[0048] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0049] Hereinafter, with reference to the accompanying drawings, a heat exchange assembly 10 of an electric control box according to an embodiment of the present application will be described.

[0050] As shown in Figures 1 to 8, the heat exchange assembly 10 of the electrical control box according to an embodiment of the present application includes: a bracket 1, a first heat exchange plate 2 and a heat exchange tube 3. The bracket 1 has a mounting groove 11; the first heat exchange plate 2 is embedded in the mounting groove 11, and a first pipe groove 21 is provided on the side of the first heat exchange plate 2 away from the bracket 1; the heat exchange tube 3 is located on the side of the first heat exchange plate 2 away from the bracket 1, and the heat exchange tube 3 is embedded in the first pipe groove 21.

[0051] In this way, the installation efficiency of the heat exchange assembly 10 can be improved, and the cooling capacity of the heat exchange tube 3 can be directly diffused outward through the first heat exchange plate 2, which is beneficial to improving the cooling efficiency of the heat exchange tube 3.

[0052] First, as shown in Figure 1, the electrical control box 100 includes a housing 40, a circuit board 20, and a heat exchange assembly 10. Both the circuit board 20 and the heat exchange assembly 10 are mounted within the housing 40. As shown in Figure 2, the heat exchange assembly 10 includes a bracket 1 and a first heat exchange plate 2. The bracket 1 is connected to the housing 40 and has an upwardly open mounting slot 11. The first heat exchange plate 2 is configured to fit within the mounting slot 11. An open first conduit slot 21 is defined on the side of the first heat exchange plate 2 facing away from the bracket 1. It should be noted that the first heat exchange plate 2 is made of a material with high thermal conductivity, such as aluminum.

[0053] As shown in FIG3 , the heat exchange assembly 10 further includes a heat exchange tube 3 , which is disposed on a side of the first heat exchange plate 2 away from the bracket 1 . The heat exchange tube 3 is configured to mate with the first pipe groove 21 , and a portion of the heat exchange tube 3 can be embedded within the first pipe groove 21 to secure it to the first heat exchange plate 2 . The heat exchange tube 3 is configured as a refrigerant tube so that it can dissipate cold air outward. The cold air from the heat exchange tube 3 can be transferred to the first heat exchange plate 2 , rapidly dissipating outward through the first heat exchange plate 2 , thereby efficiently cooling the circuit board 20 . Of course, the heat exchange tube 3 can also be configured as a refrigeration component, and this application does not impose any restrictions on this.

[0054] The above arrangement improves the assembly efficiency of the heat exchange assembly 10 and reduces the transfer of cold energy between the heat exchange tubes 3 and the bracket 1, allowing the cold energy from the heat exchange tubes 3 to be directly dissipated outward through the first heat exchange plate 2, thereby improving cooling efficiency. Specifically, by providing mounting slots 11 on the bracket 1, the first heat exchange plate 2 can be pre-installed within the bracket 1, achieving the effect of pre-assembling the bracket 1 and the first heat exchange plate 2. This can then be combined with the heat exchange tubes 3, improving overall assembly efficiency.

[0055] According to the heat exchange assembly 10 of the electrical control box in the embodiment of the present application, by embedding the first heat exchange plate 2 in the bracket 1, the first heat exchange plate 2 and the bracket 1 can be pre-installed, thereby improving the installation efficiency of the heat exchange assembly 10. Moreover, by supporting the heat exchange tube 3 on the first heat exchange plate 2, the cooling capacity of the heat exchange tube 3 can be directly diffused outward through the first heat exchange plate 2, which is beneficial to improving the cooling efficiency of the heat exchange tube 3 and improving the practicality of the heat exchange assembly 10.

[0056] In addition, it can also be designed flexibly according to the situation, for example, the heat exchange tube 3 is used to play a heating role in a low temperature environment.

[0057] In some embodiments of the present application, the bracket 1 further includes a guide structure 12 arranged at the edge of the mounting groove 11, and a side surface of the guide structure 12 facing the mounting groove 11 is formed as a guide slope 123 suitable for guiding the first heat exchange plate 2 into the mounting groove 11.

[0058] For example, as shown in FIG2 , the bracket 1 further includes a guide structure 12, which is disposed at the edge of the mounting groove 11. A guide slope 123 is formed on one side of the guide structure 12 facing the mounting groove 11. The guide slope 123 is configured to be inclined from a direction away from the bracket 1 toward a direction away from the mounting groove 11. Thus, when the first heat exchange plate 2 is installed in the mounting groove 11 and supported on the guide slope 123, the guide slope 123 can guide the first heat exchange plate 2 into the mounting groove 11. This can reduce the difficulty of installing the first heat exchange plate 2, thereby improving the ease of assembly of the heat exchange assembly 10.

[0059] In some embodiments of the present application, the guide structure 12 includes at least one of a first guide structure 121 disposed outside the installation slot 11 and a second guide structure 122 disposed inside the installation slot 11 .

[0060] For example, as shown in Figure 2, the guide structure 12 can be provided to include a first guide structure 121, the first guide structure 121 is installed outside the mounting groove 11, and the first guide structure 121 is used to guide the first heat exchange plate 2 into the mounting groove 11; or, the guide structure 12 can be provided to include a second guide structure 122, the second guide structure 122 is installed in the mounting groove 11, and the second guide structure 122 is used to guide the first heat exchange plate 2 extending into the mounting groove 11; or, the guide structure 12 can be provided to include a first guide structure 121 and a second guide structure 122, the first guide structure 121 is installed outside the mounting groove 11, the first guide structure 121 is used to guide the first heat exchange plate 2 into the mounting groove 11, the second guide structure 122 is installed in the mounting groove 11, and the second guide structure 122 is used to guide the first heat exchange plate 2 extending into the mounting groove 11.

[0061] The above arrangement can satisfy different working conditions, and when the bracket 1 is provided with both the first guide structure 121 and the second guide structure 122 , the installation smoothness of the first heat exchange plate 2 can be greatly improved.

[0062] In some embodiments of the present application, the guide structure 12 includes a plurality of first guide structures 121 and a plurality of second guide structures 122, the plurality of first guide structures 121 are distributed on both sides of the mounting groove 11 in the first direction F1, and the plurality of second guide structures 122 are distributed on both sides of the mounting groove 11 in the second direction F2, one of the first direction F1 and the second direction F2 is the length direction of the mounting groove 11, and the other is the width direction of the mounting groove 11.

[0063] For example, as shown in Figure 2, one of the first direction F1 and the second direction F2 is the length direction of the mounting groove 11, and the other is the width direction of the mounting groove 11. For example, the first direction F1 can be set as the width direction of the mounting groove 11, and the second direction F2 can be set as the length direction of the mounting groove 11.

[0064] Among them, the guide structure 12 includes multiple first guide structures 121 and multiple second guide structures 122. The multiple first guide structures 121 are divided into two groups. The two groups of first guide structures 121 are distributed on both sides of the installation groove 11 in the first direction F1. Each group has multiple first guide structures 121, and the multiple first guide structures 121 in each group are arranged at intervals along the second direction F2; the multiple second guide structures 122 are divided into two groups. The two groups of second guide structures 122 are distributed on both sides of the installation groove 11 in the second direction F2. Each group has multiple second guide structures 122, and the multiple second guide structures 122 in each group are arranged at intervals along the first direction F1.

[0065] Through the above arrangement, the first guide structure 121 and the second guide structure 122 can jointly guide the first heat exchange plate 2 from different directions, which is beneficial to improving the installation accuracy of the first heat exchange plate 2.

[0066] In some embodiments of the present application, the heat exchange tube 3 includes a plurality of straight pipe sections 31 arranged in parallel, and a curved pipe section 32 connecting the plurality of straight pipe sections 31. The first pipe groove 21 is a plurality of parallel arranged straight pipe sections 31, and the plurality of straight pipe sections 31 are respectively embedded in the first pipe groove 21 in a one-to-one correspondence.

[0067] For example, as shown in FIG3 , the heat exchange tube 3 includes a plurality of straight tube sections 31 and curved tube sections 32. The plurality of straight tube sections 31 are arranged in parallel at intervals. There can be one or more curved tube sections 32. The curved tube sections 32 are used to connect the plurality of straight tube sections 31 so that the cooling energy can flow through the plurality of straight tube sections 31. For example, there can be two straight tube sections 31, which are arranged in parallel at intervals, and the same end of the two straight tube sections 31 is connected by the curved tube section 32; or, there can be three straight tube sections 31, which are arranged in parallel at intervals, and the curved tube section 32 has three joints, which are respectively connected to the three straight tube sections 31; or, there can be three straight tube sections 31, which are arranged in parallel at intervals, and two curved tube sections 32, one curved tube section 32 is used to connect one end of the straight tube section 31 in the middle to the straight tube section 31 on one side, and the other curved tube section 32 is used to connect the other end of the straight tube section 31 in the middle to the straight tube section 31 on the other side.

[0068] At the same time, as shown in Figures 2 and 3, a plurality of first pipe grooves 21 can be provided on the first heat exchange plate 2. The plurality of first pipe grooves 21 are arranged in parallel and spaced apart, and a plurality of straight pipe sections 31 are respectively embedded in the first pipe grooves 21 in a one-to-one correspondence. The heat exchange tubes 3 can collectively transfer cooling energy to the first heat exchange plate 2 via the plurality of straight pipe sections 31, so that the first heat exchange plate 2 can dissipate cooling energy outward more quickly. This helps improve the cooling efficiency of the heat exchange tubes 3 and enhances the practicality of the heat exchange assembly 10.

[0069] In some embodiments of the present application, two straight pipe sections 31 are connected through a curved pipe section 32 to form a heat exchange branch 33 , and the heat exchange tube 3 includes a plurality of heat exchange branches 33 arranged in series or in parallel.

[0070] For example, as shown in Figures 4 and 5, the same end of two straight pipe sections 31 can be connected to form a heat exchange branch 33 through a curved pipe section 32. The heat exchange branch 33 is provided in multiple forms, and the multiple heat exchange branches 33 are arranged in parallel or in series. For example, as shown in Figure 4, the heat exchange tube 3 can be provided with two heat exchange branches 33, and the two heat exchange branches 33 are arranged in parallel, so that the refrigerant can be diverted to the two heat exchange branches 33 to transfer cold energy to the outside through the two heat exchange branches 33; or, as shown in Figure 5, the heat exchange tube 3 can be provided with two heat exchange branches 33, and the two heat exchange branches 33 are arranged in series, so that the refrigerant can flow through the two heat exchange branches 33 in sequence to transfer cold energy to the outside through the two heat exchange branches 33.

[0071] It can be understood that when multiple heat exchange branches 33 are arranged in parallel, the heat exchange uniformity of the heat exchange tube 3 can be improved, and when multiple heat exchange branches 33 are arranged in series, the layout difficulty of the heat exchange tube 3 can be reduced, thereby improving the practicality of the heat exchange component 10.

[0072] In some embodiments of the present application, the two ends of the bracket 1 in the length direction of the straight pipe section 31 are respectively the first end 1a and the second end 2a, the curved pipe section 32 is arranged on the side of the straight pipe section 31 close to the first end 1a, and the curved pipe sections 32 of the multiple heat exchange branches 33 are arranged in a concentric arc shape, the heat exchange tube 3 also includes a connecting pipe section 34, the connecting pipe section 34 is arranged on the side of the straight pipe section 31 close to the second end 2a, and the multiple heat exchange branches 33 are connected through the connecting pipe section 34 so that the multiple heat exchange branches 33 are connected in series or in parallel.

[0073] For example, as shown in FIG2 , the two ends of the bracket 1 along the length of the straight pipe section 31 can be respectively configured as a first end 1a and a second end 2a. As shown in FIG4-5 , the two straight pipe sections 31 of each heat exchange branch 33 can be symmetrically arranged relative to the central axis S, and the curved pipe section 32 is provided on the side of the straight pipe section 31 near the first end 1a. The curved pipe sections 32 of multiple heat exchange branches 33 are arranged in a concentric arc shape and are used to connect to the two straight pipe sections 31 of the same heat exchange branch 33.

[0074] As shown in Figures 4 and 5, the heat exchange tube 3 also includes a connecting pipe section 34, which is disposed on a side of the straight tube section 31 near the second end 2a. Multiple heat exchange branches 33 are connected via the connecting pipe section 34, allowing the multiple heat exchange branches 33 to be connected in series or in parallel. Specifically, as shown in Figure 5, the connecting pipe section 34 can be constructed in a U-shape, connecting the ends of two adjacent heat exchange branches 33 to achieve a series connection of the multiple heat exchange branches 33. Alternatively, as shown in Figure 4, the ends of multiple heat exchange branches 33 can be connected to the same joint via the connecting pipe section 34 to achieve a parallel connection of the multiple heat exchange branches 33.

[0075] Through the above arrangement, the layout of the heat exchange branches 33 can be simplified, and a uniform spacing can be maintained between two adjacent heat exchange branches 33, which is beneficial to improving the cooling uniformity of the heat exchange component 10.

[0076] In some embodiments of the present application, the bracket 1 has multiple locking parts 13, which are respectively arranged on both sides of the first heat exchange plate 2 in the length direction of the straight pipe section 31, and the heat exchange tube 3 is limitedly matched with the locking parts 13.

[0077] For example, as shown in FIG2 , the bracket 1 has a plurality of retaining portions 13 , which are divided into two groups. The two groups of retaining portions 13 are respectively provided on both sides of the first heat exchange plate 2 in the longitudinal direction of the straight pipe section 31. Each group is provided with a plurality of retaining portions 13 , and the retaining portions 13 of each group correspond one-to-one with the plurality of straight pipe sections 31. The retaining portions 13 include two buckles 131 , which are respectively provided on both sides of the straight pipe section 31 to define a retaining space. The straight pipe section 31 is adapted to be retained in the retaining space to be fixed to the bracket 1 .

[0078] Through the above arrangement, the locking portion 13 can fix the straight pipe section 31 from both ends of the straight pipe section 31 along the length direction, thereby improving the installation stability of the straight pipe section 31.

[0079] In some embodiments of the present application, the heat exchange assembly 10 of the electrical control box of the embodiment of the present application further includes: a second heat exchange plate 4, the second heat exchange plate 4 is arranged on the side of the first heat exchange plate 2 away from the bracket 1, and a second pipe groove is provided on the side of the second heat exchange plate 4 facing the first heat exchange plate 2, the first pipe groove 21 corresponds to the second pipe groove and forms an accommodating space, and the heat exchange tube 3 is also embedded in the second pipe groove to pass through the accommodating space.

[0080] For example, referring to Figures 2-7 , the heat exchange assembly 10 further includes a second heat exchange plate 4, which is matched with the first heat exchange plate 2 and disposed on a side of the first heat exchange plate 2 away from the bracket 1. A second pipe groove is defined on the side of the second heat exchange plate 4 facing the first heat exchange plate 2. The second pipe groove is disposed opposite the first pipe groove 21 and is adapted to form a receiving space. The heat exchange tube 3 is matched with the receiving space and can be inserted into the receiving space. A portion of the heat exchange tube 3 is embedded in the first pipe groove 21, and another portion is embedded in the second pipe groove, thereby ensuring stable installation of the heat exchange tube 3.

[0081] Through the above arrangement, the cooling capacity of the heat exchange tube 3 can be diffused outward through the first heat exchange plate 2 and the second heat exchange plate 4 respectively, which is beneficial to improving the cooling efficiency of the heat exchange tube 3 and improving the practicality of the heat exchange component 10.

[0082] In some embodiments of the present application, the second heat exchange plate 4 can be secured to the bracket 1 via fasteners that penetrate the second heat exchange plate 4 and the first heat exchange plate 2. Specifically, a first avoidance hole 41 can be provided on the first heat exchange plate 2, and a corresponding second avoidance hole can be provided on the second heat exchange plate 4. The first avoidance hole 41 and the second avoidance hole together define a avoidance channel. The fastener can pass through the avoidance channel from the side of the second heat exchange plate 4 away from the bracket 1, sequentially penetrate the second heat exchange plate 4 and the first heat exchange plate 2, and connect to the bracket 1, thereby securing the second heat exchange plate 4 to the bracket 1. This facilitates installation of the second heat exchange plate 4 and improves installation stability of the second heat exchange plate 4.

[0085] According to the electric control box 100 of the embodiment of the present application, the circuit board 20 can be efficiently cooled by the heat exchange tube 3, which helps to reduce the temperature of the circuit board 20 and improve the working reliability of the electric control box 100.

The top cover can be secured to the bracket 1 via fasteners that penetrate the top cover and the first heat exchange plate 2. This arrangement improves the installation stability of the heat exchange assembly 10.

[0091] In an actual setting, when the electric control box 100 has an X2 structure, the electric control box 100 can be provided with a partition 30, and the circuit board 20 can be installed on the partition 30 or on the top cover; and when the electric control box 100 has an X4 structure, the partition 30 is not required, and the circuit board 20 can be directly installed on the top cover.

[0092] In some embodiments of the present application, the electrical control box 100 includes a box body 40, and the heat exchange component 10 is arranged in the box body 40; the first side wall 401 of the box body 40 is provided with a first air vent and a first guide plate 402, and the first guide plate 402 is arranged corresponding to the first air vent, and the upper end of the first guide plate 402 is connected to the upper edge of the first air vent, and the lower end extends toward the interior of the box body 40 and is spaced from the lower edge of the first air vent; the bottom wall 403 of the box body 40 is provided with a second air vent and a second guide plate 404, and the second guide plate 404 is arranged corresponding to the second air vent, and the lower end of the second guide plate 404 is connected to a side edge of the second air vent away from the first side wall 401, and the upper end extends toward the interior of the box body 40 toward the first side wall 401 to be spaced from the opposite side edge of the second air vent.

[0093] For example, as shown in Figure 8 , the electrical control box 100 includes a box body 40, which is provided with an installation space, and the heat exchange assembly 10 is disposed within the installation space of the box body 40. A first air vent and a first guide plate 402 are provided on a first side wall 401 of the box body 40. The first air vent extends through the first side wall 401 along the thickness direction. The first guide plate 402 is located within the first side wall 401 and is disposed corresponding to the first air vent. The upper end of the first guide plate 402 is configured to connect to the upper edge of the first air vent, and the lower end of the first guide plate 402 is configured to extend toward the interior of the box body 40 to be spaced apart from the lower edge of the first air vent, thereby forming a first air gap.

[0095] Specifically, when the electrical control box 100 begins operation, the circuit board 20 generates heat. Airflow from outside the box body 40 can flow in through the second air vents and, guided by the second guide plate 404, be blown into the installation space from the second air gap. The airflow can then flow along the installation space toward the first sidewall 401 and into the first air gap, where it can be blown out of the electrical control box 100 through the first air vents under the guidance of the first guide plate 402. Of course, airflow can also flow into the installation space from the first air gap and out of the box body 40 from the second air gap, but this will not be discussed further here. This allows for efficient heat dissipation of the circuit board 20, improving the operational stability of the electrical control box 100.
