Abstract

The utility model relates to a base device for fixing fins of a radiator, which is composed of radiator fins and a fixing base. The utility model is characterized in that one side of the fixing base is provided with a plurality of grooves; the depth of the groove is divided into a deep groove and a shallow groove; the width of the opening of the grooves is wider than the width of the bottom part, so as to make the inner wall of the groove is in the shape of slant; the deep and shallow grooves are arranged on the fixing base with the structural arrangement of mutual interval; the deep groove accepts the radiator fins which are inserted into the deep groove; the shallow groove is auxiliary squeezing groove. The fins are pressed into the base of the preformed groove by the way of machinery. Because of the deformation of the both-side materials of the groove, the fins is clamped and fixed to make a fin type radiator whose radiating efficiency is higher.

Description

Base device for fixing fin of radiator

The utility model relates to the part apparatus of heat-exchange apparatus in a kind of mechanical engineering field, particularly relates to a kind of radiator vanes fixed base device of new structure.

Existing radiator blade generally is by the aluminium extrusion moulding, and the restriction of the radiator that forms when being squeezed the mould making, and influencing radiator shutter can not be oversize or too thin, its radiating efficiency thereby be restricted.

Main purpose of the present utility model is to overcome the defective of prior art, and a kind of radiator vanes fixed base device is provided, and makes it utilize mechanical system that blade is pressed into and gives in the base that leaves groove earlier, to make the higher gilled radiator of radiating efficiency.

The purpose of this utility model is realized by following technical scheme.

A kind of radiator vanes fixed base device, form by radiator shutter and firm banking thereof, it is characterized in that: a side of this firm banking is provided with a plurality of grooves, gash depth is divided into two kinds of deep trench, shallow trench, the groove opening place is wide than the bottom, makes the inwall of groove be skewed, and structure configuration dark, shallow trench adopts the space on firm banking, deep trench is inserted in this deep trench for accepting radiator shutter, and shallow trench is auxiliary extruded channels.

The utility model compared with prior art has tangible advantage and effect thereof, it can utilize mechanical system blade to be pressed in the base that leaves groove in advance, to make the higher gilled radiator of radiating efficiency, it can make the radiator blade dimensions unrestricted, and radiating efficiency can improve greatly.

Concrete structure of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Fig. 1 is the sectional view of the utility model punching press stage structures.

Fig. 2 is the sectional view that the utility model is fixedly finished stage structures.

Fig. 3 is the partial enlarged drawing of the utility model punching press stage structures.

Fig. 4 is the partial enlarged drawing that the utility model is fixedly finished stage structures.

Fig. 5 is the strabismus stereogram that the utility model is fixedly finished stage structures.

Below in conjunction with accompanying drawing and preferred embodiment, to concrete structure of the present utility model, feature and effect, describe in detail as after.

See also Fig. 1 to shown in Figure 5, the utility model radiator vanes fixed base device, it is made up of radiator shutter 1 and firm banking 4 thereof, be provided with a plurality of groove 2 and secondary trenches 3 accepted in a side of firm banking 4, it is darker wherein to accept groove 2 degree of depth, secondary trenches 3 degree of depth are more shallow, the groove opening place is wide than the bottom, make trench wall be skewed, and accepting groove 2 and secondary trenches 3 is to adopt the structure configuration that is the space on firm banking, the darker groove 2 of accepting is inserted in this and accepts in the groove 2 for accepting radiator shutter 1, secondary trenches 3 is auxiliary extruded channels, form distortion part 5 after its both sides extrusion, (as shown in Figure 4) utilize mechanical system blade 1 to be pressed in the firm banking 4 that leaves groove in advance, because of the distortion of groove both sides material, and will place the blade of accepting in the groove 21 to clamp and fix, to make the higher gilled radiator of radiating efficiency.
