For example, in this case, the reinforcing part 13 may be attached to the protective clothing so as to be worn around the wearer's waist according to the rigidity of the material of the disposable protective clothing, thereby reducing the coupling member 10 and the portable cooling system 20. By distributing the weight, the protective clothing can be prevented from being damaged.

Furthermore, the coupling member 10 may be formed of a flexible and lightweight material to relieve wearer's discomfort.

The portable cooling system 20 is coupled to the mounting space 15b inside the mounting portion 15, cools the air inside the protective clothing, and discharges the cooled air back into the protective clothing to cool the air. External air is introduced through the internal circulation module 200 and the external air inlet 110 for circulation, but heat generated during air cooling of the internal circulation module 200 is transferred together with the external air introduced into the external air outlet ( 120) coupled between the external circulation module 100 discharged to the outside, the internal circulation module 200 and the external circulation module 100, and the air circulating through the internal circulation module 200 and the external circulation A blocking module 300 that blocks air circulating in the module 100 from each other and is coupled while penetrating the blocking module 300 cools the air inside the internal circulation module 200 and supplies it to the inside of the protective clothing 1 It may include a cooling module 500 that does.

That is, the portable cooling system 20 for protective clothing and the protective clothing 1 can block external air that does not pass through the portable cooling system 20 for protective clothing by sealing areas other than the external air inlet 110 and the external air outlet 120. can

Furthermore, the portable cooling system 20 for the protective clothing may include a sealing member 600 in a coupling area between the external air inlet 110 and the external air outlet 120 and the protective clothing 1. That is, the sealing member 600 is coupled with the coupling milling 17 of the protective clothing 1 by forming a ring-shaped concave groove 610 so as to be hermetically coupled with the coupling milling 17 provided in the coupling hole of the protective clothing 1. As a result, it is possible to further help in airtightness with the outside air.

The internal circulation module 200 may provide a second circulation space in which the second air circulation member 900 is located and cools and circulates the air inside the protective clothing 1, and the blocking module 300 is the external circulation module. Between (100) and the internal circulation module (200) can be coupled to be airtight. For example, a separate airtight member (not shown) is provided along the coupling area between the outer circulation module 100 and the blocking module 300 and between the blocking module 300 and the inner circulation module 200 for the stability of airtightness. can be combined

In addition, the blocking module 300 has a first air circulation member 400 coupled to one side and a second air circulation member 900 coupled to the other side, thereby providing a first air circulation member 400 in the first circulation space.

When current is applied to the thermoelectric element unit 520, thermoelectric cooling is performed through heat exchange. In the case of thermoelectric cooling, since a refrigerant and a compressor are not used, it is relatively free from noise and can be compact by reducing the size. In addition, since the thermoelectric cooling method enables temperature control through current control, power consumption can be efficiently achieved. For example, the cooling module 500 includes a heat exchange unit in the form of a metal foam with an increased specific surface area or a heat exchange unit using a metal wire, thereby increasing cooling efficiency and reducing weight.

When heat exchange is performed by the thermoelectric element unit 520, the heat dissipating unit 510 coupled to one side of the thermoelectric element unit 520 is relatively heated during heat exchange to the outside through the air moving in the first circulation space. may be released.
