Description

High power device heat abstractor in a kind of underwater sealing cabin
Technical field
The present invention relates to technical field of heat dissipation, high power device heat abstractor in specifically a kind of underwater sealing cabin.
Background technology
, it is necessary to which under water using high power device, such high power device is arranged in some deep-sea detecting operations It can bear in the sealed compartment of high pressure;In sealed environment, the heat that the equipment inside sealed compartment is produced when working by high power device Amount is difficult to be dispersed into outside sealed compartment by air circulation, device overheat can be caused to be run down to equipment dangerous, unstable;Adopt It can preferably solve the heat dissipation problem of such high power device with the method for heat-pipe radiator, but heat-pipe radiator structure Complexity, high cost, working life are short;It is unsuitable for using for a long time under water, replacing maintenance cost is big, maintenance difficulties are big;Fluid media (medium) The heat that heat-conducting method can be used to produce high power device is transmitted to sealed compartment housing, but in deep water, closed environment, The flowing of fluid and other associated specifications are difficult to realize, and the installation cost of driving equipment is too high, causes its heat conduction efficiency It is very low, it is more difficult to be applied in reality;For the foregoing reasons, it is necessary to seek radiating that is a kind of simple, efficient and being easy to implement Structure, to solve high power device heat dissipation problem in underwater sealing cabin.
The content of the invention
It is an object of the invention to provide high power device in underwater sealing cabin that is a kind of simple, efficient and being easy to implement Heat abstractor, the problem of to solve to propose in above-mentioned background technology;The device can bear wet hyperbaric environment and keep sealing, Good heat dissipation effect of the high power device under the conditions of working long hours inside sealed compartment, internal temperature rise will not be too high and causes excess temperature Phenomenon.
To achieve the above object, the present invention provides following technical scheme:
High power device heat abstractor in a kind of underwater sealing cabin, including inner polygon heat dissipation cabin, the inner polygon dissipate Hot cabin is in the cylinder with hollow structure, and the section of its hollow structure is regular polygon, inner polygon heat dissipation cabin inner wall smooth, Heat-conducting base for fixing high power device is installed on inwall, high power device is fixed on the upper surface of heat-conducting base On.
It is used as further scheme of the invention:The inner polygon heat dissipation cabin is made up of metal material.
It is used as further scheme of the invention:The material of the heat-conducting base is copper or aluminium.
It is used as further scheme of the invention:Thermal conductive silicon is filled between heat-conducting base and the inner polygon heat dissipation cabin Fat and graphite film pad;Heat-conducting silicone grease and graphite film pad are filled between the high power device and heat-conducting base.
It is used as further scheme of the invention:The inner polygon heat dissipation cabin outer surface is covered with antioxidant coating.
Compared with prior art, the beneficial effects of the invention are as follows:Heat-conducting base of the present invention is the fabulous copper product that radiates, and Heat Conduction Material is filled between base and nacelle so that base is fully contacted with nacelle, by heat exchange principle, by nacelle internal heat The low nacelle surface of temperature is transmitted to, is radiated using seawater;Heat conductivility is strong, and the heat that high power device is produced is passed through Heat-conducting base is sent to heat dissipation cabin bulkhead, between heat-conducting base and inner polygon heat dissipation cabin, between high power device and heat-conducting base Micro gap be filled up completely with by heat-conducting silicone grease and graphite film pad, it is to avoid residual air causes heat conduction excessively slow in gap Situation so that outside seawater can take away the heat in heat dissipation cabin rapidly by heat exchange;Cooled down using idle, without water pump Or other driving equipments, passive heat radiation, no cooling energy consumption, more save the energy, environmental protection;Reliability is high, simple for structure Compact, working stability, no starting problem, Maintenance free changes consumptive material, long service life;Low manufacture cost, environmental protection, utilize work Environment distributes heat, and product cost is much smaller than sets heating tube heat abstractor or using other fluid for radiating heat dress in sealed compartment Put, heat abstractor is environmentally friendly in itself without discharge, good heat dissipation effect.

Embodiment
The technical scheme of this patent is described in more detail with reference to embodiment.
Refer to high power device heat abstractor in Fig. 1-2, a kind of underwater sealing cabin, including inner polygon heat dissipation cabin 1, institute It is in the cylinder with hollow structure to state inner polygon heat dissipation cabin 1, and the section of its hollow structure is regular polygon, and inner polygon dissipates The hot inner wall smooth of cabin 1, is provided with the heat-conducting base 2 for fixing high power device 3 on inwall, and high power device 3 is fixed on On the upper surface of heat-conducting base 2.
The heat that the present invention produces high power device 2 is delivered to the cylinder of inner polygon heat dissipation cabin 1 by heat dissipation base 2 On body, heat exchange is then carried out by the seawater and the bulkhead of inner polygon heat dissipation cabin 1 of flows outside, so as to bring heat into water In, the radiating of high power device 3 is realized, its stable operation is maintained.
The inner and outer surfaces of inner polygon heat dissipation cabin 1 are smooth, and the outer surface of inner polygon heat dissipation cabin 1 is applied covered with anti-oxidant Layer influences service life to prevent that heat dissipation cabin from being corroded in the seawater;The inner polygon heat dissipation cabin 1 is by metal material system Into preferably material is aluminum alloy material, and the material of heat-conducting base 2 is copper or aluminium, and there is aluminium alloy light weight, high intensity, height to lead The advantages of hot coefficient, it is adapted to the manufacture in underwater sealing cabin.
Contact surface is smooth between the high power device 3 and heat-conducting base 2, but unavoidably there is small seam Gap, the gap between gap, high power device 3 and heat-conducting base 2 between heat-conducting base 2 and inner polygon heat dissipation cabin 1 is filled out Heat-conducting silicone grease and graphite film pad are filled, increases contact area, heat-conducting silicone grease and graphite film pad thermal conductivity factor are high, are conducive to Heat is quickly delivered on heat-conducting base 2, is conducive to heat to be quickly delivered to the cabin of inner polygon heat dissipation cabin 1 from heat-conducting base 2 Wall, heat exchange is carried out with seawater.
The better embodiment to this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party , can also be on the premise of this patent objective not be departed from formula, the knowledge that one skilled in the relevant art possesses Make a variety of changes.
