Embodiment 1

[0031] Such as Figure 1 to Figure 5 Shown is a first embodiment of a cooling vest of the present invention. The cooling vest includes a vest 1, a refrigeration system, a circulation system, a control device 3, and a power supply 4; the refrigeration system includes a heat exchanger 5, semiconductor cooling fins 6, cooling fins 7 and a centrifugal fan 8; the circulation system includes a circulation pipeline and a water pump 9; The vest 1 is provided with an interlayer, and the circulation pipeline is buried in the interlayer, and the circulation pipeline is connected with the heat exchanger 5 .

[0032] In the cooling vest provided by the present invention, an interlayer is arranged in the vest 1. Under the action of the water pump 9, the water in the circulation pipeline can flow through the various parts of the vest 1. To cool down, the cooled cold water circulates again, and the cold water exchanges heat with the human body to reduce the core temperature of the human body...

Embodiment 2

[0039] Such as Image 6 Shown is the second embodiment of the present invention, this embodiment is similar to Embodiment 1, the difference is that, in this embodiment, the cooling vest also includes a smart bracelet 3a, and the smart bracelet 3a communicates with the control device 3 connect. The smart bracelet can be worn on the hands of the user of the cooling vest, which can assist in controlling the cooling vest through the bracelet and monitor the user's physical data in real time.

[0040] The smart bracelet 3a includes a temperature sensor, an optical heart rate sensor, a Bluetooth communication module, a display module and a control module. The temperature sensor can detect the surface temperature of the human body and the ambient temperature; the optical heart rate sensor can monitor the heart rate; the Bluetooth communication module can complete the connection with the control device 3 in the host 2 at a low cost; the display module can display the detection data, ...

Embodiment 3

[0042] This embodiment is similar to Embodiment 1. In this embodiment, since the circulating water needs to fill the circulating pipeline and surround the vest, a pipeline with a cross-sectional area of ​​1 square centimeter is used. If the length is 5 meters, 500 mL of pure water is required. That is, the weight is 0.5KG. After calculating the weight of the main unit 2 and the weight of the vest 1, the total weight is less than 2KG, and there is no obvious sense of weight after wearing it. Compared with the miniature fan blowing sweat and heat dissipation type and air compression refrigeration type cooling equipment, it is lighter. Due to the low water velocity of the circulation line, the water pump 9 with a power of 10W is sufficient to meet the circulation needs. The semiconductor cooling chip 6 with a single power of 60W is used, the maximum power of the two chips is 120W in total, and the cooling coefficient of the semiconductor cooling chip 6 is 0.6, which can better me...

Abstract

The invention relates to the field of protective equipment, and more specifically, relates to a cooling waistcoat. The cooling waistcoat comprises a waistcoat, a refrigerating system, a circulating system, a control device and a power supply, wherein the refrigerating system comprises a heat exchanger, semiconductor refrigerating plates, cooling fins and a centrifugal fan; the circulating system comprises a circulating pipeline and a water pump; the waistcoat with is provided with a sandwich layer, the circulating pipeline is buried in the sandwich layer; and the circulating pipeline is connected with the heat exchanger. According to the cooling waistcoat provided by the invention, the waistcoat is internally provided with the sandwich layer, water inside the circulating pipeline can flowthrough everywhere of the waistcoat under the effect of the water pump, when water flows through the heat exchanger, water is cooled through the semiconductor refrigerating plates, cold water after cooling is circulated again, heat exchange is carried out between cold water and a human body, and the core temperature of the human body is reduced. Water after the temperature of the human body is absorbed completely enters into the heat exchanger again, then is cooled again, and enters into next circulation.

Description

technical field [0001] The invention relates to the field of protective equipment, more specifically, to a cooling vest. Background technique [0002] Hot work environments are widely recognized to negatively impact the productivity of hot workers and affect workers' health. Taking front-line power workers as an example, in order to ensure the reliability of power consumption, it is often necessary to carry out live work outdoors, or carry out line construction in an open-air environment. In a high-temperature working environment, human physiological functions, especially body temperature regulation, water-salt metabolism, and blood circulation, are prone to problems. For example, profuse sweating will increase the burden on the cardiovascular system. When the high temperature environment exceeds the tolerance level of the human body, it will reduce work efficiency and affect the judgment at work, and cause heat stroke or more serious health problems. [0003] Therefore, i...
