[0029] The specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings.

[0030] Example

[0031] Please refer to Figure 1 and Figure 2 , Figure 1 FIG. 1 is a schematic structural diagram of a silicon carbide workshop distribution box 100 provided in this embodiment at a first viewing angle. Figure 2 Shown is a schematic structural diagram of the silicon carbide workshop distribution box 100 at a second viewing angle.

[0032] The silicon carbide workshop distribution box 100 provided in this embodiment includes a box body 110, a heat-conducting mounting plate 120 and a fan 130. The heat-conducting mounting plate 120 is arranged in the box body 110, and the heat-conducting mounting plate 120 divides the interior of the box body 110 into an installation space 140 and a heat dissipation duct 150 that are not connected to each other. An electrical component 121 is arranged on one side of the heat-conducting mounting plate 120 corresponding to the installation space 140; the heat dissipation duct 150 has an air inlet end 151 and an air outlet end 152, the air inlet end 151 is at the bottom of the box body 110, and the air outlet end 152 is at the top of the box body 110, and the fan 130 is arranged at the air outlet end 152.

[0033] Due to the separation effect of the heat-conducting mounting plate 120, the installation space 140 and the heat dissipation duct 150 are independent of each other and are not connected to each other. The electrical component 121 is installed on the heat-conducting mounting plate 120 and is located in the installation space 140. In actual application, when the fan 130 is running, the air in the bottom area of ​​the box 110 is sucked into the heat dissipation duct 150 from the air inlet end 151, flows along the heat dissipation duct 150 to the air outlet end 152, and finally flows out of the box 110. In this process, the airflow in the heat dissipation duct 150 takes away the heat of the electrical component 121 through the heat-conducting mounting plate 120, thereby achieving heat dissipation of the electrical component 121. In addition, since the heat dissipation duct 150 and the installation space 140 are independent of each other, the heat-conducting dust in the airflow cannot enter the installation space 140, thereby preventing the electrical component 121 from being contaminated.

[0034] Considering that low-temperature air sinks and accumulates near the ground, in this embodiment, in order to obtain a better heat dissipation effect, the air inlet end 151 of the heat dissipation duct 150 is set at the bottom of the box 110, and the air outlet end 152 is set at the top of the box 110, so that when the fan 130 is running, the low-temperature air near the ground can be sucked into the heat dissipation duct 150. And as the airflow flows in the heat dissipation duct 150, the temperature gradually increases, and the airflow can float up along the heat dissipation duct 150 to avoid staying in the heat dissipation duct 150 for too long, thereby obtaining a better heat dissipation effect.

[0035] In this embodiment, in order to prevent the accumulation of heat-conducting dust in the heat dissipation duct 150 and affect the heat dissipation effect, and also to avoid causing dust in the workshop by flowing out of the air outlet 152 with the air flow, the silicon carbide workshop distribution box 100 provided in this embodiment also includes a dust collection component 160, and the dust collection component 160 is arranged at the air inlet end 151. The dust collection component 160 is used to collect dust in the air flow flowing into the air inlet end 151.

[0036] Please refer to Figure 3 , Figure 3 Shown is a schematic structural diagram of the dust collecting assembly 160.

[0037] The dust collection assembly 160 provided in this embodiment includes a filter pad 161 and a dust collection drawer 162. The filter pad 161 blocks the heat dissipation duct 150. The dust collection drawer 162 is located on the side of the filter pad 161 away from the air outlet end 152 and slidably cooperates with the box body 110. The opening of the dust collection drawer 162 faces the filter pad 161. A selectively openable flow window 1621 is provided on the bottom wall of the dust collection drawer 162. The dust collection drawer 162 is used to slide horizontally relative to the box body 110 under the action of external force to extend into or exit the heat dissipation duct 150.

[0038] It is understandable that the filter pad 161 plays a role in filtering the airflow, blocking the dust in the airflow from entering the heat dissipation duct 150. The dust drawer 162 plays a role in collecting dust, which is convenient for centralized treatment of dust. Specifically, when the fan 130 is running and the electrical component 121 is normally cooled, the flow window 1621 on the bottom wall of the dust drawer 162 is in an open state. At this time, the heat dissipation duct 150 is connected to the air inlet end 151 through the flow window 1621, and the airflow flowing in from the air inlet end 151 can flow through the flow window 1621 and the filter pad 161 to the air outlet end 152 in sequence.

[0039] After the fan 130 stops, the dust drawer 162 is pulled out of the housing 110 to process the dust collected in the dust drawer 162. In order to prevent dust from leaking when the dust drawer 162 slides relative to the housing 110, the flow window 1621 needs to be closed in advance. In this embodiment, the flow window 1621 is actually a shutter structure.

[0040] In order to further improve the dust removal effect of the dust collection component 160, in this embodiment, the dust collection component 160 further includes an electric dust removal module 1622, which is disposed in the dust collection drawer 162. When the airflow passes through the dust collection drawer 162, the electric dust removal module 1622 uses an electric field to separate the dust in the airflow from the airflow and attach it to the dust collection drawer 162.

[0041] Taking into account that a large amount of dust will adhere to the filter pad 161 in actual applications, in this embodiment, the dust collecting drawer 162 has a dust scraping side wall 1623, and the upper edge of the dust scraping side wall 1623 is in contact with the side of the filter pad 161 close to the air inlet end 151. The dust scraping side wall 1623 is used to scrape off the dust attached to the side of the filter pad 161 close to the air inlet end 151 when the dust collecting drawer 162 exits the heat dissipation air duct 150.

[0042] In order to further improve the heat dissipation effect of the heat dissipation duct 150 , in this embodiment, the silicon carbide workshop distribution box 100 also includes a water cooling plate 170 , which is arranged at the air inlet end 151 to cool the air flow flowing into the air inlet end 151 .

[0043] Please refer to Figure 4, Figure 4 FIG. 1 is a schematic structural diagram of the water cooling plate 170 .

[0044] The water cooling plate 170 includes a heat conducting plate body 171 and a water cooling tube 172 . The water cooling tube 172 is bent and extends on the heat conducting plate body 171 . The heat conducting plate body 171 covers the air inlet end 151 , and a plurality of air inlet holes 1711 are penetrated through the heat conducting plate body 171 .

[0045] It can be understood that in actual applications, the air at the bottom of the box 110 flows into the heat dissipation duct 150 through the air inlet hole 1711 on the heat conduction plate body 171. During this process, the low-temperature liquid in the water-cooling tube 172 absorbs the heat of the air through the heat conduction plate body 171, so that the temperature of the air flow flowing into the heat dissipation duct 150 is lower, further improving the heat dissipation effect on the electrical components 121.

[0046] In another embodiment, an evaporator may be used instead of the water cooling plate 170 , and the evaporator may be disposed at the air inlet end 151 and connected to an external refrigerant system so that the low-temperature refrigerant in the refrigerant system absorbs heat from the air flow flowing into the heat dissipation duct 150 at the evaporator.

[0047] In addition, the silicon carbide workshop distribution box 100 provided in this embodiment has a lifting leg 111 at the bottom of the box body 110, and the lifting leg 111 supports the box body 110. The lifting leg 111 is used to drive the box body 110 to move in the vertical direction to adjust the distance between the air inlet end 151 and the ground.

[0048] In addition, the silicon carbide workshop distribution box 100 also includes a temperature detection component, which is arranged in the installation space 140 and is used to detect the temperature of the installation space 140. The lifting legs 111 and the fan 130 are electrically connected to the temperature detection component.

[0049] It is understandable that when the temperature detection component detects that the temperature in the installation space 140 is too high, the speed of the fan 130 increases, and the lifting legs 111 drive the box 110 to rise, so as to increase the air intake volume of the air inlet end 151 and improve the heat dissipation effect. When the temperature in the installation space 140 detected by the temperature detection component is low, the speed of the fan 130 decreases, and the lifting legs 111 drive the box 110 to descend, so as to reduce energy consumption and lower the center of gravity of the box 110 to improve stability.

[0050] In summary, the silicon carbide workshop distribution box 100 provided in this embodiment can achieve heat dissipation for electrical components while preventing the electrical components 121 from being contaminated by conductive dust, and also has the characteristic of better heat dissipation effect.

[0051] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
