Description
Technical field
The utility model content belongs to the thermal hardware technical field, relates to a kind of integrated heat pipe.
Background technology
Known at present and widely used various molten steel gravity assisted heat pipe moves under heat condition for a long time; Accumulate in heat pipe top and then occupied the heat pipe condensation space because the hydrogen in the electrochemical effect water is separated; The heat release usefulness that causes of a specified duration decays; Cause heat pipe failure, this phenomenon seriously influences the heat exchange usefulness of heat pipe and reduces heat pipe service life.
The utility model content
The purpose of the utility model is the shortcoming and defect that prior art exists is overcome, provide a kind of rational in infrastructure, can get rid of that incondensable gas, hot property in the heat pipe is stable, the integrated heat pipe in service life.
For realizing that the technical scheme that the foregoing invention purpose adopts is such: the integrated heat pipe that is provided comprises heat pipe, lower collector pipe, lower collecting box, upper header and upper header; It is characterized in that: the bottom of heat pipe is connected with lower collector pipe; One port of lower collector pipe is connected with lower collecting box, and the top of heat pipe is connected with upper header, and a port of upper header is connected with upper header; Be provided with temperature sensor and blast pipe on the top of upper header; Air bleeding valve is housed on blast pipe, liquid supplementation pipe is housed on lower collecting box, valve is housed on liquid supplementation pipe.
The further technical scheme of the utility model comprises: vacuum-pumping tube is equipped with on the top at upper header, and vacuum valve is housed on vacuum-pumping tube.
The further technical scheme of the utility model also comprises: heat pipe is divided into bringing-up section and condensation segment, and the bringing-up section upper header is connected with the condensation segment upper header by tedge, and the bringing-up section lower collecting box is connected with the condensation segment lower collecting box by down-comer.
In actual motion, what produce in the integrated heat pipe is that main incondensable gas is satisfied the upper header that gathers gradually with hydrogen, because of the incondensable gas heat conductivility very little; Form thermal resistance, when incondensable gas reached certain amount in upper header, the temperature of this part obviously reduced; Reach the lower limit of setting when temperature after, temperature sensor sends signal, at this moment can open air bleeding valve and discharge incondensable gas; Then close air bleeding valve return to the operating temperature of setting when temperature after, guarantee the heat exchange usefulness of heat pipe.Integrated heat pipe is provided with automatic control system, through the variation of temperature parameter on the temperature sensor the not cool gas flow with fixed attention and the medium amount in space in the integrated heat pipe is carried out STOCHASTIC CONTROL, keeps integrated heat pipe to be in normal operating condition for a long time.After the long-time running, the medium in the heat pipe has certain loss, can replenish through the liquid supplementation pipe of lower collecting box.
Compared with prior art; The good effect that the utility model produces is: the coherent condition of the temperature sensor decidable incondensable gas through integrated heat pipe upper header top is also in time discharged; Keep the normal heat exchange usefulness of heat pipe, is significantly improved the service life of integrated heat pipe.
Description of drawings
Fig. 1 is the principle schematic of an embodiment of the described integrated heat pipe of the utility model.
Fig. 2 is the principle schematic of the embodiment of the described a kind of split integrated heat pipe of the utility model.
The title of each label is respectively in the accompanying drawing: 1-lower collector pipe, 2-heat pipe, 3 lower collecting box, 4-bringing-up section, 5-liquid supplementation pipe; 6 valves, 7 dividing plates, 8-condensation segment, 9-upper header, 10-upper header; The 11-temperature sensor, 12-air bleeding valve, 13-blast pipe, 14-vacuum valve, 15-vacuum-pumping tube; The 16-heating component, 17-down-comer, 18 tedges, 19-condensation
The specific embodiment
Below in conjunction with accompanying drawing the utility model content is further specified, but the practical application form of the utility model is not limited in illustrated embodiment.
Referring to accompanying drawing 1, the described integrated heat pipe of the utility model mainly is made up of heat pipe 2, lower collector pipe 1, lower collecting box 3, upper header 9, upper header 10.Every row heat pipe is linked up by upper and lower collector 9,1, and upper and lower header 3,10 is linked to be an integral body to every row heat pipe through upper and lower collector 9,1 again.The top of upper header 10 is provided with temperature sensor 11 and blast pipe 13, and air bleeding valve 12 is housed on the blast pipe 13.Liquid supplementation pipe 5 is housed on the lower collecting box 3, valve 6 is housed on the liquid supplementation pipe 5, the integrated heat pipe bottom is a bringing-up section 4, and top is condensation segment 8.On upper header top vacuum-pumping tube 15 is housed, vacuum-pumping tube is equipped with vacuum valve 14.
In real work, the medium in the heat pipe liquefies after condensation segment 8 heat releases in bringing-up section 4 gasifications, returns bringing-up section 4 by gravity again, and medium goes round and begins again, and the mode with phase transformation is transferred to low-temperature receiver to heat from thermal source efficiently in the space of sealing.The incondensable gas that top, heat pipe space collection is deposited in running, what of the variation reflection amount through temperature parameter reach capping and can open air bleeding valve and in time discharge, and keep the integrated heat pipe normal condition.In exhaust, take medium steam rather out of, carry out periodic monitor heat pipe liquid level, carry out fluid infusion through contactless liquid level gauge.Also automatic control system can be set, the non-condensation gas scale of construction and the medium amount in space in the integrated heat pipe are carried out STOCHASTIC CONTROL, keep the normal running status of integrated heat pipe.
Integrated heat pipe will vacuumize before operation, and vacuum reaches setting value and closes vacuum valve.Integrated heat pipe need not vacuumize and seal these two technical process in manufacture process.
Shown in the accompanying drawing 1 is that the monoblock type integrated heat pipe is divided into two parts up and down to it by dividing plate 7, and the bottom is a bringing-up section 4, and top is condensation segment.This structure mainly is applicable to gas-gas heat exchange, like air preheater.
