Description

Technical Field

[0001] This utility model relates to the field of refrigeration technology, and in particular to an energy-saving refrigeration unit. Background Technology

[0002] A refrigeration unit is a mechanical device that uses a compressor to change the pressure of a refrigerant gas to achieve low-temperature refrigeration. It mainly consists of four parts connected in series: a compressor, a condenser, an evaporator, and an expansion valve. An appropriate amount of refrigerant is charged into the unit, and electrical control adjusts the compressor's operation according to environmental requirements to achieve refrigeration and heat transfer. Refrigeration units are widely used in various fields such as industry, commerce, and construction.

[0003] However, in existing refrigeration units, the refrigerant, which condenses into liquid at the center during the cooling and heat exchange process, is not conducive to rapid heat dissipation. Heat dissipation proceeds gradually from the liquid surface of the refrigerant towards the inner center, resulting in low heat exchange efficiency and significant time and energy consumption. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose an energy-saving refrigeration unit to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides an energy-saving refrigeration unit, including a refrigeration unit body that uses refrigerant for refrigeration. A condenser for heat exchange with liquid refrigerant is installed inside the refrigeration unit. A cooling water tank for storing cold water is attached to one side of the condenser. A heat-conducting fin is inserted into the condenser inside the cooling water tank. A water guide channel for guiding cold water is formed inside the heat-conducting fin. A water pump unit for power supply is fixedly installed at the bottom of the water guide channel. A water outlet for spraying water is formed at the top of the water guide channel. The water pump unit is signal-connected to a main control unit for automatic control. The main control unit is signal-connected to a heat-conducting extension sleeve for telescopic adjustment. A limiting support plate is fixedly installed at the top of the cooling water tank for support. A level gauge for detecting cold water is fixedly installed in the middle of the limiting support plate.

[0006] Preferably, in any of the above embodiments, the cooling water tank is fixedly installed on the top of the chiller body, the top of the chiller body has a heat dissipation hole that communicates with the cooling water tank, the top of the heat dissipation hole is fitted with a heat dissipation protective sleeve for protection, and the condenser has a heat exchange chamber for heat exchange inside.

[0007] The above technical solution involves fixing the cooling water tank to the top of the chiller body, connecting the heat dissipation holes to the cooling water tank, and using a heat dissipation protective sleeve at the top of the heat dissipation holes to prevent external debris from entering. The heat exchange chamber inside the condenser is used for refrigerant heat exchange, and the cold water stored in the cooling water tank cools the refrigerant inside the condenser. This ensures that the cooling water tank and the chiller body are tightly integrated, shortening the heat transfer path, improving heat exchange efficiency, reducing energy loss, and ensuring the efficient and stable operation of the chiller body.

[0008] Preferably, in any of the above embodiments, the heat-conducting sheet penetrates the cooling water tank and is inserted into the interior of the condenser. One end of the heat-conducting sheet is provided with a limiting plate to limit its movement. The limiting plate is in contact with the inner wall of the cooling water tank. The interior of the heat-conducting sheet is provided with a base plate to support the heat-conducting extension sleeve.

[0009] The above technical solution involves inserting a heat-conducting fin through the cooling water tank into the condenser. A limiting plate at one end of the fin fits against the inner wall of the cooling water tank to prevent excessive insertion and ensure the tank's airtightness. The substrate inside the heat-conducting fin provides support for the heat-conducting extension sleeve. The heat-conducting fin can transfer the heat of the refrigerant in the condenser to the cold water in the cooling water tank, increasing the heat exchange area, improving heat exchange efficiency, effectively reducing the refrigerant temperature, and reducing the obstruction to heat transfer within the refrigerant, resulting in a more uniform cooling effect.

[0010] Preferably, the bottom of the water guide channel is provided with a water inlet hole that communicates with the water pump group. Both the water inlet hole and the water outlet hole are opened inside the heat-conducting plate, and a dispersion plate is provided at one end of the water outlet hole.

[0011] The above technical solution is adopted: the water inlet at the bottom of the water guide channel is connected to the water pump group, the water guide channel guides the cold water to flow in the heat conduction plate, the cold water absorbs the heat of the refrigerant during the flow, and when it is sprayed out from the water outlet, the dispersion plate increases the contact area between the cold water and the air, accelerates the heat dissipation of the cold water, further improves the heat exchange efficiency, and ensures the stability and continuity of the cooling of the refrigerant.

[0012] Preferably, in any of the above schemes, the water pump assembly includes a water pump connected to the main control unit and an inlet pipe for conveying cold water. One end of the inlet pipe is provided with a guide head that communicates with the water inlet. The inlet pipe is fixedly installed at the bottom of the cooling water tank, and a water pump is fixedly installed at one end of the inlet pipe.

[0013] The above technical solution is adopted: the water pump is controlled by the main control unit to transport the cold water in the cooling water tank to the water guide channel, providing power for the cold water circulation, so that the cold water flows continuously in the heat conduction plate, continuously carrying away the heat of the refrigerant. At the same time, the flowing cold water is sprayed out from the water outlet to exchange heat with the air, enhance the heat dissipation effect, and ensure stable heat exchange.

[0014] Preferably, in any of the above embodiments, the thermally conductive extension sleeve includes an electric telescopic rod connected to the main control unit and a movable thermally conductive sleeve. The electric telescopic rod is fixedly installed at both ends of the substrate, and a thermally conductive sleeve that moves inside the thermally conductive sheet is fixedly installed at one end of the electric telescopic rod.

[0015] The above technical solution involves the main control unit controlling the extension and retraction of the electric telescopic rod, which moves the heat-conducting sleeve within the heat-conducting plate, adjusting the area of ​​the heat-conducting plate involved in heat exchange. When it is necessary to enhance the heat exchange effect, the electric telescopic rod extends, causing the heat-conducting sleeve to expand and increasing the contact area between the heat-conducting plate and the refrigerant. Conversely, it contracts, thus achieving flexible control of the heat exchange process and improving energy utilization efficiency.

[0016] Preferably, in any of the above embodiments, the limiting support plate is located below the water outlet, the top of the limiting support plate is configured with an arc-shaped structure, and the level gauge is located inside the cooling water tank.

[0017] The above technical solution is adopted: the arc-shaped structure at the top of the limiting support plate can guide the sprayed cold water, so that the cold water is more evenly distributed in the cooling water tank, avoiding local water temperature overheating and improving the heat dissipation efficiency of the cold water in the cooling water tank. The level gauge is installed inside the cooling water tank to monitor the cold water level in real time. When the level is too low, it can promptly remind the operator to add cold water to ensure that there is enough cold water in the cooling water tank to participate in heat exchange and ensure the stable operation of the refrigeration unit.

[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0019] 1. A through-type heat-conducting fin is installed inside the condenser of the refrigeration unit, and a water pump unit is used to connect the heat-conducting fin to the cooling water tank. The water pump unit can be used to introduce cooling water into the interior of the heat-conducting fin, and the heat exchange between the inside and outside of the heat-conducting fin can achieve cooling of the refrigerant inside the condenser. At the same time, the heat-conducting fin can be inserted into the interior of the refrigerant, so as to cool the refrigerant more comprehensively, increase the contact area with the refrigerant, reduce the influence of the refrigerant's position on heat exchange, improve the efficiency of refrigerant heat exchange, and reduce the energy consumption caused by the length of heat exchange time.

[0020] 2. The water pump set provides a certain power to the cold water for heat exchange, so that the cold water flows in the water guide groove inside the heat conduction plate and is sprayed out from the water outlet. The heat in the water is dissipated by the contact between the sprayed water and the air, which increases the heat dissipation efficiency of the heat exchange water and helps to ensure the stability of heat exchange.

[0033] Preferably, in any of the above embodiments, the heat-conducting plate 4 penetrates the cooling water tank 3 and is inserted into the interior of the condenser 2.

[0034] The above technical solution is adopted: the heat-conducting plate 4 penetrates the cooling water tank 3 and is inserted into the condenser 2. The limiting plate at one end of the heat-conducting plate 4 is attached to the inner wall of the cooling water tank 3 to prevent the heat-conducting plate 4 from being over-inserted and to ensure the sealing of the cooling water tank 3.

One end of the inlet pipe 62 is provided with a guide head that communicates with the water inlet hole. The inlet pipe 62 is fixedly installed at the bottom of the cooling water tank 3, and the water pump 61 is fixedly installed at one end of the inlet pipe 62.

[0038] The above technical solution is adopted: the water pump 61 is controlled by the main control unit to transport the cold water in the cooling water tank 3 to the water guide channel 5, providing power for the cold water circulation, so that the cold water flows continuously in the heat conduction plate 4, continuously carrying away the heat of the refrigerant.

The water pump 61 pumps the cold water in the cooling water tank 3 into the water inlet hole at the bottom of the water guide channel 5 through the inlet pipe 62. The cold water flows in the water guide channel 5, absorbing the heat of the refrigerant in the condenser 2 transferred by the heat conduction plate 4. Then it is sprayed out from the water outlet hole 7. The dispersion plate at one end of the water outlet hole 7 makes the cold water evenly dispersed and fully contact the air to dissipate heat. Then it falls back into the cooling water tank 3, completing the cold water circulation and heat dissipation process. The liquid level gauge 10 monitors the cold water level in the cooling water tank 3 in real time. If the liquid level is abnormal, it is convenient to replenish the cold water in time.
