[0033] The following will detail this disclosure with reference to the accompanying drawings and in conjunction with embodiments.

[0034] Refer to Figures 1 to 6 As shown, the adaptive cooling electrical cabinet 100 of this application includes: a cabinet body 110, a cabinet door 120, a ventilation door 130, a door control assembly 140, etc.

[0035] Among them, the cabinet body 110 is formed with an inner cabinet space 111 for accommodating electrical components and a cooling channel for ventilation; the cabinet door 120 is rotatably connected to the cabinet body 110 about a first axis to open or close the inner cabinet space 111 of the cabinet body 110; the ventilation door 130 is rotatably connected to the cabinet body 110 about a second axis to open or close the cooling channel of the cabinet body 110; the door control assembly 140 is arranged inside the cabinet body 110 and is correspondingly arranged with the position of the ventilation door 130.

[0036] The main function of the cabinet door 120 is to open the inner cabinet space 111 of the cabinet body 110 when maintenance personnel are performing maintenance, while the function of the ventilation door 130 is to open when the temperature reaches a preset temperature, and together with the original ventilation window 112 of the cabinet body 110, etc., form an air flow to achieve cooling.

[0037] Among them, the door control assembly 140 includes: a base body 141, a piston rod 142, a support rod 143, a gas storage tank 144, a valve plate 145, a temperature-sensitive valve rod 146.

[0038] Specifically, the base body 141 is formed with an accommodation chamber 1411, a guiding channel 1412, and an air guiding channel 1413; the piston rod 142 is slidably disposed in the guiding channel 1412, and the support rod 143 is fixedly connected to the end of the piston rod 142; the gas storage tank 144 is formed with a gas storage chamber 1441 for storing the expansion working medium; the valve plate 145 is used to seal the gas storage chamber 1441; the temperature-sensitive valve rod 146 is connected to the valve plate 145 and is made of a shape memory alloy to pull the valve plate 145 to open the gas storage chamber 1441 at a preset temperature. The function of the base body 141 is to connect the control door assembly 140 into a whole. The accommodation chamber 1411 of the base body 141 is mainly used to accommodate the gas storage tank 144, the air guiding channel 1413 and the guiding channel 1412 are communicated, and the piston rod 142 and the support rod 143 actually constitute a piston mechanism.

[0039] As a specific solution, the first axis is perpendicular to the second axis. There are two ventilation doors 130, and the cabinet door 120 is disposed between the two ventilation doors 130. The ventilation doors 130 are provided at the bottom of the cabinet body 110, and the ventilation doors 130 are connected to the cabinet body 110 in a manner of turning outwards. A ventilation window 112 corresponding to the cooling channel is provided at the top of the cabinet body 110. This can form a relatively high air flow cycle. Due to the characteristic that the gas rises when heated, after the ventilation doors 130 are opened, it is equivalent to forming an air flow cycle from the ventilation doors 130 to the ventilation window 112.

[0040] The gas storage tank 144 can store temperature-sensitive gas, that is, the expansion coefficient is relatively high when the gas changes, so sufficient gas expansion can be generated. The valve plate 145 and the temperature-sensitive valve rod 146 constitute a one-way valve mechanism. The temperature-sensitive valve rod 146 includes a rod portion 1461 and a seat portion 1462. The rod portion 1461 is used to connect to the cover plate 1493; the seat portion 1462 forms a stepped groove, and the valve plate 145 is disposed in the stepped groove and is limited. The air pressure in the gas storage tank 144 will press the valve plate 145 in the stepped groove, so that the gas cannot be discharged, and the gas returning from the air guiding channel 1413 to the gas storage tank 144 will push the chip closer to the gas storage tank 144, thereby opening the return channel. And to open the output channel from the gas storage tank 144 to the air guiding channel 1413, it is necessary to reach the preset temperature so that the temperature-sensitive valve rod 146 contracts, so that the valve plate 145 is deflected to create a certain space for the gas to flow out of the gas storage tank 144. In this way, at high temperature, the gas storage tank 144 outputs gas to drive the piston rod 142 to push open the ventilation door 130, and when the temperature drops, the ventilation door 130 pushes the piston rod 142 back under the action of gravity, causing the gas volume to contract and flow back to the gas storage tank 144.

[0041] As a specific solution, the gas storage tank 144 is provided with an air outlet seat 1442; the control valve assembly 140 further includes: a connecting pipe 148 and an end cover 1491. Among them, the connecting pipe 148 is arranged between the gas storage tank 144 and the base body 141 to communicate the gas storage cavity 1441 and the air guide channel 1413. The end cover 1491 is combined with the air outlet seat 1442 to form a valve cavity 1492 for accommodating the valve plate 145 and the temperature-sensitive valve rod 146 as a whole.

[0042] As a specific solution, the control valve assembly 140 includes two groups of piston rods 142 and support rods 143; the gas storage cavity 1441 of the gas storage tank 144 is respectively communicated with two air guide channels 1413 through two connecting pipes 148.

[0043] As a specific solution, the control valve assembly 140 further includes: a cover plate 1493, fixedly connected to the base body 141 to close the accommodation chamber 1411; the top of the temperature-sensitive valve rod 146 is fixedly connected to the cover plate 1493 and forms a heat transfer connection therewith; several heat dissipation ribs 1494 are provided on the top of the cover plate 1493. This can better enable the temperature-sensitive valve rod 146 to exchange heat with the environment. The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the (but not limited to) technical features having similar functions disclosed in the embodiments of the present disclosure.
