Embodiment
Below in conjunction with drawings and Examples, the present invention will be further described.
In Fig. 1, technical scheme of the present invention provides a kind of indoor transformer/reactor sound insulation heat sink, it is on the wall of described transformer/reactor chamber, at least one rectangular box-like housing 1 is set, in rectangular box-like housing, gas-gas-heat exchanger is set, for absorbing the indoor air heat source of transformer/reactor.
Its gas-gas-heat exchanger is the heat exchanger with a branch of heat pipe 3 formations of radiating fin 4.
Heat exchanger in the technical program, the heat transfer pattern of employing sound insulation/dust-separation, is disposed to outdoor by indoor air heat source conduction.
Concrete, described rectangular box-like housing runs through described transformer/reactor chamber and outdoor adjacent wall setting.
In described rectangular box-like housing, a thermal baffle 2 is set, for indoor and outdoor environment is isolated, play the sound insulation/dust-separation effect between space, indoor and outdoor, and described heat pipe Shu Jinhang is supported/fixes.
On thermal baffle, run through and be provided with the heat pipe bundle being formed by a plurality of heat pipes 3, as heat-conduction component.
Indoor and outside at described rectangular box-like housing, arrange respectively circulating ventilation heat exchanger channels, forms indoor high-temperature gas circulation canal 5 and outdoor cryogenic gas circulation canal 6.
When described indoor high-temperature gas and outdoor cryogenic gas flow through respectively simultaneously in passage separately, described hot tube bundle heat exchanger is passed to outdoor cryogenic gas by the heat of indoor high-temperature gas, thereby realize the heat exchange of two kinds of gases, realize by this sound insulation cooling of transformer/reactor chamber under sound insulation/dust-separation pattern.
Further, described thermal baffle and described transformer/reactor chamber and outdoor adjacent wall are coaxially set.
At the heat pipe two ends that are positioned at described thermal baffle both sides, be provided with many group radiating fins 4, form respectively hot junction and the cold junction of heat pipe bundle heat-exchanger rig, the hot junction of heat pipe bundle heat-exchanger rig described in it, be positioned at the indoor of rectangular box-like housing, the cold junction of described heat pipe bundle heat-exchanger rig, is positioned at the outside of rectangular box-like housing, between the hot junction and cold junction of described heat pipe bundle heat-exchanger rig, by described thermal baffle, carry out sound insulation and dust-separation.
Described indoor high-temperature gas circulation canal and outdoor cryogenic gas circulation canal are but heat exchanger channels of air blast cooling, and its force ventilated power source is axial flow blower (not shown).
As seen from the figure, the heat pipe described in it, runs through and is arranged on thermal baffle " interior low outer height ", and the position of the evaporation ends of heat pipe (being positioned at indoor) is lower than its condensation end (being positioned at outside).
Angle between heat pipe and thermal baffle (being commonly called as inclination angle) α is less than 90 °, and each heat pipe being arranged on same thermal baffle shares one group of radiating fin.
Heat pipe inclination alpha mainly contains two effects: (1) heat pipe adopts behind certain inclination angle, is conducive to condensed liquid working substance in condensation end of heat pipe and gets back to rapidly evaporation section, realizes efficient heat transfer; (2) heat pipe adopts behind certain inclination angle, can increase the front face area between fin and heat exchange wind, improves heat dispersion.

Hot rainbow formula heat pipe is identical with liquid-sucking core heat pipe operation principle, and unique different place is that inside heat pipe does not have liquid-sucking core or working medium not to possess stronger capillary attraction, and working medium refluxes and mainly relies on gravity, so heat pipe just works conventionally when vertical placement.
Heat transfer technology of heat pipe takes full advantage of the Rapid Thermal hereditary property of heat-conduction principle and refrigerant, sees through heat pipe the heat of thermal objects is delivered to rapidly outside thermal source, and its capacity of heat transmission surpasses the capacity of heat transmission of any known metal.
Adopt heat transfer technology of heat pipe, even if make heat abstractor adopt the slow-speed of revolution, low air quantity motor, can obtain equally satisfied radiating effect.
