Abstract
The utility model provides a sandwich heat sink which comprises an inner cylinder, an outer cylinder, barrier strips, separation strips, liquid inlet main pipes and liquid outlet main pipes, wherein the inner cylinder and the outer cylinder are hollow steel cylinders. Separation strips are welded on the outer peripheral direction of the inner cylinder. The separation strips are radially arranged in the radial direction on the outer circle of the inner cylinder. The surface wherein the barrier strips are welded with the inner cylinder is provided with uniformly arranged transverse arc grooves. The inner cylinder is integrally sleeved in the outer cylinder. A clearance between a left end face and a ring end face of the inner cylinder and the outer cylinder is welded through the barrier strips. A liquid outlet is provided above the outer cylinder and is connected with the liquid outlet main pipe. A liquid inlet is provided at the lower part and is connected with the liquid inlet main pipe. For ensuring that the temperature uniformity of the heat sink is in a range of +/- 1 DEG C, Three to four groups of parallel liquid inlet main pipes and liquid outlet main pipes are adopted. The appearance of the structure of the sandwich heat sink is smooth. The vacuum air exhaust is facilitated. The heat exchange efficiency can be increased for three times compared with that of the common heat sink. The temperature uniformity is increased for 50%. The experiment reliability is increased while the time of environment analog experiment is shortened.
Description
Technical field
It is heat sink that the utility model relates to a kind of sandwich-type that is used for space-environment facility.Belong to the space-environment facility field.
Background technology
Space-environment facility is the equipment of virtual space vacuum and high and low temperature environment, heat sink is the critical piece of this kind equipment, pass through radiant heat exchange, for the equipment test space provides required temperature environment, in order to reach this purpose, must control heat sink temperature, the control heat sink temperature is to force mobilely in heat sink runner by refrigerant, realizes with heat sink heat exchange.
Present various heat sink employing coiled or plshy bone open structure, its pipe intermediate flow is crossed refrigerant, these two kinds of structures are all filled between pipeline and cylindrical shell and are contacted bad drawback, the intensification of cylindrical shell and cooling are just very slow, to not holding still stage, just must all weld pipeline and cylindrical shell for this reason, do first workload very big second like this and can stay dead space, this does not allow vacuum, so on technology, also must take measures to prevent the generation of dead space, novel sandwich-type is heat sink to be to design for realizing 100% heat exchange area according to the problem that present coiled or plshy bone open heat sink structure exist, thereby improve 3 times of heat exchanger effectiveness, alcohol or conduction oil can be suitable for, especially to wide journey conduction oil, its superiority is more arranged, and it can not be used in heat sink going up and lay heating tube or lamp battle array, just can transfer to heat sink temperature 135 ℃～-80 ℃ scope work.And the uniformity coefficient of heat sink temperature is ± 1 ℃ of scope.
The utility model content
The utility model provides a kind of sandwich-type heat sink, and this sandwich-type is heat sink to reach the contact area of 100% heat interchange, and heat sink temperature is adjustable between-80 ℃～+ 135 ℃.
A kind of sandwich-type is heat sink, comprises inner core, urceolus, base plate, blend stop, parting bead, feed liquor house steward and fluid house steward; Wherein inner core and urceolus are hollow circular steel cylinder, the excircle of inner core is to the welding parting bead, parting bead is radially equidistantly arranged on the circle outer tube, has uniform horizontal deep-slotted chip breaker on the corresponding surface of parting bead and inner core welding, and purpose is the homogeneity that reinforcement refrigerant or heating agent flow in tube; The inner core integral assembling advances urceolus, and the gap between inner core and the urceolus left and right sides both ends of the surface is by the blend stop welded seal; Floor level is installed in the middle and lower part of inner core, is used to place test piece; The urceolus top has liquid outlet, and liquid outlet connects the fluid house steward, and the below has inlet, and inlet connects the feed liquor house steward, for guaranteeing heat sink temperature uniformity ± 1 ℃ of scope, adopts 3 to 4 groups of feed liquor house stewards arranged side by side and fluid house steward.
Working method: after refrigerant flows into gap between inner core and the urceolus by feed liquor house steward arranged side by side, because the effect of parting bead has increased the flow path of refrigerant in heat sink; Translot on the parting bead makes refrigerant form the circulation path in heat sink and guarantees the homogeneity of heat sink temperature control, and refrigerant is full of behind the whole heat sink space discharges by the fluid house steward again, the most heat sinkly after constantly circulating controls to default temperature.
In addition, have lead on inner core and the outer tube wall and introduce the hole; Alcohol or wide journey conduction oil are used in heat sink permission, need install well heater additional or lay heating tube at the urceolus circumference during for medium with alcohol; Can be when being used for wide journey conduction oil without heating tube,
Beneficial effect:
(1) can increase by 3 times than coiled and the heat sink heat exchange area of plshy bone open, realize 100% contact.
(2) simplify heat sink structure, and reduced production costs, shortened manufacturing schedule.
(3) temperature rate has shortened the test period than coiled with plshy bone open is heat sink has improved 2～4 times.
