Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling, in particular to a human body temperature regulating device. Background Art

[0002] Liquid cooling systems have been widely used in several industries, such as the electronics industry. Chinese patents with announcement numbers CN109769376B, CN104703449B, and CN207476093U have already disclosed liquid cooling systems, but these patents are applied to cooling occasions in data centers. Taking the Chinese patent with announcement number CN109769376B as an example, it discloses a liquid cooling system based on evaporative cooling technology, including a liquid cooling server unit placed inside a computer room, a plate heat exchanger, and an evaporative cooling chiller. The two sides of the liquid cooling server unit are respectively connected to one end of the secondary water system supply pipe and the secondary water system return pipe, and the other ends of the secondary water system supply pipe and the secondary water system return pipe are both connected to the plate heat exchanger, and a secondary water system water pump is provided on the secondary water system supply pipe. The patented liquid cooling system uses an indirect cold plate liquid cooling server. The indirect cold plate is attached to the top of the server chip. The heat generated by the chip is taken away by the flow of water in the indirect cold plate. It has high cooling efficiency and is easily accepted by the market. The evaporative cooling chiller uses an indirect-direct evaporative cooling method to produce cold water below the ambient wet-bulb temperature, and is widely used in data centers with liquid cooling servers.

[0003] It can be seen that industrial chillers have been widely used in cooling systems in data centers, but such cooling systems are not widely used in manufacturing environments. According to the applicant's research, workers working in relatively closed, narrow, high-temperature or extremely cold scenes will greatly affect their work efficiency, and their comfort level is extremely low; under normal circumstances, intermittent work can improve workers' comfort, but work efficiency will be affected; improving the overall space temperature through refrigeration equipment such as air conditioners can also improve comfort, but the waste of cold air in some spaces makes the overall efficiency low and energy consumption high. As people's requirements for work efficiency and working environment comfort become higher and higher, efficient, convenient and comfortable human body temperature regulation systems are also becoming more and more popular.

[0025] The following will be combined with the attached embodiment of the present utility model Figure 1-2 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-2 As shown, a distributed human body temperature regulating device is characterized by comprising:

[0027] Liquid cooling suit 6, each worker wears a set of liquid cooling suit 6, which is equipped with heat exchange pipes for cold flow / hot flow. Liquid cooling suit 6 can move freely with the worker within a certain range. Liquid cooling suit 6 can have a variety of design options (not limited to the types listed in this embodiment). It is a hooded vest as a whole, and the inner and outer layers are made of thinner thermal conductive materials. The middle layer is arranged with silicone water pipes as heat exchange pipes. At the main parts of human body heat dissipation - torso and head, the heat exchange pipes are divided into four paths and arranged and covered at the same time. This path achieves a relatively good heat exchange effect with a smaller coverage area, and realizes the regulation of human body temperature;

[0028] A variable frequency chiller 1 that can provide cooling / heating capacity of different powers according to demand. The chiller 1 is an existing component (its internal configuration is also an existing solution). The selected type is Tongfei MCW-35 (or other types). The chiller 1 can provide cold water at a minimum of 15°C by exchanging heat with the environment. A certain flow of cold water is delivered to each liquid cooling suit 6 by a water pump. The cold water flow rate allocated to each liquid cooling suit 6 is related to the number of liquid cooling suits 6 simultaneously connected to the system. The liquid cooling suit 6 exchanges heat with the human body to achieve regulation of the human body temperature. The chiller 1 is equipped with a flexible output pipeline and a return pipeline. The water outlet end of the chiller 1 is connected to the water inlet end of the heat exchange tube of the liquid cooling suit 6 through the output pipeline, and the return end of the chiller 1 is connected to the water outlet end of the heat exchange tube of the liquid cooling suit 6 through the return pipeline.

[0029] Among them, the chiller 1 includes a refrigeration mechanism and a cold / hot water output mechanism connected to the refrigeration mechanism, and also includes a main controller that controls its working state. The cold / hot water output mechanism is connected to the output pipeline. The refrigeration mechanism uses a variable frequency compressor to provide different cooling capacities or heating capacities required by different numbers of liquid cooling clothes 6. Compared with the start and stop control of a fixed frequency compressor, it is more energy-saving and efficient, and the control is more precise.

[0030] As a preferred embodiment, in order to improve the pipeline docking scheme, the above-mentioned liquid cooling suit 6 is installed with a water inlet interface and a water outlet interface connected to the water inlet end and the water outlet end of its heat exchange tube. The water inlet interface of the liquid cooling suit 6 is detachably connected to the output pipeline of the chiller 1, and the water outlet interface of the liquid cooling suit 6 is detachably connected to the return pipeline of the chiller 1.

[0031] As a preferred embodiment, the output pipeline / return pipeline of the chiller 1 includes:

[0032] A collecting water pipe 2 directly connected to the chiller 1;

[0033] The flow dividing component 3 (equivalent to the flow dividing valve) has an input end connected to the collecting water pipe 2 and also has a plurality of output ends;

[0034] A plurality of flexible liquid cooling water pipes 7 are connected one by one with the output ends of the diversion components 3. Each liquid cooling water pipe 7 is provided with a quick connector 5 connected to the interface of the liquid cooling suit 6. The quick connector 5 enables the liquid cooling suit 6 to be quickly connected to the chiller 1 in the preparation stage.

[0035] Among them, the liquid cooling water pipe 7 belonging to the output pipeline of the chiller 1 is detachably connected to the water inlet interface of the liquid cooling suit 6, and the liquid cooling water pipe 7 belonging to the return pipeline of the chiller 1 is detachably connected to the water outlet interface of the liquid cooling suit 6.

[0036] As a preferred embodiment, the liquid cooling water pipe 7 is connected with a control valve 4 for controlling the flow which is easy to operate manually, so that a single worker can flexibly adjust the cold water / hot water flow according to his or her own physical condition, thereby achieving the purpose of flexibly adjusting the temperature.

[0037] Cold water is output from the chiller 1, and firstly guided to the vicinity of the use end through the collecting water pipe 2 with a larger inner diameter, and then divided into a number of liquid cooling suits 6 for use by people through the diversion component 3 near the use end. By connecting the chiller 1 and the liquid cooling suit 6 in this way, the resistance in the water flow process can be reduced, thereby increasing the flow rate and enhancing the heat exchange effect of the liquid cooling suit 6. After the cold water is diverted, a control valve 4 is set in the section of the liquid cooling water pipe 7 close to the liquid cooling suit, and the user can manually adjust the cold water flow according to the actual feeling to achieve the best effect. By connecting the liquid cooling suit 6 and the diversion component 3 through the quick connector 5, the user can increase or decrease the number of liquid cooling suits 6 connected to the system at the same time according to the needs.

[0038] As an optional solution, the liquid cooling water pipe 7 is connected with a temperature control valve 8 that automatically adjusts the flow rate according to the temperature. The temperature control valve 8 is a conventional component and can be used in combination with the control valve 4 or alone. When the water temperature is lower than the set value of the temperature control valve 8, the opening degree will be gradually reduced to achieve the purpose of controlling the flow rate of cold water. Automatically controlling the flow rate of cold water can prevent the liquid cooling suit 6 from being overcooled.

[0039] During use, the chiller 1 outputs cold water (or hot water) through the output pipeline. After the cold water (or hot water) passes through the liquid cooling service 6 for heat exchange, it flows back to the chiller 1 through the return pipeline, and circulates back and forth.

[0040] As a preferred embodiment, the liquid cooling suit 6 is built with a temperature sensor for real-time sensing of human body temperature, and the temperature sensor is electrically connected to the main controller of the chiller 1. In this embodiment, a temperature sensor patch is provided on the inner side of the vest of the liquid cooling suit 6, and the temperature sensor patch is electrically connected to the main controller of the chiller 1. The temperature sensor patch can monitor the body temperature of the user of the liquid cooling suit in real time, and transmit the temperature signal to the main controller of the chiller 1, and the main controller of the chiller 1 will automatically adjust the outlet water temperature accordingly.
