Description

Technical Field

[0001] This utility model relates to the field of cooling water cooling technology, specifically a cooling water cooling device for air conditioning in a cleanroom. Background Technology

[0002] In modern industrial production, cleanrooms, as special production spaces with stringent requirements for environmental parameters such as air cleanliness, temperature, and humidity, are widely used in high-tech fields such as electronic chip manufacturing, biopharmaceutical research and development, and precision instrument processing. Their internal air conditioning systems play a crucial role in maintaining a stable environment, and the cooling water system, as an important component of the air conditioning refrigeration cycle, directly affects the cooling efficiency and operational stability of the air conditioning equipment. When the cleanroom air conditioning equipment is running, the cooling water continuously absorbs heat during circulation, causing its temperature to rise. If the heated cooling water cannot be cooled down in a timely and efficient manner, the air conditioning cooling capacity will decrease, thereby disrupting the temperature and humidity balance within the cleanroom and affecting product quality and the normal operation of production processes. Therefore, developing efficient and reliable cleanroom air conditioning cooling water cooling devices is essential to ensure the stable operation of cleanrooms and improve industrial production quality.

[0003] Traditional cleanroom air conditioning systems use chillers to cool the water. However, the refrigerant pipes are in direct static heat exchange contact with the heated cooling water. This heat exchange within a fixed heat exchange channel leads to insufficient heat exchange: uneven flow velocity occurs, resulting in water near the heat exchange wall exchanging heat effectively with the refrigerant, while the central area struggles to dissipate heat, causing heat accumulation and reducing overall cooling efficiency. Furthermore, the refrigerant's poor flow prevents it from fully absorbing heat from the cooling water, leading to incomplete evaporation and reduced refrigeration cycle efficiency. Therefore, a cleanroom air conditioning cooling water cooling device is needed to address these problems in existing technology. Utility Model Content

[0004] The purpose of this invention is to provide a cooling water device for air conditioning in cleanrooms to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling water device for air conditioning in a cleanroom, comprising:

[0006] A chiller body, wherein the chiller body is used to cool the cooling water of the purification workshop equipment;

[0007] A warm water tank, which is fixed in the equipment compartment of the chiller, is used to store cooling water.

[0008] A heat absorption mechanism is fixed inside the warm water tank. The heat absorption mechanism is used for uniform heat absorption by the refrigerant. The heat absorption mechanism includes a refrigerant heat absorption cylinder, which is fixed on the inner wall of the warm water tank.

[0009] Preferably, a refrigerant outlet pipe is connected and fixed to the upper part of the refrigerant heat absorption cylinder, and a refrigerant inlet pipe is connected and fixed to the lower part of the refrigerant heat absorption cylinder.

[0010] Preferably, bearings are embedded and fixed at the center of both ends of the refrigerant heat absorption cylinder, and a rotating shaft is rotatably connected inside the refrigerant heat absorption cylinder, with both ends of the rotating shaft passing through the bearings.

[0012] Preferably, a sealing seat is fixed to one end face of the refrigerant heat absorption cylinder, a drive motor is fixed to one end face of the sealing seat, and the output shaft of the drive motor is fixed to one end of the rotating shaft that passes through the sealing seat.

[0013] Preferably, a liquid supply pump is fixed to one side surface of the warm water tank, a refrigerant inlet pipe is provided at the front end of the liquid supply pump, a circulating refrigerant connector is fixed at one end of the refrigerant inlet pipe, the upper end of the refrigerant outlet pipe is connected to the evaporator in the chiller body, a return channel is provided between the circulating refrigerant connector and the condenser in the chiller body, and a warm water inlet pipe is fixedly connected to one end of the warm water tank.

[0014] This utility model provides a cooling water cooling device for air conditioning in a cleanroom, which has the following advantages compared with the prior art:

[0015] The heat absorption mechanism allows the refrigerant stirring blades to agitate the liquid refrigerant, improving the situation where the static refrigerant has a high temperature at the heat absorption cylinder and a low temperature at the center, resulting in uneven heat absorption. The agitation allows the refrigerant to circulate as a whole, ensuring that all refrigerant molecules are in uniform contact with the high-temperature cylinder wall, thus avoiding waste due to insufficient heat absorption in certain areas.

[0016] By using the set warm water stirring blades and refrigerant heat absorption cylinder, the warm water stirring blades can improve the fluidity of the warm water in the warm water tank. This can prevent the warm water near the outer wall of the refrigerant heat absorption cylinder from cooling down due to heat release, allowing the high-temperature warm water to remain close to the cylinder wall and ensuring that the heat from the heat source in the warm water tank is stably transferred to the cylinder wall.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a cooling water cooling device for air conditioning in a cleanroom, comprising:

[0024] Chiller 1, chiller 1 is used to cool the equipment in the purification workshop;

[0025] The warm water tank 2 is fixed in the equipment room of the chiller body 1 and is used to store cooling water. After the air conditioning equipment in the cleanroom is running, the cooling water that absorbs heat and rises in temperature is passed into the warm water tank 2 inside the chiller body 1 for storage.

[0026] The heat absorption mechanism 8 is fixed inside the warm water tank 2. The heat absorption mechanism 8 is used for uniform heat absorption by the refrigerant. The heat absorption mechanism 8 includes a refrigerant heat absorption cylinder 9, which is fixed on the inner wall of the warm water tank 2. When the chiller body 1 is working, the high-pressure liquid refrigerant flowing out of the condenser is throttled and depressurized by the expansion valve, and then transformed into a low-temperature and low-pressure liquid refrigerant. Subsequently, it is introduced into the refrigerant heat absorption cylinder 9 in the warm water tank 2 through the refrigerant inlet pipe 5 and the circulating refrigerant connector 4.

[0027] It is worth noting that the upper part of the refrigerant heat absorption cylinder 9 is connected and fixed with a refrigerant outlet pipe 15, and the lower part of the refrigerant heat absorption cylinder 9 is connected and fixed with a refrigerant inlet pipe 5.

[0028] It is worth noting that bearings 13 are embedded and fixed at the center of both ends of the refrigerant heat absorption cylinder 9. A rotating shaft 10 is rotatably connected inside the refrigerant heat absorption cylinder 9. Both ends of the rotating shaft 10 pass through the bearings 13. Refrigerant stirring blades 11 are fixed on the side surface of the rotating shaft 10. When the drive motor 7 is started, it drives the rotating shaft 10 to rotate. The refrigerant stirring blades 11 on it stir the liquid refrigerant in the refrigerant heat absorption cylinder 9, breaking the uneven heat absorption caused by the position difference of the refrigerant, promoting the overall circulation of the refrigerant, and ensuring uniform heat absorption.

[0029] It is worth noting that a warm water stirring blade 12 is fixedly fitted onto one end of the rotating shaft 10 that protrudes from the bearing 13; the warm water stirring blade 12 stirs the warm water in the warm water tank 2, enhances the fluidity of the warm water, ensures that the high-temperature warm water is in continuous contact with the outer wall of the refrigerant heat absorption cylinder 9, and stabilizes the heat transfer.

[0030] It is worth noting that a sealing seat 14 is fixed to one end face of the refrigerant heat absorption cylinder 9, and a drive motor 7 is fixed to one end face of the sealing seat 14. The output shaft of the drive motor 7 is fixed to one end of the rotating shaft 10 that passes through the sealing seat 14.

[0031] It is worth noting that a liquid supply pump 6 is fixed to one side of the surface of the warm water tank 2. A refrigerant inlet pipe 5 is installed at the front end of the liquid supply pump 6. A circulating refrigerant connector 4 is fixed to one end of the refrigerant inlet pipe 5. The upper end of the refrigerant outlet pipe 15 is connected to the evaporator in the chiller body 1. A return channel is provided between the circulating refrigerant connector 4 and the condenser in the chiller body 1. A warm water inlet pipe 3 is fixed to one end of the warm water tank 2. After absorbing the heat of the warm water in the warm water tank 2, the liquid refrigerant evaporates into a gaseous state. The low-pressure gaseous refrigerant is drawn into the compressor and compressed into a high-temperature and high-pressure gaseous refrigerant through mechanical work. The high-temperature and high-pressure gaseous refrigerant enters the condenser, exchanges heat with the cooling medium, releases heat, and condenses into a high-pressure liquid state. It is then depressurized again through the expansion valve to a low-temperature and low-pressure liquid refrigerant, and flows back into the refrigerant heat absorption cylinder 9 of the warm water tank 2 through the return channel, starting a new cycle and continuously cooling the air conditioning cooling water in the clean room.

[0032] This solution involves the following working process: Before use, the cooling water of the cleanroom's air conditioning equipment heats up after absorbing heat. The heated cooling water is then fed into the warm water tank 2 inside the chiller unit 1. While the chiller unit 1 is operating, the high-pressure liquid refrigerant flowing from the condenser passes through an expansion valve. The valve, through throttling, reduces the pressure to a low-temperature, low-pressure liquid refrigerant. This liquid refrigerant is then fed into the warm water tank 2 and stored in the refrigerant heat absorption cylinder 9. While residing in the refrigerant heat absorption cylinder 9, the liquid refrigerant absorbs heat from the warm water in the warm water tank 2. During this heat absorption process... The rotating shaft 10 rotates under the drive of the drive motor 7. Since the refrigerant stirring blade 11 is fixed on the rotating shaft 10 inside the refrigerant heat absorption cylinder 9, while the warm water stirring blade 12 is fixed on the rotating shaft 10 outside the refrigerant heat absorption cylinder 9, the refrigerant stirring blade 11 can stir the liquid refrigerant, improve the situation of local heat absorption difference caused by the high temperature at the refrigerant heat absorption cylinder 9 and the low temperature at the center. Stirring can make the refrigerant circulate as a whole, so that all refrigerant molecules can contact the high temperature cylinder wall evenly, and avoid the waste of local refrigerant not absorbing enough heat.

[0033] During the process of stirring the warm water in the warm water tank 2 with the stirring blades 12, the stirring method can improve its fluidity and prevent the warm water near the outer wall of the refrigerant heat absorption cylinder 9 from cooling down due to heat release. This allows the high-temperature warm water to remain close to the cylinder wall, ensuring that the heat from the heat source in the warm water tank 2 is stably transferred to the cylinder wall.

[0034] After absorbing heat from the warm water, the refrigerant evaporates into a gaseous state. The low-pressure gaseous refrigerant produced by the evaporator is drawn into the compressor, which compresses it into a high-temperature, high-pressure gaseous refrigerant through mechanical work. The high-temperature, high-pressure gaseous refrigerant enters the condenser and exchanges heat with the cooling medium. After releasing heat, the refrigerant condenses into a high-pressure liquid, and the heat is carried away by the cooling medium and discharged into the external environment. The high-pressure liquid refrigerant flowing out of the condenser passes through the expansion valve, which reduces its pressure to a low-temperature, low-pressure liquid refrigerant through throttling (pressure drops sharply, and temperature drops simultaneously). The refrigerant then flows back into the warm water tank 2 to start the next cycle.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Although embodiments of this utility model have been shown and described, this does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
