Embodiment

Relevant detailed description of the present utility model and technology contents, conjunction with figs. is described as follows.

Please refer to Figure 1 and Figure 2, be three-dimensional exploded view of the present utility model and three-dimensional combination figure, the utility model provides a kind of radiating module, the electronic building brick that is used to generate heat heat radiation, and radiating module comprises holder 10, radiator 20 and temperature-uniforming plate (Vapor Chamber) 30.

Holder 10 offers groove 11, and its both sides also offer through hole 12 respectively, and holder 10 is that the thermal conductivity good metal is made, as metals such as copper, silver; Radiator 20 amplexiforms and is fixed on holder 10 tops, and radiator 20 is that aluminum metal is made.

Radiator 20, comprise base plate 23 and be spaced and amplexiform two or more fin 22 at base plate 23, base plate 23 amplexiforms the top that is fixed on holder 10, the both sides of base plate 23 offer two fixing holes 21, these fin 22 form two accommodation spaces 222 corresponding to two fixing hole 21 places, and are formed with heat dissipation channel 221 between each fin 22.

Temperature-uniforming plate 30 is contained in the groove 11 and with holder 10 and is connected, and the one side of temperature-uniforming plate 30 is amplexiformed radiator 20 bottoms, and another side then amplexiforms described heating electronic building brick (figure does not show); In addition, groove 11 inwalls of holder 10 form block 13, and the outside of temperature-uniforming plate 30 forms and block 13 mutual corresponding flanges 31, and block 13 is connected with flange 31 build-ins.

Temperature-uniforming plate (Vapor Chamber) 30 is the vacuum cavities that inwall has micro-structural, and when heat conducted to evaporating area by thermal source, the workflow of cavity the inside was known from experience in the environment of rough vacuum, begins to produce the phenomenon of liquid phase vaporization.Workflow cognition absorption heat energy and its volume will expand rapidly this moment, and gaseous working fluid can be full of whole cavity very soon; When gaseous working fluid touches a colder phenomenon of condensing that just produces when regional, discharge the heat of being accumulated when the evaporation by the phenomenon of condensing.Liquid workflow cognition after condensing returns evaporation thermal source place by the capillarity of micro-structural, and this running will be carried out in cavity again and again.And the operation principle of temperature-uniforming plate and general heat pipe is identical, and its discrepancy is that heat pipe is the heat exchange pattern of the line of one dimension, and temperature-uniforming plate be the heat exchange pattern of two-dimentional face.
