Though the heat that 1 heat radiation of traditional quadrature post utilizes air to derive integration rod 1 as conductive medium, because the transmissibility factor of air is low so the thermal contact resistance height makes radiating efficiency relatively poor than solid; Therefore in order to increase radiating efficiency or heat and can't effectively to discharge, be to adopt the forced convertion mode, promptly set up fan and add strong convection, but fan rotates and can produce noise, environment is viewed and admired in interference, and integration rod 1 is that its transmissibility factor of glass material is low, so fan directly dispels the heat to integration rod 1, its heat of taking away is limited; Therefore, utilize traditional perforate 3 or set up the mode that fan produces forced convertion, all can't effectively reach heat radiation.
Summary of the invention
One object of the present invention, provide a kind of integration rod bearing device, utilize outside surface to have the supporting parts of heat sinking function design, and the filling heat-conductive material between integration rod and supporting parts to reduce thermal contact resistance, make the integration rod heat can be effectively dissipate to cooling fluid, and then improve radiating efficiency via conduction material, supporting parts.
Another object of the present invention provides a kind of integration rod bearing device, can make the supporting parts of same size be applicable to the integration rod of various sizes, uses elasticity to improve, and reduces cost of parts.
Another purpose of the present invention provides a kind of integration rod bearing device, can utilize the setting of heat pipe, and the heat of integration rod is sent to the position of preferable natural convection or forced convertion, to strengthen radiating effect.
For reaching above-mentioned purpose, integration rod bearing device of the present invention is to be arranged at the integration rod outside, it comprises that an outside surface has the supporting parts of fin structure, this supporting parts can be heat-radiating substrate, and the gap between supporting parts and integration rod is filled with conduction material, after the heat of integration rod can be derived by conduction material, conduct to supporting parts and utilize natural convection or forced convertion mode that heat is taken away again and reach heat radiation; Can set up heat pipe one end in addition and be connected in supporting parts, the other end connects heat abstractor, the heat of integration rod can be sent to the position of preferable natural convection or forced convertion to reach the heat radiation requirement by the characteristic of heat pipe.

Embodiment
Relevant the present invention is for achieving the above object, and technological means that is adopted and complementary work thereof are imitated, and with following preferred embodiment, and conjunction with figs. is illustrated as follows:
See also shown in Figure 2ly, it comprises a supporting parts 11 integration rod bearing device of the present invention 10, and supporting parts 11 is to be arranged at an integration rod 20 outsides, and this supporting parts 11 and 20 of integration rod are filled with conduction material 12; The shape of this supporting parts 11 can be according to space and integration rod 20 shape and is established, present embodiment cooperates integration rod 20 and is made as a hollow cylinder, its hollow space is ccontaining for integration rod 20, this supporting parts 11 is made up of a heat-radiating substrate 111 and a plurality of fin 112, this heat-radiating substrate 111 is to be made by the high heat-conduction coefficient material, as aluminium, copper etc., 111 liang of outer side surfaces of heat-radiating substrate are provided with fin 112, and 112 of fins are provided with plane 1121 in order to adjusting gear or anchor clamps clamping resistance.
Right fin 112 can be arranged at least one outer side surface of heat-radiating substrate 111, and the position of fin 112, quantity and size are to design and to do suitably to dispose according to space and runner, then can set up fin 112 as the zone that natural convection is good more, cause rate to increase heat exchange area and heat conduction, for example fin 112 also can be arranged at heat sink 111 around (as shown in Figure 3), a side (as shown in Figure 4) or extend to form (as shown in Figure 5) etc. by heat-radiating substrate 111 1 ends.
Please continue ginseng Fig. 2, the surface of this supporting parts 11 offers at least one first filler hole 113 and the second filler hole 114, after the viscose glue (solidifying glue as UV) of higher tack can be injected by the first filler hole 113, supporting parts 11 is fixing with integration rod 20 adhesions, and conduction material 12 (as heat-conducting glue or heat-conducting cream etc.) can be by after 114 injections of the second filler hole, be filled in the gap of 11 of integration rod 20 and supporting parts, therefore, can make the integration rod of the supporting parts of same size by filling conduction material 12 applicable to various sizes, use elasticity and improve, reduce cost of parts, conduction material 12 can reduce thermal contact resistance again and increase conducting effect simultaneously.
The heat of integration rod 20 can see through conduction material 12 and conduct to supporting parts 11 and outside fin 112, relend the heat of taking away supporting parts 11 by intrasystem natural convection and reach heat radiation, because the present invention exports to supporting parts 11 by conduction material 12 with the heat of integration rod 20, dispel the heat again, the more traditional fluid of its conducting effect is good as conductive medium, and not directly to integration rod 20 heat radiations, and with paramount transmissibility factor of thermal conductance and the bigger supporting parts 11 of heat exchange area, dispel the heat again, therefore, can increase radiating efficiency.Can also cooperate the forced convertion mode to strengthen heat exchange phenomenon in addition, and improve radiating effect.
