Description
Technical field:
The utility model relates to a kind of heat pipe level of isolation pallet high-efficiency evaporator.Belong to technical field of refrigerating devices.
Background technology:
Evaporimeter in the absorption type system is difficult to explosive evaporation takes place when being working medium with low pressure vaporized refrigerants such as water, does not generally adopt the immersion evaporimeter.The evaporimeter that is adopted in the absorption type system mainly contains fountain and immersion.The form of heat exchanger has shell-and-tube, plate-fin and other evaporating surfaces to take the heat exchanger of heat conduction reinforced technology.For single bed system, the heat exchanger of existing above-mentioned form can be competent at the effect of evaporation and liquid collecting well, but in many continuous systems, if continue to adopt above-mentioned simple form, just need install vacuum valve (flapper valve, magnetic valve etc.) or chilled water system transfer valve additional, this will reduce the reliability and the practicality of system greatly.And be difficult to avoid the cold and hot refrigerating capacity of changing when switching of evaporimeter to lose.Find by literature search, the people such as KashiwagiT. of the ChuaH.T. of Singapore and Japan are at International Journal of Refrigeration (international refrigeration magazine), introduced a kind of single evaporator in " Modeling the performance of two-bed; silica gal-wateradsorption chillers " (double bed adsorption refrigerating device performance simulation) literary composition of delivering on 22 (1999), the double bed adsorption refrigeration system of single condenser, four vacuum barrier valves have been adopted in this system, use U type pipe to realize the isolation of condensation process and evaporimeter, avoided well betiding the refrigerating capacity loss that evaporimeter brings because of condensation, and realized the compact design requirement of whole unit, but to requiring all very high in the design and fabrication technology of the vacuum barrier valve that hangs down the pressure reduction keying, vacuum valve can't be changed, to the reliability requirement height, and the existence of the blowdown of a safety valve of vacuum valve has also brought unavoidable refrigerating capacity loss.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, a kind of heat pipe level of isolation pallet high-efficiency evaporator is provided, when being used for many adsorption refrigeration systems, thereby make it pass through condensation and the isolation realization desorb condensation side isolator of evaporation and the heat isolation between the evaporimeter of bottom that the heat pipe isolation technology is realized cold-producing medium.
The purpose of this utility model is achieved in that a kind of heat pipe level of isolation pallet high-efficiency evaporator, comprise dividing plate, cylindrical shell, isolator shrouding, isolator capillary evaporation enhanced tube, isolator dividing plate, liquid distributor, evaporator pipe sheet, evaporimeter capillary evaporation enhanced tube and isolator liquid trap, described dividing plate, isolator shrouding, isolator capillary evaporation enhanced tube, isolator dividing plate, liquid distributor and isolator liquid trap all place the cylindrical shell internal upper part left and right sides, the isolator of two mirror image symmetries about formation; Described evaporator pipe sheet and evaporimeter capillary evaporation enhanced tube all place bottom in the cylindrical shell, constitute evaporimeter with cylindrical shell; Above-mentioned evaporimeter and isolator constitute heat pipe level of isolation pallet high-efficiency evaporator, left and right isolator capillary evaporation enhanced tube links to each other with the isolator tube sheet, the isolator tube sheet links to each other with the isolator shrouding, isolator is fixed on the top of cylindrical shell, left and right sides isolator symmetric arrangement, being the refrigerant vapour passage between isolator and the dividing plate, is the work medium for heat pipe steam channel between the tube side of isolator and the cylindrical shell, and evaporimeter is fixed in the cylindrical shell bottom.
(tube side) is cold water in the evaporimeter capillary evaporation intensify heat transfer pipe, and pipe outer (shell side) is a work medium for heat pipe; The capillary evaporation enhanced tube of isolator outer (shell side) is a cold-producing medium, and (tube side) is work medium for heat pipe in the pipe.The capillary evaporation enhanced tube adopts the surface heat transfer reinforcement technique, porous media or spiral are arranged on its tube-surface, the capillary evaporation intensify heat transfer pipe partly is immersed in the cold-producing medium, makes the cold-producing medium can evenly cloth liquid and evaporation on whole tube-surface by the capillarity of porous media or spiral.The working media of this heat pipe adopts the liquid of low boiling, low freezing point, as methyl alcohol, ethanol, water etc.
During work, work medium for heat pipe is explosive evaporation generation steam outside the capillary evaporation intensify heat transfer pipe of evaporimeter at first, owing to the metal temperature of isolator one side of adsorbing evaporation is low, it is the minimum part of temperature in the whole evaporimeter, the steam that in the evaporimeter each layer capillary evaporation enhanced tube produces rises and (in the capillary evaporation intensify heat transfer pipe of isolator) condensation on the lower metal surface of temperature, and condensate liquid is dirty in the middle of the pallet of upper strata, bottom heat-transfer pipe by the isolator liquid trap under the air-flow effect promotes; And the metal temperature of isolator one side that carries out the desorb liquid collecting is higher, it is the highest part of temperature in the whole evaporimeter, be in the top of heat pipe again, therefore, this side isolator can not followed Heat Transfer of Heat Pipe on Heat Pipe working medium generation heat exchange, and the isolator temperature of this side just can not be low excessively, thereby guaranteed that most condensation processes occur in condenser, realize the isolation of isolator evaporation and liquid collecting, reduced refrigerating loss.
The unidirectional heat-transfer character of gravity assisted heat pipe of utilizing the utility model realized not working isolator in isolator and the work and the isolation between the evaporimeter make cold water need not switch the output that just can realize continuous cold.When being used for many adsorption refrigeration systems, can not install any switch valve additional in cold water one side, improved the operational reliability of absorption refrigeration unit.Simultaneously, the resident cold water owing in the evaporimeter that exists in the multi-evaporator absorbing refrigeration system of having avoided needing cold water to switch makes too much condensation process occur in the refrigerating capacity loss that evaporimeter brings.Problem and the single evaporator absorbing refrigeration system of having avoided the unit operation reliability that caused by too much vacuum switch valve in the single evaporator absorbing refrigeration system to reduce must use cryogenic fluid pump and increase the device fabrication cost when starting.In addition, the capillary ability of also utilizing capillary evaporation augmentation of heat transfer tube-surface evenly on the evaporating surface that is distributed to the capillary evaporation pipe, has solved the uniformity of low discharge condensate liquid cloth liquid to condensate liquid.
