[0002] With the booming development of manufacturing enterprises, there are more and more types of equipment such as R & D tools and instruments in laboratories, scientific research institutions, manufacturing enterprises, etc. Since most of the equipment are heat-generating equipment, some of these equipment have high requirements for temperature control. If the temperature exceeds the high-temperature limit point, an alarm or alarm protection will occur. The life of equipment materials, components, etc. of individual equipment will be affected by high temperature. Some equipment with attached sensors or image acquisition devices will be affected by high temperature, and the data acquisition and image acquisition effect rates will be affected. At present, most of the equipment purchased is professional water-cooled circulation equipment. Since this type of equipment has a built-in compressor, the water-cooling effect is good, but the energy consumption is high. Especially when used in some small equipment, there is a phenomenon of using a big horse to pull a small cart, and there is too much useless power. Some equipment, although not equipped with a water chiller, has to stop waiting when the temperature is high during use and start again after the temperature drops. In view of this, there is a great demand for inventing this type of equipment, and it can also meet the needs of some small cooling equipment. Content of the Utility Model

[0016] The present utility model will be further described below in conjunction with the drawings and specific embodiments:

[0017] As Figure 1 shown, an environmentally friendly automatic water replenishing water circulation cooling device for laboratories includes a cylindrical closed cooling box 1, and the cooling box 1 is placed vertically.

[0018] The bottom of the inner cavity of the cooling box 1 is a water tank 13 for holding cooling water. A water pipe joint 7 penetrating to the outside of the cooling box 1 is connected to the upper edge of the water tank 13. The water pipe joint 7 is used to inject water into the water tank 13 or the water in the water tank 13 overflows outward. A water pump 8 is arranged in the water tank 13. The outlet of the water pump 8 is connected with a diversion pipe, and the diversion pipe extends upward in the cooling box 1 to the upper part of the cooling box 1. A horizontal corrugated plate 2 is fixed below the diversion pipe. The corrugated plate 2 is fixed in the inner cavity of the cooling box 1. The corrugated plate 2 is used to disperse the water discharged from the diversion pipe, and the dispersed water falls into the water tank 13. A circulation pump 12 is also arranged in the water tank 13. The water outlet pipe of the circulation pump 12 is connected to the water inlet of the equipment 14 to be cooled, and the water outlet of the equipment 14 to be cooled returns to the water tank 13 through a water pipe.

[0019] An air inlet is arranged in the middle of the cooling box 1, and an air outlet is arranged on the other side of the cooling box 1 opposite to the air inlet; an intake fan 4 is arranged on the air inlet, and an exhaust fan 3 is arranged on the air outlet. An inverted water replenishing bottle 5 is also fixed in the cooling box 1, and the mouth of the water replenishing bottle 5 is submerged below the water surface of the water tank 13; when the water level in the water tank 13 drops and the mouth of the water replenishing bottle 5 is exposed above the water surface, the water in the water replenishing bottle 5 flows into the water tank 13.

[0020] A filter screen 9 is also arranged at the inlet of the water pump 8. The top of the cooling box 1 is connected with a cover plate for maintenance, and a maintenance port for replenishing water to the water replenishing bottle 5 is arranged on the side surface of the cooling box 1.

[0021] The working principle of the present utility model is as follows:

[0022] After the water pump 8 is started, the water pump 8 pumps the water in the water tank 13 to above the corrugated plate 2 at the top of the device. The water naturally flows down through multiple paths and water holes designed in the corrugated plate 2, forming multiple groups of "raindrops" or water curtains in the cooling box 1 of the device; at the same time, two small fans, an exhaust fan and an exhaust fan 3, are installed on the low-end side wall of the cooling box 1, and a circulating air is formed in the cooling box 1 through the fans. When the circulating air and the water curtain in the box body are convected with each other, the effect of cooling the water temperature in the box body will be achieved; the water in the water tank 13 is brought into the equipment 14 to be cooled through the built-in circulating pump 12 to achieve the cooling purpose; to solve the possibility of insufficient water in the water tank 13 to protect the pump body and low cooling effect due to less water, the device also increases a water replenishing bottle 5. When the water level drops due to the cooling process, the water can be automatically compensated through the water replenishing bottle 5 to meet the requirements of the water system water volume.

[0023] The corrugated plate 2 is in a groove shape, and the bottom of each groove is designed with small holes of 2 millimeters, and the hole spacing is 2 millimeters. After the water pump pumps water to the corrugated plate 2, the water in each groove of the corrugated plate 2 flows down through the small holes, forming raindrop-shaped water beads and falling into the water tank 13, and reciprocating.
