tilted toward the direction close to the first air inlet 11b. When the airflow flows to the first air guide 1111, it may enter the first air duct 11a from the first air inlet 11b along the first air guide 1111.

[0118] See also Figure 4 The first air guide plate 1111 may be located on a side of the first air inlet 11b away from the air flow inlet 30b along the air flow path.

[0119] The inclination angle of the first air guide 1111 is not limited, preferably, the inclination angle of the first air guide 1111 is 10° to 90° (including the end values). It should be noted that the inclination angle of the first air guide 1111 refers to the angle between the first air guide 1111 and the plane where the first air inlet 11b is located.

[0120] In addition, the first air guide piece 1111 can also play a certain role in blocking water, thereby further reducing the probability of liquids such as rainwater and condensed water entering the first air duct 11a from the first air inlet 11b.

[0121] In one embodiment, please refer to Figure 1 , Figure 6 and Figure 7 The electric control box 10 may include a heat sink 14 disposed on the electric control board 12 , and the air outlet 11 c faces the heat sink 14 .

[0122] The heat sink 14 is used to dissipate heat for the electric control board 12. The heat sink 14 is disposed on the electric control board 12, so that the heat generated by the electric control board 12 can be transferred to the heat sink 14, and the airflow flowing out of the air outlet 11c can flow to the heat sink 14 and exchange heat with the heat sink 14, thereby completing the heat dissipation of the electric control board 12. By making the air outlet 11c face the heat sink 14, the heat dissipation effect of the heat sink 14 can be improved.

[0123] For example, see Figure 7The first box body 11 may have a second air duct 11d and a second air inlet 11e, and the second air duct 11d is connected to the second air inlet 11e and the air outlet 11c respectively.

[0124] The second air duct 11d is used to increase the airflow to the heat sink 14. The airflow can enter the second air duct 11d from the second air inlet 11e and then flow to the heat sink 14 from the air outlet 11c, thereby improving the heat dissipation effect of the heat sink 14.

[0125] For the embodiment in which the first box body 11 includes a first shell 111 and a second shell 112 , the first shell 111 and the second shell 112 may jointly enclose a second air duct 11 d , and the second air inlet 11 e may be disposed in the first shell 111 .

[0126] See also Figures 5 to 8 The second air duct 11d and the first air duct 11a can be located on the same side of the air outlet 11c along the second direction, and the second air duct 11d is located on one side of the first air duct 11a along the third direction, and the third direction is perpendicular to the first direction and the second direction respectively, which can simplify the structure of the electric control box 10 and make the setting position of the first air duct 11a and the second air duct 11d more compact.

[0127] Please continue reading Figures 5 to 8 The first air duct 11a and the second air duct 11d may be separated, a portion of the air outlet 11c is communicated with the first air duct 11a, and another portion of the air outlet 11c is communicated with the second air duct 11d.

[0128] Separation means that the first air duct 11a and the second air duct 11d are not connected, and the airflow can only enter one of the first air duct 11a and the second air duct 11d, thereby ensuring the heat dissipation effect of the inductor element 131 and the heat sink 14 at the same time.

[0129] In another embodiment, parts of the first air duct 11a and the second air duct 11d may be connected, for example, the first air duct 11a and the second air duct 11d are connected at one end near the air outlet 11c. Figure 5 and Figure 7 The first box body 11 may have a second air guide plate 1112 arranged outside the second air inlet 11e.

[0130] For the embodiment in which the first box body 11 includes a first shell body 111 and a second shell body 112 , the second air guide plate 1112 may be disposed on the first shell body 111 .

[0131] The second air guide 1112 is used to increase the airflow entering the second air duct 11d. The second air guide 1112 may be located on a side of the second air inlet 11e close to the air outlet 11c along the second direction, and tilted toward the direction close to the second air inlet 11e. When the airflow flows to the second air guide 1112, it may enter the second air duct 11d from the second air inlet 11e along the second air guide 1112.

[0132] The inclination angle of the second air guide blade 1112 may be the same as the inclination angle of the first air guide blade 1111 .

[0133] In addition, the second air guide piece 1112 can also play a certain role in blocking water, so as to prevent rainwater, condensed water and other liquids from entering the second air duct 11d from the second air inlet 11e.

[0134] In one embodiment, please refer to Figure 7 and Fig.10 The first box body 11 may have a communication port 112a that penetrates the first box body 11 along the first direction. The heat sink 14 is disposed in the communication port 112a and extends to the outside of the first box body 11 through the communication port 112a, which can further enhance the heat dissipation effect of the heat sink 14.

[0135] For the embodiment in which the first box body 11 includes a first shell 111 and a second shell 112, the second shell 112 can have a connecting port 112a that penetrates the second shell 112 along the first direction, the first shell 111 has a second avoiding port 111a that avoids the connecting port 112a, and the heat sink 14 is arranged in the connecting port 112a and the second avoiding port 111a, and extends to the outside of the first box body 11 through the second avoiding port 111a.

[0136] For example, see Figure 4 The air outlet 11c can be located on the side of the heat sink 14 away from the heat exchanger 40, and at least toward the portion of the heat sink 14 located outside the first box body 11. In other words, the airflow from the air outlet 11c can directly flow to the portion of the heat sink 14 located outside the first box body 11, so as to improve the heat dissipation effect of the heat sink 14.

[0137] Taking the heat sink 14 as an example, which includes a plurality of heat sinks arranged at intervals, a heat dissipation channel for airflow to pass through is formed between adjacent heat sinks, and the angle between each heat sink and the evaporator can be 70° to 90° (including the endpoint values), so that the airflow flowing out of the heat dissipation channel can flow to the heat exchanger 40 more smoothly, thereby increasing the heat exchange efficiency of the heat exchanger 40.

[0138] In one embodiment, please refer to Figure 8 , Fig. 9 and Fig.11The inductor assembly 13 may include a base 132 with an installation opening, the base 132 is arranged on the electric control board 12, and a part of the structure of the inductor element 131 is located in the installation opening. The electric control box 10 includes a sealing assembly 15, and the sealing assembly 15 includes a first sealing ring 151 and a second sealing ring 152. The first sealing ring 151 is sleeved on the outer peripheral side of the inductor element 131, and is in sealing contact with the part of the base 132 located on the side of the installation opening and the first box body 11 respectively, and the second sealing ring 152 is sleeved on the outer peripheral side of the heat sink 14, and is in sealing contact with the first box body 11. In other words, the inductor assembly 13 and the first box body 11, as well as the heat sink 14 and the first box body 11, are sealed by respectively arranging sealing rings.

[0139] The base 132 is used to install the inductor 131. For example, the pins of the inductor 131 can be fixed on the base 132, and then the base 132 is directly plugged into the electric control board 12 to achieve electrical connection between the inductor 131 and the electric control board 12.

[0140] The material of the first sealing ring 151 and the second sealing ring 152 is not limited. For example, the first sealing ring 151 and the second sealing ring 152 can be made of rubber, silicone and other materials with certain elasticity and compressibility. The first sealing ring 151 and the second sealing ring 152 made of rubber, silicone and other materials not only have good sealing performance, but also can improve the assembly tolerance through their own elastic deformation, thereby achieving stable sealing.

[0141] For example, see Figure 8 and Fig. 9 The electric control box 10 includes a second housing 112. The electric control box 10 may have an installation space located on a side of the second housing 112 away from the first air duct 11a, and the electric control board 12 is arranged in the installation space. The first sealing ring 151 is in sealing contact with the base 132 and the installation box respectively, so that a part of the inductor 131 can be extended into the first air duct 11a for heat dissipation, and the installation space can be sealed at the setting position of the first sealing ring 151. The second sealing ring 152 is in sealing contact with the heat sink 14 and the second housing 112 respectively, so that a part of the heat sink 14 can be extended to the outside of the installation space for heat dissipation, and the installation space can be sealed at the setting position of the second sealing ring 152.

[0142] For the embodiment in which the electric control box 10 further includes a second box body 17 , the second box body 17 is openably and closably disposed on a side of the second shell 112 away from the first shell 111 , and together with the second shell 112 , encloses an installation space, thereby facilitating maintenance of the electric control board 12 .

[0143] When the second box body 17 is in a closed state, the second box body 17 can apply a certain extrusion force to the first sealing ring 151 and the second sealing ring 152, so that the first sealing ring 151 and the second sealing ring 152 produce a certain elastic deformation under the action of the extrusion force, thereby enhancing the sealing effect and sealing stability.

[0144] Preferably, the elastic deformation of the first sealing ring 151 and the second sealing ring 152 may both be less than 2 mm.

[0145] For example, see Fig. 9 and Fig.10 The first box body 11 is located at the periphery of the first avoidance opening 112b, and the first sealing ring 151 is in sealing contact with the first avoidance opening 112b, so that the first avoidance opening 112b can be sealed. Figure 7 and Fig.10 The first box body 11 has a second avoidance opening 111a for avoiding the connecting opening 112a. The heat dissipation member 14 is passed through the connecting opening 112a and the second avoidance opening 111a, and extends to the outside of the first box body 11 through the second avoidance opening 111a. The portion of the first box body 11 located on the peripheral side of the connecting opening 112a is in sealing contact with the second sealing ring 152, so as to seal the connecting opening 112a.

[0146] See also Fig.11 and Fig.12 The sealing assembly 15 may further include a connecting member 153, which is connected to the first sealing ring 151 and the second sealing ring 152 respectively.

[0147] That is, the first sealing ring 151 and the second sealing ring 152 can be connected as a whole through the connecting piece 153, so that the assembly efficiency of the first sealing ring 151 and the second sealing ring 152 can be improved.

[0148] Preferably, the first sealing ring 151, the second sealing ring 152 and the connecting member 153 can be integrally formed.

[0149] In order to reduce the distance between the first sealing ring 151 and the second sealing ring 152, the setting position of the inductor component 13 and the setting position of the heat sink 14 can be as close as possible. For example, the distance between the inductor component 13 and the heat sink 14 can be less than 80 mm. This can reduce the size of the connector 153, which is not only beneficial to improve the reliability of the connection of the connector 153, but also beneficial to reduce the production cost of the sealing component 15.

[0150] In some other embodiments, the sealing assembly 15 may not be provided with the connecting piece 153 , that is, the first sealing ring 151 and the second sealing ring 152 are two separate sealing rings.

[0151] In one embodiment, please refer to Fig. 9 , Fig.11 and Fig.12 The first sealing ring 151 may have a first clamping portion 1511 , and the base 132 may have a second clamping portion 1321 . Fig. 9 The first clamping portion 1511 is a clamping groove, and the second clamping portion 1321 is a buckle. In another embodiment, the first clamping portion 1511 can also be a buckle, and the second clamping portion 1321 can be a clamping groove. By inserting the buckle into the clamping groove, the first sealing ring 151 can be fixed, thereby facilitating the disassembly and assembly of the first sealing ring 151 and improving the assembly efficiency of the first sealing ring 151.

[0152] It should be noted that, depending on the specific structural forms of the slots and buckles, some buckles and slots are only used to fix the first sealing ring 151 on the base 132 through snap-fitting, while some buckles and slots, in addition to being used for snap-fitting, can also play a sealing role.

[0153] For example, see Fig.11 and Fig.12 The first sealing ring 151 has a first sealing opening 151a that penetrates the first sealing ring 151, and the inductor element 131 is disposed in the first sealing opening 151a. In one embodiment, the first clamping portion 1511 can be disposed on a side of the first sealing ring 151 close to the first sealing opening 151a, that is, the first clamping portion 1511 is located in the first sealing opening 151a. The base 132 includes a mounting portion 1322 located in the first sealing opening 151a, the mounting opening penetrates the mounting portion 1322, and the second clamping portion 1321 is disposed on a side of the mounting portion 1322 that is away from the mounting opening, that is, the second clamping portion 1321 is located on the outer peripheral side of the mounting portion 1322. The inductor element 131 is disposed in the first sealing opening 151a, so that the second clamping portion 1321 can extend into the first sealing opening 151a and cooperate with the first clamping portion 1511.

[0154] See also Fig. 9 and Fig.11 The base 132 may include a seat body portion 1323 having a first sealing surface 1323a on one side, the mounting portion 1322 is arranged on the side of the seat body portion 1323 having the first sealing surface 1323a, and the first sealing surface 1323a surrounds the outer peripheral side of the mounting portion 1322, and the first sealing ring 151 is in sealing contact with the first sealing surface 1323a.

[0155] When the first sealing ring 151 is engaged with the mounting portion 1322, the first sealing surface 1323a of the seat portion 1323 is in sealing contact with the first sealing ring 151. By surrounding the first sealing surface 1323a around the outer circumference of the mounting portion 1322, the sealing stability between the first sealing ring 151 and the first sealing surface 1323a can be ensured.

[0156] Please continue reading Fig. 9 and Fig.12 The first sealing ring 151 may have a first section 1512 and a second section 1513 arranged along the penetration direction of the first sealing opening 151a, and the first section 1512 protrudes toward the inside of the first sealing opening 151a so that a second sealing surface 1512a is formed on the side of the first section 1512 close to the second section 1513, and the second sealing surface 1512a is in sealing contact with the mounting portion 1322, and a side of the first section 1512 facing away from the second section 1513 is in sealing contact with the first box body 11.

[0157] That is, the first section 1512 is in sealing contact with the base 132 and the first box body 11 at two opposite sides along the penetrating direction of the first sealing opening 151 a , respectively, so as to achieve sealing between the inductor assembly 13 and the first box body 11 .

[0158] The first section 1512 protrudes toward the inside of the first sealing opening 151 a and is in sealing contact with the mounting portion 1322 of the base 132 , thereby improving the sealing reliability of the first sealing ring 151 and the base 132 , thereby further improving the sealing stability of the electric control box 10 .

[0159] In one embodiment, please refer to Figure 8 and Fig.11 The heat sink 14 may include a heat sink body 141 and a boss 142 surrounding the outer circumference of the heat sink body 141 . The second sealing ring 152 is sleeved on the heat sink body 141 and is in sealing contact with the boss 142 .

[0160] The heat dissipation body 141 is used for heat dissipation. The type of the heat dissipation body 141 is not limited. For example, the heat dissipation body 141 may have a plurality of heat dissipation fins arranged at intervals, and air flows through the intervals between the heat dissipation fins to achieve heat dissipation.

[0161] The boss 142 is used to install the second sealing ring 152, and the second sealing ring 152 is in sealing contact with the boss 142 and the first box body 11 respectively, so as to achieve a better sealing effect.

[0162] See also Fig.11 and Fig.12 The second sealing ring 152 has a second sealing opening 152a that penetrates the second sealing ring 152, and the heat sink 14 is inserted into the second sealing opening 152a. In one embodiment, a sealing groove 152b can be provided on one side of the second sealing ring 152 close to the second sealing opening 152a, and the boss 142 can extend into the sealing groove 152b.

[0163] The sealing groove 152b is used for snap-fitting with the boss 142. The sealing groove 152b is located on the side of the second sealing ring 152 close to the second sealing opening 152a, that is, the sealing groove 152b is located on the peripheral side of the second sealing opening 152a and is in communication with the second sealing opening 152a. When the heat sink 14 is inserted into the second sealing opening 152a and the boss 142 extends into the sealing groove 152b, not only can the second sealing ring 152 be fixed on the heat sink 14, but also the second sealing ring 152 and the boss 142 can maintain stable sealing contact, thereby not only ensuring the installation stability of the second sealing ring 152, but also improving the sealing effect of the second sealing ring 152.

[0164] In other embodiments, for setting Fig.11 The electric control box 10 of the bracket 16 shown can also be a boss 142 and a bracket 16 in which at least the bracket 16 extends into the sealing groove 152b, that is, the bracket 16 and the sealing groove 152b can be snap-fitted to achieve fixation and sealing, or the boss 142 and the bracket 16 can be snap-fitted to the sealing groove 152b together to achieve fixation and sealing.

[0165] For example, see Fig.11 and Fig.12 The second sealing ring 152 may have a clamping block 1521 and a convex edge 1522 spaced apart along the penetrating direction of the second sealing opening 152a on one side thereof, and a sealing groove 152b is formed at the interval between the clamping block 1521 and the convex edge 1522 .

[0166] In addition to forming the sealing groove 152 b , the convex edge 1522 can also be used for sealing contact with the first box body 11 .

[0167] For example, see Figure 8 , Fig.11 and Fig.12 When the outer surface of the side of the convex edge 1522 away from the clamping block 1521 is flush with the end surface of the second sealing ring 152 located on the outer peripheral side of the second sealing opening 152a, the opposite sides of the convex edge 1522 along the penetration direction of the second sealing opening 152a can be sealed and contacted with the heat sink 14 and the first box body 11 respectively, thereby improving the reliability of the sealing between the second sealing ring 152 and the heat sink 14, and further improving the sealing stability of the electric control box 10.
