Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting clothing, in particular to a directional heat dissipation type cooling work clothing for fire-fighting. Background Art

[0002] Fire suits are one of the important equipments to protect the personal safety of firefighters who are active in the front line of firefighting. They are not only an indispensable item at the fire rescue scene, but also a fire prevention tool to protect the firefighters from physical injuries. Therefore, fire suits suitable for fire rescue activities are particularly important.

[0003] Firefighters also need to wear cooling suits inside their fire suits during firefighting and rescue operations. The purpose is to lower body temperature, reduce heat stress and fatigue of firefighters in high temperature environments, and improve work efficiency and safety.

[0004] Currently, the cooling clothing on the market is mainly divided into several categories: air compressor cooling type, water cooling type, air cooling type and phase change material cooling type.

[0005] Air compressor cooling type cooling clothing and water cooling type cooling clothing products must be equipped with portable compressors, capillaries, condensation radiators, evaporative coolers, cooling water tanks, anti-overheating tanks and other devices. The clothing and equipment are connected through connecting structures. Cooling water pipes must be installed in the clothing to circulate cooling water to reduce the temperature of the clothing. This cooling method requires a fixed power supply as a power support, and there are problems such as the overall volume is too large, the load is too heavy, it affects the human body's movements, and restricts the individual's flexible movement. It is not suitable for firefighting and rescue scenes; the cooling unit of the phase change material cooling type cooling clothing is small in size and does not restrict individual movement, but the phase change material must be placed in a low temperature environment for a period of time before use to replenish cold energy, and the cold energy of this type of cold storage material cannot be maintained for a long time, resulting in a short effective cooling time of the cooling clothing, which cannot meet the working time requirements of the firefighting and rescue team; air-cooled cooling clothing mainly relies on fans to disperse wind to various parts of the human body, and the body's heat and sweat are discharged from the gaps in the clothing through the wind to achieve the purpose of relieving heat and cooling, but the cooling effect is not significant when used in high temperature scenes such as firefighting.

[0032] Example 1

[0033] like Figure 1-Figure 8 As shown:

[0034] A directional heat dissipation type cooling work clothes for fire fighting comprises a vest body 1, a pocket 17 is arranged on the vest body 1, and a heat dissipation port 18 for heat dissipation and exhaust is opened at the bottom hem of the vest body 1.

[0035] like Figure 4 As shown, the vest body 1 is composed of a flame retardant outer layer 2, a heat insulating layer 3 and a breathable inner layer 4 from the outside to the inside, and a semiconductor cooling module 16 installed on the heat insulating layer 3 is arranged between the flame retardant outer layer 2 and the breathable inner layer 4.

[0036] The heat dissipation opening 18 is connected to the space between the heat insulation layer 3 and the flame retardant outer layer 2. The provision of the heat dissipation opening 18 facilitates air circulation and heat dissipation between the heat insulation layer 3 and the flame retardant outer layer 2, thereby enhancing the cooling effect.

[0037] The flame retardant outer layer 2 is made of aramid flame retardant fabric, and the breathable inner layer 4 is made of nylon silk fabric.

[0038] like Figure 5As shown, the heat insulating layer 3 is composed of an outer anti-down cloth 5, an insulating flocculus 6 and an inner anti-down cloth 7 from the outside to the inside, and the outer anti-down cloth 5, the insulating flocculus 6 and the inner anti-down cloth 7 are connected by a quilting process.

[0039] like Figure 4-Figure 6 As shown, a mounting groove is opened on the thermal insulation layer 3, and the semiconductor cooling module 16 is arranged in the mounting groove and connected to the thermal insulation layer 3 through the flexible fabric 8. The flexible fabric 8 and the thermal insulation layer 3 are sewn together to form the semiconductor cooling module 16 and the thermal insulation layer 3 as a whole.

[0040] The flexible fabric 8 is in a square shape, the vertical projection area of ​​the flexible fabric 8 is larger than the vertical projection area of ​​the semiconductor cooling module 16 , and a slot is provided in the middle of the flexible fabric 8 .

[0041] The semiconductor cooling module 16 includes a semiconductor refrigeration sheet 10 , and a graphene cooling sheet 9 is installed on the inner side of the semiconductor refrigeration sheet 10 close to the human body.

[0043] The semiconductor cooling module 16 is connected to a power source that is detachably mounted on the vest body 1 . In this embodiment, the power source is a lithium power source 15 with a temperature adjustment button, and the lithium power source 15 is placed in a pocket 17 .

[0044] A cooling fan 12 is installed on the outer side of the pin-shaped heat sink 11 , and a protective mesh cover 13 is provided outside the cooling fan 12 .

The longitudinal semiconductor cooling modules 16 are staggered inwardly from top to bottom to facilitate heat dissipation. The semiconductor cooling modules 16 are connected by wires 14, and the wires 14 of the semiconductor cooling modules 16 on the front chest and back are connected across the shoulders.
