Wearable portable air conditioning fan

Abstract

The invention provides a wearable portable air conditioning fan comprising a cold storage unit used for accommodating a cold source and provided with an opening in each of the bottom and the top, a thermal insulation bag used for wrapping the outside of the cold storage unit and provided with an air inlet in the bottom and a draught fan used for exhausting air entering from the air inlet from an air outlet formed in the top of the thermal insulation bag; the cold storage unit internally comprises a heat radiating unit which is arranged adjacent to the cold source and is longitudinally and uniformly distributed with a plurality of heat radiating fins; and an air flow passage is formed between every two adjacent heat radiating fins, wherein each of the heat radiating fins extends from the bottom to the top of the cold storage unit along the height direction, and an air flow in the air flow passage is blown out after being subjected to heat exchange through being in contact with the heat radiating fins. The wearable portable air conditioning fan provided by the invention has no special requirements for clothing and is light in weight, simple in operation and small in size so as to be portable, wearable and convenient to use.

Description

technical field [0001] The invention relates to a refrigeration device, in particular to a portable refrigeration device that can be worn around. Background technique [0002] The development of air-conditioning systems has solved the thermal comfort problem of most indoor environments, but its application is limited indoors; in many cases, humans must work in outdoor high-temperature environments, such as traffic police, construction site workers, fruit pickers, military personnel and others. Workers such as outdoor athletes. Working and living in a high temperature and high humidity environment often brings a strong sense of discomfort to people, and even endangers the safety of people's lives. [0003] In order to avoid heat stroke, it is necessary to take certain measures to cool and adjust the temperature of the microenvironment close to the human skin surface or under clothing. The existing technology provides two solutions for this: the first is to use the phase cha...

AI Technical Summary

Problems solved by technology

The first solution can only achieve the effect of cooling, but cannot dehumidify; while the second solution is difficult to achieve portable wearing effect due to the large pressure loss of the delivery pipe and the corresponding problems such as the inability to miniaturize the fan

Both of the above two solutions require custom-made specific clothing, and it is difficult to clean the clothing. You must wear this special clothing to achieve the cooling effect.
