Including inner and outer tubes, flowing has refrigerant gas in the closing space that inner and outer pipes are formed.
Pass through above-mentioned technical proposal：After cooled object is conveyed into pressure cooling zone, due to hot-air upwards, therefore its
The hot gas itself given out can be poured in constantly in air outlet, after air outlet is entered, during by cooling tube, due to cooling tube
The closing space that is formed of inner and outer pipes in have refrigerant gas, therefore the cooling gas can carry out heat to the hot gas in cooling tube
Exchange, after hot gas cooling, behind under the promotion of hot gas, pressure can be discharged into again by air admission hole through overcooled gas
In cooling zone, ventilation cooling treatment is carried out to cooled object.Wherein due to the system in the cooling tube described in the technical program
Cold air is flowing, therefore the gas in processing procedure in cooling tube constantly carries out constantly changing just can guarantee that preferably
Heat exchange is carried out to hot gas, and is cooled to.In the technical program, hot gas is not to be expelled directly out pollution air and influence temperature
Degree, but it is realized from radiating by the method for cycle alternation, the technical program technology to be reached effect is realized well
Really.
The technical program is further arranged to：Air admission hole and venthole, air admission hole are offered on the outer tube of the cooling tube
It is connected with the delivery outlet of refrigeration plant, outlet nose end is connected with radiating tube.
Pass through above-mentioned technical proposal：Cooling gas in cooling tube can be entered by air admission hole, and be arranged by venthole
Go out, after the exit, radiating can also be carried out to it by radiating tube and be then exhausted from, realize that flowing substitutes in refrigerant gas, reach preferably
Radiating effect while, also it is secondary reduce discharge gas temperature, further optimize technique effect of the present utility model.
The technical program is further arranged to：Ventilating fan is all connected with the position of the air inlet and air outlet.
Pass through above-mentioned technical proposal：Only the physical characteristic declined by the hot-air rising cold air of gas itself is very
Difficulty allow gas according to equipment in itself the need for circulated, and by the row for being separately positioned on air inlet and air outlet
Fan, then can be very good twitch gas and flowed according to default direction.Further optimize the technical solution of the utility model.
The technical program is further arranged to：The radiating tube is folded between two coldplates, and in three-back-shaped bending.
Pass through above-mentioned technical proposal：Radiating tube is in three-back-shaped bending, can extend its length that radiates in certain space, plus
Strong radiating, and radiating tube is folded between coldplate, then it can realize the technique effect of gas in quick cooling radiating tube.
