Next by the operation principle of the alternation formula three-temperature-zone heat-pipe apparatus of detailed description the present embodiment.The work of alternation formula three-temperature-zone heat-pipe apparatus mainly contains two processes: heating process and cooling procedure.
In heating process, adsorbent bed heat absorption desorption.Specifically, outer casing top interface 14 is connected with high pressure condenser, epicoele 12 pressure increase, act on the also corresponding increase of downward active force on internal layer shell 1, the suffered gravity of this active force and internal layer shell (internal layer shell 1 self, liquid-sucking core 14, heat-pipe working medium 5 three's gravity sums) sum is greater than the saturation pressure of the corresponding heat source temperature of cavity of resorption working medium, internal layer shell 1 is moved downward to cavity of resorption bottom, originally arrive heat source temperature and become the cavity of resorption working medium pressurized liquefaction of gaseous state, be full of cavity of resorption 7 volumes, the cavity of resorption refrigerant heat transfer of thermal source by cavity of resorption wall and after liquefying, the heat-pipe working medium 5 that heating internal layer shell is 1 li, heat-pipe working medium heat absorption evaporation, steam rises to internal layer shell 1 top, by the heat-conducting oil in lumen wall and lumen 10, heat is reached to adsorbent bed, reach the object of thermal source heating adsorption bed, adsorbent bed heat absorption desorption.When heating process, the duty of alternation formula of the present invention three-temperature-zone heat-pipe apparatus is heated condition.In this process, because the upper end of internal layer shell 1 is supported by upper sealing ring 2, epicoele 12 is isolated with lumen 10 and cavity of resorption 7, heat transmission can not occur between low-temperature cooling media and adsorbent bed, thereby improved the efficiency of heating surface.
In cooling procedure, adsorbent bed heat radiation absorption.Specifically, outer casing top interface 14 is connected with low pressure evaporator, epicoele 12 pressure reduce, act on also corresponding the reducing of downward active force on internal layer shell, the suffered gravity of this active force and internal layer shell (internal layer shell 1 self, liquid-sucking core 14, heat-pipe working medium 5 three's gravity sums) sum is less than the saturation pressure of the corresponding heat source temperature of cavity of resorption working medium, cavity of resorption working medium pressure reduces and vaporized expanding gradually, internal layer shell 1 is moved upward to epicoele 12 tops under the pressure-acting of cavity of resorption working medium, steam in epicoele 12 is discharged epicoele 12 by the interface 14 at outer casing top, conduction oil is full of the residual volume of epicoele, adsorbent bed is by the heat-conducting oil in lumen wall and lumen 10, heat-pipe working medium 5 in heating internal layer shell, heat-pipe working medium 5 heat absorption evaporations, steam rises to internal layer shell top, by the heat-conducting oil in epicoele wall and epicoele 12, heat is reached to low-temperature cooling media, reach the object of cooling adsorbent bed, the cooling absorption of adsorbent bed.When cooling procedure, the duty of alternation formula of the present invention three-temperature-zone heat-pipe apparatus is the state of cooling.In this process, because the lower end of internal layer shell 1 is supported by lower sealing ring 8, cavity of resorption 7 is isolated with lumen 10 and epicoele 12, heat transmission can not occur between thermal source and adsorbent bed, thereby improved cooling effectiveness.
As known from the above, heat-pipe apparatus of the present invention is by the structural design of alternation formula three-temperature-zone, when heat-pipe apparatus during in heated condition internal layer shell move down and occupy lumen and cavity of resorption, there is not heat transmission by thermal source to adsorbent bed heating and with the low-temperature cooling media of epicoele; When heat pipe moves and occupies lumen and epicoele on internal layer shell during in the state of cooling, the heat of adsorbent bed is passed to low-temperature cooling media is cooling with thermal source cavity of resorption, heat transmission does not occur, so can effectively improve the heating and cooling efficiency of adsorbent bed.
