Description
Affiliated technical field
The present invention relates to a kind of refrigerating plant of refrigerator, be specifically related to a kind of evaporator of refrigerator, more particularly, relate to a kind of tube-sheet type evaporator of refrigerator.
Background technology
Evaporator of refrigerator divides two kinds usually, and a kind of is the tube-sheet type evaporator of refrigerator, and another kind is the inflation type evaporator of refrigerator.Wherein the tube-sheet type evaporator of refrigerator generally includes heat-conducting plate and coil pipe, and coil pipe is fixed on the lower surface of heat-conducting plate.The fixed form of above-mentioned coil pipe is generally the word heat-conducting plate and stamps out claw downwards, and coil pipe is installed on the lower surface that in the described claw coil pipe is fixed on heat-conducting plate.During the refrigerator refrigeration, evaporimeter conducts low temperature to heat-conducting plate by coil pipe, and heat-conducting plate is scattered in chamber between refrigerator with low temperature.Above-mentioned evaporator of refrigerator in use, when refrigerator freezes, easily frosting between coil pipe and heat-conducting plate, long-term use frost layer expands and causes claw fixing insecure, produce bigger slit between the coil pipe of evaporimeter and heat-conducting plate, reduced the heat conduction efficiency between coil pipe and heat-conducting plate, the refrigerator refrigeration is affected, for solving the shortcoming that original refrigerator tube-sheet type evaporimeter exists, invented new technical scheme in the refrigerator manufacturing that has to solve the technical problem that prior art exists, disclose a kind of sandwich-type plate, pipe evaporator as Chinese patent 00263748.It is made up of aluminum plate, aluminum pipe spare, resilient sleeve, lid and plastics clamp; Cover and be provided with the type groove, resilient sleeve is equipped with in the bottom of type groove, and aluminum pipe spare is close in the type groove that resilient sleeve is installed in lid, and aluminum plate is contained in the one side of the type that the is provided with groove of lid, respectively be provided with corresponding slotted eye on lid and the aluminum plate, the plastics clamp of fixed cap and aluminum plate is housed in the described slotted eye.Although the disclosed technology contents of above-mentioned patent document can make heat-conducting plate contact with coil pipe closely, with the fastener complex structure of evaporimeter heat-conducting plate and coil pipe, the area of dissipation of heat-conducting plate is limited simultaneously, and heat conduction efficiency is low, and the refrigerating efficiency of refrigerator is low.。
In sum, existing tube-sheet type evaporator of refrigerator is because there is following deficiency in the defective of structure:
1, owing in the chamber multilayer evaporimeter is set usually between same refrigerator, because evaporimeter is a tabular, evaporimeter has hindered the cross-ventilation of evaporimeter insulating space, and the non-uniform temperature of chamber has influenced refrigeration between refrigerator.
2, because the coil pipe of evaporimeter is fixed on the flat heat-conducting plate by claw, and heat-conducting plate is little with the coil pipe contact area that is generally tubular, and heat conduction efficiency is low, refrigerating speed is slow.
3, heat-conducting plate is a tabular, and heat-conducting area is little, influences refrigeration equally.
4, in process of refrigerastion, cause claw to expand owing to freeze easily between claw and coil pipe, fixing insecure the making between coil pipe and the heat-conducting plate of coil pipe produces the slit, influenced the heat transmission between coil pipe and the heat-conducting plate, and refrigeration reduces; The perhaps fixture structure complexity of coil pipe and heat-conducting plate, the production and processing trouble.
Summary of the invention
The present invention has overcome the shortcoming that existing tube-sheet type evaporator of refrigerator exists, a kind of novel tube-sheet type evaporator of refrigerator is provided, this evaporimeter can make the air free convection in the different evaporators space at interval in the refrigerator same chamber, uniformity of temperature profile between refrigerator in the chamber, place the food refrigeration of diverse location identical, refrigeration in time.
The present invention provides a kind of tube-sheet type evaporator of refrigerator simultaneously, and the heat-conducting plate heat-conducting area of this evaporimeter is big, heat conduction efficiency height, good refrigeration effect.And further the contact area of heat-conducting plate and coil pipe is big, the heat conduction efficiency height between heat-conducting plate and coil pipe, and refrigeration further improves.
The present invention further provides a kind of tube-sheet type evaporator of refrigerator, fixation between the heat-conducting plate of this evaporimeter and coil pipe, fixed structure is simple, and evaporimeter uses for a long time, can not produce the slit between heat-conducting plate and coil pipe, and heat-conducting effect is stable, and the refrigerator refrigeration performance is stable.
Be the technical purpose that realizes that above-mentioned novel tube-sheet type evaporator of refrigerator will reach, the present invention has adopted following technical proposals.
