Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1 to Figure 3, this structure improved heat exchanger comprises deflector, and described deflector is repeatedly folded to form the equal tabs of some width 100, and two tabs 100 of head end and end are connected to form radiating tube 110.
Above-mentioned deflector forms multiple tabs 100 through repeatedly folding, on deflector, head end is connected with the tabs 100 of end and deflector is joined end to end and forms radiating tube 110, the shape of radiating tube 110 cylindrically thus improve the rigidity of heat exchanger, avoid heat exchanger tabs 100 in the process of work bend and affect the normal work of heat exchanger, tabs 100 forms by deflector is directly folding the sealing that ensure that radiating tube 110 simultaneously, avoid and to need adhesion agent between adjacent two tabs 100 or increase pad and connect, the long-time use of heat exchanger causes adhesion agent inefficacy to make the junction between adjacent two tabs 100 rupture or cause occurring leak point at weld, thus have impact on the radiating effect of heat exchanger, tabs 100 replaces the setting of smooth heat radiation plane to expand the area of dissipation of heat exchanger simultaneously, improve radiating effect.
The first groove 200 is formed between the outer surface of adjacent two tabs 100, the second groove 300 is formed with between tabs 100 and the inner surface of another adjacent flaps 100 of this tabs 100 arbitrarily in adjacent two tabs 100, any first groove 200 is arranged between adjacent two the second grooves 300, first groove 200 and the second groove 300 are provided with separator, the setting of separator ensure that the spacing between adjacent two tabs 100, avoid spacing between two adjacent tabs 100 too small and reduce the circulation efficiency of heat exchanger, have impact on the radiating effect of heat exchanger.
Preferably, above-mentioned separator comprises the spring be arranged between adjacent two tabs 100, spring comprises the first spring 210 be arranged in the first groove 200 and the second spring 310 be arranged in the second groove 300, the setting of spring ensure that to there is gap between adjacent two tabs 100, simultaneously the gauge of wire of spring is less thus take up room little, avoids the circulation efficiency that spring affects air-flow in groove.
Further, the spacing of the first groove 200 is equal with the spacing of the second groove 300, thus the number of turns being installed on the first groove 200 and the second groove 300 inner spring is respectively equal, preferably the number of turns is 1 circle, but the number of turns of spring is not limited to 1 circle, the first groove 200 that spacing is equal and the second groove 300 make the circulation of the air-flow of heat exchanger within the unit interval equal, ensure that the air flow energy of the first groove 200 and the second groove 300 obtains sufficient heat exchange, and the first groove 200 is equal with 1 spacing of enclosing of spring with the spacing of the second groove 300, when the diameter of radiating tube 110 is constant, tabs 100 quantity is added while ensure that the circulation of groove, thus improve the area of dissipation of radiating tube 110, improve the radiating effect of heat exchanger.
As another kind of situation of the present utility model, the spacing of the first groove 200 and the spacing of the second groove 300 are not etc. and the spacing of the first groove 200 is greater than the spacing of the second groove 300, thus the number of turns being installed on the first spring 210 in the first groove 200 is greater than the number of turns of the second spring 310 be installed in the second groove 300, and what import at the first groove 200 and the second groove 300 is cold airflow and thermal current respectively, thus the circulation of cold airflow in the unit interval is greater than the circulation of thermal current, make the thermal current of unit volume can carry out heat exchange with the cold airflow of multiple unit volume, thus improve the radiating efficiency of heat exchanger.
The diameter at radiating tube 110 two ends in axial direction reduces gradually from inside to outside respectively or increases, thus be arranged at the air inlet at radiating tube 110 two ends and air outlet forms horn mouth or bell, when the two ends of radiating tube 110 form horn mouth, improve air intake and the air-supply efficiency of radiating tube 110, when the two ends of radiating tube 110 form bell, the air-flow of radiating tube 110 air inlet and air outlet can be concentrated, thus improve the circulation efficiency of radiating tube 110 and improve the air supplying distance of radiating tube 110.
Preferably, the diameter of radiating tube 110 in axial direction reduces gradually or increases, thus make one end of radiating tube 110 form horn mouth, the other end forms bell, thus there are following 4 kinds of situations in the two ends of radiating tube 110: the two ends of radiating tube 110 are horn mouth, the two ends of radiating tube 110 are bell, radiating tube 110 air inlet one end is horn mouth and air outlet one end is bell, radiating tube 110 air inlet one end is bell and air outlet one end is horn mouth, this heat exchanger can select the shape at radiating tube 110 two ends according to actual needs, thus improve the service efficiency of radiator 110.
The two ends of radiating tube 110 are provided with ring-type fixing plate 410, the first skirt section 420 and the second skirt section 430 has in axial direction been extended to form respectively at the madial wall of ring-type fixing plate 410 and lateral wall, cannelure is formed between the first skirt section 420 and the second skirt section 430, above-mentioned radiating tube 110 is arranged in cannelure, at this heat exchanger in the process of transporting or use, radiating tube 110 is made to be positioned at cannelure all the time, avoid tabs 100 be subjected to displacement and affect the air-flow conducting efficiency of radiating tube 110, ensure that the steadiness that radiating tube 110 is installed simultaneously.
Further, thermal current imports and is derived by the lower end of radiating tube 110 in the second groove 300 of radiating tube 110 upper end, in the first groove 200 of radiating tube 110 lower end, import cold airflow and derive from the upper end of radiating tube 110, thus cold airflow can form relative flowing with thermal current, in the process that air-flow flows relatively, cold airflow and thermal current can form heat exchange on tabs 100 surface, the temperature of the thermal current of the second groove 300 derivation from lower end and the temperature close imported from the first groove 200 of lower end, the cold airflow imported with the first groove 200 of reason radiating tube 110 lower end is when deriving and the temperature close of thermal current of importing, and due to temperature close air-flow between heat conduction efficiency high, avoid cold airflow and thermal current co-flow and cause both temperature difference large and reduce heat conduction efficiency, thus the air-flow of flowing relatively improves radiating effect and the radiating efficiency of heat exchanger, the deflector that the setting of tabs 100 is compared to surfacing smooth simultaneously adds area of dissipation, the contact area of cold airflow or thermal current and deflector is increased, thus improve the radiating effect of heat exchanger.
Further, be provided with in radiating tube 110 and be connected with connecting portion and the axial length fixed network 500 equal with the axial length of tabs 100, thus fixed network 500 is also positioned at cannelure, fixed network 500 the air-flow that can be filtered through in radiating tube 110 is set, avoid and be entrained in impurity in air-flow and cause damage by heat exchanger to the equipment after being positioned at heat exchanger, the setting of fixed network 500 simultaneously ensure that the steadiness of the installation of radiating tube 110.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
