Description

Technology Field

[0001] The present invention relates to a heat-dissipating vest having a cooling system, and more specifically, to a heat-dissipating vest having a cooling system that is worn by a worker in a high-temperature environment to prevent a rise in body temperature. Background Technology

[0002] Recently, summers have tended to become hotter due to climate change. Consequently, in response to this climate change, heat-resistant vests and the like are being developed to provide coolness when worn on the body.

[0003] In addition, heat-resistant vests are worn at various industrial sites, work sites where air conditioning cannot be operated, or during outdoor activities to block external heat; they are also used as equipment to protect worker safety by preventing heatstroke caused by a rise in body temperature due to the heat.

[0004] A conventional cooling vest is configured with a structure in which a refrigerant pack pocket for accommodating a refrigerant pack (not shown), composed of a special refrigerant, is attached to the inner side of the vest, which is formed in a shape almost identical to a conventional one.

[0005] By being configured in this way, when a wearer wears the cooling vest with the refrigerant pack installed in the refrigerant pack pocket, the cooling vest delivers cold air to the wearer until all the refrigerant in the refrigerant pack undergoes a phase change to a liquid (or gel) state at room temperature, thereby allowing the wearer to maintain a cool state for a relatively long time. Therefore, it can be usefully utilized by users who need to work continuously in hot environments or users who need to lower their body temperature for various purposes such as medical use.

[0006] In order for the cold air from the cooling vest to be transferred efficiently, the surface of the cooling vest combined with the refrigerant pack pocket must be in close contact with the wearer's body.

[0007] Meanwhile, conventional cooling vests are merely vests formed in a shape almost identical to a standard vest with a refrigerant pack pocket attached to the inner surface; therefore, with such a structure, it was impossible to manufacture and provide cooling vests that could fit snugly to the bodies of all users, tailored to the diverse body sizes of various wearers.

[0051] Afterwards, the cooling heat conductive layer (646) of the low-temperature air supply member (64) is placed so that it comes into contact with the heat conductive coating layer (648) of the rear plate (3).

[0052] Therefore, the cooling heat of the cold air moving through the cold air supply passage (642) is transferred to the cooling heat conduction layer (646) and then rapidly transferred to the heat conduction coating layer (648) formed on the back plate (3), thereby allowing a cooling sensation to be transmitted to the wearer and improving cooling performance.
