[0027] It should also be noted that, Figure 6 The x-direction is the extension direction of the shell 17, the arrow direction of the z-direction points to the upper side, the opposite direction of the arrow of the z-direction is the lower side, the upper side corresponds to the top surface of the shell 17, the lower side corresponds to the bottom surface of the shell 17, and the surface between the top surface and the bottom surface is the side surface.
[0028] In combination with Figures 1 to 5The application provides an electric control box 10, which comprises a box body 11, the box body 11 comprising a base 111, a side wall 113 and a top plate 112, the side wall 113 being arranged on the base 111, and the top plate 112 being arranged on the side wall 113, so that the side wall 113, the top plate 112 and the base 111 jointly enclose a containing cavity 116, and the electric control box 10 further comprises a power module 12, a control module 13 and a capacitor box 14, which are arranged side by side in the containing cavity 116. The electric control box 10 is used for controlling the operation of a cold machine in a vehicle. In the prior art, the capacitor box 14 is usually arranged separately outside the box body 11, at this time, the box body 11 and the capacitor box 14 are arranged separately, thus occupying a large space in the vehicle. According to the application, the capacitor box 14, the power module 12 and the control module 13 are integrated in the box body 11, so that the overall volume of the electric control box 10 and the occupied space in the vehicle can be reduced, and meanwhile, the installation of the electric control box 10 on the vehicle is facilitated. In addition, the power module 12, the control module 13 and the capacitor box 14 are arranged side by side, so that the height of the electric control box 10 can be reduced, and thus the volume of the electric control box 10 is further reduced. Meanwhile, the reduction of the volume of the box body 11 can save material cost.
[0029] In an embodiment, referring to Figure 2 , Figure 3 , Figure 4 , the control module 13 comprises a contactor 131, and the contactor 131 is arranged side by side with the power module 12 on the base 111. By arranging the contactor 131 and the power module 12 side by side, the overall height of the box body 11 can be reduced, and thus the volume of the electric control box 10 and the occupied space in the vehicle can be further reduced.
[0030] In an embodiment, continuing to refer to Figure 2 , Figure 3 , Figure 4 , the control module 13 further comprises a relay 132, and the relay 132 is arranged on the side wall 113. The top plate 112 of the relay 132 is provided with heat-conducting silica gel 16, and the heat-conducting silica gel 16 is arranged in contact with the top plate 112. Since the electrical components in the electric control box 10 need to be cooled, and the relay 132 is also a main heat-generating component, the relay 132 needs to be cooled separately. At this time, the heat-conducting silica gel 16 is arranged on the top surface of the relay 132, the heat of the relay 132 is transferred to the heat-conducting silica gel 16, and the heat-conducting silica gel 16 further transfers the heat to the top plate 112 through contact with the top plate 112, and then the heat is dissipated from the top plate 112 to the outside of the box body 11. Therefore, the heat-conducting silica gel 16 can effectively cool the relay 132.
[0031] In addition, in the prior art, the relay 132 is usually arranged in a stacked manner with the power module 12, at this time, the overall height of the box body 11 is increased, and thus the volume of the electric control box 10 is increased. According to the application, the relay 132 is arranged on the side wall 113, and referring toFigure 4 The relay 132 is located in the accommodating cavity 116 and between the power module 12 and the side wall 113. Compared with stacking the relay 132 on the power module 12, arranging the relay 132 on the side wall 113 does not increase the overall height of the box body 11, and also reduces the volume of the electric control box 10 and the occupied space in the vehicle.
[0032] In an embodiment, referring to Figures 2 to 5 The base 111 is provided with a mounting hole 1111, the capacitor box 14 is fixed to the mounting hole 1111, and part of the capacitor box 14 is located outside the accommodating cavity 116. Since the capacitor box 14 has a high height, extending part of the capacitor box 14 outside the base 111 and into the accommodating cavity 116 also effectively reduces the overall height of the box body 11 and the accommodating cavity 116, thereby effectively reducing the volume of the electric control box 10. In addition, since the capacitor box 14 in the prior art needs to be separately arranged and waterproofed, the cost is increased. The present application directly arranges part of the capacitor box 14 in the accommodating cavity 116. Since the part arranged in the accommodating cavity 116 needs to be electrically connected to other components, it needs to be waterproofed, while the part outside the accommodating cavity 116 does not need to be electrically connected to other components and thus does not need to be waterproofed. Since the accommodating cavity 116 is a sealed cavity, the waterproofing effect of the electrical devices in the accommodating cavity 116 can be achieved, so the capacitor box 14 does not need to be separately waterproofed, thereby saving costs.
[0033] In an embodiment, referring to Figure 5 The base 111 is provided with a support 114 extending away from the side wall 113, the support 114 is provided with a stopper 115 at an end away from the base 111, and an end of the capacitor box 14 located outside the accommodating cavity 116 abuts against the stopper 115. The support 114 is used to support the base 111, and the stopper 115 is used to stop the capacitor box 14, avoiding the capacitor box 14 from being disconnected from the base 111 due to unstable connection. In addition, since the stopper 115 only needs to stop the capacitor box 14, the size of the stopper 115 is matched with the capacitor box 14, so that part of the capacitor box 14 is arranged outside the accommodating cavity 116, and the stopper 115 and the support 114 cooperate to stop the capacitor box 14, thereby saving the material used to manufacture the stopper 115 and saving costs.
[0034] In an embodiment, continuing to refer to Figure 5The electric control box 10 further comprises a radiator 15 arranged on the base 111 and outside the accommodating cavity 116. The radiator 15 is mainly used for dissipating heat of the electrical devices in the accommodating cavity 116, and the power module 12 is the main heat generating device, so the radiator 15 is mainly used for dissipating heat of the power module 12. The radiator 15 is arranged on the base 111 and outside the accommodating cavity 116, so that the heat generated in the accommodating cavity 116 can be taken away.
[0035] In an embodiment, with continued reference to Figure 5 The side of the radiator 15 away from the base 111 is provided with a fan 151 and a plurality of heat dissipation fins 152. The fan 151 is arranged between the plurality of heat dissipation fins 152, and an air duct 153 is formed between adjacent heat dissipation fins 152, so that the hot air sucked by the fan 151 can be discharged in a direction away from the fan 151 after heat exchange with the power module 12. Since the radiator 15 is mainly used for dissipating heat of the power module 12 in the accommodating cavity 116, the fan 151 sucks external air for heat exchange with the power module 12, and the hot air after heat exchange continues to flow in a direction away from the fan 151 along the air duct 153 between adjacent fins, thereby taking away the heat generated by the power module 12. Since a plurality of air ducts 153 are formed between the plurality of heat dissipation fins 152, the plurality of air ducts 153 can effectively guide the hot air to flow outward, thereby achieving efficient heat dissipation.
[0036] With reference to Figure 6 The application further provides a refrigeration unit 1 comprising the electric control box 10 described in any of the above embodiments. The refrigeration unit 1 further comprises a shell 17, and the electric control box 10 is arranged in the shell 17.
[0037] In an embodiment, with continued reference to Figure 6 The shell 17 is provided with an air inlet 171 and an air outlet (not shown in the figure). The air inlet 171 is arranged close to the electric control box 10, and the air outlet is provided with an air outlet fan 18 capable of discharging air in the shell 17 to the outside. The cold air outside the refrigeration unit 1 enters the shell 17 from the air inlet 171. Since the air inlet 171 is arranged close to the electric control box 10, the cold air entering from the air inlet 171 first exchanges heat with the electrical devices in the electric control box 10, and then flows in the direction of the air outlet fan 18 under the action of the air outlet fan 18. Finally, the hot air after heat exchange is discharged to the outside of the shell 17 by the air outlet fan 18.
[0038] It should be noted that, in order to effectively dissipate heat of the heat generating devices in the shell 17, a plurality of air inlets 171 can be arranged, which can be arranged at the bottom or side of the shell 17. Figure 6It can be seen that, taking the bottom air inlet 1712 arranged at the bottom of the shell 17 and the side air inlet 1711 arranged at the side of the shell 17 as an example, the bottom air inlet 1712 and the side air inlet 1711 simultaneously take in air and exchange heat with the electric control box 10, which can improve the heat exchange efficiency.
[0039] It should be further noted that when the electric control box 10 includes the radiator 15, the fan 151 at the bottom of the radiator 15 also sucks air, and when the fan 151 is turned on, the air outside the shell 17 enters the shell 17 from the air inlet 171 and is first sucked by the fan 151 to the position for heat exchange with the electric control box 10, and the hot air after heat exchange flows outward through the air duct 153, while the air outlet fan 18 is also in an open state and sucks the air after heat exchange to the air outlet, and the air after heat exchange also continuously exchanges heat with other components in the shell 17 during flowing to the air outlet, thereby effectively cooling the electrical devices in the shell 17.
[0040] In addition, the application also provides a vehicle having the electric control box 10 described in any of the above embodiments, or comprising the refrigerating machine unit 1 described in any of the above embodiments.
[0041] The above only describes the preferred embodiments of the application and is not intended to limit the application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the application shall be included in the protection scope of the application.
