Description
Technical field
The present invention relates to a kind of soaking plate.
Background technology
Develop rapidly along with industries such as IT, communication, LED, solar energy, wherein the heating power of used electronic element is also improving constantly, the miniaturization of electrical equipment simultaneously, the heat flow density of the electrical equipment that makes significantly increases, and the extensive use that utilizes traditional radiating subassembly to be difficult to the hot arraign Ti ﹐ Vapor chamber that well solution is relevant provides more, better thinking for overcoming these problems.
The topmost advantage of soaking plate (Vapor Chamber) is that not only its heat exchange surface and heat flow density are much larger than general heat pipe (Heat Pipe), and because the relative heat pipe of soaking plate (Vapor chamber) has very big evaporation gas flow area, the backflow capillary force can satisfy that condensate liquid reflux to require before put the defeated heat of maximum that ﹐ can effectively improve soaking plate (Vapor chamber), and can satisfy the heat dissipation problem of multiple spot thermal source, big (utilizing latent heat) ﹑ volume in light weight, little (hollow container) ﹑ Jie structure Jian Dan ﹑ can be in characteristics such as agravic runnings after the match because soaking plate (Vapor chamber) has Wen degree Fen cloth Jun Yun ﹑ thermal resistance Xiao ﹑ thermal response Kuai Su ﹑ heat output.So it is widely used in hot biography fields such as IT ﹑ Tong Xun ﹑ Dian ﹑ Dian Li ﹑ Aero-Space.
But in the design and processing and making process of soaking plate (Vapor chamber), keep the design and the layout of the good locking mechanism (screw, double-screw bolt, shell fragment etc.) that contacts to exist following difficult point in order to guarantee soaking plate (Vapor chamber) and heat dissipation element:
In traditional soaking plate (Vapor chamber) locking mechanism design, how to open on soaking plate (Vapor chamber) surface that via hole adds copper sheathing or to be sealed supporting mechanism with via hole, facilitate the use the spring attachment screw carry out sealed, as shown in Figure 1.Fig. 2 is traditional arranging in the last sealed perforate of using soaking plate (Vapor chamber) of server (Server), and Fig. 3 is that the perforate that soaking plate (Vapor chamber) is used on many thermals source is arranged.
As Fig. 2, shown in Figure 3, in order to increase the sealed perforate of mechanism, diverse location and requirement according to CPU or application thermal source increase via hole at diverse location and zone.Because soaking plate (Vapor chamber) application need is steam flow channel fully reasonably, so the hollow of mostly being (or tool portion hollow) structure, its intensity can reduce greatly.As figure two soaking plate (Vapor chamber) when mechanism is sealed, might cause that the CPU zone deforms, have a strong impact on soaking plate (Vapor chamber) and CPU(or thermal source) contact effect, thermal contact resistance is significantly promoted, influence radiating effect, so under the prerequisite that guarantees soaking plate (Vapor chamber) performance, how the position and the locking mode of flexible topology's locking mechanism are extremely important, but conventional welding method can only be made position, the hole layout type as Fig. 2, Fig. 3 pattern.
Soaking plate structure as shown in Figure 3 because the existence of many thermals source or the restriction of design condition, is carried in the mesozone and has been increased a sealed via hole in order to increase sealed effect, has not only dwindled steam void, and steam flow also become not smooth and easy; Simultaneously, at soaking plate (Vapor chamber) opening area, can form heat and pass inactive area, thereby reduce effective usable floor area of soaking plate (Vapor chamber).These all can cause the performance of monoblock soaking plate (Vapor chamber) to descend.
Owing to the sealed needs of mechanism, going up left side, CPU zone in soaking plate (Vapor chamber) has increased a shell fragment in Fig. 4.Method commonly used is to use soldering that shell fragment and soaking plate (Vapor chamber) are welded together, but because soaking plate (Vapor chamber) has extraordinary heat diffusivity, amount of localized heat can be diffused into whole soaking plate (Vapor chamber) very soon, make local welding be difficult to meet the requirements of welding temperature, and too high temperature may cause that soaking plate (Vapor chamber) plays problems such as drum distortion, so local heat mode commonly used is difficult to shell fragment well is welded to above the soaking plate (Vapor chamber).Can not reach the requirement of strength that mechanism uses even weld together.
Another very important problem, owing to go up increase mechanism via hole in soaking plate (Vapor chamber), so in the seal welding process of soaking plate (Vapor chamber), can cause sealing dew point increases, the seal welding yield descends, and causes soaking plate (Vapor chamber) cost of manufacture to increase.
Summary of the invention
Purpose of the present invention is exactly at above-mentioned defective, and a kind of soaking plate is provided, and includes soaking plate main body 1 and closing component structure 2, and described closing component structure 2 is connected with arbitrary fixed-site of soaking plate main body 1 outer surface by welding.
Described welding manner is stud welding.
Described stud welding may further comprise the steps:
1) need a fixing end to contact closing component structure 2 with the outer surface of soaking plate main body 1;
2), form a molten bath that adapts with closing component structure 2 contact jaw shapes with closing component structure 2 energising and conduct to the welding region that soaking plate main body 1 outer surface causes the soaking plate outer surface and melt;
3) do not exert pressure so that closing component structure 2 is immersed in the described molten bath at closing component structure 2 with the end that soaking plate main body 1 surface contacts;
4) stop energising, leave standstill and treat that the molten bath solidifies.
Described closing component structure 2 is one or more in screw, swivel nut and/or the shell fragment.
Described closing component structure 2 is at least one.
Described stud welding step 2) current type in is a direct current, and intensity is 200-500A.
Described energising welding step 3) pressure in is 20-80N.
Beneficial effect of the present invention is: itself has the following advantages stud welding, 1., weld interval short (＜1s); 2., cooling velocity is fast; 3., need not boring; 4., structural strength is big; 5., welding precision height; 6., all-position welding; 7., save material.Because the above-mentioned advantage of stud welding is highly suitable for soaking plate (Vapor chamber) surface soldered mechanism securing member.Do not need punching on soaking plate (Vapor chamber) surface, help the design of steam void, reduce the steam flow resistance, reduce heat and pass inactive area, increase effective usable floor area of soaking plate (Vapor chamber), promote the heat transfer property of soaking plate (Vapor chamber), better the probability of leaking is welded in control, reduces cost of manufacture.Because stud welding speed is fast, and can cool off fast, can overcome soaking plate (Vapor chamber) fully because the heat-conducting system height, heat transfer rate is unfavorable for the problem of spot welding or local welding soon, can avoid local heat may cause that soaking plate (Vapor chamber) areal deformation plays the problem of drum or depression simultaneously.Stud welding can make securing member and the fusion under the condition of shelf depreciation of soaking plate (Vapor chamber) surface metal-layer, and in conjunction with forming the very big weld layer of intensity, its welding effect can satisfy the structural strength instructions for use fully.And but the high accuracy of welding and all-position welding can satisfied optional position and the zone that mechanism design requires, and implement the welding of structural member.Shown in Fig. 6,7, structural design and distribution are more flexible, thereby better meet various structural design demands.The used securing member of stud welding can satisfy different structural design demands in a different manner for various mechanism parts such as double-screw bolt, swivel nut, shell fragment, screw, springs, thereby provides more, better mentality of designing for mechanism design.
