Abstract

The invention discloses a laminated inner and outer fin vehicle radiator, which is innovation and improvement on the basis of a 'laminated vehicle radiator' that applies for patent of invention. The width of the cross section of the inner channel of a stack of laminations is increased properly, but the maximum width is not more than 4mm normally, and inner fins are arranged inside; the plane of the inner fins is not provided with windows but with bosses with direction opposite and position staggered. The surface of laminated spare parts applied to containing or connecting the inner fins is not provided with internal ribbed bosses and keeps a plane structure and is in brazed joint with the inner fins, the outer fins and side plates. Therefore, heat-transfer area in the inner channel of the stack of laminations is increased greatly, thereby ensuring that the heat dissipation performance of the laminated vehicle radiator is further improved.

Description

Lamination type inside and outside fin radiator for vehicle

Technical field

The present invention relates to a critical component---the radiator in the car engine cooling system.

Background technology

The present invention has reported patent of invention " lamination type radiator for vehicle " (application number: 200810014764.0) innovation on the basis and raising the author.

" lamination type radiator for vehicle " is to make the internal-rib boss on laminated spare parts in order to improve the method for laminated spare parts internal channel the inside circulation medium turbulence level, in order to strengthen the method for lamination internal channel structural strength, is to make to connect boss on laminated spare parts.Though the internal-rib boss can suitably enlarge the face area of lamination internal channel the inside, but all boss on same lamination side, be that same area with the opposite side surface falls in be that condition is made, and this side that falls in is and outer fin brazed bonded assembly one side, do not have heat conduction between recess and the heat-radiation belt, heat transfer efficiency is subjected to certain influence thus.

Summary of the invention

The objective of the invention is to, suitably the width with lamination internal channel cross-sectional plane strengthens, and inner fin is set, increase considerably the heating area of lamination internal channel the inside thus, inner fin can also further improve the turbulence level of fluid, thereby the heat dispersion that makes lamination type radiator for vehicle obtains new raising, and the Joint strenght that the soldering between the inwall of inner fin and lamination internal channel is connected also the lamination internal channel provides support.

A kind of laminated type inside and outside fin radiator that is used for automobile comprises that lamination, inner fin, outer fin, side plate, the soldering of connecting panel order connect, coolant inlet pipe assembly and outlet pipe component add respectively behind the packing seal with connecting panel by bolted connection.

A preferred embodiment of lamination type inside and outside fin radiator for vehicle is characterised in that, inner fin adopts author's the flat shape heat exchange band (patent No.: 200620084958.4), be placed on the internal channel the inside of stacked wafer moudle, be connected with the inside face soldering of lamination, the passage of inner fin is along vertical placement of lamination, and is communicated with the water space at lamination two ends.

Another preferred embodiment of lamination type inside and outside fin radiator for vehicle is characterised in that, is used to contain, connect the laminated spare parts of inner fin, and its surface does not make the internal-rib boss and is connected boss, keeps planar structure.

Another preferred embodiment of lamination type inside and outside fin radiator for vehicle is characterised in that, (patent No.: structure 200620085887.X), the width of outer fin terminate in lamination width two outsides and disengage part outer fin employing author's recessed band needle recuperator fuse.

Another preferred embodiment of lamination type inside and outside fin radiator for vehicle is characterised in that two laminations paste solder together relatively and constitute a stacked wafer moudle, and the cross-sectional plane outside width of stacked wafer moudle allows to enlarge, but maximum width generally is no more than 4mm.

Another preferred embodiment of lamination type inside and outside fin radiator for vehicle is characterised in that, the material thickness of inner fin generally is greater than or equal to the outer fin on the same core body, but do not allow at the plane of inner fin uplifting window, just produce the boss that direction is opposite, the position is staggered.

Another preferred embodiment of lamination type inside and outside fin radiator for vehicle is characterised in that, outer fin also adopts flat shape heat exchange band, but its specification, model are general and inner fin is inequality, and outer fin requires and must window on the plane, do not make boss, the channel direction of outer fin and inner fin intermesh 90 °, and material thickness can be equal to or less than inner fin, outer fin is placed between the stacked wafer moudle, is connected with the outside face soldering of stacked wafer moudle.

The specific embodiment

Fig. 1 is the front view according to lamination type inside and outside fin radiator for vehicle of the present invention.Lamination (3), inner fin (4), outer fin (2), side plate (1), the soldering of connecting panel (6) order connect, again with coolant inlet pipe assembly (9), outlet pipe component (10), packing seal (7), fastening by bolt assembly (5), fit on radiator cap (8) and blow off valve (11).

Fig. 3 takes out the part of core body from the rectangle frame E of Fig. 1, cut amplification again open, introduce the structure of lamination type inside and outside fin radiator for vehicle in detail, inner fin adopts the flat shape heat-radiation belt, be placed on the internal channel the inside of stacked wafer moudle, be connected with the inside face soldering of lamination, the passage of inner fin is along vertical placement of lamination, and be communicated with the water space at lamination two ends, inner fin interlocks 90 ° with the channel direction of outer fin, outer fin also adopts the flat shape heat-radiation belt, is placed between the stack of laminations, is connected with the outside face soldering of stack of laminations.

Among Fig. 4, cancel the internal-rib boss above the lamination and be connected boss, changed planar structure into.

Shown in Figure 6, outer fin adopts the structure of recessed band core, and the width of outer fin terminates in it and lamination width two outsides disengage part.

Among Fig. 7, the width dimensions of outstanding stack of laminations cross-sectional plane represents that with letter b maximum width generally is no more than 4mm.

Fig. 8 introduces the cross-sectional structure of inner fin in detail, does not window in the plane of inner fin, and still, be manufactured with the position above it and interlock, the boss that direction is opposite, its effect is in order not reduce the structural strength of self, also will to improve the turbulence level of fluid.
