The utility model is used for reference the principle of vascular plant transpiration and capillarity and is introduced evaporative heat loss and capillary water absorption hydrotechny.As a kind of new technology heating radiator, it is by the metal heat sink with hydrophilic surface layer, with capillary water channel and the having directional exhaust reflux formation of water wetted material.
1, metal heat sink is by heat dissipation metal base, be distributed in a plurality of thermal columns on surface and the water wetted material layer on thermal column surface composition, hydrophilic surface layer is that long fibre thieving paper or wash water are cotton, in same space, the thermal column on dense arrangement and the moistening top layer of tool provides than heat radiator high surface area more for moisture evaporation, and radiating effect is better.
2, water supply installation utilizes the water absorptivity of capillarity and water wetted material, without power constantly to hydrophilic surface layer water delivery.Water wetted material in capillary water channel is degreasing cotton cord or artificial synthetic hydrophilic fibers.
3, having directional exhaust device is by the shell with inlet, outlet, drainage gas outlet, and the vent fan of drainage exhaust pipe mouth forms.Shell can guarantee that in heating radiator, air-flow is directed and water-tight, and drainage gas outlet low level has branch to connect water tank for reflux condensation mode water.Gas outlet end connects exhaust and is fixed on cabinet exhausr port with fan.
The utility model shows with respect to the advantage of prior art (common radiator and water-cooling system):
1. in existing heat dissipation technology simple in structure, common radiator is simple in structure, but only depends on heat conducting and radiating, poor effect, and in order to guarantee radiating effect, often volume is larger; Better but complex structure, cost is expensive for water-cooling system radiating effect, and failure rate is high; The utility model combines the advantage of the two, and in the time of good heat dissipation effect, structure is simple again, energy-conservation, failure rate is low.
2. efficient the utility model adopts directed air intake mode, and heat radiation pillar surface area is larger, and air-flow promotes that evaporation radiating effect is more remarkable, and radiating effect, considerably beyond ordinary hot heat loss through conduction device, can compare favourably and even be better than water-cooled effect with water-cooling system.
3. energy-conservation existing water-cooling heat radiating system demand motive Water Cycle heat radiation, power consumption is huge; Common radiator relies on fan to accelerate heat conducting and radiating, and fan electricity consumption is also large; And the utility model is because adopt directed air intake design, introduce evaporation endothermic technology, radiating effect improves greatly, and fan efficiency is higher, thereby than the more power saving of the heat conducting radiator fan of ordinary hot.
4. the design of safety semitight having directional exhaust of the present utility model and drainage gas outlet reflux tank has guaranteed that the air in cabinet is dry, in capillary water supply installation feed pipe, fill up water wetted material simultaneously, moisture is adsorbed by water wetted material, even if feed pipe breaks, also can not think that water-cooling system equally causes and leaks and the problem of short circuit.Safer compared with water-cooling heat radiating system.
5. resistance to grey ordinary hot heat loss through conduction device is easy to because entering ash stops up thermovent and cannot work, and heating radiator air intake opening of the present utility model has one deck screen pack, for filtering long larger foreign material, conveniently takes off cleaning dredging; Because wet in thermal column surface, a small amount of fine dust is to be only also attached to thermal column surface, and can not stop up heating radiator, does not affect the evaporation on thermal column surface, and only having dust to run up to seriously to block air-flow just needs cleaning.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, content of the present utility model is described in further details.
Embodiment:
Refer to shown in Fig. 1, evaporation-type heat radiator, is fixed in cabinet, and metal heat sink B comprises metal heat sink base B1, is placed with a plurality of thermal column B2 on metal heat sink base B1, the outside of the metal heat sink base B1 heat-generating electronic elements C that is sticked, thermal column B2 surface is provided with water wetted material layer, metal heat sink B is Semi-seal structure, its top is provided with its top and is provided with top cover and air intake opening screen pack A, bottom is connected with gas outlet I, in the casing H of metal heat sink B offside, have exhausr port, in exhaust ports, be provided with vent fan G, the casing H lateral surface of exhausr port below is provided with water tank F, gas outlet I is divided into two branch roads, one bar branch road is connected to exhausr port, , another branch road is condensate return passage E, it is connected to water tank F top, the heat energy that heat-generating electronic elements C produces communicates with gas outlet I by thermal column B2, in casing H, be also provided with the capillary water channel D with water wetted material, it is upper that its epimere is connected to thermal column B2, and its bottom is connected with water tank F.
