Abstract

The utility model provides a high -efficient combination cooling tube mainly includes fin, cooling tube, the fin sets up in the cooling tube, the interval is equipped with the swell of evagination on the cooling tube. The utility model provides a current cooler structure complicated, heat transfer area is little, air current turbulent flow effect subalternation shortcoming has further increased the heat transfer area of fluid side, improves air current turbulent flow effect, makes the heat transfer capacity of cooling tube promoted energetically.

Description

A kind of efficient combination cooling tube
Technical field
The utility model relates to gas recirculation system cooler technical field, particularly a kind of efficient combination cooler.
Background technology
At present, conventional gas recirculation system (EGR) cooler cooling tube is light pipe, helix tube, spiral flat tube, heat-transfer effect mainly by improving a heat-transfer area realizes the lifting of heat-transfer capability, but because these coolers exist complex structure, heat transfer area is little, the shortcomings such as turbulent air flow weak effect, the heat-transfer capability that can reach neither be very desirable.
Summary of the invention
It is simple that the utility model object is to provide a kind of structure, and can increase the heat transfer area of fluid side further, improves turbulent air flow effect, the efficient combined-type cooling tube that heat-transfer capability is promoted energetically.
Technical solution of the present utility model is: efficient combination cooling tube, mainly comprises fin, cooling tube, and described fin is arranged in described cooling tube, described cooling tube is interval with the bulge of evagination.
Preferably, described fin is flow-disturbing side tooth profile fin, and described fin is welded into cooling flat tube assembly by soldering and described cooling tube, and communicate in described cooling tube inside between described bulge formation passage successively.
Preferably, the arrangement form of described bulge is, each bulge is arranged parallel to each other into 1 row or some rows.
Preferably, described bulge is divided into odd number to arrange and even rows, described odd number row is obliquely installed some the first bulges be parallel to each other relative to the minor face of cooling tube, described even rows is obliquely installed some the second bulges be parallel to each other relative to the minor face of cooling tube, and described first bulge is contrary with the incline direction of described second bulge.
Preferably, described fin is after welding combination, and many group fins sawtooth that is square in the cross section of cooling tube airintake direction is wavy.
Preferably, the cross section of described cooling tube is rectangle.
Preferably, the cross section of described cooling tube is strip, and the minor face of strip is arc.
The beneficial effect that the utility model brings is: efficient combination cooling tube by being interval with the bulge of evagination on cooling tube, and bulge is provided with different arrangement modes, add the heat transfer area of fluid side, improve turbulent air flow effect, cooling tube heat-transfer capability is promoted energetically; And this pipe structure for cooling is simple, manufacture process is easy to realize.

In figure: 1 fin, 2 cooling tubes, 3 bulges.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Specific embodiment one
The utility model embodiment as shown in figs. 1-7, mainly comprises fin 1, cooling tube 2, and described fin 1 is arranged in described cooling tube 2, described cooling tube 1 is interval with the bulge 3 of evagination.
Described fin 1 is flow-disturbing side tooth profile fin, described fin 1 is welded into cooling flat tube assembly by soldering and described cooling tube 2, communicate in described cooling tube 2 inside between described bulge 3 formation passage successively, fluid takes away the heat of tail gas in bulge 3 channel flow, adds the heat transfer area of cooling tube 2 fluid side.
The arrangement form of described bulge 3 is, each bulge is arranged parallel to each other into 1 row or some rows.
Described fin 1 is after welding combination, and many group fins sawtooth that is square in the cross section of cooling tube airintake direction is wavy, increases the heat transfer area at fin place.
The cross section of described cooling tube 2 is rectangle or strip, and when the cross section of cooling tube is strip, the minor face of strip is arc.
The present embodiment arranges the bulge 3 of evagination by interval on cooling tube 2, adds the heat transfer area of fluid side, improves turbulent air flow effect, cooling tube 2 heat-transfer capability is promoted energetically; The arrangement mode of bulge 3 is set to each bulge and is arranged parallel to each other into 1 row or some rows, this pipe structure for cooling is arranged simple, manufacture process is easy to realize.
Specific embodiment two
Alternatively embodiment, with specific embodiment one unlike: described bulge 3 is divided into odd number to arrange and even rows, described odd number row is obliquely installed some the first bulges be parallel to each other relative to the minor face of cooling tube 2, described even rows is obliquely installed some the second bulges be parallel to each other relative to the minor face of cooling tube, and described first bulge is contrary with the incline direction of described second bulge.
The present embodiment is obliquely installed some the first bulges be parallel to each other by the arrangement of bulge 3 being set to odd number row relative to the minor face of cooling tube 2, even rows is obliquely installed some the second bulges be parallel to each other relative to the minor face of cooling tube 2, first bulge is contrary with the incline direction of the second bulge, on the basis of embodiment one, the present embodiment adds the area of the passage formed between each bulge 3 to a greater extent, namely the heat transfer area of fluid side is increased, improve turbulent air flow effect, improve the heat-transfer capability of cooling tube to a greater extent, and the bulge of odd number row and even rows is parallel to each other separately in the present embodiment, manufacture process is also easy to realize.
The operation principle of efficient combination cooling tube of the present utility model is: tail gas absorbs the heat of tail gas by fin 1 from one end of cooling tube 2, the heat in tail gas is also taken away in the bulge 3 that meanwhile fluid flows through cooling tube, thus reduce the delivery temperature of vehicle exhaust, discharge from the other end of cooling tube 2.
It should be noted that: above-described embodiment is only can one of the mode realizing technical solutions of the utility model; the scope of the protection required by the utility model is not limited to above-described embodiment, also should include other embodiment that those of ordinary skill in the art can change according to the technical solution of the utility model.
