The utility model has the following beneficial effects: the power distribution cabinet is in use, the oil liquid that refrigerating plant is fuel tank freezes, oil pump is driven Dynamic oil liquid circulates in fuel tank and heat exchanger, and the oil liquid after refrigeration absorbs heat in heat exchanger, meanwhile, air inlet fan drives air Into compartment, air-out fan drives air that compartment is discharged, exchanges heat when air passes through compartment with heat exchanger, air themperature drop Low, Cryogenic air is discharged into cabinet body again;The power distribution cabinet uses the mode of heat exchange for the electrical equipment heat dissipation in power distribution cabinet, has and dissipates The good advantage of thermal effect, and dust will not be sucked.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of power distribution cabinet of the utility model;
Fig. 2 is the structural schematic diagram of the mounting plate in the utility model.
Specific embodiment
The utility model is further described below with reference to embodiment, this is the preferred embodiment of the utility model.
As shown in Figs. 1-2, a kind of power distribution cabinet, the cabinet door 2 including cabinet body 1 and with the cabinet body 1 rotation connection, cabinet door 2 It is rotatablely connected by hinge and cabinet body 1.Installation cavity 11 is formed in the cabinet body 1, is distinguished on the side of the installation cavity 11 It is successively installed with heat exchanger 12 and mounting plate 13 from the inside to the outside, mounting plate 13 is spirally connected with cabinet body 1.The side of the installation cavity 11 The compartment 14 of sealing is formed between the mounting plate 13.The side of the cabinet body 1 is equipped with the oil connecting with the heat exchanger 12 Case 3, the fuel tank 3 are equipped with refrigerating plant and oil pump 5, and the refrigerating plant is that the oil liquid of the fuel tank 3 freezes.The oil 5 driving oil liquid of pump circulates in the fuel tank 3 and the heat exchanger 12.Air inlet fan is equipped at the top of the mounting plate 13 131, bottom is equipped with air-out fan 132.The air inlet fan 131 drives air into the compartment 14, the air-out fan The compartment 14 is discharged in 132 driving air.
For the power distribution cabinet in use, the oil liquid that refrigerating plant is fuel tank 3 freezes, oil pump 5 drives oil liquid in fuel tank 3 and heat exchanger It being circulated in 12, the oil liquid after refrigeration absorbs heat in heat exchanger 12, meanwhile, air inlet fan 131 drives air into compartment 14, out Wind fan 132 drives air that compartment 14 is discharged, and exchanges heat when air passes through compartment 14 with heat exchanger 12, and air themperature reduces, Cryogenic air is discharged into again in cabinet body 1.The power distribution cabinet uses the mode of heat exchange for the electrical equipment heat dissipation in power distribution cabinet, has and dissipates The good advantage of thermal effect, and dust will not be sucked.By the principle risen using hot-air, the setting of air inlet fan 131 is being pacified 13 top of loading board, the setting of air-out fan 132 make air circulation be more conducive to radiate in 13 bottom of mounting plate.
