Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of vehicle accessories, and more specifically, to a distribution box and a vehicle. Background Art

[0002] When the distribution box is working, the electrical components will emit a lot of heat. The distribution box that is widely used at present has a relatively closed structure, and the air flow inside the box is poor. The heat in the distribution box cannot be discharged in time.

[0055] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0056] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0057] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0058] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0059] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0060] The embodiment of the present application provides a distribution box to solve the technical problem in the prior art that the distribution box cannot directly dissipate heat for the heating element, resulting in poor heat dissipation effect.

[0061] Reference Figure 1-Figure 8 The distribution box comprises: a box body 1, wherein the box body 1 has a first plate 11 and a second plate 12; the second plate 12 has a cooling component 2. A power heating element 3, wherein the power heating element 3 is placed in the box body 1 and fixed on the first plate 11; a heat conductive adhesive layer 4 is provided between the first plate 11 and the power heating element 3.

[0062] In the embodiment of the present application, the distribution box mainly includes a box body 1 and a power heating element 3, and the power heating element 3 is arranged in the box body 1. For example, the box body 1 includes a plurality of plates, and the plurality of plates are enclosed to form the box body 1, so that a receiving cavity is formed in the box body 1, and the power heating element 3 is placed in the receiving cavity.

[0063] The box body 1 includes a plurality of plates, including a first plate 11 and a second plate 12. The power heating element 3 is placed in the box body 1. Specifically, the power heating element 3 is fixed on the first plate 11. For example, the power heating element 3 can be fixed on the first plate 11 by fasteners, and the fasteners can be screws, etc.

[0064] When the power heating element 3 is fixed on the first plate 11, a heat conductive adhesive layer 4 is provided between the power heating element 3 and the first plate 11. That is, the power heating element 3 and the first plate 11 are effectively bonded together through the heat conductive adhesive layer 4.

[0065] On the one hand, during the operation of the power heating element 3, the power heating element 3 generates heat, and the thermal conductive adhesive layer 4 can effectively and directly transfer the heat to the first plate 11, and then transfer the heat to the second plate 12 through the first plate 11, and directly dissipate the heat from the power heating element 3 through the cooling component 2 of the second plate 12. It should be noted that during the operation of the power heating element 3, the power heating element 3 generates heat, and when the thermal conductive adhesive layer 4 transfers the heat to the first plate 11, the first plate 11 can also dissipate the heat generated by the power heating element 3, but only a very small part of the heat of the power heating element can be dissipated through the first plate 11.

[0066] On the other hand, the thermal conductive adhesive layer 4 can fix the power heating element 3 to ensure that the power heating element 3 meets the 6G vibration test (reliability test). For example, when the distribution box is installed on a vehicle, the power heating element 3 is reliably fixed during the bumpy process of the vehicle.

[0067] Therefore, in the embodiment of the present application, a heat-conducting adhesive layer 4 is provided between the first plate 11 of the box body 1 and the power heating element 3, and the cooling component 2 of the second plate 12 can directly cool and dissipate heat to the power heating element 3 through the heat-conducting adhesive layer 4. This method of directly dissipating heat to the power heating element through the cooling component 2 can effectively reduce the heat generated by the power heating element 3 and achieve a good heat dissipation effect on the power heating element 3.

[0068] It should be noted that, in the embodiment of the present application, the power heating element 3 is fixed on the first plate 11, and the second plate 12 has a cooling component 2, that is, the power heating element 3 and the cooling component 2 are arranged on different plates of the box body 1. Specifically, when the power heating element 3 is fixed on the first plate 11, and the first plate 11 also has a cooling component 2, leakage problems are prone to occur. In addition, when a thermally conductive adhesive layer 4 is arranged between the power heating element 3 and the first plate 11, since the first plate 11 has a cooling component 2, the thermally conductive adhesive layer 4 cannot be arranged flatly between the power heating element 3 and the first plate 11, which affects the fixing effect of the thermally conductive adhesive layer 4 on the power heating element 3, and also affects the effect of the thermally conductive adhesive layer 4 on transferring the heat generated by the power heating element 3. Therefore, in the embodiment of the present application, the power heating element 3 and the cooling component 2 are arranged on different plates of the box body 1.

[0069] In one embodiment, referring to Figure 4 The second plate 12 includes a plate body 121, and the cooling component 2 includes a liquid cooling plate 20. A connecting hole is provided on the plate body 121, and the liquid cooling plate 20 is connected to the connecting hole and seals the connecting hole.

[0070] In this embodiment, the second plate 12 includes a plate body 121 , and a connection hole is formed on the plate body 121 . For example, the connection hole can be formed on the plate body 121 by stamping or the like.

[0071] The cooling component 2 includes a liquid cooling plate 20 , and the liquid cooling plate 20 can be connected to the connection hole by a friction stir welding process and seal the connection hole.

[0072] Therefore, in this embodiment, a liquid cooling plate 20 is provided on the plate body 121 so that a cooling component is formed on the second plate, and the power heating element 3 provided on the first plate 11 can be directly cooled by the cooling component.

[0073] In one embodiment, referring to Figure 7 and Figure 8 In the first direction of the cooling component 2 , the cooling component has a first area 241 , a second area 242 and a third area 243 , and the second area 242 is located between the first area 241 and the third area 243 .

[0074] Specifically, in the first direction of the cooling component 2, for example, the first direction may be the width direction of the liquid cooling plate 20, and also the width direction of the distribution box. In the width direction of the liquid cooling plate 20, the cooling component is divided into three areas as a whole, including a first area 241, a second area 242 and a third area 243, and the second area 242 is located between the first area 241 and the third area 243.

[0075] In this embodiment, the cooling component 2 is divided into areas, and the diverter ribs of the cooling component can be designed according to the divided areas, so that the liquid inlet 22, the liquid outlet 23 and the flow channel 21 of the cooling component 2 are also planned according to the divided areas, so that the flow channel design in the cooling component 2 is more reasonable, and the power heating element can be evenly cooled.

[0076] In one embodiment, the cooling component 2 further includes a plurality of diverter ribs, wherein the plurality of diverter ribs include a first diverter rib 281, a second diverter rib 282 and a third diverter rib 283;

[0077] One end of the first diverter rib 281 is located at the connection between the second area 242 and the third area 243 , and the other end of the first diverter rib 281 is located in the first area 241 ;

[0078] In the second direction of the cooling component, the second diverter rib 282 and the third diverter rib 283 are located on both sides of the first diverter rib 281, and part of the second diverter rib 282 and part of the third diverter rib 283 define the boundary of the third area 243 in the second direction, and the first direction is perpendicular to the second direction.

[0079] Specifically, the cooling component 2 further includes a plurality of diverter ribs, which can be formed on the liquid cooling plate 20 or on the plate body 121. For example, the diverter ribs can be formed on the liquid cooling plate 20 and / or the plate body 121 by a molding process such as extrusion.

[0080] The cooling component 2 is provided with three diverter ribs, including a first diverter rib 281, a second diverter rib 282 and a third diverter rib 283. One end of the first diverter rib 281 extends to the connection between the second area 242 and the third area 243, and the other end of the first diverter rib 281 extends into the first area 241. The first diverter rib 281 is mainly used to divert the second area 242 of the cooling component 2, so as to divide the second area 242 into multiple flow channels, which can improve the heat dissipation efficiency of the cooling component 2 to the power heating element 3.

[0081] The second direction of the cooling component 2 and the first direction of the cooling component 2 are two directions perpendicular to each other. For example, the second direction of the cooling component 2 may be the length direction of the liquid cooling plate 20 .

[0082] In the length direction of the liquid cooling plate 20, the second diverter rib 282 and the third diverter rib 283 are respectively located on both sides of the first diverter rib 281. For example, one end of the second diverter rib 282 is located in the third area 243, and the other end of the second diverter rib 282 is located in the second area 242. The second diverter rib 282 is located on the first side of the first diverter rib 281. The second diverter rib 282 can divert the liquid inlet 22 and the second area 242.

[0083] One end of the third diverter rib 283 is located in the third area 243 , and the other end of the third diverter rib 283 is located in the second area 242 . The third diverter rib 283 is located on the second side of the first diverter rib 281 . The third diverter rib 283 can divert the liquid outlet 23 and the second area 242 .

[0084] In addition, the second diverter rib 282 and the third diverter rib 283 are located on both sides of the first diverter rib 281, and part of the second diverter rib 282 and part of the third diverter rib 283 define the boundary of the third area 243 in the second direction, so that the second diverter rib 282 and the third diverter rib 283 play the role of diverting and strengthening the guidance of water flow, so that the water flow arrangement inside the cooling component is more reasonable.

[0085] In one embodiment, the cooling component 2 has a flow channel 21, a liquid inlet 22 and a liquid outlet 23, and the liquid outlet 23 and the liquid inlet 22 are connected through the flow channel 21;

[0086] The plate body 121 , the liquid cooling plate 20 and the flow dividing ribs define the flow channel 21 of the cooling component 2 .

[0087] In this embodiment, the liquid cooling plate 20 has a flow channel 21, a liquid inlet 22 and a liquid outlet 23, and the liquid inlet 22 and the liquid outlet 23 are connected through the flow channel 21. For example, the flow channel 21 contains cooling liquid, which enters from the liquid inlet 22 and can flow out from the liquid outlet 23 after passing through the flow channel 21.

[0088] The plate body, the liquid cooling plate 20 and the flow dividing ribs define the flow channel of the cooling component, making the flow channel arrangement more reasonable. After the flow channel 21 is filled with coolant, the coolant flows from the liquid inlet 22 to the liquid outlet 23, and the cooling component 2 performs good heat conduction and heat dissipation on the power heating element 3.

[0089] In one embodiment, a spoiler is disposed in the flow channel 21 .

[0090] In this embodiment, a spoiler is provided in the flow channel 21 , for example, a plurality of spoilers are provided in the flow channel 21 , so as to disturb the water flow in the flow channel 21 and slow down the flow velocity, thereby increasing the time for concentrated heat dissipation of the power heating element 3 .

[0091] In one embodiment, the spoiler is disposed on the plate body and / or the liquid cooling plate 20 .

[0092] In this embodiment, for example, a spoiler may be formed on the plate body 121 , or a spoiler may be formed on the liquid cooling plate 20 , or a spoiler may be formed on both the plate body 121 and the liquid cooling plate 20 .

[0093] In one embodiment, referring to Figure 7 and Figure 8 , the spoiler includes a first spoiler 25 and a second spoiler 26;

[0094] The first spoiler 25 is disposed in the flow channel 21, and the first spoiler 25 is disposed at a position corresponding to the first area 241 and the third area 243;

[0095] The second spoiler 26 is disposed in the flow channel 21 , and the second spoiler 26 is disposed at a position corresponding to the second area 242 .

[0096] In this embodiment, the cooling component 2 is divided into regions, and the cooling component flow channel 21 is arranged to achieve heat dissipation for the power heating element 3.

[0097] Specifically, a plurality of first spoiler columns are arranged in the flow channel 21 located in the first area 241 and the third area 243 to break up the water flow and prevent the water flow from being too fast and affecting the heat dissipation; and a plurality of second spoiler columns are arranged in the flow channel 21 located in the second area 242 to realize flow diversion, so as to achieve the purpose of heat dissipation and temperature reduction in the heat concentrated area of ​​the power heating element 3.

[0098] Therefore, in this embodiment, a plurality of first spoilers 25 are arranged in the flow channel 21 of the first area 241 and the third area 243, and a plurality of second spoilers 26 are arranged in the flow channel 21 of the second area 242. The main purpose is to prevent the coolant in the flow channel 21 from flowing unimpeded. Too smooth water flow will affect the heat dissipation of the heat-generating power components.

[0099] Optionally, the area of ​​the second region 242 is larger than the area of ​​the first region 241, and the area of ​​the second region 242 is larger than the area of ​​the third region 243. Or the area of ​​the second region 242 is even larger than the sum of the area of ​​the first region 241 and the area of ​​the third region 243. In this embodiment, the area of ​​the second region 242 is limited to achieve the purpose of heat dissipation and temperature reduction of the heat concentrated area of ​​the power heating element 3.

[0100] In one embodiment, referring to Figure 7 , in the second direction of the cooling component, the liquid inlet 22 is located on one side of the second diverter rib 282 and is arranged away from the third area 243, and the liquid outlet 23 is located on one side of the third diverter rib 283 and is arranged away from the third area 243;

[0101] The liquid inlet 22 is directly connected to the flow channel 21 of the first area 241 , and the liquid outlet 23 is directly connected to the flow channel 21 of the second area 242 .

[0102] In this embodiment, the locations of the liquid inlet 22 and the liquid outlet 23 are limited to achieve a better flow diversion effect.

[0103] The liquid inlet 22 is located at one side edge of the cooling component 2, for example, at one side of the second diverter rib 282 of the liquid inlet 22 and away from the third area 243, so that the coolant flowing in from the liquid inlet 22 can flow directly to the first area 241 and flow over the first diverter rib 281 to the second area 242.

[0104] The liquid outlet 23 is located at the other side edge of the cooling component 2. For example, the liquid outlet 23 is located on one side of the third diverter rib 283 and is arranged away from the third area 243. The liquid outlet 23 is directly connected to the flow channel of the second area 242. In this way, after the coolant flows to the third area 243, it continues to flow to the second area 242 and the first area 241 under the guidance of the third diverter rib 283, and then bypasses the third diverter rib 283, flows to the second area 242, and finally flows to the liquid outlet 23.

[0105] Specifically, the coolant enters the flow channel 21 from the liquid inlet 22. Under the limitation of the structure of the liquid inlet 22 and the structure of the first diverter rib 281, the coolant first passes through the flow channel 21 located in the first area 241, then flows downward along the flow channel 21 of the first area 241 and bypasses the first diverter rib 281 to flow to the flow channel 21 of the second area 242; then continues to flow downward along the flow channel 21 of the second area 242 to flow to the flow channel 21 of the third area 243; then, under the limitation of the bend structure of the third area 243 and the structure of the third diverter rib 283, flows upward along the flow channel 21 of the third area 243 to the flow channel 21 of the second area 242; continues to flow upward along the flow channel 21 of the second area 242 to flow to the flow channel 21 of the first area 241; flows downward along the bend structure of the first area 241 to flow to the flow channel 21 of the second area 242, and finally flows along the flow channel 21 of the second area 242 to the liquid outlet 23.

[0106] Therefore, in this embodiment, the coolant passes through the flow channel 21 of the first area 241 for many times, and passes through the flow channel 21 of the second area 242 for many times, and passes through the flow channel 21 of the third area 243 for many times, and the power heating element 3 is subjected to heat dissipation treatment. The coolant first passes through the flow channel 21 located in the first area 241, and the coolant is dispersed by the first spoiler 25 so that the coolant can be evenly distributed. The coolant will flow to the flow channel 21 of the second area 242 after passing through the flow channel 21 of the first area 241, and the flow channel 21 of the third area 243 will also flow to the flow channel 21 of the second area 242. Specifically, the heat-concentrating components of the power heating element 3 are cooled and cooled by the second spoiler 26 arranged in the flow channel 21 of the second area 242. In addition, the second spoiler 26 can disperse the water flow again while allowing the coolant water flow to flow normally, thereby reducing the vortex problem formed by the first spoiler 25.

[0107] In one embodiment, referring to Figure 8 The plurality of first spoilers 25 are arranged in an array in the first area 241 , and the first spoilers 25 in two adjacent rows are staggered.

[0108] In this embodiment, the arrangement of the plurality of first spoilers 25 located in the first area 241 is limited, so as to better achieve the effect of breaking up the water flow.

[0109] Specifically, a plurality of first spoilers 25 are arranged in an array, and the first row of first spoilers 25 and the second row of first spoilers 25 are staggered, and the second row of first spoilers 25 and the third row of first spoilers 25 are staggered again, and so on. This arrangement can better achieve the effect of breaking up the water flow. Figure 8 , as shown by arrow a, the first row of first spoilers 25 and the second row of first spoilers 25 are staggered, and the second row of first spoilers 25 and the third row of first spoilers 25 are staggered again.

[0110] In one embodiment, referring to Figure 8 The plurality of first spoilers 25 are arranged in the third area 243 in a trapezoidal structure, and the first spoilers 25 in two adjacent rows are staggered.

[0111] In this embodiment, the arrangement of the plurality of first spoilers 25 located in the third area 243 is limited, so as to achieve a better effect of breaking up the water flow. Figure 8 , arrow b indicates a row, the first row of first spoilers 25 and the second row of first spoilers 25 are staggered, and so on. This arrangement can better achieve the effect of breaking up the water flow.

[0112] In this embodiment, in combination with the shape of the third area 243, a plurality of first spoilers 25 are arranged in a trapezoidal structure in the third area 243. Specifically, the third area 243 is a semicircular structure, and a plurality of first spoilers 25 are arranged in the third area 243 in a semicircular structure.

[0113] In one embodiment, referring to Figure 7 The plurality of second spoilers 26 are arranged in an array in the second area 242 , and the second spoilers 26 in two adjacent rows are staggered.

[0114] In this embodiment, the arrangement of the plurality of second spoiler columns located in the second area 242 is limited, so as to better achieve the effect of guiding the water flow and further breaking up the water flow. Figure 7 , arrow a shows a row, the first row of second spoilers 26 and the second row of second spoilers 26 are staggered, the second row of second spoilers 26 and the third row of second spoilers 26 are also staggered, and so on. This arrangement method better achieves the diversion effect and further dispersion effect on the water flow.

[0115] In one embodiment, referring to Figure 8 , the cross section of the first spoiler 25 is circular.

[0116] In this embodiment, the shape of the cross section of the first spoiler 25 is limited, so as to achieve the effect of breaking up the water flow.

[0117] Specifically, the cross section of the first spoiler 25 is circular, for example, the first spoiler 25 is a cylindrical structure. The cylindrical spoilers arranged in an array can achieve the effect of breaking up the water flow.

[0118] In a specific embodiment, the cross section of the first spoiler 25 is circular, and the diameter of the circle is in the range of 3 mm to 5 mm. Optionally, the diameter of the circle is in the range of 4 mm.

[0119] In one embodiment, referring to Figure 7 , the cross section of the second spoiler 26 is rhombus-shaped.

[0120] In this embodiment, the shape of the cross section of the second spoiler 26 is limited to achieve the effect of guiding the water flow and further breaking up the water flow. Optionally, the diagonal size of the long side of the rhombus is in the range of 6mm to 8mm, and the diagonal size of the short side of the rhombus is in the range of 3mm to 5mm.

[0121] In one embodiment, the third region 243 has a curved structure, and along the curved structure, the edge of the flow channel 21 of the third region 243 forms a third spoiler 27 with a wave structure.

[0122] In this embodiment, the third area 243 has a curved structure, for example, the third area 243 is semicircular, and the edge of the semicircular is a curved structure. Wherein along the shape of the curved structure, the edge of the flow channel 21 of the third area 243 forms a third spoiler 27, and the structure of the third spoiler 27 is a wave structure. Wherein the wave structure can be a sawtooth wave, or the wave structure is a sinusoidal wave. For example, the wave structure is a sinusoidal wave, which can be regarded as having multiple convex structures and concave structures alternately connected, the diameter size of the convex structure is 3.5mm~4.5mm, the height size of the convex structure is 5.5mm~6.5mm, and there is a gap between the convex structure and the box body 1, and the gap size is 0.1mm~0.5mm.

[0123] The third spoiler 27 is arranged at the edge of the flow channel 21 in the third area 243, which can effectively prevent the water flow from forming eddies there, and prevent the water flow from spinning in place and affecting the heat dissipation effect. In addition, the third spoiler 27 with a wave structure can generate resistance to the water flow at the edge of the device, forcing the local water flow to be carried away and flow along the third spoiler 27, which can play a good role in heat conduction and heat dissipation.

[0124] In one embodiment, referring to Figure 6 The thickness of the thermal conductive adhesive layer 4 is 2.5 mm to 3 mm.

[0125] In this embodiment, the thickness of the thermal conductive adhesive layer 4 is limited to ensure the thermal conductive adhesive layer 4 has a transfer effect on the heat generated by the power heating element 3 .

[0126] Specifically, when the thickness of the thermal conductive adhesive layer 4 is less than 2.5 mm, the fixing effect of the thermal conductive adhesive layer 4 on the power heating element 3 is poor, and the power heating element 3 cannot meet the 6G vibration test. When the thickness of the thermal conductive adhesive layer 4 is greater than 3 mm, the thickness of the thermal conductive adhesive layer 4 is relatively thick, and the heat conduction efficiency of the thermal conductive adhesive layer 4 becomes low, which affects the heat transfer of the thermal conductive adhesive layer 4 to the power heating element 3.

[0127] In one embodiment, referring to Figure 5 There is a gap between the power heating element 3 and the cooling component 2, and the gap size is 2mm-3mm.

[0128] In this embodiment, the power heating element 3 is fixed on the first plate 11, and the second plate 12 has a cooling component 2, that is, the plate surface on which the cooling component 2 is set and the plate surface on which the power heating element 3 is fixed, belong to different plate surfaces of the box body 1 of the distribution box. When the power heating element 3 is fixed on the first plate 11, a gap is left between the power heating element 3 and the cooling component 2, which can ensure that the power heating element 3 has sufficient electrical performance and will not have leakage problems.

[0129] In one embodiment, the power heating element 3 is a pulse heating inductor.

[0130] In this embodiment, the power heating element 3 is defined as a pulse heating inductor, which includes an inductor coil 31, an inductor core 32, an inductor copper bus 33 and an inductor temperature sensing wire harness 34, wherein the inductor coil 31 is wound around the inductor core 32, the inductor coil 31 and the inductor copper bus 33 are connected together, and the inductor coil 31 and the inductor temperature sensing wire harness 34 are connected together to form the pulse heating inductor structure.

[0131] The inductive temperature sensing harness 34 is similar to a temperature sensor. The inductive temperature sensing harness 34 is connected to the inductive coil 31 . The inductive temperature sensing harness 34 can sense the temperature of the pulse heating inductor in real time. When the temperature is too high, an alarm can be issued.

[0132] The inductor copper busbar 33 serves as an electrical connection between the pulse heating inductor and the connecting copper busbar.

[0133] In addition, the pulse heating inductor has a fast heat dissipation speed and can be applied to a higher power distribution box circuit. It should be noted that the power heating element 3 includes but is not limited to a pulse heating inductor, and the power heating element 3 can also be other heating power modules in the distribution box.

[0134] In one embodiment, referring to Figure 5 and Figure 6 , the distribution box also includes a first connecting copper bar 51, a second connecting copper bar 52, a first high-voltage connector 53 and a second high-voltage connector 54;

[0135] The first high-voltage connector 53 and the second high-voltage connector 54 are arranged on the box body 1;

[0136] One end of the first connecting copper bar 51 is connected to the first high-voltage connector 53, and the other end of the first connecting copper bar 51 is connected to the pulse heating inductor;

[0137] One end of the second connecting copper bar 52 is connected to the second high-voltage connector 54 , and the other end of the second connecting copper bar 52 is connected to the pulse heating inductor.

[0138] In this embodiment, the distribution box also includes a first connecting copper bus 51, a second connecting copper bus 52, a first high-voltage connector 53 and a second high-voltage connector 54. For example, the first high-voltage connector 53 can be a positive high-voltage connector, and the second high-voltage connector 54 can be a negative high-voltage connector.

[0139] For example, current flows into the positive high-voltage connector, flows to the pulse heating inductor through the first connecting copper bar 51, then flows through the second connecting copper bar 52, and finally flows out through the negative high-voltage connector. When the circuit is working, the pulse heating inductor will generate heat due to the back-and-forth turbulence of the pulse signal. In order to ensure that it can withstand repeated turbulence, the pulse heating inductor needs to dissipate heat in time, which requires the cooling component 2 on the second plate 12 to quickly take away the heat generated by the pulse heating inductor, and the thermal conductive adhesive layer 4 located between the pulse heating inductor and the first plate 11 can effectively transfer the heat of the pulse heating inductor to the cooling component 2 to ensure the heat dissipation requirements of the distribution box. When the distribution box is used in a vehicle, it can meet the needs of the entire vehicle.

[0140] Optionally, the distribution box further includes a low-voltage connector 55, which can play a role in signal transmission and can transmit the signal inside the distribution box to the outside.

[0141] In one embodiment, referring to Figure 4-Figure 6 The first plate 11 is the side plate of the box body 1, and the second plate 12 is the bottom plate of the box body 1; when the power heating element 3 is fixed to the side plate, the power heating element 3 is opposite to the cooling component 2.

[0142] In this embodiment, the first plate 11 is defined as the side plate of the box body 1, the second plate 12 is defined as the bottom plate of the box body 1, and the power heating element 3 is fixed on the side plate, and the lower end of the power heating element 3 is opposite to the second plate 12. Specifically, the lower end of the power heating element 3 is opposite to the cooling component 2, and there is a gap between the lower end of the power heating element 3 and the cooling component 2, which can ensure that the power heating element 3 has sufficient electrical performance and will not have leakage problems.
