Embodiment 1
[0062] refer to figure 1 and figure 2 , a sealed heat conduction type outdoor power cabinet, comprising a cabinet body 1 and an opening and closing door arranged on the cabinet body, a heat exchange mechanism and a control module 3 are arranged on the cabinet body, a temperature sensor 4 is arranged in the cabinet body, The control module is electrically connected to the temperature sensor,
[0063] The heat exchange mechanism includes a heat insulation layer 102 arranged inside the enclosure wall 101 of the cabinet body, a thermal contact 5 passing through the insulation layer and connected to the enclosure wall of the cabinet body, and connecting with the enclosure wall of the cabinet body. The rotary heat conduction module matched with the heat conduction contact, the rotary heat conduction module includes a heat conduction sheet 6, the heat conduction sheet is connected with the drive motor 8 through the rotating shaft 7, the drive motor is arranged in the cabinet, and t...
Embodiment 2
[0090] The sealed and heat-conducting outdoor power cabinet of this embodiment is basically the same as that of Embodiment 1, except that:
[0091] refer to image 3 , the heat conducting sheet 6 is connected to the rotating shaft 7 through the elastic member 2 .
[0092] The elastic part can be made of rubber, so that the elastic contact between the heat conducting sheet and the rotating shaft can be realized through the elastic part, avoiding the hard contact phenomenon caused when the rotating shaft rotates, and also ensuring the stability of the contact.
Embodiment 3
[0094] The sealed and heat-conducting outdoor power cabinet of this embodiment is basically the same as that of Embodiment 1, except that:
[0095] The aluminum alloy is made of the following components in mass percentage:
[0096] Mg: 2.8%;
[0097] Si: 4.2%;
[0098] Mn: 0.28%;
[0099] Cr: 0.16%;
[0100] Zr: 0.23%;
[0101] Ti: 0.38%;
[0102] Yb: 0.25%;
[0103] The balance is Al and impurities with a content of ≤0.05%.
[0104] The preparation method of the aluminum alloy comprises the following steps:
[0105] Step S1: Carry out alloy smelting according to the above composition ratio, the alloy smelting temperature is 735°C, and keep warm for 10 minutes to obtain alloy melt 1;
[0106] Step S2: adding a refining agent to the obtained alloy melt 1 for refining, the refining temperature is 735° C., and the time is 12 minutes to obtain alloy melt 2;
[0107] Step S3: cooling and extruding the molten alloy 2 to obtain an ingot;
[0108] Step S4: raising the temper...
