Description

Technical Field

[0001] The present invention relates to the field of wearable devices, and in particular to a wearable semiconductor phase-change cooling garment. Background Art

[0002] People have their own isothermal zones, and in this temperature zone, they can maintain their normal body temperature by relying on physical regulation. If the ambient temperature continues to rise, the heat dissipation ability of people is blocked, and physical regulation alone can no longer maintain thermal balance. At this time, physical and chemical regulation must be initiated. When these adjustments cannot effectively maintain the thermal balance in the body, abnormal changes occur in human physiological functions, especially temperature regulation, water and salt metabolism, and blood circulation. For example, excessive sweating will increase the burden on the cardiovascular system. If the high temperature exceeds the tolerance of the human body, it will reduce work efficiency and affect judgment at the least, and cause heat stroke in severe cases, and even more serious cases will lead to sudden death. In order to solve the above problems, cooling and cold storage protective clothing came into being.

[0003] Most of the phase change cooling suits on the market use cold gel or phase change material as the cold source. This material is injected or inserted into the protective clothing, and the protective clothing can maintain the coldness for a certain period of time after being frozen. However, the disadvantage is that the gel will harden after freezing and will not fit the human body, seriously affecting the wearer's flexibility when moving. At the same time, all cooling suits need to be frozen and stored in advance, and cannot be used in emergencies. Moreover, once the energy stored in advance of all cooling suits is consumed, they will no longer have the cooling effect, which is the so-called usage time.

[0004] In summary, there is an urgent need for a wearable semiconductor phase change cooling suit that can get rid of the limitation of the use time of existing cooling suits. The cooling time can be extended by replacing the battery. While enhancing the comfort of the wearer, it optimizes the disassembly, assembly, and cold storage of the cooling suit before and after use. It can be cooled immediately after use, greatly improving the work efficiency of the wearer. Summary of the invention

[0005] The purpose of the present invention is to provide a wearable semiconductor phase change cooling clothing to solve the problems of the existing cooling clothing mentioned in the above background technology, such as short cooling time, inability to be used in emergencies, and over-reliance on designated cold sources.

[0010] There are multiple temperature probes installed on the cooling suit body and all connected to the digital temperature controller.

[0011] The cooling suit body comprises a cooling suit inner layer, a cooling suit middle layer and a cooling suit outer layer from inside to outside.

A heat dissipation fan is arranged above the corresponding semiconductor refrigeration unit, and a heat conduction fin is arranged between the heat dissipation fan and the semiconductor refrigeration unit.

[0018] The temperature probe is arranged below each semiconductor refrigeration unit and placed between the middle layer of the cooling suit and the inner layer of the cooling suit; or corresponds to the inner layer of the cooling suit of each semiconductor refrigeration unit.

[0020] A phase change temperature control layer is provided between the inner layer of the cooling suit and the middle layer of the cooling suit, and the temperature probe is provided in the phase change temperature control layer.

[0021] The phase change temperature control layer is formed by mixing sodium polyacrylate, carboxymethyl cellulose, expanded graphite and calcium chloride hexahydrate in a ratio of 4:3:1:12, and then stirring at 80° C. for 6 hours.

[0022] The present invention has the following beneficial effects and advantages:

DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative achievements are within the scope of protection of the present invention.

[0032] The present invention relates to a wearable semiconductor phase change cooling clothing, which is characterized by being a sleeveless vest-type structure, and comprising: a cooling clothing body 1, a digital temperature controller 4, a power supply 3, a zipper 6, a side waist 5, a cooling device 2 and a temperature probe 14; the digital temperature controller 4 and the cooling device 2 are respectively connected to the power supply 3;

[0033] The digital temperature controller 4 and the power supply 3 are both arranged on the front of the cooling suit body 1, and the power supply 3 is connected to the digital temperature controller 4; the front and back of the cooling suit body 1 are connected through the side waist 5;

[0034] The zipper 6 is arranged on the front side of the cooling suit body 1;

[0035] There are multiple cooling devices 2, all connected to the digital temperature controller 4, symmetrically arranged on both sides of the zipper 6, and a digital temperature controller 4 is provided on one side of the zipper 6, and a power supply 3 is symmetrically provided on the other side; the cooling device 2 is also arranged on the back side of the cooling suit body 1, and is arranged corresponding to the cooling device 2 on the front side.

[0036] There are multiple temperature probes 14 installed on the cooling suit body 1 and all connected to the digital temperature controller 4 .

[0037] The cooling suit body 1 adopts a vest-like design, and the left and right sides of the cooling suit body are connected by a zipper 6; the side waist 5 is made of elastic and wear-resistant fabric, specifically abaca fiber, glass fiber, and cashmere fiber.

[0038] The outer layer 7 of the cooling suit body is made of a material with good wear resistance, specifically carbon fiber, high-strength vinylon fiber and cashmere fiber; the middle layer 8 of the cooling suit is made of a material with low thermal conductivity, specifically aerogel; the inner layer 9 of the cooling suit is made of a material with good strength, flexibility, electrical and thermal conductivity and skin-friendly, specifically graphene and cashmere fiber.

[0039] Compared with traditional materials, aerogel can achieve better results with lighter weight and smaller volume. Aerogel has the advantages of heat insulation and high temperature resistance. The use of aerogel coating can effectively prevent the entry of external heat and the loss of internal coolness, thereby extending the cooling time. Graphene fiber blended material has excellent strength, flexibility, electrical and thermal conductivity, and also has the characteristics of long-lasting antibacterial. It is as moisture-absorbent and breathable as cotton, and is skin-friendly and comfortable to wear.

[0040] The cooling suit body 1 is provided with 6 cooling devices 2 on the front side and 8 cooling devices 2 on the rear side, which are evenly distributed. Each cooling device is composed of 2 sets of semiconductor refrigeration units 13 and a phase change temperature control layer 10.

[0041] The phase change temperature control layer 10 in the cooling device 2 is composed of a polymer phase change material that is temperature controllable, highly thermally conductive and flexible. The polymer phase change material used is a polymer phase change material that can control the temperature at 20-25°C without temperature fluctuations, and can bend, twist and deform at any temperature without losing material properties. Specifically, it is a mixture of sodium polyacrylate, carboxymethyl cellulose, expanded graphite and calcium chloride hexahydrate. Specifically, the phase change temperature control sheet is made of sodium polyacrylate, carboxymethyl cellulose, expanded graphite and calcium chloride hexahydrate in a ratio of 4:3:1:12, and then stirred at 80°C for 6 hours.

[0042] A temperature measuring probe 14 is embedded in the phase change temperature control layer 10, which can detect the temperature of the phase change temperature control layer (10) in a timely manner.

[0043] The power supply 3 and the digital temperature controller 4 are located below the cooling device 2 on the front side of the cooling suit body.

[0044] The digital temperature controller 4 can monitor the temperature of a designated position in real time, and is provided with a temperature control probe 14 to timely detect the temperature of the human body, and intelligently switch the semiconductor refrigeration unit 13 through temperature feedback, while also reflecting all data on the display screen 6.

[0045] The power supply 3 is designed to be capable of supplying direct current or alternating current.

[0046] The semiconductor refrigeration unit 13 is used to provide cooling capacity because of its high cooling efficiency and fast response. At the same time, the design that can be powered by both DC and AC can enhance the portability of the invention. By connecting a mobile charging device such as a power bank, the invention can be used and cooled immediately. At the same time, it also saves the energy loss of ordinary cooling clothing during transportation, and can meet the needs of long-term continuous cooling of the human body by replacing the battery. There is no need to freeze and store energy for the material in advance. It can be cooled immediately after power is turned on. The operation is simple, efficient and safe.

[0047] The working principle of the present invention is:

[0048] For the wearable semiconductor phase change cooling suit, when using it, first check that the cooling devices 2, the digital temperature control unit 4 and the power supply 3 in the cooling suit are well connected, and make sure that the power supply 3 is sufficiently charged. Then put on the cooling suit so that the inner layer 9 of the cooling suit fits the surface of the human body. Then turn on the power supply 3 to start the cooling device 2. First, charge the phase change cold storage material with cold, and use the phase change temperature control layer 10 to store cold and control the temperature so that the material reaches a suitable temperature, which solves the problem of rewarming and makes people feel comfortable while cooling the human body. At the same time, the digital temperature control unit 4 monitors the surface temperature of the human body in real time. If it is higher or lower than the warning temperature, the power-off protection is immediately executed to protect personal safety.
