Description

PORTABLE COOLING DEVICE FOR AIR JACKET < RTI ID = 0.0 >

The present invention relates to a portable cooling apparatus for an air jacket, and more particularly, to a portable cooling apparatus for an air jacket, in which a shipyard, a heavy industry, a steel structure producer, a paint maker, And to a portable cooling apparatus for an air jacket for lowering the temperature of compressed air supplied to a jacket by a compressor at a provided air jacket.

Air jackets are being used to protect workers and ensure the efficiency of operation in fire and heat environments such as shipbuilding, heavy industry, iron structure producers, painters, painters, and others. Such an air jacket is intended to prevent industrial accidents caused by an increase in body temperature of a worker (wearer) working in a high temperature space. By causing compressed air supplied from a compressor to be sprayed toward a human body of a worker, Evaporate and lower body temperature.

In general, an air jacket used by a welding worker such as a shipyard is constructed such that a hose is installed inside the jacket, and the compressed air supplied from the compressor is injected into the jacket by connecting the hose to the compressor.

On the other hand, in relation to the air jacket which allows the compressed air supplied from the compressor to be directly sprayed to the operator, a Korean Registered Utility Model No. 0471653 entitled "Jacket Air Supply Device ", registered patent No. 1120983 entitled" Air jacket using vortex tube " Patent No. 0930656 "jacket type personal cooling apparatus" and the like have been proposed. Such conventional techniques may be applied to a small fan (registered trademark) No. 0471653 entitled " jacket air supply device ", a vortex tube (registered patent No. 1120983 entitled "an air jacket using a vortex tube"), And a "jacket type personal air conditioner") to reduce the temperature of the air to provide a cooling effect.

However, such an air jacket according to the related art has a problem in that it is inconvenient to use. That is, although the portable cooling apparatus according to the related art is manufactured in a small size, it is inconvenient to wear it by an operator using a separate belt, waistband, or the like when actually using the portable cooling apparatus.

In addition, the portable cooling apparatus for the air jacket according to the related art can not stably provide the cooling efficiency of the air, and the air jacket has a problem of increasing the unit price, and thus it is practically difficult to apply. For example, in the case of applying a small fan, it is possible to construct an air jacket which does not require connection with a compressor, but it has a structure for circulating room air, so that it can not be applied in a harsh environment such as welding work of a shipyard. There is a problem that satisfactory cooling efficiency can not be provided. In the case of applying a vortex tube, it is difficult to maintain the cooling efficiency due to the loss of the air amount because a large amount of air introduced from the compreser is discharged into the warm air by the principle of the vortex tube and the warm air generated additionally is discharged to the outside There is a problem that an additional burden is imposed. When a small air conditioner is used, a problem of supply of power for operating the air conditioner occurs, and a problem of heat treatment generated in the condenser is additionally generated.

Accordingly, the present invention has been proposed in order to solve the problems of the prior art, and it is an object of the present invention to provide a method and apparatus for protecting a worker in a fire or heat environment such as shipyard, heavy industry, steel structure manufacturer, And it is an object of the present invention to provide a portable cooling apparatus for a new type air jacket capable of increasing the cooling efficiency of the air jacket.
