Abstract
The utility model relates to a microchannel cooling fin structure which comprises microchannel plates and cooling fins, multiple micro channels are formed in the microchannel plates, and the front end and the rear end of each microchannel plate are provided with pipelines communicated with the micro channels. The width of the cooling fins is larger than that of the microchannel plates, the cooling fins are provided with multiple slotted holes allowing the microchannel plates to penetrate through, the slotted holes are arranged evenly, and the sizes in the length direction and the width direction of each slotted hole are smaller than those of the corresponding micro channel. By the adoption of the structure, the microchannel plates with the micro channels can carry out separated heat dispassion on fluid to be cooled, heat dispassion effects can be improved through the inserted cooling fins, welding is not needed, manufacturing is facilitated, investment cost of production equipment is saved, and dismounting and maintenance are convenient.
Description
Technical field
The utility model relates to a kind of radiator, especially relates to a kind of microchannel heat radiating fin structure.
Background technology
Radiator mainly for by unnecessary dissipation of heat to air to reach the normal operation of machine, if the area that radiator contacts with air by fin dispels the heat, the larger radiating effect of fin area is better, yet in some small-sized machinery equipments, doing that fin should not be done is too much, current radiator normally welds fin on carrier pipe, due in small-sized machine, need to drop into high equipment, fin is in welding simultaneously, easily, by carrier pipe burn-through, cause leakage.And after long-time use, the fin that need to more renew is also inconvenient to change, use inconvenient.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of welding and microchannel heat radiating fin structure easy to use of not needing.
The technical scheme in the invention for solving the technical problem is: a kind of microchannel heat radiating fin structure, comprise microchannel sheet and fin, the inside of described microchannel sheet forms a plurality of passage aisles, and the rear and front end of described microchannel sheet is equipped with the pipeline being communicated with passage aisle; The width of described fin is greater than the width of microchannel sheet, offers a plurality of slotted eyes that pass for microchannel sheet on described fin, and described slotted eye is evenly distributed, and described slotted eye is long is less than corresponding microchannel length and cross direction size with wide both direction size.
Further concrete, described microchannel sheet and fin at right angle setting.
Further concrete, described microchannel sheet and fin form orthogonal network structure by a plurality of.
The beneficial effects of the utility model are: after having adopted said structure, the microchannel sheet that employing has passage aisle can finely separately dispel the heat the fluid of heat radiation, and improve radiating effect by the fin of pegging graft, and do not need to weld, do not need to drop into high equipment.Be easy to remove and repair.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is fractionation structural representation of the present utility model;
Fig. 3 is the structural representation before the processing of the utility model fin;
Fig. 4 is the structural representation after the processing of the utility model fin.
In figure: 1, microchannel sheet; 2, fin; 3, slotted eye; 4, pipeline.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is explained in detail.
A microchannel heat radiating fin structure, comprises microchannel sheet 1 and fin 2 as shown in Figure 1, Figure 2, Figure 3 and Figure 4, and the inside of described microchannel sheet 1 forms a plurality of passage aisles, and the rear and front end of described microchannel sheet 1 is equipped with the pipeline 4 being communicated with passage aisle; The width of described fin 2 is greater than the width of microchannel sheet 1, offers a plurality of slotted eyes 3 that pass for microchannel sheet 1 on described fin 2, and described slotted eye 3 is evenly distributed; Described microchannel sheet 1 and fin 2 at right angle settings; Described microchannel sheet 1 and fin 2 form orthogonal network structure by a plurality of.
When installing, first at fin 2, go out some uniform slotted eyes 3, slotted eye 3 sizes are less than fin 2 sizes, microchannel sheet 1 is inserted in slotted eye 3, then insert successively microchannel sheet 1 and fin 2, complete installation, do not need welding, simple in structure, easy to operate, saving welding equipment easy to maintenance drops into, and radiating effect is more remarkable.
It is emphasized that, it is more than better implementation column of the present utility model, not the utility model is done to any type of restriction in appearance, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
