Abstract
The utility model discloses a frostless refrigerator is with little channel evaporator, including import pipe, outlet pipe, installing support and heat exchange core, heat exchange core has the multilayer, and every layer of heat exchange core includes U -shaped micro channel flat tube, and micro channel flat tube's the outside is equipped with the sideboard respectively, and micro channel flat tube's inboard is equipped with the reinforcing plate, and the centre gripping has radiating fin between sideboard and the micro channel flat tube lateral surface, is equipped with radiating fin between reinforcing plate and micro channel flat tube's the medial surface. This frostless refrigerator is with little channel evaporator compact structure, the installation of being convenient for, heat exchange efficiency is high moreover.
Description
Technical field:
The utility model relates to a kind of evaporimeter, is specifically a kind of frost-free refrigerator micro-channel evaporator.
Background technology:
In refrigeration systems, the size of evaporator evaporation area and version directly affects refrigerating capacity and the refrigerating speed of system, finally affect the energy consumption of refrigerator.In order to solve the ubiquitous inner frosting problem of general refrigerator, frost-free refrigerator arises at the historic moment; Full aluminum fin-stock tubular type commonly used by existing frost-free refrigerator evaporimeter, the common aluminum pipe bending of general employing, and overlaps the different aluminium flake of density outward at aluminum pipe.This structure Problems existing: aluminum pipe and aluminium flake adopt lacing film expand tube structure, and heat transfer efficiency is very low; Aluminum fin-stock tubular structure is not a kind of radiating mode efficiently, and in order to reach required ability, have to increase the size of core body, space availability ratio is low.
Utility model content:
Technical problem to be solved in the utility model is, provides the frost-free refrigerator micro-channel evaporator that a kind of compact conformation, volume are little, heat exchange efficiency is high.
Technical solution of the present utility model is, a kind of frost-free refrigerator micro-channel evaporator is provided, comprise inlet tube, outlet, mounting bracket and heat exchange core body, heat exchange core body has multilayer, every layer of heat exchange core body comprises U-shaped micro-channel flat, and the outside of micro-channel flat is respectively equipped with side plate, and the inner side of micro-channel flat is provided with stiffener, be clamped with radiating fin between side plate and micro-channel flat lateral surface, between stiffener and the medial surface of micro-channel flat, be provided with radiating fin.
To adopt after above structure compared with prior art, the utility model has the following advantages: heat exchange core body adopts U-shaped micro-channel flat, utilizes the effect of microchannel dimensional effect in gas liquid two-phase flow and phase-change heat transfer rule, improves evaporator heat exchange efficiency; Reduce coolant injection amount simultaneously, establish radiating fin between flat tube and side plate and stiffener, can more compact structure be made, manufacture craft is simple, enhance productivity, and side plate and stiffener can improve core body intensity, reduce the damage risk in transport, installation process.
As preferably, every layer of heat exchange core body is horizontally set on mounting bracket from top to bottom successively, is parallel to each other between heat exchange core body.
Further, hot fin is any one in Rectangle Fin Radiator, trapezoidal radiating fin and triangle radiating fin.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of heat exchange core body.
Detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As depicted in figs. 1 and 2, a kind of frost-free refrigerator micro-channel evaporator, comprise inlet tube 1, outlet 2, mounting bracket 3 and heat exchange core body 4, heat exchange core body 4 has multilayer, every layer of heat exchange core body from top to bottom successively level be arranged on mounting bracket, be parallel to each other between heat exchange core body 4, every layer of heat exchange core body comprises U-shaped micro-channel flat 5, the outside of micro-channel flat is respectively equipped with side plate 6, the inner side of micro-channel flat is provided with stiffener 7, Rectangle Fin Radiator 8 is clamped with between side plate 6 and micro-channel flat lateral surface, be provided with Rectangle Fin Radiator 8 equally between stiffener 7 and the medial surface of micro-channel flat, micro-channel flat, side plate, stiffener and Rectangle Fin Radiator are welded together by soldering oven, so that carrying and installation.
Below be only described with regard to the utility model preferred embodiment, but can not be interpreted as it is limitations on claims.Every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion, as changed radiating fin into wavy fin, include within scope of patent protection of the present utility model.
