[0002] In a high temperature environment, human physiological functions, especially temperature regulation, water and salt metabolism, blood circulation and other functions will undergo abnormal changes. If the high temperature exceeds the human body's tolerance, it will reduce work efficiency and affect judgment at the least, and will cause heat stroke in severe cases, and even more serious cases will lead to sudden death. Existing firefighting cooling vests usually use heat exchange tubes to cool the user's skin. The heat of the coolant in the heat exchange tubes is dissipated through the heat sink, and the heat of the heat sink is dissipated faster by the fan. However, the heat dissipation efficiency of this type of heat dissipation method is very low in a high temperature environment. Even the external high temperature environment may heat the heat sink, causing the heat dissipation function of the cooling vest to fail and fail to meet usage requirements. Utility Model Content

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0024] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0025] In one embodiment of the present invention, Figures 1 to 6 As shown, a fire-fighting cooling vest is provided, comprising a vest body 1 and a heat exchange box 2, wherein an inner lining 11 is arranged in the vest body 1, and a plurality of heat exchange tubes 12 are distributed between the vest body 1 and the inner lining 11, and the heat exchange box 2 is detachably mounted on the bottom back of the vest body 1, wherein the heat exchange box 2 comprises a cooling chamber 21, a constant temperature box 22 and a water pump 23 for connecting the cooling chamber 21 and the constant temperature box 22, wherein the cooling chamber 21 is filled with ice cubes, and the constant temperature box 22 is filled with normal temperature water, and the head ends of the plurality of heat exchange tubes 12 are connected with the constant temperature box 22, and the middle parts pass through the back, shoulders, chest, flanks and waist of the vest body 1 in sequence, and the ends are connected with the cooling chamber 21.

[0026] Furthermore, a heat-conducting layer 13 is provided between the vest body 1 and the inner lining 11, and a plurality of the heat-exchange tubes 12 are clamped between the vest body 1 and the heat-conducting layer 13, and the heat-conducting layer 13 is fixedly connected to the inner lining 11. Specifically, the heat-conducting layer 13 is in the shape of a vest, but does not cover the vicinity of the zipper of the vest body 1, that is, the heat-conducting layer 13 located on the front part of the vest body 1 only covers the lateral abdomen of the lungs, so as to prevent the heat-exchange tubes 12 from cooling the navel of the user and causing discomfort to the user.

[0027] Furthermore, the outer wall of the heat exchange tubes 12 is provided with a reinforcing tube 121, and the reinforcing tube 121 is opened on the side in contact with the heat conductive layer 13, so that the heat exchange tube 12 is closely contacted with the heat conductive layer 13. Specifically, since the user usually needs to carry an oxygen cylinder on his back, the heat exchange tube 12 located on the back of the vest body 1 needs to bear pressure. In order to avoid the heat exchange tube 12 being deformed by pressure, resulting in poor circulation of cooling water, the reinforcing tube 121 can be used to bear the pressure of the oxygen cylinder, thereby avoiding the heat exchange tube 12 being deformed by pressure. At the same time, the heat exchange tube 12 can also be closely contacted with the heat conductive layer 13, thereby ensuring cooling efficiency.

[0028] Furthermore, the vest body 1 includes a fabric 3 , a waterproof layer 4 and a heat insulating layer 5 , and a plurality of heat exchange tubes 12 are clamped between the heat insulating layer 5 and the heat conducting layer 13 .

[0029] Furthermore, a waist belt 24 is fixedly connected to both sides of the heat exchange box 2, and a magic buckle 241 is provided between the waist belts 24 to achieve fixation. Specifically, after the user puts on the vest body 1, the heat exchange box 2 is fixed to the vest body 1 through the waist belt 24. After fixation, the heat exchange box 2 is located at the lower waist and hips of the user, avoiding the conflict between the heat exchange box 2 and the oxygen cylinder.

[0030] Furthermore, the heat exchange box 2 is provided with an insulation layer 211 and a sealed box plate 212. The insulation layer 211 covers the surface of the heat exchange box 2. An opening is provided on one side of the insulation layer 211. The sealed box plate 212 is hinged to the opening. Specifically, the insulation layer 211 can keep the ice cubes in the cooling chamber 21 warm and reduce the melting of the ice cubes due to the influence of external heat. By providing the sealed box plate 212, when ice cubes need to be placed in the cooling chamber 21, the sealed box plate 212 can be opened to fill the cooling chamber 21 with ice cubes, which is easy to operate.

[0031] Furthermore, a plurality of brackets 213 for placing ice cubes are arranged in sequence in the upper and lower parts of the cooling chamber 21, and a plurality of through holes 214 are designed to penetrate the brackets 213. Specifically, cooling water circulates into the cooling chamber 21, and the ice cubes cool and melt the cooling water. After being pumped by the water pump 23, the melted water in the cooling chamber 21 passes through the through holes 214 from bottom to top and enters the upper part of the cooling chamber 21, and is pumped by the water pump 23, thereby realizing the cooling cycle of the cooling water.

[0032] Working principle: When in use, the user wears the vest body 1 on the body, and the heat exchange box 2 is located at the user's hips, which is convenient for the user to wear the oxygen cylinder and avoid the conflict between the heat exchange box 2 and the oxygen cylinder. After entering the rescue site, the water pump 23 is started to pump the cold water formed by the melted ice in the cooling chamber 21 into the thermostat 22. The temperature of the cold water rises after passing through the thermostat 22, while the normal temperature water in the thermostat 22 releases heat and cools down, avoiding the cooling water with too low temperature from entering the heat exchange tube 12, and at the same time achieving the cooling water entering the heat exchange tube 1 2 has a relatively stable cooling water temperature, thereby improving the user's comfort. The normal-temperature water in the thermostatic box 22 is pumped into the heat exchange tube 12. The normal-temperature water flows through the back, shoulders, chest, flanks, and waist in the heat exchange tube 12 in sequence, and finally enters the cooling chamber 21 to be cooled by ice cubes, and then is pumped into the thermostatic box 22 by the water pump 23 for circulation. The heat exchange tube 12 passing through the flanks can have a better cooling effect on the user's abdomen, while avoiding the heat exchange tube 12 passing through the user's navel position to avoid discomfort to the user.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
