Detailed Description

The present invention will be described in further detail with reference to the following examples:

a temperature control device of a high-power electrical method instrument transmitter is shown in figures 1-3 and comprises a refrigerating device 2 and a transmitter, wherein the refrigerating device 2 is connected with the transmitter 5 through a second connecting pipe 3, a fan 7 is arranged between the refrigerating device 2 and the second connecting pipe 3, and cold air generated by the refrigerating device 2 is sent into the transmitter 5 through the second connecting pipe 3 by the fan 7, so that the working environment temperature of the transmitter 5 is reduced, and the normal work of the transmitter 5 is ensured.

As shown in fig. 2, the refrigerating device 2 is a refrigerating sheet 6 disposed in the sealed box, the refrigerating sheet 6 is a refrigerating element generating negative thermal resistance, and the refrigerating element can continuously work without pollution source, rotation effect, reliability and noise. The box is sent into the air inlet through first connecting pipe 1 in the box, the box gives transmitter 5 through the cold air that second connecting pipe 3 produced with interior refrigeration piece 6 of box, be equipped with fan 7 between refrigeration piece 6 and the second connecting pipe 3 in the box, fan 7 set up can be smoothly send into the cold air that refrigerating plant 2 produced in the second connecting pipe 3, provide suitable operating temperature for transmitter 5 through second connecting pipe 3.

The first connecting pipe 1 and the second connecting pipe 3 can be telescopic aluminum foil air pipes, and are high in pressure resistance, flame-retardant, high in telescopic flexibility and easy to install.

As shown in fig. 1, a bamboo charcoal box 4 is disposed between the second connecting pipe 3 and the transmitter 5, the bamboo charcoal box 4 contains a filter element, and a drying agent is disposed in the filter element, so as to sufficiently dry and filter moist air, provide a comfortable working environment for the transmitter 5, and ensure the normal operation of the transmitter 5.
