Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are the best embodiments of the present invention.
As shown in fig. 1-2, a waterproof and anti-condensation electrical apparatus box comprises an electrical apparatus box body, the electrical apparatus box body comprises an upper casing 100 and a lower casing 200, a circuit board assembly 300, a main body 400 and an electronic device are mainly arranged in the electrical apparatus box body, the upper casing 100 is connected with the lower casing 200 in a buckling manner, a slot 101 is arranged on the upper casing 100, the slot 101 is arranged on the outer side wall of the upper casing 100, an inserting body 201 is arranged on the lower casing 200, and the inserting body 201 is arranged on the outer side wall of the lower casing 200. The sealing ring 500 is arranged on the surface of the lower shell 200, which is in contact with the upper shell 100, the sealing ring 500 is arranged to ensure the sealing performance of the electrical box body, and external water is prevented from flowing into the electrical box body from the joint of the upper shell 100 and the lower shell 200.
The upper shell 100 is a transparent upper shell made of a transparent material, the upper shell 100 is provided with a second heat dissipation port 102, the second heat dissipation port 102 is provided with a waterproof breathable film, the lower shell 200 is provided with a water guide groove 202 at a position corresponding to the second heat dissipation port 102, the second fan heat port 102 is arranged at the slot 101, the water guide groove 202 is arranged at the plug 201, the water guide groove 202 is arranged below the plug 201, and the water guide groove 202 is used for evacuating water dialyzed out from the waterproof breathable film. Waterproof ventilated membrane mainly used dispels main part 400 and the heat that electron device on the main part 400 produced, dispels the heat to electrical apparatus box body front portion, and the last casing 100 that reaches the electrical apparatus box body is transparent and do not have the condensation to exist, the utility model provides an electrical apparatus box body is high waterproof, some thermal stability is strong. The electronic devices on the main body 400 include a relay 401, a rupture disc.
The principle of waterproof and breathable of the waterproof breathable film is as follows: when the front part in the electrical box body generates water vapor due to temperature difference, the water particles of the water vapor are very fine, and the water particles can smoothly permeate to the other side of the capillary tube according to the capillary motion principle, so that the dialysis phenomenon is generated. When water vapor is condensed into water drops, the particles become bigger, and due to the surface tension effect of the water drops (mutual pulling and balancing among water molecules), the water molecules can not smoothly separate from the water drops and permeate to the other side, so that the water permeation is prevented, and the waterproof and breathable film has a waterproof function.
