DETAILED DESCRIPTION

[0025] The embodiments of the present application are described in detail below, and examples of the embodiments 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 only used to explain the present application, and cannot be understood as limiting the present application.

[0026] Reference below Figure 1-Figure 2 The electric control box 100 according to the embodiment of the present application is described.

[0027] The electric control box 100 according to the embodiment of the present application includes: a housing 1 , a mounting bracket 2 and a heat dissipation assembly 3 .

[0028] Reference Figure 1 The housing 1 has a cavity, which can be used to install and arrange a control board (not shown in the figure, such as: electronic components such as a PCB board) and a heat dissipation component 3. The heat dissipation component 3 can be used to dissipate heat from the electronic components to reduce the temperature of the electronic components.

[0029] Further, the mounting bracket 2 is arranged in the housing 1, and the mounting bracket 2 is used to install and fix the heat dissipation component 3 to fix the heat dissipation component 3 in the housing 1. The heat dissipation component 3 can be in contact with the control board for heat exchange to enhance the cooling effect of the heat dissipation component 3 on the control board.

[0030] Reference Figure 1 and Figure 2 The heat dissipation assembly 3 includes a first heat dissipation part 31 and a second heat dissipation part 32. The first heat dissipation part 31 is installed on the mounting bracket 2. The second heat dissipation part 32 is connected to the first heat dissipation part 31. The first heat dissipation part 31 and the second heat dissipation part 32 are arranged in an L shape. The heat exchange tube 33 is used for allowing heat exchange medium (such as refrigerant) to pass through. The heat exchange tube 33 is installed on the second heat dissipation part 32.

[0031] The second heat dissipation part 32 is used to install and fix the heat exchange tube 33, and the heat exchange tube 33 can exchange heat with the second heat dissipation part 32. Since the first heat dissipation part 31 is connected to the second heat dissipation part 32, the first heat dissipation part 31 also has a good heat dissipation effect.

[0032] Reference Figure 1 The first heat dissipation portion 31 is laterally supported on the mounting bracket 2, and a side surface of the first heat dissipation portion 31 facing away from the mounting bracket 2 (i.e. Figure 1 The upper surface of the heat dissipation component 3 in the upper surface of the heat dissipation component 3 can be used to arrange the control board to exchange heat with the control board through the first heat dissipation component 31. The second heat dissipation component 32 is arranged on one side of the first heat dissipation component 31 and is arranged in an L shape with the first heat dissipation component 31. The heat exchange tube 33 can be fixed by the second heat dissipation component 32, so that the heat exchange tube 33 is arranged at the lateral position of the first heat exchange component, reducing the space occupied by the heat dissipation component 3 in the vertical direction, and the heat dissipation area of ​​the heat dissipation component 3 arranged in an L shape is large, which can improve the heat dissipation effect of the electric control box 100.

[0033] It should be noted that in the related art, the number of components in the electric control box 100 is large, resulting in a complex structure of the heat dissipation pipe, thereby increasing the difficulty of installing the electric control box 100. At the same time, the radiator in the electric control box 100 is connected to the heat dissipation pipe, and the structure of the radiator is limited by the heat dissipation pipe, and the heat dissipation area cannot be guaranteed, which affects the heat dissipation effect of the electric control box 100.

[0034] In the present application, the first heat dissipation part 31 in the heat dissipation assembly 3 is fixed by the mounting bracket 2, and the heat exchange tube 33 is fixed to one side of the first heat dissipation part 31 by being located at the second heat dissipation part 32, so that the heat dissipation area of ​​the heat dissipation assembly 3 can be increased while ensuring the heat exchange effect between the heat exchange tube 33 and the second heat dissipation part 32, thereby improving the heat dissipation effect of the electric control box 100. At the same time, the shape and size of the heat exchange tube 33 can be adaptively adjusted to shorten the size of the heat exchange tube 33.

[0035] like Figure 2 As shown, in some embodiments of the present application, the second heat dissipation portion 32 includes: a first sub-heat dissipation portion 321 and a second sub-heat dissipation portion 322, the first sub-heat dissipation portion 321 is connected to the first heat dissipation portion 31, the second sub-heat dissipation portion 322 is arranged on a side of the first sub-heat dissipation portion 321 away from the mounting bracket 2, and the second sub-heat dissipation portion 322 is arranged opposite to the first sub-heat dissipation portion 321, and the heat exchange tube 33 is arranged between the first sub-heat dissipation portion 321 and the second sub-heat dissipation portion 322.

[0036] Reference Figure 1The first sub-heat dissipation part 321 is vertically arranged, the heat exchange tube 33 is arranged between the first sub-heat dissipation part 321 and the second sub-heat dissipation part 322, and the heat exchange tube 33 is located on the side of the first sub-heat dissipation part 321 away from the mounting bracket 2, thereby preventing the heat exchange tube 33 from interfering with the mounting bracket 2 and reducing the difficulty of arranging the heat exchange tube 33.

[0037] Furthermore, by clamping the heat exchange tube 33 between the first sub-heat dissipation part 321 and the second sub-heat dissipation part 322, the contact area between the heat exchange tube 33 and the second heat dissipation part 32 (i.e., the first sub-heat dissipation part 321 and the second sub-heat dissipation part 322) can be ensured, the heat exchange effect between the heat exchange tube 33 and the radiator can be ensured, and the heat exchange tube 33 can be fixed by clamping, thereby reducing the difficulty of assembling the heat exchange tube 33 and the second heat dissipation part 32.

[0038] like Figure 2 As shown, in some embodiments of the present application, the first sub-heat dissipation portion 321 and the first heat dissipation portion 31 are constructed as one body, thereby ensuring the heat exchange effect between the first sub-heat dissipation portion 321 and the first heat dissipation portion 31 and reducing the difficulty of assembling the components in the heat dissipation assembly 3.

[0039] It can be understood that the second heat sink 32 is composed of two parts, namely, the first sub-heat sink 321 and the second sub-heat sink 322, and the first sub-heat sink 321 and the second sub-heat sink 322 are connected and matched to fix the heat exchange tube 33 between the first sub-heat sink 321 and the second sub-heat sink 322. When the first sub-heat sink 321 and the first heat sink 31 are constructed as one body, there is no need to further connect the first sub-heat sink 321 with the first heat sink 31, which reduces the assembly steps of the electric control box 100, reduces the assembly difficulty of the electric control box 100, and improves the assembly efficiency.

[0040] like Figure 2 As shown, in some embodiments of the present application, the first sub-heat dissipation portion 321 is provided with a first installation groove 3211 open to one side of the second sub-heat dissipation portion 322, and the heat exchange tube 33 is provided in the first installation groove 3211, so that the heat exchange tube 33 is installed in the first sub-heat dissipation portion 321.

[0041] Among them, the heat exchange tube 33 can be embedded in the first installation groove 3211, the first installation groove 3211 has a limiting and fixing function on the heat exchange tube 33, and further through the connection and cooperation between the first sub-heat dissipation part 321 and the second sub-heat dissipation part 322, the heat exchange tube 33 can be clamped and arranged between the first sub-heat dissipation part 321 and the second sub-heat dissipation part 322.

[0042] like Figure 2As shown, in some embodiments of the present application, the second sub-heat dissipation portion 322 is provided with a second installation groove 3221 open to one side of the first sub-heat dissipation portion 321, and the heat exchange tube 33 is arranged in the second installation groove 3221, so that the heat exchange tube 33 is installed in the second sub-heat dissipation portion 322.

[0043] Among them, the heat exchange tube 33 can be embedded in the second installation groove 3221, and the second installation groove 3221 has a limiting and fixing function on the heat exchange tube 33, and further through the connection and cooperation between the first sub-heat dissipation part 321 and the second sub-heat dissipation part 322, the heat exchange tube 33 can be clamped and arranged between the first sub-heat dissipation part 321 and the second sub-heat dissipation part 322.

[0044] It should be noted that the second heat dissipation part 32 can be fixed to the heat exchange tube by only providing one mounting groove, that is, only the first mounting groove 3211 is provided on the first sub-heat dissipation part 321, and the heat exchange tube 33 is installed through the first mounting groove 3211, or only the second mounting groove 3221 is provided on the second sub-heat dissipation part 322, and the heat exchange tube 33 is installed through the second mounting groove 3221. The second heat dissipation part 32 can also be matched with two mounting grooves (i.e., the first mounting groove 3211 and the second mounting groove 3221) to fix the heat dissipation tube, that is, the first sub-heat dissipation part 321 is provided with the first mounting groove 3211, and the second sub-heat dissipation part 322 is provided with the second mounting groove 3221, and the first mounting groove 3211 and the second mounting groove 3221 are arranged opposite to each other. When the first sub-heat dissipation part 321 and the second sub-heat dissipation part 322 are buckled and matched, the heat exchange tube 33 is arranged in the installation space defined by the first mounting groove 3211 and the second mounting groove 3221.

[0045] It can be understood that when the heat exchange tube 33 is arranged in the first installation groove 3211, the heat exchange tube 33 can fully contact with the first sub-heat dissipation part 321 to ensure the heat exchange effect between the heat exchange tube 33 and the first sub-heat dissipation part 321; when the heat exchange tube 33 is arranged in the second installation groove 3221, the heat exchange tube 33 can fully contact with the second sub-heat dissipation part 322 to ensure the heat exchange effect between the heat exchange tube 33 and the second sub-heat dissipation part 322.

[0046] Reference Figure 2 The first mounting groove 3211 in the first sub-heat dissipation part 321 can be specifically constructed as two groove structures extending in a straight line and arranged at intervals, and the two groove structures are respectively matched with the first pipe section 331 and the second pipe section 332. Among them, the second mounting groove 3221 in the second sub-heat dissipation part 322 is similar in structure to the first mounting groove 3211, and will not be repeated here. At the same time, the openings of the first mounting groove 3211 and the second mounting groove 3221 are arranged opposite to each other.

[0047] like Figure 1 and Figure 2As shown, in some embodiments of the present application, a support rib 34 is provided at the connection between the first heat dissipation part 31 and the first sub-heat dissipation part 321, and the support rib 34 is connected between the first heat dissipation part 31 and the first sub-heat dissipation part 321 to enhance the connection strength between the first heat dissipation part 31 and the first sub-heat dissipation part 321 and prevent deformation of the connection between the first heat dissipation part 31 and the first sub-heat dissipation part 321.

[0048] Reference Figure 1 The support rib 34 can be constructed as a strip support rib 34, one end of the support rib 34 is connected to the first heat dissipation part 31, and the other end of the support rib 34 is connected to the first sub-heat dissipation part 321, and the support rib 34 is obliquely supported between the first heat dissipation part 31 and the first sub-heat dissipation part 321. A triangular support structure is formed between the support rib 34, the first heat dissipation part 31 and the first sub-heat dissipation part 321, thereby fully improving the structural strength of the connection between the first heat dissipation part 31 and the first sub-heat dissipation part 321 and improving the anti-deformation capability.

[0049] Furthermore, the supporting ribs 34 are structured as a plurality of supporting ribs 34 which are parallel to each other and spaced apart to further enhance the structural strength of the connection between the first heat dissipation portion 31 and the first sub-heat dissipation portion 321 and enhance the anti-deformation capability.

[0050] like Figure 2 As shown, in some embodiments of the present application, the heat exchange tube 33 includes: a first tube segment 331 , a second tube segment 332 and a transition tube segment 333 .

[0051] The first pipe section 331 is used for heat exchange medium to enter, the second pipe section 332 is used for heat exchange medium to discharge, the transition pipe section 333 is connected between the first pipe section 331 and the second pipe section 332, and the heat exchange medium can flow through the first pipe section 331, the transition pipe section 333 and the second pipe section 332 in sequence. Thus, the heat exchange pipe 33 forms a flow channel for the heat exchange medium to flow through.

[0052] Reference Figure 1 The transition pipe section 333 is arranged outside the installation groove, and the installation groove does not need to be adapted to the shape of the transition pipe section 333, which can reduce the difficulty of processing the installation groove. Figure 2 The first pipe section 331 and the second pipe section 332 are both constructed as straight pipe sections. Accordingly, the first installation groove 3211 and the second installation groove 3221 are respectively constructed as groove structures extending in a straight line along the vertical direction.

[0053] like Figure 2 As shown, in some embodiments of the present application, the first pipe segment 331 , the second pipe segment 332 and the transition pipe segment 333 are arranged on the same plane, so that the structure of the heat exchange tube 33 can be simplified and the processing difficulty of the heat exchange tube 33 can be reduced.

[0054] In a further embodiment of the present application, the heat exchange tube 33 is constructed as a U-shaped tube, which has a simple structure and is easy to assemble. Figure 1 The two ports of the U-shaped tube are located on the same side, making it easy to connect the U-shaped tube in series to the refrigerant circulation loop.

[0055] It should be noted that in the related art, the heat exchange tube 33 in the electric control box 100 is connected to the radiator. The shape and arrangement position of the heat exchange tube 33 are affected by the radiator. The heat exchange tube 33 needs to be constructed to be longer in length, and the shape of the heat exchange tube 33 is irregular, which makes it difficult to assemble the heat exchange tube 33.

[0056] In the present application, the heat exchange tube 33 is connected to the second heat dissipation part 32. The first heat dissipation part 31 and the second heat dissipation part 32 are arranged in an L-shape, which is convenient for avoiding the mounting bracket 2. The heat exchange tube 33 arranged in a U-shape is arranged in the second heat dissipation part 32 by an embedded manner. There is no need to bend the heat exchange tube 33, and the length of the heat exchange tube 33 can be shortened.

[0058] Reference Figure 1 The bottom wall 111 of the lower shell 11 is formed with a notch (i.e., the avoidance structure mentioned above), and the heat dissipation assembly 3 (such as: the second heat dissipation portion 32 and the heat exchange tube 33) can extend from the notch, thereby reducing the difficulty of connecting and assembling the heat exchange tube 33 in the refrigerant circulation loop. At the same time, the heat exchange tube 33 is constructed as a U-shaped tube, and the U-shaped tube is arranged vertically to arrange the U-shaped tube at a position suitable for extending from the notch.

[0059] like Figure 1 As shown, in some embodiments of the present application, the side wall 112 of the lower shell 11 is provided with a through hole 113, and the through hole 113 is used to connect the inside of the shell 1 with the outside to improve the heat dissipation effect at the electric control box 100.

[0060] Reference Figure 2 The shell 1 also includes an upper cover 12, which can be snapped together with the lower shell 11 to form an installation space for arranging the mounting bracket 2 and the heat dissipation component 3. The upper cover 12 can play a good shielding role for the mounting bracket 2, the heat dissipation component 3 and components such as the electric control board arranged in the shell 1, thereby reducing the pollution of dust and other pollutants to the components in the shell 1.

[0061] Furthermore, the upper cover 12 and the lower shell 11 can be fixed by a snap-fit ​​connection method, which is simple and easy to operate, can reduce the difficulty of assembling the electric control box 100, and can ensure the connection reliability between the upper cover 12 and the lower shell 11.

[0063] Reference Figure 1 and Figure 2 The mounting seat 21 is arranged horizontally (i.e., the mounting surface of the mounting seat 21 is arranged horizontally) on the lower shell 11, and the support arm 22 can support the mounting seat 21, and a gap is formed between the inner wall of the shell 1 and the mounting seat 21. The gap can be used for the wiring harness to pass through, so as to facilitate the wiring harness arrangement in the electric control box 100, and a gas channel can also be formed at the gap for air to pass through, thereby ensuring the heat dissipation effect of the electric control box 100.

[0064] like Figure 2 As shown, in some embodiments of the present application, a slot 113 is provided on the inner wall of the housing 1 , and a hook 23 is provided on the end of the support arm 22 , and the hook 23 is engaged with the slot 113 .

The card connection method is simple, easy to assemble and has high reliability.

[0066] Furthermore, when the hook 23 is engaged with the slot 113 , the lower end of the support arm 22 can abut against the bottom wall 111 of the housing 1 to play a supporting and limiting role, thereby fixing the mounting bracket 2 to the housing 1 .

[0067] In some embodiments of the present application, there are multiple support arms 22 , so that the mounting base 21 is supported by the multiple support arms 22 , thereby improving the support stability of the support arms 22 on the mounting base 21 .

[0068] Reference Figure 1 Specifically, the mounting seat 21 is provided with four support arms 22 , and the four support arms 22 are arranged to be opposite to each other and spaced apart, so as to fully support the mounting seat 21 .
