Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1-4:
a safe and energy-saving electric power cabinet for outdoor use comprises a cabinet body 1, wherein an air inlet drying device 3 and air extraction equipment are respectively arranged on two sides of the cabinet body 1, and a condensation device 2, a controller 5 and a humidity monitor 4 are arranged on the rear side of the cabinet body 1; the air inlet drying device 3 is composed of a drying box 31 filled with a solid desiccant 33, an electronic air inlet valve 34 is arranged at the top of the drying box 31, the bottom of the drying box 31 is communicated with the inside of the cabinet body 1 through a check valve 35, and the periphery of the solid desiccant 33 is coated with a semiconductor refrigeration sheet hot end 32; the condensation device 2 comprises a condensation box 21 communicated with the cabinet body 1 from the side surface, a condensation sheet 24 is vertically arranged at the rear side of the condensation box 21, the rear side of the condensation sheet 24 is adhered to a semiconductor refrigeration sheet cold end 23, the bottom side of the condensation box 21 is communicated with a water collecting groove 25, and a drain pipe 26 provided with an electric drain valve 261 is arranged at the bottom of the water collecting groove 25.
Semiconductor cooling fins are a means of heat transfer. When a current passes through a thermocouple pair formed by connecting an N-type semiconductor material and a P-type semiconductor material, heat transfer can be generated between the two ends, and the heat can be transferred from one end to the other end, so that temperature difference is generated to form a cold end and a hot end. But the semiconductor itself presents a resistance that generates heat when current passes through the semiconductor, thereby affecting heat transfer. But the heat between the two plates also passes through the air and the semiconductor.
The working principle is as follows: when the humidity monitor monitors that the humidity in the cabinet body exceeds the standard, the information is fed back to the controller, the controller starts the air inlet drying device 3 and the air extraction equipment, the electronic air inlet valve 34 is opened, the outside air flow enters the cabinet body after the solid desiccant adsorbs moisture, and the air in the cabinet body is exhausted. After the completion of taking a breath, keep the electron admission valve to open, check valve self-closing opens condensation device 2, and semiconductor refrigeration piece cold junction 23 absorbs the condensation piece heat and shifts to the semiconductor refrigeration piece hot junction 32 of drying cabinet, because the heat of the internal self production of cabinet can heat inside air, meets the condensation piece steam wherein that the temperature is low and will be at condensation piece upper surface gathering, then falls to the groove that converges to the internal gas of this drying cabinet. The heat from the hot end 32 of the semiconductor chilling plate heats the solid desiccant, completing regeneration of the solid desiccant for the next adsorption. When the humidity is controlled below the threshold, the electronic drain valve is opened to drain water, and the electronic air inlet valve 34 is closed to protect the solid dry adsorbent from absorbing moisture in the air and causing it to fail.
Specifically, the heat insulation plate 22 is laid on the side wall of the condensation device 2, so that the cold end 23 of the semiconductor refrigeration sheet can absorb heat of the condensation sheet 24 as much as possible.
Specifically, the condensation device 2 is installed on the upper portion of the cabinet body 1, and is concentrated on the upper portion of the cabinet body due to low density of hot air.
Specifically, the top of the drying box 31 is provided with a rain baffle plate to prevent rainwater from flowing backward, and the drying box can be used indoors without installation.
Specifically, the air extraction device is composed of a ventilation box 61 installed in the cabinet body 1 and an external ventilation pump 6, the ventilation box 61 increases the ventilation area, and the ventilation pump 6 provides negative pressure air extraction for the ventilation box 61.
Specifically, the water condensation sheet 24 is made of a steel sheet or glass, the condensation effect of the steel sheet or the glass is very good, and the material is common and easy to obtain.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
