Abstract
The invention discloses a hexa-gyrate type plate structure heat sink which mainly comprises a pipeline and fins, the pipeline is mainly formed by welding a straight pipe and a 180-degree elbow, the selection form of the fins can adopt a plurality of schemes, and the heat sink adopts a down-in and up-out type and is provided with six fluid inlets and six fluid outlets. According to different adsorbed gas, the materials of the pipeline and the fins are different, and a commonly used wall plate is formed by welding copper fins and a stainless steel branch pipe, wherein the stainless steel pipe is internally filled with a refrigerating medium.
Description
[technical field]
The present invention relates to be used for the hexa-gyrate type plate structure heat sink design at seal head of vacuum container place.The present invention is applied to the hexa-gyrate type plate structure heat sink design at horizontal vacuum vessel head place especially.
[background technology]
Heat sink is the important component part of space environment simulation equipment, and its effect is the cold darkness environment of virtual space on the ground.Its uniformity of temperature profile degree will directly have influence on the simulation precision of space environment.
Satisfy uniformity requirement for heat sink wall surface temperature is distributed, currently large-scalely heat sinkly generally be divided into some, each sheet all has flow control circuit separately, realizes that by liquid nitrogen, gas nitrogen or the liquid helium flow of regulating each road heat sink cover surface temperature distribution is even.But, because the arm assignment of traffic of heat sink inside is by its internal structure decision, if heat sink burst, design such as each chip architecture and shape is unreasonable, whole heat sink wall surface temperature distribution character inadequate natural endowment, then only depend on Flow-rate adjustment that heat sink wall surface temperature is evenly distributed, although proposed the notion of heat sink thermal design at the beginning of the eighties, but owing to lack necessary theoretical method and design means, so when design, can not more accurately calculate its assignment of traffic and Temperature Distribution, design each heat sink the time to temperature the requirement that evenly distributes can't system consider, and can only estimate roughly according to total thermal force of being born, cause that some heat sink temperatures at localized regions are higher or on the low side in many cases.
The heat sink straight pipe type slab construction that all adopts in present end socket place, as KM series vacuum tank, the end socket place is heat sink all to adopt the straight pipe type flat plate structure heat sink, this heat sink structure fluid (liquid nitrogen, gas nitrogen, liquid helium) along the short (liquid nitrogen of journey, gas nitrogen, liquid helium), can not make full use of fluid (liquid nitrogen during heat sink precooling, gas nitrogen, liquid helium) the latent heat of vaporization and sensible heat, very easily cause and run the liquid phenomenon, not only waste experimental resources but also increase experimental cost, especially concerning the liquid helium of costliness, the consumption of liquid helium had become the emphasis of heat sink design when the uniformity that how can guarantee heat sink temperature can reduce precooling again.According to this deficiency, with the heat sink hexa-gyrate type plate structure that is designed at seal head of vacuum container place, as shown in Figure 1, this kind structure has effectively increased fluid and has flowed along journey, has utilized the latent heat of vaporization and the sensible heat of fluid fully.
[summary of the invention]
The purpose of this invention is to provide a kind of hexa-gyrate type plate structure heat sink design that is used for the seal head of vacuum container place.
As shown in Figure 1, hexa-gyrate type plate structure heat sink mainly is made up of pipeline and fin, and pipeline mainly is welded by straight tube and one half bend, and the selection form of fin can adopt multiple scheme, advance to go up removing from mould under this heat sink employing, six fluid inlets and six fluid issuings are arranged.According to the difference of adsorbed gas, the selection of pipeline and fin is different, and wallboard commonly used is to be welded by copper fin and stainless steel arm, wherein logical refrigerant in the stainless steel tube.
The advantage that the present invention has is: (a) adopted the swirl type circuit design, utilized the useful space at seal head of vacuum container place fully; (b) having increased fluid flows along journey; (c) can be according to different Demand Design tube pitch; (d) material adopts stainless steel tube and copper fin; (e) advance to go up removing from mould under heat sink import and export are adopted, avoid the stifled generation of gas; (f) latent heat of vaporization and the sensible heat of fluid have been utilized fully; (g) energy savings reduces experimental cost.

[specific embodiment]
Further specify the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, hexa-gyrate type plate structure heat sink mainly is made up of pipeline and fin, and pipeline is welded by straight tube and one half bend, and the selection form of fin can adopt multiple scheme, advance to go up removing from mould under this heat sink employing, six fluid inlets and six fluid issuings are arranged.
According to the difference of adsorbed gas, the selection of pipeline and fin is different, and wallboard commonly used is to be welded by copper fin and stainless steel tube, wherein logical refrigerant in the stainless steel tube.
