[0026] Please refer to Figure 1 , the present utility model provides a cooling system with adjustable coolant boiling point for cooling a heat source device. The cooling system 100 with adjustable coolant boiling point in this embodiment is a fully closed refrigerant system, and the refrigerant is a working fluid, taking water as an example, but not limited thereto. The cooling system 100 with adjustable coolant boiling point includes a cavity 1, a fluid injection system 2, a vacuum device 3, a control unit 4 and a control valve 5.

[0027] The cavity 1 is a hollow body, and a chamber 11 is provided inside the cavity 1. The cavity 1 has an inlet 12 and an outlet 13, and the inlet 12 and the outlet 13 are respectively communicated with the chamber 11, so that the working fluid can be input into the chamber 11 through the inlet 12 and output through the outlet 13. The working fluid can also be regarded as a coolant. The cavity 1 is an evaporator, and the cavity 1 can contact or be close to the heat source device, so that the high temperature of the heat source device can be transferred to the cavity 1. The heat source device can be arranged inside or outside the cavity 1, and the heat source device is not limited. The heat source device can be, for example, a heating furnace, or an electronic device or a machine device, etc., which needs to be cooled and dissipated. The number of the inlet 12 and the outlet 13 is not limited. For example, two or three or more inlets 12 and outlets 13 can also be provided.

[0028] The fluid injection system 2 is connected to the inlet 12 of the cavity 1. The fluid injection system 2 can transport the working fluid from the inlet 12 into the chamber 11. The fluid injection system 2 can transport the working fluid in the form of water mist or liquid into the chamber 11, and the state of the working fluid is not limited. The vacuum device 3 includes a vacuum pump and the like. The vacuum device 3 is connected to the outlet 13 of the cavity 1. The vacuum device 3 is electrically connected to the control unit 4, and the operation of the vacuum device 3 can be controlled by using the control unit 4. For example, the switch and rotation speed of the vacuum device 3 can be controlled. When the vacuum device 3 is started, it can evacuate the chamber 11 through the outlet 13, so that the pressure in the chamber 11 decreases, and the boiling point of the working fluid in the chamber 11 can be decreased, enabling the working fluid to boil and vaporize more rapidly. The working fluid in the chamber 11 undergoes a phase change, changing from the liquid phase to the gas phase, and can absorb a large amount of heat, so as to provide a cooling and heat dissipation effect for the heat source device. According to the Clausius-Clapeyron equation, the relationship between the boiling point temperature and the vapor pressure of a single-component liquid is dP / dT = L / TΔV, where dP / dT is the rate of change of pressure with temperature, L is the latent heat, T is the phase equilibrium temperature, and ΔV is the change in specific volume during the phase change. Therefore, the purpose of regulating the boiling point temperature can be achieved by regulating the pressure.

[0029] The working fluid extracted through the outlet 13 of the cavity 1 can flow back to the cavity 1 through the vacuum device 3 and the fluid injection system 2. The structure of the fluid injection system 2 is not limited. In this embodiment, the fluid injection system 2 may include a heat exchanger 21, a water tank 22, and a delivery pump 23. The heat exchanger 21 is connected to the vacuum device 3, the water tank 22 is connected to the heat exchanger 21, and the delivery pump 23 is connected between the water tank 22 and the inlet 12 of the cavity 1. The working fluid extracted through the outlet 13 of the cavity 1 can be transported to the heat exchanger 21 through the vacuum device 3. The heat exchanger 21 can condense the vapor discharged from the vacuum device 3 into a liquid working fluid, and then transport the liquid working fluid to the water tank 22 for storage. Then, the liquid working fluid can be transported to the inlet 12 of the cavity 1 through the delivery pump 23, and an atomizing head 24 can be provided at the inlet 12, so that the working fluid can be transported into the chamber 11 in the form of water mist through the atomizing head 24.

[0030] The control valve 5 is connected to the inlet 12 of the cavity 1. The control valve 5 can be arranged between the delivery pump 23 and the inlet 12 of the cavity 1. The control valve 5 is electrically connected to the control unit 4. The control unit 4 can send control signals to control the control valve 5 so as to control the working fluid delivered to the inlet 12 of the cavity 1. The control valve 5 can be an on / off valve or a proportional valve, capable of controlling the injection amount of the working fluid, enabling the control unit 4 to perform on / off or opening degree control through the control valve 5. The control unit 4 can also control the operation of the vacuum device 3 to control the vacuum degree and temperature in the cavity 1.

[0031] In this embodiment, a pressure gauge 6 and a thermometer 7 can also be provided in the chamber 11. The pressure gauge 6 and the thermometer 7 are electrically connected to the control unit 4. The thermometer 7 can be used to detect the temperature in the chamber 11 for temperature control. The pressure gauge 6 can be used to detect the pressure in the chamber 11 for pressure control. The control unit 4 is a main control system, capable of detecting the pressure and temperature in the cavity 1, and enabling the cavity 1 to maintain the target temperature or pressure through the control of the vacuum device 3 and the control valve 5.

[0032] Please refer to Figure 2 The cooling system 100 with adjustable coolant boiling point in this embodiment is a fully open refrigerant system. When water is used as the refrigerant, since water is a harmless substance and can be directly discharged, the heat exchanger can be omitted to reduce the volume and cost. This embodiment is generally the same as the above first embodiment. The main difference is that the working fluid (vapor) drawn out through the outlet 13 of the cavity 1 can be directly discharged into the atmosphere through the vacuum device 3 without being recycled, so there is no need to set up the heat exchanger 21 in the above embodiment. The fluid injection system 2 of this embodiment includes a water tank 22 and a delivery pump 23. The water tank 22 can be filled with the working fluid (such as water), and then the liquid working fluid can be delivered to the inlet 12 of the cavity 1 through the delivery pump 23, so that the working fluid is delivered into the chamber 11. The water tank 22 can be provided with a water injection valve 8 and a liquid level gauge 9. The liquid level gauge 9 can be used to detect the liquid level of the working fluid in the water tank 22. When the liquid level is too low, the working fluid can be added through the water injection valve 8.

[0033] Please refer to Figure 3, the coolant boiling point adjustable cooling system 100 of this embodiment is a semi-open refrigerant system. This embodiment is substantially the same as the above first embodiment. In this embodiment, the fluid injection system 2 includes a heat exchanger 21, a water tank 22, and a delivery pump 23. The heat exchanger 21 is connected to the vacuum device 3, the water tank 22 is connected to the heat exchanger 21, and the delivery pump 23 is connected between the water tank 22 and the inlet 12 of the cavity 1. The working fluid extracted from the outlet 13 of the cavity 1 can be transported to the heat exchanger 21 through the vacuum device 3. The heat exchanger 21 can condense the vapor discharged from the vacuum device 3 into a liquid working fluid, then transport the liquid working fluid to the water tank 22 for storage, and then the liquid working fluid can be transported into the inlet 12 of the cavity 1 through the delivery pump 23. This embodiment mainly sets a gas-liquid separator 10 between the heat exchanger 21 and the water tank 22, which can directly discharge the vapor into the atmosphere, so a smaller heat exchanger 21 can be used. Only part of the vapor discharged from the heat exchanger 21 condenses, and after being separated by the gas-liquid separator 10, the condensed working fluid flows into the water tank 22 for collection. The water tank 22 can also be provided with a water injection valve 8 and a liquid level gauge 9. The liquid level gauge 9 can be used to detect the liquid level of the working fluid in the water tank 22. When the liquid level is too low, the addition operation of the working fluid can be performed through the water injection valve 8.

[0034] Please refer to Figure 4 , this embodiment discloses a heating furnace 200. The heating furnace 200 includes a heating zone 201 and a cooling zone 202. The heating zone 201 can heat the component to be heated by means of electric heating or the like. The cooling zone 202 is arranged at the downstream position of the heating zone 201. The cooling zone 202 can be used to cool the component to be heated that has been heated. The coolant boiling point adjustable cooling system 100 of the present utility model is arranged in the cooling zone 202. The coolant boiling point adjustable cooling system 100 can provide the cooling and heat dissipation effect for the cooling zone 202.

[0035] Please refer to Figure 5, this embodiment discloses a heating furnace 200, which includes a heating zone 201 and a cooling zone 202.

The cooling system 100 with adjustable coolant boiling point of the present invention is arranged in the cooling zone 202, and the cooling system 100 with adjustable coolant boiling point can provide the cooling and heat dissipation effect of the cooling zone 202. In this embodiment, the vacuum device 3 is mainly connected to the heating zone 201. Therefore, the vacuum device 3 can also be used to evacuate the heating zone 201 of the heating furnace 200 before each activation of heating, so that when the protective gas such as nitrogen is injected into the heating zone 201 of the heating furnace 200, the consumption of the protective gas can be reduced. A valve body 20 can also be arranged between the vacuum device 3 and the heating zone 201 to open and close the operation of evacuating the heating zone 201 of the heating furnace 200 by the vacuum device 3.

[0036] Please refer to Figure 6 and Figure 7 , the inlet 12 of the cavity 1 can also be of a drip type design, and the heat source device 300 is close to the inlet 12 of the cavity 1. When the fluid injection system 2 transports the working fluid from the inlet 12 to the chamber 11, the working fluid can drip onto the heat source device 300 or near the heat source device 300, so that the working fluid can be closer to the heat source device 300 and provide a more preferable cooling and heat dissipation effect. In this embodiment, the heat source device 300 can be arranged in the cavity 1.

[0037] The cooling system with adjustable coolant boiling point of the present invention can change the boiling point of the working fluid by changing the pressure in the chamber, and there is no high-pressure part in the cooling system. The working fluid in the cooling system can exist in a liquid state at room temperature and can be condensed and recovered under atmospheric pressure. On the contrary, the refrigeration compression system cannot use a liquid that is liquid at normal temperature and pressure (such as pure water with a boiling point greater than 25°C) as the working fluid. The refrigeration compression system operates in a refrigerant closed system. The cooling system of the present invention can operate in both a closed or open system. The refrigeration compression system is high-pressure (compressed) condensation, and the cooling system of the present invention is low-pressure (evacuated) evaporation.
