Description

Technical Field

[0001] The present application relates to the technical field of water coolers, and in particular to a heat dissipation system of a water cooler. Background Art

[0002] A water-cooled chiller is a water-cooled chiller that uses water circulation to cool the refrigerant and dissipate heat. It is different from a basic water-cooled chiller in that it uses water instead of gas as the cooling medium to cool the compressor, condenser and other heat sources to maintain a stable operating temperature of the system.

[0003] When the water-cooled chiller is working, the cooling pipeline that needs to dissipate heat will pass through the cooling water tank. The cooling water tank stores circulating tap water, and the cooling pipeline is located in the circulating tap water for heat dissipation.

[0004] However, the closer the tap water in the cooling water tank is to the cooling pipe, the higher the water temperature is. The higher the tap water temperature is around the cooling pipe, the worse the cooling effect is. In order to ensure the cooling effect, it is necessary to shorten the circulation time of the tap water in the cooling water tank, which reduces the utilization rate of the tap water in the cooling water tank and causes energy waste. Utility Model Content

[0005] In order to improve the utilization rate of water resources in a heat dissipation water tank and save energy, the present application provides a heat dissipation system for a water-cooled machine.

[0006] The heat dissipation system of a water-cooling machine provided in the present application adopts the following technical solution:

[0007] A heat dissipation system of a water-cooling machine, comprising a heat dissipation water tank, a cooling coil, a compressed gas pipe group and an exhaust component;

[0008] A heat dissipation cavity for storing tap water is provided in the heat dissipation water tank, the cooling coil is located in the tap water in the heat dissipation cavity and is used for passing the fluid that needs to be cooled, the top and bottom of the heat dissipation cavity are provided with circulation pipes for connecting the water circulation components, the compressed gas pipe group is connected to a gas source for conveying compressed gas, the compressed gas pipe group is installed on the cavity wall of the heat dissipation cavity and is used for introducing compressed gas into the tap water, and the exhaust component is connected to the top of the heat dissipation cavity and is used for discharging the gas in the heat dissipation cavity.

[0009] By adopting the above technical solution, the cooling coil is cooled by tap water, and compressed gas is introduced into the tap water through the compressed gas pipe group, thereby stirring the tap water, increasing the water flow change speed around the cooling coil, making the tap water in the heat dissipation water tank in a flowing state, accelerating the heat dissipation of the cooling coil, thereby improving the utilization rate of water resources in the heat dissipation water tank and saving energy. At the same time, in order to stabilize the air pressure in the heat dissipation water tank, the excess gas is discharged through the exhaust component.

[0010] Optionally, the compressed gas pipe group includes a main air pipe and multiple jet pipes installed on the main air pipe, one end of the main air pipe is connected to the air source and the other end is arranged along the winding direction of the cooling coil, the multiple jet pipes are installed on the main air pipe at intervals along the winding direction of the cooling coil and are connected to the main air pipe, a single jet pipe is located between the pipe sections of two adjacent circles of the cooling coil, and multiple jet holes are opened on the side wall of the pipe section of the jet pipe facing the cooling coil.

[0011] By adopting the above technical solution, since there is an air jet pipe between the pipe sections of two adjacent circles of cooling coils, the collision force of the water flow near the cooling coils on the cooling coils and the change speed of the water flow are enhanced, the change speed of the tap water position in the entire radiator water tank is accelerated, and the temperature of the tap water in the radiator water tank is evenly distributed, thereby improving the utilization rate of the tap water in the radiator water tank.

[0012] Optionally, the jet pipe is arranged in a ring shape, the axis of the jet pipe coincides with the axis of the cooling coil, and the plurality of jet holes are arranged at intervals in the circumferential direction.

[0013] By adopting the above technical solution, when the jet hole injects compressed gas into the tap water, the tap water inside the cooling coil can move through the jet pipe. The jet holes are arranged at intervals in the circumferential direction, thereby expanding the injection area of ​​the compressed gas around the cooling coil, further accelerating the conversion speed of the tap water near the cooling coil.

[0014] Optionally, the exhaust assembly includes a first connecting pipe, a second connecting pipe and an exhaust fan;

[0015] An exhaust cavity is provided in the heat dissipation water tank, and the exhaust cavity is a spiral channel arranged vertically around the heat dissipation cavity. The two ends of the first connecting pipe are respectively connected to the top of the heat dissipation cavity and the top of the exhaust cavity. The second connecting pipe is installed at the bottom of the heat dissipation water tank and is connected to the bottom of the exhaust cavity. The exhaust fan is installed in the second connecting pipe and is used to guide the gas in the exhaust cavity to be discharged.

[0016] By adopting the above technical solution, as the compressed gas is continuously injected into the tap water, the air pressure in the heat dissipation cavity increases, and thus flows to the exhaust cavity. The exhaust fan can accelerate the speed of gas discharge in the exhaust cavity. The airflow of the gas moving around the heat dissipation cavity in the exhaust cavity can cool the cavity wall of the heat dissipation cavity, thereby slowing down the temperature rise rate of the tap water.

[0017] Optionally, heat dissipation fins are provided on the cavity wall of the exhaust cavity facing the heat dissipation cavity.

[0018] By adopting the above technical solution, the heat at the cavity wall of the heat dissipation cavity can be transferred to the heat dissipation fins, and the gas contacts the heat dissipation fins when flowing, thereby transferring part of the heat, thereby expanding the heat dissipation area of ​​the heat dissipation cavity.

[0019] Optionally, one end of the heat dissipating fin away from the cavity wall of the exhaust cavity is arranged obliquely in a direction opposite to the movement of the gas.

[0020] By adopting the above technical solution, the time that part of the gas stays near the heat dissipation fins during flow can be prolonged through the layout angle of the heat dissipation fins, further improving the heat dissipation effect on the temperature in the heat dissipation cavity.

[0021] Optionally, the second connecting pipe includes a first pipe section and a second pipe section that are connected to each other, the first pipe section is horizontally arranged and one end of the first pipe section is connected to the bottom of the exhaust chamber, the second pipe section is vertically arranged and the top end is connected to the other end of the first pipe section, and the exhaust fan is located in the first pipe section.

[0022] By adopting the above technical solution, the layout of the second connecting pipe can prevent dust from entering the exhaust chamber on the one hand, and on the other hand, the exhaust fan is protected, reducing the probability of dust clogging the second connecting pipe.

[0023] Optionally, the top end of the second pipe segment is threadedly connected to the other end of the first pipe segment.

[0024] By adopting the above technical solution, when too much dust accumulates in the second pipe section, the second pipe section can be disassembled for cleaning, thereby reducing the difficulty of maintaining the exhaust assembly.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. Compressed gas is introduced into tap water through the compressed gas pipe group to stir the tap water, increase the water flow conversion speed around the cooling coil, speed up the heat dissipation of the cooling coil, thereby improving the utilization rate of water resources in the heat dissipation water tank and saving energy;

[0027] 2. Since there is an air jet pipe between the pipe sections of two adjacent cooling coils, the collision force of the water flow near the cooling coil and the change speed of the water flow are strengthened, so that the temperature of the tap water in the heat dissipation water tank is more evenly distributed, and the utilization rate of the tap water is improved;

[0028] 3. During the process of introducing compressed gas, the gas in the heat dissipation chamber flows to the exhaust chamber. The gas moves around the heat dissipation chamber in the exhaust chamber to generate airflow, thereby cooling the cavity wall of the heat dissipation chamber to slow down the heating rate of the tap water.

[0035] The following is combined with Figure 1-4 This application is described in further detail.

[0036] It should be noted that, in the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0037] An embodiment of the present application discloses a heat dissipation system of a water chiller.

[0038] Reference Figure 1 and Figure 2 The heat dissipation system includes a heat dissipation water tank 1, a cooling coil 2, a compressed gas pipe group 3 and an exhaust component 4.

[0039] Among them, a heat dissipation chamber 11 for storing tap water is opened in the heat dissipation water tank 1, and the cooling coil 2 is located in the tap water of the heat dissipation chamber 11 and is used for passing the fluid that needs to be cooled. Therefore, the cooling coil 2 is usually connected to the cooling mechanism of the water cooler to facilitate the fluid that needs to be cooled to flow into the cooling coil 2.

[0040] The top and bottom of the heat dissipation cavity 11 are both provided with a circulation pipe 5 for connecting to a water circulation component. As the tap water cools down the cooling coil 2, the temperature of the tap water will also rise. In order to reduce the impact on the heat dissipation rate of the cooling coil 2, the water circulation component can replace the tap water that reaches a certain temperature. As long as the structure can replace the tap water in the heat dissipation water tank, it can be used as a water circulation component. Therefore, it is not displayed, and only the position of the circulation pipe 5 is displayed.

[0041] The compressed gas pipe group 3 is connected to a gas source for conveying compressed gas. The gas source can be a compressed gas tank storing compressed gas or an air compressor. The compressed gas pipe group 3 is installed on the cavity wall of the heat dissipation cavity 11 and is used to pass compressed gas into tap water and stir the tap water so that the tap water in the heat dissipation water tank 1 is in a flowing state, so as to increase the water flow conversion speed around the cooling coil 2, accelerate the heat dissipation of the cooling coil 2, thereby improving the utilization rate of water resources in the heat dissipation water tank 1 and saving energy.

[0042] At the same time, as the compressed gas is continuously injected, the air pressure in the heat dissipation cavity 11 will increase, and the exhaust component 4 is connected to the top of the heat dissipation cavity 11 so that the gas in the heat dissipation cavity 11 can be discharged to stabilize the water pressure in the heat dissipation water tank 1.

[0043] Reference Figure 2 and Figure 3 The compressed gas pipe group 3 includes a main gas pipe 31 and a plurality of injection pipes 32 installed on the main gas pipe 31 .

[0044] One end of the main air pipe 31 is connected to the air source and the other end is arranged along the winding direction of the cooling coil 2. A plurality of jet pipes 32 are installed at intervals on the main air pipe 31 along the winding direction of the cooling coil 2 and are connected to the main air pipe 31. A single jet pipe 32 is located between the pipe sections of two adjacent circles of the cooling coil 2. The jet pipe 32 is arranged in an annular shape, so that the jet pipe 32 has the same annular shape as the pipe section of the cooling coil 2. A plurality of jet holes 321 are opened on the side wall of the pipe section of the jet pipe 32 facing the cooling coil 2.

[0045] Since there is an injection pipe 32 between the pipe sections of two adjacent circles of cooling coils 2, when the injection holes 321 inject compressed gas into the tap water, the tap water inside the cooling coil 2 can move through the injection pipe 32. The injection holes 321 are arranged at intervals in the circumferential direction, thereby expanding the injection area of ​​the compressed gas around the cooling coil 2, further accelerating the conversion speed of the tap water near the cooling coil 2, and making the temperature of the tap water in the heat dissipation water tank 1 evenly distributed, thereby improving the utilization rate of the tap water in the heat dissipation water tank 1.

[0046] Reference Figure 2 and Figure 4 The exhaust component 4 includes a first connecting pipe 41 , a second connecting pipe 42 and an exhaust fan 43 .

[0047] The heat dissipation water tank 1 is provided with an exhaust cavity 12, which is a spiral channel arranged vertically around the heat dissipation cavity 11. The two ends of the first connecting pipe 41 are respectively connected to the top of the heat dissipation cavity 11 and the top of the exhaust cavity 12, so that the gas in the heat dissipation cavity 11 flows to the exhaust cavity 12. The second connecting pipe 42 is installed at the bottom of the heat dissipation water tank 1 and communicates with the bottom of the exhaust cavity 12. The exhaust fan 43 is installed in the second connecting pipe 42.

[0048] The exhaust fan 43 rotates to accelerate the exhaust of the gas in the exhaust chamber 12, which stabilizes the pressure in the heat dissipation chamber 11. On the other hand, the gas in the exhaust chamber 12 is accelerated to flow, and the gas moves around the heat dissipation chamber 11 and contacts the cavity wall of the exhaust chamber 12 close to the heat dissipation chamber 11, thereby cooling the cavity wall of the heat dissipation chamber 11 and slowing down the temperature rise of the tap water.

[0049] In order to further improve the heat dissipation effect on the cavity wall of the heat dissipation cavity 11 during gas flow, as shown in FIG. Figure 2 and Figure 3 As shown, a heat dissipation fin 6 is provided on the cavity wall of the exhaust cavity 12 facing the heat dissipation cavity 11 to increase the contact area with the airflow. The heat dissipation fin 6 is arranged at an angle in the opposite direction to the gas movement direction at one end of the cavity wall away from the exhaust cavity 12 to extend the time that part of the gas stays near the heat dissipation fin 6 when flowing, further improving the heat dissipation effect on the temperature in the heat dissipation cavity 11.

[0050] Since the second pipe section 422 leads to the outside of the heat dissipation water tank 1, dust is easily accumulated. Figure 4 The second connecting pipe 42 includes a first pipe section 421 and a second pipe section 422 which are connected to each other. The first pipe section 421 is arranged horizontally and one end of the first pipe section 421 is connected to the bottom of the exhaust chamber 12. The second pipe section 422 is arranged vertically and the top end is threadedly connected to the other end of the first pipe section 421. The exhaust fan 43 is located in the first pipe section 421.

[0051] This arrangement can prevent dust from entering the exhaust chamber 12, and protect the exhaust fan 43, reducing the probability of dust blocking the second connecting pipe 42. The exhaust fan 43 can be replaced and repaired by removing the second pipe section 422, thereby reducing the maintenance difficulty of the exhaust assembly 4.

[0052] The implementation principle of the heat dissipation system of a water-cooled machine in an embodiment of the present application is as follows: when the cooling coil 2 is dissipated, compressed gas is introduced into the tap water through the compressed gas pipe group 3 to stir the tap water, thereby accelerating the heat dissipation of the cooling coil 2. At the same time, the exhaust fan 43 is turned on, and the gas overflowing the tap water moves to the exhaust chamber 12. As the gas moves and contacts the heat dissipation fins 6, the cavity wall of the heat dissipation cavity 11 is cooled, thereby improving the utilization rate of water resources in the heat dissipation water tank 1 and saving energy.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
