Abstract
The invention discloses a finned-tube evaporator, and belongs to the finned-tube evaporator for various types of freezers. The finned-tube evaporator is characterized by comprising an evaporating tube, wherein fins are longitudinally distributed outside the evaporating tube; and defrosting tubes are arranged on the fins. The finned-tube evaporator consists of the fins, the evaporation tube and the defrosting tubes which are formed by integrally extruding; and the functions of automatic heating medium defrosting, safety and reliability of the evaporator are realized. According to the finned-tube evaporator, a heating medium defrosting method is adopted, and according to the heating medium defrosting method, a heating medium (a heat transfer fluid) used for defrosting is intruded into the defrosting tubes, and heat is transferred to cold row of fins by utilizing the convective heat release of the heating medium in the tubes, so that a frost layer is defrosted.
Description
Technical field
The present invention relates to all kinds of freezer calandria evaporators, specifically a kind of ribbed pipe type evaporator.
Background technology
Along with the progress of Refrigeration Technique and the development of aluminium calendering process technology, aluminium alloy cold type pipe is used widely in refrigeration system.Aluminium alloy ribbed pipe type evaporator (hereinafter to be referred as " aluminium row ") is one of cold type pipe of commonly using, has that lightweight, heat transfer coefficient is large, the heat transfer efficiency advantages of higher, is one of desirable evaporimeter of all kinds of freezers.Along with aluminium row's popularization and application, aluminium row defrosting problem highlights.Aluminium row adopts the electric heater defrosting method in recent years, is about to heating wire and is installed in the Baltimore groove of evaporator fin, and at the U-shaped drip tray of fin grafting, solved preferably aluminium row's automatic defrosting problem, and draining is smooth and easy, and is safe and reliable, and certain occupation rate is arranged in market.But the embedded installation of heating wire and cold type, the thermal contact resistance that causes can not be ignored.In the simultaneously use procedure, the heating wire that heating wire comes off and careless manipulation causes is pulled apart phenomenon, and the maintenance issues that causes all is the very important defective of electric heater defrosting method.
Summary of the invention
In order to overcome the deficiencies in the prior art, the objective of the invention is to propose a kind of ribbed pipe type evaporator that adopts the heating agent defrost method on the basis of existing product.
The technical scheme that technical solution problem of the present invention adopts is: a kind of ribbed pipe type evaporator is characterized in that: an evaporation tube is arranged, and the outside of evaporation tube vertically is distributed with fin, is provided with defrosing pipe on the fin.
The fin that the outside of described evaporation tube distributes has 1～5.
Be provided with defrosting pipe on the described fin and have 1～3.
Be connected with the heating agent (heat transport fluid) that defrosting is used in the described defrosting pipe.
The present invention is comprised of fin, evaporation tube, the defrosing pipe of monolithic extruded moulding, can realize the automatic heating agent defrosting of evaporimeter, safe and reliable function.The present invention adopts the heating agent defrost method, exactly the heating agent (heat transport fluid) that defrosting is used passes into defrosing pipe, utilizes heating agent convection heat transfer in pipe, heat is delivered to the cold type fin, thereby melts the method for taking off frost layer.
Effect of the present invention is:
(1) defrosing pipe and cold type adopt monolithic extruded moulding, there is not thermal contact resistance between defrosing pipe and the cold type, heating agent passes into defrosing pipe, utilize heating agent convection heat transfer in pipe, heat is delivered to the cold type fin, from frost layer bottom defrosting, the frost layer bottom is at first melted, frost layer comes off under action of gravitation, improves defrosting efficient.
(2) heating agent self-organizing system, thermal source can be suited measures to local conditions, and adopts the inferior grade thermals source such as used heat, system condensing heat, seawater.Heat medium system can adopt circulating, but also straight-line etc., and system is flexible, according to the actual requirements design alternative.
(3) increase heat transfer area.When refrigeration system was moved, defrosing pipe was as the composition of fin, and the inned coefficient of evaporimeter and rib efficient all improve; In heating agent defrosting process, fin is as the defrosting heat carrier, and the heat of heating agent is delivered on the whole cold type, and defrosting is even, and is without the dead angle, effective.
(4) safe and reliable.Because heat medium system and refrigeration system are relatively independent, the sealing of heat medium system etc. does not affect refrigeration system.Compare with electrothermal defrosting system, the heat transport fluid that heat medium system adopts, even leakage etc. do not affect the use of environment and total system, defrosting system is safe and reliable to operation.
Description of drawings
Below in conjunction with drawings and Examples the present invention is conducted further description.
Fig. 1 is the topology view that the present invention is distributed with two fins.
Fig. 2 is the topology view that the present invention is distributed with three fins.
01 fin among the figure, 02 defrosing pipe, 03 evaporation tube.
