Detailed Description

Referring to fig. 1-5, the present invention provides the following technical solutions: including protection casing 1 and installing at the inside compressor body 4 of protection casing 1, compressor body 4 inclines fixed connection in the inside of protection casing 1 through two support frames 5, the outside cover of compressor body 4 is equipped with water spray ring 3, the annular equidistance distribution of a plurality of the inner wall fixedly connected with of water spray ring 3 is used for the water shower nozzle 31 to the cooling of compressor body 4, 1 side fixedly connected with recirculated cooling water tank 2 of protection casing, recirculated cooling water tank 2 is linked together through water pipe 22 between water spray ring 3.

In this embodiment: compressor body 4 is in the inside of protection casing 1 through the fixed connection of support frame 5 slope, protection casing 1 can prevent that water from spattering to the outside condition that causes environmental pollution when spraying, and the axis of spray ring 3 and the collineation of compressor body 4 axis, recirculated cooling water tank 2 is carried liquid to spray ring 3 inside through water supply pipe 22, spray ring 3 inner wall fixed connection's water shower nozzle 31 sprays liquid on compressor body 4 surface this moment, receive the injection influence this moment, the quick lateral wall below to the left side around recirculated cooling water tank 2 of liquid flows, and then when making liquid and compressor body 4 surface fully contact, when reacing the minimum, drop downwards, effectual improvement heat transfer speed, simultaneously because coolant liquid area of contact increases effectual improvement heat conversion efficiency.

The tops of four sides of the periphery of the protective cover 1 are fixedly connected with ventilation windows 11 for ventilation; because steam can flow to the top, and the transom 11 can form the air convection at the top of protection casing 1 this moment, and then quick with the inside hot-air of protection casing 1 and outside air contact heat transfer, and then guarantee that the inside steam of protection casing 1 can give off fast, further improvement heat exchange efficiency.

The side surfaces of the protective cover 1 and the circulating cooling water tank 2 are communicated with each other through a water return pipe 21, the bottom surface of the inner wall of the protective cover 1 is fixedly connected with a guide slope surface 12, and the guide slope surface 12 inclines towards the bottom end of the water return pipe 21; when the liquid drops, the liquid will be influenced by gravity and flow from the high point to the low point along the guide slope 12, so that the liquid flows to the return pipe 21 and is pumped to the inside of the tank body by the water pump inside the circulation cooling water tank 2 for cooling.

The water supply pipe 22 extends from the top of the shield 1 to the inside of the shield 1; because the top of protection casing 1 is solid structure, and the water pipe 22 extends to inside through the top, and solid structure is fixed more stably with water pipe 22.
