Abstract
The utility model relates to a novel structure of a gilled tube radiator, in particular to a radiator with a solderless core comprising radiation fins and a main leaves and radiating pipes which are inserted between the radiation fins and the main leaves, which are parallelly arranged, wherein, each main leaf is provided with a header tank or a lower tank; the radiation fins and the main leaves are provided with pipe orifices which are inserted with the radiation pipes. The utility model is characterized in that the radiation pipes are sleeved with gum covers which are positioned in the pipe orifices on the main leaves. The radiator has the characteristics that the service life is long, the shaking can be released when an internal-combustion engine works, and the work noise can be reduced.
Description
Technical field
The utility model relates to a kind of new construction of gilled tube radiator, is the unjointed radiator of a kind of core body specifically.
Background technology
At present, in the water-cooled engine cooling system, generally adopt gilled tube radiator.This radiator adopts copper pipe type core body or copper corrugated tube type core body or aluminium pipe rock formula core body.Which kind of gilled tube radiator all is to adopt the plumber's skill that rises that fin or heat-radiation belt are fixed on the radiating tube, and then with the method for welding will about main leaf be welded on the two ends of radiating tube.The position of welding has changed local metallic character, and corrosion easily causes lower header to leak, and in addition, because welding is to be rigidly connected, produces bigger noise when being given a shock, and vibrations also cause weld cracking easily.
Summary of the invention
The purpose of this utility model provides the unjointed radiator of a kind of core body, under the prerequisite that guarantees heat dispersion, improves the service life of radiator, reduces vibrations, reduces operating noise.
For achieving the above object, the utility model adopts following technical scheme:
The unjointed radiator of a kind of core body described in the utility model, comprise fin, the main leaf that be arranged in parallel and intert radiating tube in fin and main leaf, upper tank or lower header are installed on the main leaf, have pore on fin and the main leaf, radiating tube is inserted in this pore, it is characterized in that: be set with gum cover on radiating tube, this gum cover is arranged in the pore on the main leaf.
Above-mentioned gum cover has the body of tubulose, the outer wall of body one end inwardly is shrunk to chamfering, the outer wall of the other end forms step-like sealing cap to external upset (EU), and when gum cover was installed in the pore on the main leaf, sealing cap was positioned at the upper tank of main leaf or a side of lower header inside.
After adopting technique scheme, this radiator has long service life, the vibrations in the time of alleviating internal combustion engine, reduces the characteristics of operating noise.

The specific embodiment
As Fig. 1---shown in Figure 4, the unjointed radiator of a kind of core body described in the utility model comprises fin 1, the main leaf 4 that be arranged in parallel and interts radiating tube 2 in fin 1 and main leaf 4, upper tank 3 or lower header 5 are installed on the main leaf 4, have pore on fin 1 and the main leaf 4, radiating tube 2 is inserted in this pore.Be set with gum cover 6 on radiating tube 2, this gum cover 6 is arranged in the pore on the main leaf 4.
As shown in Figure 5, gum cover 6 has the body 61 of tubulose, the outer wall of body 61 1 ends inwardly is shrunk to chamfering, be convenient to install in pore, the outer wall of the other end of body 61 forms step-like sealing cap 62 to external upset (EU), when gum cover 6 is installed in the pore on the main leaf 4, sealing cap 62 is positioned at the upper tank 3 of main leaf 4 or a side of lower header 5 inside, after installing like this, sealing cap 62 can play the effect of sealing, prevents that upper tank or lower header from leaking.
During installation, fin 1 and radiating tube 2 still adopt traditional plumber's skill that rises to be fixed, after installing main leaf 4 on the radiating tube 2, at first between radiating tube 2 and main leaf 4, install gum cover 6, it is enclosed within on the radiating tube 2 in the slit between radiating tube 2 and main leaf 4, and then with the method for the pipe that rises with its tensioner, fixing.
Owing to adopt gum cover to connect between radiating tube 2 and the main leaf 4, be a kind of elastic connection way, the mechanical shock in the time of can effectively alleviating internal combustion engine reduces noise; In addition, because the rubber decay resistance is strong, can increase the service life greatly.
