Embodiment one
Fig. 1 is please referred to, the present embodiment provides a kind of thermal column radiators comprising plume 50, multiple fins 20, upper cover plate
10, lower cover plate 40, side support 30 and fixing seat 60.
Plume 50 is the cylinder with chassis 51, and 50 inner hollow of plume is connected to the inside on chassis 51,51 face paste of chassis
Chip is closed, the area in 51 face of chassis is greater than the radial cross-section product of plume 50, and such setting increases the fitting area of chip,
Conducive to heat dissipation.The working principle of plume 50 is identical as heat pipe, the evaporation that plume 50 passes through the working solution in Totally enclosed vacuum shell
Transmit heat with condensation, with high thermal conductivity, good isothermal, cold and hot two sides heat transfer area can arbitrarily change,
Can series of advantages, the plume 50 such as remotely transferring, temperature controllable copper pipe inner wall sintered copper powder can be used, then in plume 50
Portion vacuumizes, and fills deionized water, and copper pipe sealing two ends make plume 50 become sealing two ends, and inside circulation has dissipating for working solution
The producing principle of heat structure, plume 50 refers to hot tube process.Radiator structure of the plume 50 as high thermal conductivity coefficient, thermal coefficient can
Up to more than 20000w/ (M.k), plume 50 is relative to heat pipe, and the internal cavity space of plume 50 is big, and working solution evaporation capacity is big, more
Add suitable small size, high-power cooling application.
Chip is attached on 51 face of chassis of plume 50, and chip fever conducts heat on the chassis 51 of plume 50, chassis
51 internal liquids evaporate under the conditions of low vacuum takes away heat, then hot steam from chassis 51 to plume 50 above flow, uplink
Water is condensed into the cold, chassis 51 is sucked back by the capillary structure of 50 inner wall of plume, is evaporated again, and in cycles, chip is carried out
Heat dissipation.
50 outer surface of plume is provided with multiple fins 20, increases heat dissipation area, to thermal column radiator side blow when, heat
Amount is pulled away from fin 20, accelerates radiating rate.

The connection of fin 20 and plume 50 is by a circular through hole among fin 20, under regular situation, 50 He of plume
Following two problems easily occurs in 20 installation process of fin: fin 20 is rotated around cylinder causes positional fault；Thin fin 20 is easy to become
Shape, bending.Therefore the combination of fin 20 and plume 50 influences heat dissipation very big.The present embodiment is by being arranged multiple pads and leading to
It crosses tin cream plume 50 and fin 20 are welded and fixed, as shown in figure 4, multiple welding hole M, welding hole M are arranged in the through-hole edge of fin 20
Place is pad, and the position welding hole M on multiple fins 20 is identical, and the welding hole M for the fins set that multiple fins 20 are formed is in through-hole
Axial direction forms welding duct D, and tin cream is heated mobility, and tin cream is filled up welding duct D, fills fin 20 and plume 50
Between gap, complete welding.
As shown in figure 3, on same level, welding hole M and 50 circle center line connecting of plume on fin 20, between adjacent welding hole M
Welding hole angle a is formed, welding hole angle a is between 30~60 °.Welding hole angle a between adjacent welding hole M can be identical, can also be with
Difference, those skilled in the art are arranged according to actual needs.
When using tin cream welding operation, illustratively, position as shown in Figure 6 puts soldering furnace welding into, and tin cream passes through note
Emitter throws welding duct D into, and when welding hole angle a is less than 30 °, tin cream cannot penetrate into the bottommost of welding duct D, welding hole folder
When angle a is greater than 60 °, welding hole M will be arranged in the lower section of 50 center line of plume shown in fig. 6, inject tin cream into welding duct D
When tin cream can fall welding duct D outside fin 20 on, influence the heat dissipation of fin 20, three welding hole M are arranged in Fig. 6
The top of 50 center line of plume is avoided that tin cream falls on the fin 20 outside welding duct D.
Preferably, the welding hole angle a between adjacent welding hole M is 45 ° of settings, can effectively be avoided between fin 20 and plume 50
Welding surface missing solder, while shorten tin cream welding duct D in flowing velocity, weld plume 50 with fin 20 firm, subtract
Few thermal resistance, improves welding quality.
Illustratively, as shown in figure 4, three welding hole M are arranged between fin 20 and plume 50, three welding duct D are formed.
Upper cover plate 10 and lower cover plate 40, upper cover plate 10 and lower cover plate is respectively set at the axial both ends of plume 50 in fins set
40 side flange is also connected with connecting plate at flange, and connecting plate is equipped with bolt column 81, and the peripheral wall of bolt column 81 is equipped with spiral shell
Line；Side support 30 is arranged in the radial side of plume 50 in fins set, illustratively, as shown in Fig. 2, side support 30 is quadrangle
Frame, four angles of frame are equipped with connecting hole, and the bolt column 81 on upper cover plate 10 and lower cover plate 40 is each passed through the company of frame
It connects hole and is fixed by nut 82, side support 30 and upper cover plate 10 and lower cover plate 40 is fixed.
The side flange of side support 30 and 10 junction of upper cover plate, connecting plate is equipped at flange, and connecting plate is equipped with spiral shell
Hitching post 81 is equipped with connecting hole at 10 flange of upper cover plate, and the bolt column 81 on side support 30 passes through the connecting hole of upper cover plate 10, into
One step is fixed by side support 30 and upper cover plate 10, and the side support 30 of two sides limits fin 20 and rotates.
Fin 20 is softer, in unshielded situation, is easily deformed, crawl, and transport and installation are inconvenient, upper cover plate
10 and lower cover plate 40 fin 20 is encased using aluminium sheet bending, while side support 30 is set, the surrounding of fin 20 is protected
Firmly, 20 rotational deformation of fin is prevented, makes thermal column radiator that there is better performance, avoids 20 bump injury of fin, overcome fin 20
Be easily deformed, deviation the problem of, be also convenient for grabbing, transport and install.
