Description

The location structure of heat abstractor

Technical field

The utility model provides a kind of location structure of heat abstractor, outstanding confession under directions heat pipe heat is located on the location-plate and is given the location structure of the firm solder bond of spacing confession, see through two fins of joint portion on the location-plate and the position-limiting action of backstop, heating tube can displacement or deflection when weld job, reaches accurately, the purpose of stable welding.

Background technology

Scientific and technical information fast development now, and personal computer, electronic memo and mobile computer are because calculation function is strong, speed is fast, therefore by widespread in industry-by-industry, and the arriving of cybertimes more causes the universalness of computing machine, the chip in the computing machine wherein, when equaling to operate, electronic component can produce heat energy, form pyrotoxin, and the fast more heat energy that produces of running speed is high more, for avoiding Yin Gaore to burn pyrotoxins such as chip or electronic component, and the shortening chip, the serviceable life of electronic component etc., therefore can be at each chip, be equipped with heat radiator on the pyrotoxin, make chip, the thermal energy conduction that produces on the pyrotoxin is to heat radiator, dispel the heat to the surface gap of heat radiator with the blow cold air that fan was produced again, yet, because of chip, the volume of pyrotoxin is big, little difference, the radiating mode difference, so need the area size of assembling heating radiator also different, if heating radiator is pattern fixedly, only can use in fixed measure, the pattern matched chip, on the pyrotoxin, can't adjust, change, be subjected to many restrictions during use, extremely inconvenient.

And as No. 292301, several I of TaiWan, China certificate number; the utility model patent of " radiating module "; see also Fig. 6; shown in Figure 7; this heating radiator A is for being configured on the pyrotoxin B; and heating radiator A is provided with locking support A2 in base A1; and be provided with a plurality of fluting A21 in locking support A2 side; and in the base A1 and a plurality of heat pipe A3 of clamping between support A2 that lock; then a plurality of heat pipe A3 one ends are connected in base A1; then assembly fins group of other end A4; the surfaces A 11 that contacts with pyrotoxin B in heating radiator A again; between B1; for disposing heat transfer medium C, then heat transfer medium C is disposed at heat transfer medium over cap C1, and is provided with lid C11 and a plurality of fixed part C12 in heat transfer medium over cap C1; these a plurality of fixed part C12 extend from lid C11 to be provided with; cover heat transfer medium C to see through lid C11, be arranged in respectively among the A21 that respectively slots with a plurality of fixed part C12 again, but when practical application; still there are many disappearances and inconvenience, as:

(1) between the base A1 of heating radiator A and locking support A2, dispose a plurality of heat pipe A3, but heat pipe A3 is the pipe shape, in when location assembling, be easy to generate the skew of axial turn, and a plurality of heat pipe A3 is respectively towards the inclination of different angles, when collocation assembling fins group A4, accurately contraposition not only increases the difficulty of overall package, contraposition operation, also quite consuming time taking a lot of work.

(2) heating radiator A is provided with heat transfer medium C in base A1; the lid C11 that heat transfer medium C then sees through heat transfer medium over cap C1 is covered to be covered; be held in pyrotoxin B to see through heat transfer medium over cap C1, so will cause heat conducting having some setbacks, the usefulness variation of influence heat radiation.

(3) the heat pipe A3 of heating radiator A is for extending to base A1 top, and in base A1 top assembling fins group A4, then the weight of fins group A4 also down puts on the base A1, also weighs on the pyrotoxin B, causes pyrotoxin B to bear great weight power, and damages easily again.

Be with, how to solve between present location structure and the heat pipe assemble, can't strong fix when welding, the problem of displacement easily, inclination, and influence disappearances such as the follow-up assembling operation of location structure carries out, be the relevant manufacturer that is engaged in the industry and desire most ardently the direction place that research improves.
