A low temperature coolant circulating pump

Abstract

The application relates to a low-temperature coolant circulation pump, which includes a protective box, a compressor is fixed on one side of the protective box, a condenser is fixed on one end of the protective box perpendicular to the compressor, and a solid is installed between the compressor and the condenser. The refrigerant vapor compressed by the compressor is transported to the inner guide pipe of the condenser, the condenser includes a water tank, and the heat dissipation mechanism is arranged on the water inlet pipe; the heat dissipation mechanism includes four heat dissipation components fixed in the protective box , the water in the water inlet pipe flows back into the condenser after being dissipated successively by the four heat dissipation components; A blower is installed, and a drive shaft is connected to the vertical rotation in the return groove. The drive shaft is evenly fixed with a plurality of fan blades along its circumference. The wall is fixed with a plurality of heat conducting plates. This application has a better cooling effect on the cooling water cooling effect.

Description

technical field [0001] The present application relates to the field of circulating pumps, in particular to a low-temperature coolant circulating pump. Background technique [0002] The low-temperature coolant circulation pump is a low-temperature liquid circulation equipment that adopts mechanical refrigeration, and has the function of providing low-temperature liquid and low-temperature water bath. Combined with rotary evaporator, vacuum freeze-drying oven, circulating water vacuum pump, magnetic stirrer and other instruments, it can carry out multifunctional chemical reaction operations and drug storage at low temperature. [0003] The low-temperature coolant circulation pump includes a compressor and a condenser. The compressor sends the refrigerated steam to the condenser, where it exchanges heat with water. The cold steam cools the water, and the cooled water is pumped out to the user's cooling room. On the equipment, after use, it is returned to the condenser for circ...

Problems solved by technology

[0003] The low-temperature coolant circulation pump includes a compressor and a condenser. The compressor sends the refrigerated steam to the condenser, where it exchanges heat with water. The cold steam cools the water, and the cooled water is pumped out to the user's cooling room. On the equipment, after use, it is returned to the condenser for circulation and cooling. However, after the cooling water cools the equipment that needs to be cooled, it will take away the heat and cause its own temperature to rise. When it is returned to the condenser for cooling and cooling, due to compression The cooling heat of the cold steam output by the machine remains unchanged, which leads to the reduction of the cooling effect of the circulating water in the condensation pipe
