Description

Technical Field

[0001] The utility model relates to the technical field of water-cooled radiators, in particular to a high-efficiency cooling device. Background Art

[0002] At present, many project sites have low-temperature water, such as groundwater in the underground environment of coal mines, condensate generated in the mineral processing process of mineral processing plants, circulating cooling water in the petrochemical industry, etc. However, the water quality at these sites is generally very poor. If it is used directly to cool industrial equipment, it will clog or even corrode the cooling pipes of the equipment after a long period of use, causing equipment damage or over-temperature shutdown.

[0003] Nowadays, industrial high-power equipment usually adopts water cooling, and the circulating water used is mostly provided separately. In addition, there is no good way to use low-temperature water when there is low-temperature water on site. This type of water cooling device mainly includes: water pump, radiator, water tank, shell, valve and other auxiliary parts. Figure 1 As shown, its working principle is that the water outlet of the cooled equipment is connected to the return water outlet of the water cooling device, and the circulating water reaches the radiator after passing through various valves, sensors and filters on the return water pipeline of the water cooling device. The circulating water cooled by the air flow enters the water tank, and then the circulating water is pumped out by a water pump. After passing through various valves and sensors on the water outlet pipeline of the water cooling device, it enters the water inlet of the cooled equipment from the water outlet of the water cooling device, thereby realizing water cooling of the equipment. The patent number is ZL201821093713.7, "An intelligent water cooling device for permanent magnet motors", in which the heat exchanger is an air-cooled heat exchanger; the patent number is ZL201420172061.1, "Cooling device for explosion-proof inverter for mining", in which the air-water exchanger includes a cooling fan; the patent number is ZL201921671795.3, "A Fengshui cooling device with a pre-filter structure", in which a ventilation mesh plate is provided at the heat exchanger; the patent number is ZL201720235894.1, "A Fengshui integrated cooling water circulation device for mining explosion-proof and intrinsically safe", in which one end of the water pump 4 is connected to a Fengshui exchange radiator.

[0004] In summary, the prior art water cooling devices all use wind-water exchange to cool the circulating water, so they are precisely wind-water cooling devices. Since wind cooling requires ventilation, the frame shell of the wind-water cooling device needs to be set as a non-sealed structure with ventilation holes, resulting in dust, particles and other impurities easily entering the cooling device box in harsh environments, thereby damaging key components such as water pumps and radiators, and cannot be quickly replaced.

[0005] Disadvantages of existing Feng Shui cooling devices: 1. There is low-temperature water on site, but the water quality is poor and cannot directly cool industrial equipment; 2. Feng Shui cooling devices, due to their non-sealed structure, cause dust, particles and other impurities to easily enter the cooling device box, thereby damaging key components such as water pumps and radiators. Summary of the invention

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a high-efficiency cooling device, comprising a closed outer shell, a water tank connected to the outer shell, a radiator placed inside the water tank, and an internal water circulation device; the radiator inside the water tank is composed of a bent water channel pipeline and heat sinks; the internal water circulation device includes a water pump, a filter, a valve, a flow meter, a thermometer, and a pressure gauge.

[0007] Furthermore, the filter includes filter one and filter two, and external cooling water enters the curved water channel of the radiator through filter one, and the circulating water flowing into the return water port of the cooling device enters the water tank after passing through filter two.

[0008] Furthermore, the curved water channel of the radiator can be S-shaped, Z-shaped, U-shaped, W-shaped, etc., and arranged in multiple layers, and the heat sink is arranged in multiple pieces and fixed on the curved water channel at equal distances.

[0009] Furthermore, the radiator is provided with a lifting hook or a lifting ring for facilitating overall replacement.

[0010] Furthermore, the bottom of the water tank and the meandering water channel of the radiator are both provided with drainage outlets to facilitate the regular discharge of impurities and waste water.

[0011] The utility model has the following beneficial effects:

[0012] (1) Energy saving and environmental protection, reasonable recycling of cooling water on the project site, good heat dissipation effect.

[0013] (2) Due to the use of high-efficiency cooling, the cooling device box has good sealing performance, which prevents dust, particles and other impurities from entering the box, making it difficult to damage key components and extending the service life of the cooling device.

[0014] (3) Compared with the air-water exchange type, the water-to-water exchange type eliminates the need for a cooling fan and does not require consideration of air ducts. The radiator is placed inside the water tank, making the cooling device more compact, smaller in size, and lighter in weight. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the examples of the utility model to describe the technical solutions in the examples of the utility model in detail. The examples described are only part of the examples of the utility model, not all of them. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The following is a further description of the present invention in conjunction with the accompanying drawings;

[0024] like Figure 2-5 As shown, a high-efficiency cooling device includes a closed shell 1, a water tank 2 connected to the shell, a radiator 3 placed inside the water tank, and an internal water circulation device; the radiator 3 inside the water tank 2 is composed of a bent water channel pipe 32 and a heat sink 31; the internal water circulation device includes a water pump 45, a filter 1 41, a filter 2 42, various valves, a flow meter, a thermometer, a pressure gauge, etc.

[0025] The working principle of the high-efficiency cooling device is to first inject clean circulating water into the water tank 2 to ensure that it can completely cover the curved water channel pipe 32 and the heat sink 31 of the radiator 3. After starting the water pump 45, the internal circulation starts, and the water pump 45 pumps out the circulating water, passes through various valves and sensors on the water outlet pipe of the high-efficiency cooling device, and then enters the cooled device from the cooling device outlet 44. After the circulating water takes away the residual heat of the cooled device, it flows out from the water outlet of the cooled device and enters the cooling device return water port 43 and returns to the water tank 2 after being filtered by various valves, sensors and filter 2 42. At the same time, the external cooling water enters from the radiator water inlet 35, flows through the filter 1 41 and the curved water channel pipe 32 in sequence, and then flows out from the radiator outlet 34. Because the bent water channel 32 and the heat sink 31 are immersed in the circulating water, the contact area is greatly increased, and the circulating water in the water tank 2 is cooled by heat conduction. The cooled circulating water enters the cooled equipment again through the water pump 45, thus forming a reciprocating cycle to achieve effective heat dissipation of the cooled equipment.

[0026] In the embodiment of the utility model, the curved water channel pipe 32 of the radiator 3 can be S-shaped, Z-shaped, U-shaped, W-shaped, etc., and can be arranged in multiple layers. The heat sink 31 is arranged in multiple pieces and fixed on the curved water channel pipe 32 at equal intervals.

[0027] In the embodiment of the utility model, the bottom of the water tank 2 and the bent water channel 32 of the radiator 3 are both provided with a water tank drain port 21 and a radiator drain port 36, so as to facilitate the regular discharge of impurities and waste water.

[0028] In the embodiment of the utility model, the closed housing 1 refers to a rack housing of a high-efficiency cooling device designed as a whole plate, without considering a non-sealed structure with ventilation holes or air ducts due to ventilation requirements.

[0029] In the embodiment of the utility model, the radiator 3 is provided with a lifting and mounting member, including a hook 33 or a lifting ring, a nut, a pad, and a bottom plate. The rod of the hook 33 is a screw rod, which cooperates with the threaded hole on the bottom plate, and then the nut is tightened to be pressed together with the radiator 3. There is a hole on the top plate of the radiator 3 for the hook 33 to pass through. The radiator 3 includes two fixing methods: ceiling and bottom seat. The ceiling is fixed by the top plate and the threaded hole on the box body. The bottom seat is fixed by directly dropping the bottom plate on the bottom of the water tank 2 and then fixing it. Both methods can quickly take out the radiator 3 as a whole when it needs to be cleaned or replaced, which is convenient for replacement.
