Heat pipe is made up of shell, imbibition core and end cap, fills in evacuated pipe with suitable working solution, mounts the imbibition core near tube wall, again its two ends are shut heat pipe.Heat pipe be evaporimeter be again condenser, as shown in Figure 1.From an end of hot-fluid heat absorption is evaporator section, carburation by evaporation behind the working medium absorption latent heat, flowing to cold fluid one end is condensation segment heat release liquefaction, and rely on the capillary force effect to flow back to evaporator section, automatically finish circulation, heat exchange of heat pipe is fitted together by these single heat pipe collection exactly, the middle device that evaporator section and condensation segment is separated with dividing plate, heat exchange of heat pipe need not external impetus and impels working fluid cycles, and this is its major advantage.Heat pipe is broadly divided into three kinds of different situations: monoblock type imbibition core heat pipe, monoblock type thermal siphon (gravity assisted heat pipe), separate heat pipe by the difference of version.
Monoblock type imbibition core heat pipe is the general type of heat pipe, and the general heat pipe of saying just is meant this heat pipe, and lime set refluxes by the capillarity of imbibition core, does not rely on the effect of gravitational field, also can work its work characteristics that Here it is under weightless situation.Imbibition core heat exchange of heat pipe can be realized reclaiming cold summer and reclaiming heat winter as energy recycle device simultaneously.Need not to change airflow direction and pipe arrangement.
The characteristics of gravity assisted heat pipe are: conducting heat has one-way, lime set is by gravity reflux, condensation segment must place on the evaporator section, because it does not have the imbibition core, structure is simpler, and is easy to manufacture, and service behaviour is not less than imbibition core heat pipe, the heat application of air conditioner ventilation is a Lowlevel thermal energy, and employed heat pipe mostly is the gravity type Cryo Heat Tube.Therefore, heat exchange of heat pipe is as heat recovery system or the use of cold recovery system the time, and all genus may preferentially adopt the gravity type heat pipe heat exchanger.
Separate heat pipe is used for the air-conditioning system energy of exhaust air and reclaims, utilize the characteristics of separate heat pipe cleverly, the complex pipeline design that can avoid big flow gas transfer to cause, can effectively reclaim the low taste energy in the air draft again, reduce the refrigeration/heat of refrigeration/hot equipment, thereby reach purpose of energy saving.Simultaneously, the pipe fitting that separate heat pipe is ganged up mutually is more, in case revealing appears in the somewhere, will cause the forfeiture of whole row's assembly or whole heat exchanger function, and these all design and use and need take seriously.
The utility model content
The purpose of this utility model provides a kind of novel indirect evaporation cooler that utilizes heat exchange of heat pipe, cutting down the consumption of energy, and improves the efficient that the energy of air-conditioning system reclaims.
A kind of novel indirect evaporation cooler of the utility model, comprise heat exchange of heat pipe, described heat exchange of heat pipe by single heat pipe and arrange in a row the dress form, wherein an end is an evaporator section, the other end is a condensation segment, and the centre, is characterized in that separately as the adiabatic section with dividing plate: the condensation segment at described heat exchange of heat pipe coats absorbent material, and adding a liquid distribution, described liquid distribution is to the absorbent material spray water.
Technique scheme can further be improved to: the evaporator section at described heat exchange of heat pipe is equipped with fin structure (6).The idle call heat exchange of heat pipe belongs to gas gas heat exchange of heat pipe, often takes to add at pipe the method for fin for the coefficient of heat transfer that improves gas, so just can improve exchange capability of heat greatly, thereby reduce required heat pipe number.
In the technique scheme, described absorbent material is preferred: sepiolite or zeolite.
A kind of novel indirect evaporation cooler of the utility model, the energy that this new heat pipe indirect evaporation cooler consumed only is the energy consumption of blower fan and water circulating pump, compare with the conventional mechanical refrigeration, it is a kind of air-cooling apparatus that need not auxiliary power, be again a kind of good energy saver simultaneously, come the new wind of preheating by the heat that uses this device can realize reclaiming winter in the air draft, the cold that reclaims summer in the air draft comes the new wind of precooling, is a kind of new and effective heat transmission equipment.
