Abstract
The utility model discloses a finned tube type evaporator, belonging to the calaidria-type evaporator for various types of refrigeration houses. The finned tube type evaporator is characterized in that an evaporating tube is arranged; fins are longitudinally distributed at the outer side of the evaporating tube; and a defrosting tube is arranged on each fin. The finned tube type evaporator comprises fins which are obtained by integral extrusion forming, the evaporating tube and the defrosting tubes, so that the evaporator can automatically defrost by a heating medium, and the functions of safety and reliability are achieved. The finned tube type evaporator adopts a heating medium defrosting method; the method is realized by the following steps: the heating medium (heat transfer fluid) for defrosting is fed into the defrosting tube; as the heating medium releases heat convectively in the tube, the heat is transferred to the cooling row fins, therefore frost layers can be defrosted.
Description
Technical field
The utility model relates to all kinds of freezers and uses calandria evaporator, a kind of specifically ribbed pipe type evaporator.
Background technology
Along with the progress of Refrigeration Technique and the development of aluminium rolling processing 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 using always, has that in light weight, heat transfer coefficient is big, 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, be about to heating wire and be installed in the Baltimore groove of evaporator fin, and on fin grafting U type drip tray, solved aluminium row's automatic defrosting problem preferably, draining is smooth and easy, and is safe and reliable, and certain occupation rate is arranged on market.But the embedded installation of heating wire and cold type, the thermal contact resistance that causes can not be ignored.In the use simultaneously, 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.
The utility model content
In order to overcome the deficiency of prior art, the purpose of the utility model is on the basis of existing product, to propose a kind of ribbed pipe type evaporator that adopts the heating agent defrost method.
The technical scheme that the utility model technical solution problem is adopted 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, and fin is provided with defrosing pipe.
The fin that the outside of described evaporation tube distributes has 1～5.
Described fin is provided with defrosting pipe has 1～3.
Be connected with the heating agent (heat transport fluid) that defrosting is used in the described defrosting pipe.
The utility model is made up 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 utility model adopts the heating agent defrost method, exactly the heating agent (heat transport fluid) that defrosting is used feeds 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 the frost layer.
The effect of the utility model is:
(1) defrosing pipe and cold type adopt monolithic extruded moulding, do not have thermal contact resistance between defrosing pipe and the cold type, and heating agent feeds defrosing pipe; Utilize heating agent convection heat transfer in pipe; Heat is delivered to the cold type fin,, frost layer bottom is at first melted from the bottom defrosting of frost layer; The frost layer comes off under the effect of gravity, improves defrosting efficient.
(2) heating agent self-organizing system, thermal source can be suited measures to local conditions, and adopts inferior grade thermals source such as used heat, system condensing heat, seawater.The heating agent 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 no dead angle is effective.
(4) safe and reliable.Because heating agent system and refrigeration system are relatively independent, the sealing of heating agent system etc. does not influence refrigeration system.Compare with electrothermal defrosting system, the heat transport fluid that the heating agent system adopts, even leakage etc. do not influence the use of environment and total system, defrosting system is safe and reliable to operation.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is the topology view that the utility model is distributed with two fins.
Fig. 2 is the topology view that the utility model is distributed with three fins.
01 fin among the figure, 02 defrosing pipe, 03 evaporation tube.
