Description

A kind of micro-channel heat exchanger
Technical field:
The utility model is related to refrigeration technology field, is especially a kind of micro-channel heat exchanger.
Background technology:
Heat exchanger is the important component of progress heat conversion in refrigerator or refrigerator, and its structure directly affects refrigeration.It is existing Some wind cooling refrigerator condensers are wrapped in the combining structure on steel pipe using rotation wing formula condenser, ribbon spiral, and volume is larger, weight Amount is heavier, and processing technology is complicated, and surface needs electrophoresis to improve product antiseptic power, and it is big that refrigerant rushes fluence.Air cooling refrigerator evaporator is normal With full aluminum fin-stock tubular structure, typically using common aluminum pipe bending, and the different aluminium flake of density, this tube expansion on set outside aluminum pipe Structural thermal efficiency is low, and the exchange capability of heat for needed for reaching is had to the size for increasing core body, and space efficiency utilization is low.
In recent years, continuing to develop with technology, full aluminium micro-channel heat exchanger is high with small in volume, the coefficient of heat transfer, The advantages of high-efficiency environment friendly, is gradually applied in refrigerator.Micro-channel heat exchanger mainly include flat tube, fin, import tube assembly with Tube assembly is exported, flat tube is that several bending circular arcs and straight line form and fin, the structure are provided between snakelike shape, adjacent flat tube The heat exchanger of form is in refrigerator as evaporator in use, due to environment in refrigerator and flowing through between cooling agent inside flat tube The temperature difference is formed, dew liquid film can be produced on flat tube surface, water droplet can be also formed in the middle of fin when dew gathers together. If dew is discharged from flat tube and fin surface not in time, it is very low to add environment temperature, in the short period of time can be in flat tube Surface produces frost.And frosting greatly reduces the overall heat exchange efficiency of heat exchanger.The present invention provides a kind of new flat tube And fin, heat exchanger drainage problem can be effectively solved, heat exchanger energy efficiency is improved;Flat tube internal volume reduces, and reduces refrigerant and fills Fluence;The structure slotted using flat tube muscle effectively reduces heat exchanger space-consuming and weight.
Utility model content:
Technical problem to be solved in the utility model, which is to provide, a kind of can effectively solve the Thermal Performance of Micro Channels of drainage problem Device.
Technical solution of the present utility model is to provide a kind of micro-channel heat exchanger, including straight flat tube by single hole and Fin, the snake are provided between the snakelike flat tube that the bending circular arc flat tube of single hole is formed by connecting, the adjacent straight flat tube of snakelike flat tube Shape flat tube has multiple, and multiple coiled pipes are set up in parallel, one end connection inlet tube of each snakelike flat tube, the other end of snakelike flat tube Connection outlet pipe, sets spacer, the stream that refrigerant is set after inlet tube entrance according to spacer in inlet tube and outlet Road is flowed through after each snakelike flat tube flows out from outlet, is connected by connecting rib between adjacent snakelike flat tube, connection rib along Connection rib length direction is stamped with multiple water grooves excessively for being available for condensed water to pass through, correspondingly, the wing contacted with snakelike flat tube Piece crest portion and trough portion also offer the notch for being available for condensed water to pass through, and notch is corresponding with the water groove excessively of snakelike flat tube.
Using compared with prior art, the utility model has advantages below after above structure:Respectively in snakelike flat tube Water groove is crossed in punching press on connection rib, and notch is opened up on fin, and the condensed water for condensing in flat tube surface just can be along water excessively Groove and notch discharge, improve draining and defrost efficiency, and snakelike flat tube configuration can effectively reduce coolant injection amount, snakelike flat tube and Fin fluting reduces heat exchanger weight, reduces air wide pre. drop, so as to improve heat exchange efficiency.
Preferably, it is square structure to cross water groove and notch.
Preferably, fin is wavy windowing or not louvered fin.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 partial enlarged drawing.
Fig. 3 is the structural representation of fin.
Embodiment:
The utility model is described in further detail with reference to the accompanying drawings and detailed description:
As Figure 1-3, a kind of micro-channel heat exchanger, including the straight flat tube by single hole and the bending circular arc flat tube company of single hole Wavy fin fin 2 is installed, fin 2 is that aluminium foil leads between the snakelike flat tube 1 connect, the adjacent straight flat tube of snakelike flat tube Wavy windowing or non-fenestration that fin shaping is machined into are crossed, the snakelike flat tube 1 has multiple, and multiple coiled pipes are simultaneously Row are set, one end connection inlet tube 3 of each snakelike flat tube, the other end connection outlet pipe 4 of snakelike flat tube, in the He of inlet tube 3 Spacer is set in outlet 4, and one end closure of inlet tube 3 and outlet 4 has an end cap 5, refrigerant after inlet tube entrance according to The stream of spacer setting is flowed through after each snakelike flat tube to flow out from outlet, is connected by connecting rib 6 between adjacent snakelike flat tube Connect, connection rib 6 is stamped with multiple rectangular water grooves 7 excessively for being available for condensed water to pass through along connection rib length direction, Correspondingly, the fin crest portion and trough portion contacted with snakelike flat tube also offers the square notch 8 for being available for condensed water to pass through, groove Mouth 8 is corresponding with the water groove 7 excessively of snakelike flat tube so that condensed water can pass through.
In the present embodiment, the snakelike flat tube width of micro-channel heat exchanger is 10-100mm, hole count 3-30, flat tube thickness 1.5-10mm。
Only the utility model preferred embodiment is described above, but is not to be construed as the limit to claim System.Equivalent structure or equivalent flow conversion that every utilization the utility model specification and accompanying drawing content are done, are included in this Within the scope of patent protection of utility model.
