DETAILED DESCRIPTION

[0038] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0039] Example 1

[0040] A specific embodiment of the present invention, as Figure 1 As shown, the present invention discloses a low-pressure constant temperature heat dissipation device, comprising a low-pressure constant temperature heat dissipation mechanism 1, a pipeline 2 and a mechanism to be cooled 3, the low-pressure constant temperature heat dissipation mechanism 1 is connected to the mechanism to be cooled 3 through the pipeline 2, the low-pressure constant temperature heat dissipation mechanism 1 can maintain a low-pressure environment to make the water temperature constant, the low-pressure constant temperature heat dissipation mechanism 1 flows low-temperature water into the mechanism to be cooled 3 through the pipeline 2, the water absorbs the heat of the mechanism to be cooled 3, and the water then flows back to the constant temperature heat dissipation mechanism 1 through the pipeline 2.

[0041] In this embodiment, the low-pressure constant temperature heat dissipation mechanism 1 transports water to the mechanism to be cooled 3, the water flows through the mechanism to be cooled 3, and then takes away the temperature of the mechanism to be cooled 3, the water with increased temperature flows back to the low-pressure constant temperature heat dissipation mechanism 1 through the pipeline 2, the low-pressure constant temperature heat dissipation mechanism 1 evaporates the water with increased temperature into water vapor, and the water vapor is discharged into the external environment, thereby maintaining the low-pressure constant temperature state in the low-pressure constant temperature heat dissipation mechanism 1. This process utilizes the low-temperature evaporation heat absorption characteristics of water to solve the heat dissipation problem. The heat is directly discharged into the external environment in the form of water vapor, and no secondary heat dissipation device is required. This structure is simple, easy to operate and low in cost; and the low-pressure constant temperature heat dissipation mechanism 1 can adjust the pressure and then adjust the water temperature to meet the needs of different water temperatures.

[0042] The low-pressure constant temperature heat dissipation mechanism 1 includes a water storage circulation unit 11, and the water storage circulation unit 11 and the mechanism to be cooled 3 form a closed loop through the pipeline 2. Furthermore, the water storage circulation unit 11 includes a water tank 111 and a water pump chamber 113. The water pump chamber 113 is connected to the bottom of the water tank 111. The water tank 111 is used to store water, and the water pump chamber 113 is used to transport water to the mechanism to be cooled 3 through the pipeline 2. The heated water in the mechanism to be cooled 3 flows back into the water tank 111 through the pipeline 2, thereby forming a closed loop.

[0043] A water inlet 112 is provided on the top of the water tank 111 , and the water inlet 112 is connected to the sealing cover by threads. Water can be replenished in time through the water inlet 112 , and the water tank can be inspected and maintained through the water inlet 112 .

[0044] A first through hole is provided at the bottom of the water tank 111 , and the water pump chamber 113 is connected to the water tank 112 through the first through hole; further, a second through hole is provided on the side wall of the water tank 111 .

[0045] The water pump chamber 113 includes a water pump 114, which is arranged in the water pump chamber 113. The water pump 114 is provided with a water inlet pipe and a water outlet pipe. The water inlet of the water inlet pipe is connected to the water tank 111 through the first through hole at the bottom of the water tank 111, and the water outlet pipe of the water tank 111 is connected to the pipeline 2.

[0046] In this embodiment, the water pump 114 drives the water in the water tank 111 to circulate in the cooling mechanism 3 and the water tank 111 through the pipeline 2. The water in the water tank 111 absorbs heat through the cooling mechanism 3 and its temperature increases. The water with increased temperature flows back into the water tank 111 and brings heat into the water tank 111. The water in the water tank 111 absorbs heat and then enters a boiling state, and the liquid water turns into water vapor.

[0047] A maintenance port is also provided on the side of the water pump chamber 113 to facilitate maintenance of the water pump 114 .

[0048] In this embodiment, the water tank 111 and the water pump 114 are independently arranged, so as to facilitate the separate maintenance of the water tank 111 and the water pump 114. Furthermore, the water pump 114 can be arranged in the water tank 111, and the structure is simpler.

[0049] The low-pressure constant temperature heat dissipation mechanism 1 also includes a low-pressure constant temperature heat dissipation unit 12, which is connected to the water storage circulation unit 11. The low-pressure constant temperature heat dissipation unit 12 can adjust the pressure in the water tank 111. Since the boiling point of water changes with pressure, the low-pressure constant temperature heat dissipation unit 12 can adjust the boiling point of water by adjusting the pressure in the water tank 111.

[0050] The low-pressure constant temperature heat dissipation unit 12 also includes a vacuum pump 121, which is used to extract water vapor in the water tank 111 to keep the pressure in the water tank 111 constant, thereby ensuring that the water temperature in the water tank 111 remains constant; the vacuum pump 121 can quickly extract heat to achieve constant temperature control.

[0051] The vacuum pump 121 includes an air suction pipe and an air exhaust pipe. The air suction pipe is connected to the water tank 111 through the second through hole, and is used to connect the water tank 111 and the vacuum pump 121.

[0052] The low-pressure constant temperature heat dissipation unit 12 also includes a waterproof breathable valve 122. The exhaust pipe of the vacuum pump 121 is connected to the water tank 111 through the waterproof breathable valve 122. The water level in the water tank 111 is lower than the installation position of the waterproof breathable valve 122, which helps prevent water from entering the vacuum pump 121 and causing damage to the vacuum pump 121.

[0053] Furthermore, the waterproof breathable valve 122 can pass gas, and the waterproof breathable valve 122 blocks the passage of liquid, thereby ensuring that the vacuum pump 121 extracts air and water vapor from the water tank 111. Even when the water level in the water tank 111 is above the waterproof breathable valve 122, water will not enter the exhaust pipe of the vacuum pump 121 through the waterproof breathable valve 122, so as to improve the reliability of the vacuum pump 121 and prevent the vacuum pump 121 from sucking in a large amount of water, which may cause damage to the vacuum pump 121 and instability of the pressure and water temperature in the water tank 111.

[0054] The exhaust pipe of the vacuum pump 121 is directly connected to the external environment, and the water vapor is directly discharged into the external environment, which can increase the humidity of the external environment.

[0055] The low-pressure constant-temperature heat dissipation mechanism 1 further includes a power supply unit 13 , which is connected to the vacuum pump 121 and the water pump 114 .

[0056] The power supply unit 13 is provided with a multi-position switch 133, which is used to control the power supply on the one hand and the vacuum degree of the vacuum pump 121 on the other hand to adjust the pressure in the water tank 111 to meet the requirements of different water temperatures.

[0057] Specifically, the multi-position switch 133 can be set to three, four, five or six gears, corresponding to different vacuum degrees of the vacuum pump 121 and the pressure in the water tank 111 under different vacuum degrees, thereby controlling the boiling point of water.

[0058] Exemplarily, the multi-position switch 133 has four positions, namely "0", "1", "2" and "3", and "0", "1", "2" and "3" correspond to the required boiling points of water of 20°C, 21°C and 22°C respectively. When the multi-position switch 133 is at "0", it indicates that the power is disconnected and the vacuum pump is turned off; when the multi-position switch 133 is at "1", it indicates that the power is on, the vacuum pump is turned on and the boiling point of water is controlled to be 20°C; when the multi-position switch 133 is at "2", it indicates that the power is on, the vacuum pump is turned on and the boiling point of water is controlled to be 21°C; when the multi-position switch 133 is at "3", it indicates that the power is on, the vacuum pump is turned on and the boiling point of water is controlled to be 22°C.

[0059] The power supply unit 13 includes a battery box 131 and a battery 132 . The battery 132 is installed in the battery box 131 . The battery box 131 is connected to the vacuum pump 121 and the water pump 121 through wires to form a control loop. The battery 132 provides power for the vacuum pump 121 and the water pump 121 .

[0060] The battery box 131 is provided with a battery box switch door for replacing batteries.

[0061] In this embodiment, when the water inlet 112 is sealed, the low-pressure constant temperature heat dissipation mechanism 1 is a closed mechanism, wherein the water storage circulation unit 11, the low-pressure constant temperature heat dissipation unit 12 and the power supply unit 13 are placed in the same closed box, which is convenient for carrying and storage, and the low-pressure constant temperature heat dissipation mechanism 1 is in a closed environment to ensure the pressure stability in the water tank 111.

[0062] The pipeline 2 includes a water outlet pipeline 21 and a water return pipeline 22 .

[0063] The pipeline 2 further includes a first quick-connect plug 23 and a second quick-connect plug 24 . Specifically, the first quick-connect plug 23 is installed on the water outlet pipeline 21 , and the second quick-connect plug 24 is installed on the water return pipeline 22 .

[0064] In this embodiment, the first quick-connect plug 23 and the second quick-connect plug 24 are connectors with a cut-off function. The first quick-connect plug 23 and the second quick-connect plug 24 cooperate to control the closed circuit of the low-pressure constant temperature heat dissipation mechanism 1 and the mechanism to be cooled 3, and can quickly close and disconnect the closed circuit of the low-pressure constant temperature heat dissipation mechanism 1 and the mechanism to be cooled 3.

[0065] When the cooling mechanism 3 needs to be cooled, the first quick-connect plug 23 and the second quick-connect plug 24 are respectively connected to the cooling mechanism 3 and the water tank 111. At this time, the pipelines are connected, and the low-pressure constant temperature heat dissipation mechanism 1 and the cooling mechanism 3 form a closed loop, so as to reduce the temperature of the cooling mechanism 3. When the cooling of the cooling mechanism 3 is completed, the first quick-connect plug 23 and the second quick-connect plug 24 are respectively separated from the cooling mechanism 3 and the water tank 111. At this time, the pipelines are cut off, and the low-pressure constant temperature heat dissipation mechanism 1 and the cooling mechanism 3 can be separated, which is convenient for storage and carrying.

[0066] A channel for water to pass through is provided in the mechanism to be cooled 3 , so that the water can take away heat and reduce the temperature of the mechanism to be cooled 3 .

[0067] Optionally, the mechanism to be cooled 3 can be a box, protective clothing, etc., so as to cool down electronic components that need to be cooled, people wearing protective clothing for high-temperature operations, etc., and this low-pressure constant temperature heat dissipation device is small in size and light in weight, which is beneficial for cooling down people wearing protective clothing, and the device and the box can be carried and moved anytime and anywhere.

[0068] The present invention adopts a vacuum pump 121 to form a low-pressure environment in the water tank 111, ensuring that the water in the water tank 111 remains at a low temperature and that the water can evaporate continuously under low temperature conditions. The water with increased temperature after passing through the cooling mechanism 3 flows back into the water tank 111 to evaporate and release heat. The vacuum pump 121 continuously discharges heat to the external environment, thereby increasing the humidity of the external environment.

[0074] Step 4: After the heat dissipation is completed, turn off the multi-position switch 133.

[0075] The details are as follows:

[0076] In step 1, first put the water pump 114 into the water pump chamber 113, and the water inlet pipe of the water pump 114 is connected to the water tank 111 through the first through hole of the water tank 111; then the air inlet pipe of the vacuum pump 12 is connected to the water tank 111 through the waterproof air valve 122; then fill the water tank 111 with water through the water filling port 112; finally, connect the first quick-connect plug 23 and the second quick-connect plug 24 to connect the pipeline 2, that is, the low-pressure constant temperature heat dissipation mechanism 1 is connected to the mechanism to be cooled 3 through the pipeline 2, and wait for the power to be turned on.

[0077] In step 2, the required boiling point of water is first determined, the multi-position switch 133 is adjusted to the position of the required boiling point of water, the power supply unit 13 is turned on, and the low-voltage constant temperature heat dissipation device starts to work.

[0078] In step 3, the water pump 114 draws the water in the water tank 111 into the pipeline of the mechanism to be cooled 3 through the water outlet pipeline 21. The water takes away the heat of the mechanism to be cooled 3. The water temperature rises and then enters the water tank 111 through the return pipeline 22. The water in the water tank 111 boils and the liquid water turns into water vapor. The generated water vapor is discharged into the external environment through the air inlet pipe of the vacuum pump 121, thereby keeping the pressure and water temperature in the water tank 111 unchanged.

[0079] In step 4, after the cooling mechanism 3 has completed heat dissipation, the first quick-connect plug 23 and the second quick-connect plug 24 are disconnected. At this time, the low-voltage constant temperature heat dissipation mechanism 1 and the cooling mechanism 3 are no longer connected. Then, the multi-position switch 133 is adjusted to "0", the power supply unit 13 is turned off, the water pump 114 and the vacuum pump 121 are no longer working, and the cooling mechanism 3 and the low-voltage constant temperature heat dissipation mechanism 1 are stored separately.

[0082] 2. The heat of the present invention is directly discharged into the external environment in the form of water vapor, which can increase the humidity of the external environment and does not require a secondary heat dissipation device. This structure is simple, easy to operate and low in cost.

[0083] 3. The present invention utilizes the low-temperature evaporation heat absorption characteristics of water to solve the heat dissipation problem. The latent heat of vaporization of water is large and the heat dissipation lasts for a long time. The entire device consumes little power and is small in size, light in weight, and easy to carry.

[0084] 4. The present invention adopts a waterproof breathable valve to improve the reliability of the vacuum pump, and prevent the vacuum pump from sucking in a large amount of water, thereby preventing the vacuum pump from being damaged and the pressure and water temperature in the water tank from being unstable.

[0085] 5. The water temperature designed by the present invention is only related to the pressure in the water tank. A vacuum pump is used to keep the pressure in the water tank at a constant value, thereby keeping the water temperature unchanged, so that the heated water can flow back into the water tank to evaporate and release heat, making cooling easy to operate and simplifying the structural layout, so that the low-pressure constant temperature heat dissipation device has a simple structure, a small size, and is easy to carry.
