Description

Direct cooling refrigerator flat tube slice penetrating type mini channel evaporimeter
Technical field
The utility model relates to a kind of technology of field of heat exchange, specifically a kind of flat tube slice penetrating type mini channel evaporimeter for direct cooling refrigerator.
Background technology
The enhancing of recent domestic refrigeration industry energy-conserving and environment-protective consciousness, the application of micro-channel heat exchanger in refrigeration industry more and more receives the concern of people.Evaporimeter is as the important component part of refrigerator refrigeration system, and the raising of its performance is very helpful for the raising tool of refrigerator whole system performance.Develop efficient evaporator of refrigerator, not only be related to the overall operation performance of refrigerator, also be related to the manufacturing cost of refrigerator, development technology performance be good, refrigerator heat exchanger that heat transfer efficiency is high, rational in infrastructure, refrigerator Energy Efficiency Ratio can be improved, reduce manufacturing cost, increase usage space.
Micro-channel heat exchanger is the new type heat exchanger utilizing microchannel enhanced heat exchange theory to realize high efficient heat exchanging performance, relative to traditional copper pipe plate fin heat exchanger, has energy-conservation, environmental protection (reducing cold-producing medium, recyclable), lightweight, the advantages such as low cost.The channel diameter of its heat exchange tubing is usually at 0.1 ~ 1mm, and adopt all-aluminium construction, more traditional copper pipe ?radiator heat-exchanger can improve systematic function 20%, reduces refrigerant charge 40%, and reduces product cost 10%.Its aluminium parts all adopts extruding, die casting, full-automatic assembling grade for high efficient technology, can realize large-scale production, is the main flow of current refrigeration industry heat exchanger development, therefore develops a refrigerator micro-channel evaporator and have very high practical value.
Through finding the retrieval of prior art, Chinese patent literature CN102121798A, open (bulletin) day 2011.07.13, disclose a kind of flat tube-fin heat exchanger with double-side vortex generator, comprise the flat tube along gas flow direction arrangement and the fin be enclosed within flat tube, described fin is provided with the hole of suit flat tube, and punching press two is distinguished to vortex generators upwards and two to downward vortex generators in the both sides up and down in each hole, and on fin, leave corresponding aperture; The leading edge point of first pair of vortex generators is upwards positioned at the front end tangent line in the hole of suit flat tube, and the leading edge point of second pair of vortex generators is upwards positioned at the intermediate vertical line in the hole of suit flat tube.But all flat tubes of the heat exchanger in this technology all connect and pass same heat exchanger fin, such design well can not be applied to the special refrigerator air duct of structure, and for the evaporator of refrigerator of frost related frequency, heat exchanger fin is made an entirety and is unfavorable for defrost draining.
Utility model content
The utility model is for prior art above shortcomings, a kind of direct cooling refrigerator flat tube slice penetrating type mini channel evaporimeter is proposed, utilize cold-producing medium phase transformation to improve radiating efficiency, utilize the easy bending of aluminium micro-channel flat simultaneously, increase the heat exchange area of evaporimeter; The utility model good effect of heat exchange, manufacture simple, flexible structure, defrost is convenient.
The utility model is achieved through the following technical solutions:
The utility model comprises: micro-channel flat and some rectangular radiators be arranged in micro-channel flat, wherein: parallel to each other and spacing is equal between rectangular radiator
Described rectangular radiator is provided with the through hole matched with the cross sectional shape of micro-channel flat, to make micro-channel flat axially across rectangular radiator.
Described micro-channel flat can need to carry out plane bent, bending times >=1 according to refrigerator air duct size and actual heat exchange area, and the interval between the micro-channel flat be parallel to each other after bending adjusts according to air channel structure size.
Described plane bent refers to: after bending, all micro-channel flat are all in the same plane.
Described micro-channel flat width is 10 ?40mm, and thickness is 1 ?3mm, flat tube hole count 5 ?40.
Described rectangular radiator can perpendicular to horizontal plane, also can with horizontal plane alternating inclinations, increase turbulent flow reinforced heat exchange.
Can with horizontal plane or in an acute angle during described evaporimeter integral installation.
Described micro-channel flat, rectangular radiator all adopt aluminium material.
Technique effect
Compared with prior art, the structure of the utility model particular design contributes to the coefficient of heat transfer improving heat exchanger, and refrigerant charge is few, and tubing uses few, and processing technology is simple, easy to assembly, can be used to alternative conventional refrigerator evaporimeter.
