Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
An electric meter box with heat dissipation and dust removal functions is shown in figure 1 and comprises a meter box 1 and a meter box door 2, wherein a metal ventilation pipe 3 is arranged outside the meter box 1, two ends of the metal ventilation pipe 3 are communicated with the meter box 1, and hot air is light and is positioned at the upper part of the meter box 1; the cold air is heavy, is located the lower part of table case 1, consequently, the air inlet end of metal ventilation pipe 3 and the upper portion intercommunication of table case 1, the air-out end communicates with the lower part of table case 1. A ventilation fan (not shown) is arranged at the communication position of the air inlet end of the metal ventilation pipe 3 and the upper part of the meter box 1, and the ventilation fan blows air into the air inlet end of the metal ventilation pipe 3, so that the air in the meter box 1 circulates in the meter box 1 and the metal ventilation pipe 3.
Be provided with joint strip on table chamber door 2, after table chamber door 2 closed, form the airtight cavity of intercommunication in table case 1 and the metal ventilation pipe 3. The meter box door 2 is provided with a glass window through which an observer can observe the electric energy meter. Because the meter box 1 is closed, the influence of external dust, mosquitoes, flies and moisture entering the meter box 1 on the electric energy meter can be avoided.
Because the meter box 1 is closed, the problem of heat dissipation of the meter box is particularly important to solve. Therefore, the following measures are taken:
the heat dissipation water tank 4 is sleeved outside the metal ventilation pipe 3, and the heat dissipation water tank 4 is filled with heat dissipation liquid. The metal ventilation pipe 3 is made of aluminum and directly contacts with the heat dissipation liquid in the heat dissipation water tank 4 for heat dissipation. In order to reduce the temperature of the heat radiation liquid, a heat radiation fin is provided outside the heat radiation water tank 4, a cooling fan 5 is provided on the heat radiation fin, and the cooling fan 5 cools the heat radiation fin to cool the heat radiation liquid.
In high temperature in summer, it is not enough to just dispel the heat through heat dissipation water tank 4, is provided with the semiconductor refrigeration piece (not shown) in the air-out end of metal ventilation pipe 3, further cools off the air in the air-out end through the semiconductor refrigeration piece. The semiconductor refrigerating sheet has the advantages of small volume and easy control.
After the day is cold, the air in the meter box 1 does not need to be cooled, so that the cooling fan 5 and the semiconductor refrigerating sheet need to be turned off to save electric energy. Therefore, a temperature sensor (not shown) is arranged in the meter box 1, and the temperature sensor is connected with the cooling fan 5 and the semiconductor refrigeration piece. When the temperature in the meter box 1 is higher than the required temperature, the temperature sensor turns on the cooling fan 5 and the semiconductor refrigerating sheet for refrigeration; when the temperature in the meter box 1 is lower than the required temperature, the temperature sensor turns off the cooling fan 5 and the semiconductor refrigeration piece.
The details of which are not described in the prior art. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
