Between the outer body (1) and the inner body (2), which is the skeleton of the control helmet (A), to prevent condensation of cold air generated at the low temperature contact point of the thermoelectric semiconductor (7) and to prevent conduction to other places. The cooling plate 6 is installed, and the upper part of the cooling plate 6 has a high temperature in the direction of the current and the heat exchanger A 9 into which the coolant is injected to absorb the high temperature heat generated by the thermoelectric semiconductor 7.

Referring to the operating principle of the control helmet of the present invention configured as described above are as follows.

First, the worker's head has a control helmet; A heat sink on the back of the worker; When the power switch of the control means is turned on while the operator wears the control means on the waist of the worker, the Peltier effect of the thermoelectric semiconductor generates high temperature heat at the high temperature contact point according to the direction of the current, and at the low temperature contact point. Will absorb the heat.

According to the characteristics of the thermoelectric semiconductors as described above, the cold plate installed at the lower portion of the thermoelectric semiconductor is cooled to low temperature, and the cold air of the cold plate cooled to low temperature is changed to cooler cold by the cold plate, which is sucked from the air inlet. As the outside hot air passes through the cold / hot air space part, the hot air is cooled by the heat absorbed by the cold air emitted from the cold plate and the cold plate. On the other hand, high temperature heat is generated in the upper part of the thermoelectric semiconductor.

At this time, in order to continuously maintain low temperature cold air generated at the low temperature contact point of the thermoelectric semiconductor on the cold plate and the hot plate, and to continuously supply low temperature fresh air to the face of a person, high temperature heat generated at the high temperature contact point of the thermoelectric semiconductor Should be released to the outside.

The high temperature heat generated at the high temperature contact side of the thermoelectric semiconductor absorbs the high temperature heat primarily by the heat exchanger A in which the coolant is injected, and the high temperature coolant absorbed by the heat exchanger A is cooled by the flexible hose. The injected heat exchanger B is transferred to the heat exchanger B, and the high temperature cooling water transferred to the heat exchanger B is primarily radiated and cooled by a cooling fan. The cooled low-temperature cooling water is supplied to the heat exchanger A again through a flexible hose by a pump mounted on the outlet side of the heat exchanger B to secondarily absorb the high temperature heat generated from the hot contact side of the thermoelectric semiconductor, and the heat exchanger The high temperature cooling water absorbed in A is secondarily radiated and cooled by heat exchanger B and a cooling fan.

As the above circulation process is repeated, the low temperature contact point of the thermoelectric semiconductor is kept in a low temperature state, and thus the cold plate and the hot plate are continuously released with low temperature cold air, so that the outside hot air passing through the cold plate and the cold plate passes through the cold plate. The low temperature is changed into fresh air to provide fresh air to the face of the worker through the hot and cold air vent through the hot and cold air space.

By operating the controller 20 of the control means C, the power supplied to the fan motor 5, the thermoelectric semiconductor 7, the cooling fan 11, the pump 12, and the like for the air intake and discharge is controlled.

By maximizing the cooling effect at the low temperature contact point of the thermoelectric semiconductor, regardless of the surrounding environment such as temperature and humidity, it is possible to provide low temperature fresh air to the face of a person in a short time and to control the weight of the control helmet. And reducing the volume has an effect of making the wearer feel good.
