Problems solved by technology

[0003] Some portable refrigeration devices in the prior art often require additional batteries for power supply, such as semiconductor refrigerators, and in the Chinese utility model patent with the publication number CN206507357U, a new cooling method using phase change materials for cooling is disclosed. Clothing, however, the phase change cooling process is uncontrollable, the phase change material will continue to absorb heat in the place that needs to be cooled, until there is no cooling capacity, it is difficult to achieve controlled cooling

Embodiment 1

[0046] refer to figure 1 and figure 2 , is an embodiment 1 of a portable self-controlled water absorption instant cooling device of the present invention, comprising a frame body 1, an anhydrous salt layer 2 that absorbs heat after contacting with moisture; the frame body 1 is hollow, and one side of the frame body 1 The wall is a hydrophilic heat-conducting layer 3 ;

[0047] Specifically, the anhydrous salt layer 2 may be one of sodium salt, potassium salt, calcium salt, ammonium salt, nitrate, chloride salt, sulfate, and sulfite, and ammonium salt is preferred in this embodiment. The frame body 1 is in the shape of a cuboid, and a hydrophilic heat-conducting layer 3 is installed on the side of the frame body 1 in the length direction.

[0048] In one embodiment, the side wall of the frame body 1 opposite to the hydrophilic heat conducting layer 3 is a hydrophobic heat insulating layer 4 , and the hydrophobic heat insulating layer 4 is detachably arranged on the frame bod...

Embodiment 2

[0054] refer to image 3 and Figure 4 , is Embodiment 2 of a portable self-controlled water absorption instant cooling device of the present invention, which differs from Embodiment 1 in that it also includes a water storage bag 6 for storing water, and the water storage bag 6 communicates with the inside of the frame body 1. When rapid cooling is required, the water in the water storage bag 6 is poured or squeezed into the frame 1, so that the large-area anhydrous salt layer 2 can quickly absorb water and a large amount of heat, thereby achieving the effect of rapid cooling.

[0055] In one of the embodiments, a water delivery pipe 7 is inserted into the water storage bag 6, and the water storage bag 6 communicates with the inside of the frame body 1 through the water delivery pipe 7, and a switch 8 for controlling the on-off of the water delivery pipe 7 is installed on the water delivery pipe 7. . Through the switch 8, the amount of water in the water storage bag 6 enteri...

Embodiment 3

[0066] refer to Figure 5 and Figure 6 , is Embodiment 3 of a portable self-controlled water absorption instant cooling device of the present invention, and its difference from Embodiment 2 is that it also includes a heat conduction element 11, and the heat conduction element 11 includes a cold end 111 and a heat end 112, and the cold end 111 and The hydrophobic and heat-conducting layers 12 are connected, and the heated end 112 extends away from the hydrophobic and heat-conducting layers 12 . Both the cold receiving end 111 and the heating end 112 are in a spiral shape.

[0067] When the cooling object is in a confined space and cannot be in direct contact with the external environment, for example, medical personnel wearing protective clothing place the heated end 112 inside the protective clothing, and place the rest of the device outside the confined space to be cooled, And open the switch 8, squeeze the water storage bag 6, make the water in it reach the surface of the...

Abstract

The invention relates to the technical field of refrigeration cooling equipment, in particular to a portable self-control water absorption instant cooling device and a using method thereof. The portable self-control water absorption instant cooling device comprises a frame body and an anhydrous salt layer which absorbs heat after making contact with water. The frame body is hollow, and a hydrophilic heat conduction layer is arranged on one side face of the frame body; the anhydrous salt layer is arranged in the frame body and makes contact with the hydrophilic heat conduction layer; when the anhydrous salt layer makes contact with sweat, the anhydrous salt layer absorbs heat in the water absorption process, and therefore, the temperature of the anhydrous salt layer is lowered, heat on the surface of the human body is promoted to be absorbed by the anhydrous salt layer; when the temperature of the human body is reduced to a proper level, the human body does not continue to perspire, and the anhydrous salt layer cannot continue to absorb moisture and does not continue to cool at the moment; and if the human body perspire again, the anhydrous salt layer absorbs moisture in sweat again for cooling at the moment, so that self-adaptive circulating cooling is formed.

Description

technical field [0001] The present invention relates to the technical field of refrigeration and cooling equipment, and more specifically, relates to a portable self-controlling water absorption instant cooling device and a usage method thereof. Background technique [0002] In daily life, there are often staff working in a closed environment, such as firefighters wearing fire suits to put out fires, inspectors wearing protective clothing, etc. Due to the closed environment, the heat in the body cannot be lost in time, and the heat from the outside may be input into the body, resulting in a rise in body temperature, the working environment is getting worse, and it is impossible to work efficiently for a long time. At the same time, for some on-duty personnel, who work in a hot environment for a long time, they also face a choice between continuing to work and their own health. In addition, in areas far away from the coverage of the national energy network, when faced with t...
