Portion's directly contact, in the way of heat transfer, the temperature by reducing pallet reaches the purpose to ingot blank cooling, obtains mechanicalness
The enough ingot blanks of energy；
5) dividing plate is set in the heat-absorbing structure absorbed heat in tray bottom it is ensured that the bottom baffles in pallet form heat conduction Jie
The loop that mass flow is moved, heat-conducting medium flows in the presence of circulation power pump from bottom to top, when the lower end flowing to dividing plate, every
From the center of heat conduction chamber to perimeter in the presence of plate, and the flowing with heat-conducting medium, its temperature gradually rises, that is,
Higher in the temperature of the position heat-conducting medium of the wall the closer to heat conduction chamber for the top of heat conduction chamber, improve heat-conducting medium and pallet
The heat absorption efficiency of bottom, improves the cooling speed of the ingot blank being deposited on pallet top by the rate of cooling improving tray bottom
Degree, thus obtain performance to meet the ingot blank requiring；Setting heat-conducting medium inner tube, one end of heat-conducting medium inner tube and heat-conducting medium go out
Mouth connection, the other end of heat-conducting medium inner tube is communicated to the top of heat conduction chamber and the position of the wall near heat conduction chamber, temperature
Spending high heat-conducting medium derives heat conduction chamber through heat-conducting medium inner tube, that is, heat-conducting medium inner tube by heat-conducting medium high for temperature with
The low heat-conducting medium of temperature distinguishes, it is to avoid temperature high heat-conducting medium is heated to also not entering with tray bottom completely when deriving
The low heat-conducting medium of the temperature of row heat exchange, beneficial to the heat exchanger effectiveness improving this heat-absorbing structure, improves to tray bottom
Rate of cooling；
6) described heat-conducting medium import is less than described heat-conducting medium in the position of described heat conduction chamber and exports in described heat conduction
The position of chamber, the low heat-conducting medium of temperature enters from the bottom of heat conduction chamber, overcomes gravity in the presence of circulation power pump
Flow up, then contact with the bottom of ingot blank or pallet, due to self gravitation, heat conduction will be overcome when heat-conducting medium flows up
The medium rate of climb is slow it is ensured that heat-conducting medium and ingot blank or pallet sufficient time of contact are it is ensured that the higher heat of heat-absorbing structure is handed over
Change efficiency, so as to improving the cooling rate of ingot blank, obtain the ingot blank of superior performance.

Quickly cooled down, thus obtaining the ingot blank 5 of excellent performance.Another part heat in aerochamber 10 flows out through gas outlet 9.
Separately, in heat exchanging process, setting dust-proof mechanism plays and does not affect to prevent dust to be attached to while reaction-injection moulding
The surface of ingot blank 5, with the decline of shifting axle 8, compression spring 13 promote slide plate 12 cover plate 14 upper table towards through hole axle
The heart slides, so as to reducing the upper end exposed area in the horizontal direction of ingot blank 5, thus reducing aerochamber 10 inner cover plate 14 top
Dust is attached to the possibility on ingot blank 5, is avoided as much as ingot blank 5 and is mingled with impurity it is ensured that forming the performance of each several part of ingot blank 5
Uniformity it is ensured that the stability of the physics of ingot blank 5, chemical property；
By arranging locating piece 11 and locating piece 11 locking device, locating piece 11 apart from the axle center scalable of through hole, and
By locating piece 11 locking device, described locating piece 11 is locked on a certain sliding position, the upper end making ingot blank 5 is in level side
To exposed area be adjusted to suitable size, the size of this area is deposited on the premise of ingot blank 5 to the greatest extent with not affecting metal fluid column 2
Possible is little.
