The reference of related application
The application proposes according to 35U.S.C. § 111 (a), and requires the U.S. Provisional Application No.60/478 of on June 16th, 2003 according to 35U.S.C. § 111 (b) submission, 360 priority according to 35U.S.C. § 119 (e) (1).
Technical field
The present invention relates to heat exchanger and for example be used for automotive air-conditioning condenser or the evaporimeter of automobile air-conditioning refrigeration circulation as automotive air conditioning device.The invention still further relates to the fin (hereinafter referred to as " heat-exchanger fin ") that is used for heat exchanger, for example wait to be installed to venetian blind type fin or corrugated fin in the said apparatus.
Background technology
The evaporimeter of heat exchanger-for example be used for automobile air-conditioning refrigeration circulation or condenser-comprise heat-exchange tube that cold-producing medium therefrom passes through and the heat-exchanger fin that vertically is provided with perpendicular to this heat-exchange tube, thereby via fin air and flow through between the cold-producing medium of heat-exchange tube and carry out heat exchange around.
According to using and/or required performance, use venetian blind type fin, offset fin (offset fin), nail formula fin (pin fin) etc. usually as heat-exchanger fin.
In venetian blind type fin-type heat exchanger as shown in Figure 11, be parallel to a plurality of venetian blind type fins 50 that the incoming direction X of air A is provided with layouts that be parallel to each other at certain intervals on perpendicular to the direction of air incoming direction X, thus between adjacent venetian blind type fin 50 formation air flue 60.Each venetian blind type fin 50 has at vertical (the air channeling direction) of air flue 60 goes up a plurality of cuttings and the crooked louver board 51 that is provided with.The air A that introduces each air flue 60 along louver board 51 by the shutter gap between the proximate louver 51 that is formed on each venetian blind type fin 50, thereby at air A and by heat-shift between the cold-producing medium of heat-exchange tube (not shown).
As a kind of method of improving the hot property of this heat exchanger, the spacing by reducing louver board 51 with the quantity that increases louver board 51 so that increase the windward side edge of louver board 51 and the contact area between the air A can be thought effectively.
But, less louver board spacing may cause taking place sand and dust between proximate louver 51 stops up and/or condensed water bridge joint/shunting, thereby makes the air A by air flue 60 can not be introduced in the louver board gap that forms between the proximate louver 51.Can cause air A by-pass flow like this, promptly air flows through the fin gap that forms and is not introduced into the louver board gap between adjacent venetian blind type fin, causes coefficient of overall heat transmission variation.
On the other hand, in the venetian blind type fin-type heat exchanger, disclosed patent gazette No.H6-221787 of Japanese unexamined (Fig. 1 and 3) and U.S. Patent No. 5730214 (Fig. 5～7) disclose by changing the technology that louvered angle improves heat exchange performance.
In addition, the disclosed patent gazette No.H1-263498 of Japanese unexamined (page or leaf 1～2) discloses a kind of technology that limits the optimal value of spacing of fin, fin thickness, louver board spacing and louver board angle.
Yet, in nearest heat exchanger technical field, especially in air conditioning for automobiles heat exchanger technical field, need further to improve heat exchange performance.Therefore, also need further to improve the coefficient of overall heat transmission of heat-exchanger fin.
An object of the present invention is to provide a kind of coefficient of overall heat transmission improves thereby the extraordinary heat exchanger of heat exchange performance, for example automotive air-conditioning condenser or evaporimeter.

The specific embodiment
Fig. 1 be evaporimeter that heat exchanger according to the embodiment of the invention-for example be used for automotive air conditioning device partly is shown-fin and near the perspective diagram of incision, Fig. 2 is the enlarged cross-sectional view that the venetian blind type fin of the heat exchanger that is applied to the foregoing description is shown, and Fig. 3 is the enlarged cross-sectional view according to the front portion of the fin of the heat exchanger of the foregoing description.In the following description, in order to help to understand the present invention, be the fore-and-aft direction of heat exchanger with respect to the heat exchanger of this embodiment along the direction of air incoming direction X with supposition.
As shown in these figures, in this heat exchanger, a plurality of flat heat exchange tubes 1 and 2 left and right directions along heat exchanger are parallel to each other and are arranged to two rows at certain intervals, and each heat-exchange tube is all gone up in the direction (being above-below direction) perpendicular to air incoming direction X and extended.Be provided with corrugated fin 3 between the adjacent heat-exchange tube of arranging along the width of heat exchanger 1 and 1 (2 and 2).
Each venetian blind type fin 4 has a plurality of louver boards 5, and some zone of crooked venetian blind type fin forms described louver board by cutting also on fore-and-aft direction at certain intervals.Therefore, the air A that enters air flue 6 will be introduced the louver board gap that is formed between the adjacent louver board 5 by louver board 5, thus via fin at air A and flow through between the cold-producing medium of heat-exchange tube 1 and carry out heat exchange.
In this embodiment, if louvered air is defined as the louver board width along its length of passing through, then the above-mentioned a plurality of louver boards 5 in each venetian blind type fin 4 comprise wide louver board 5a and the less narrow louver board 5b of louver board width that the louver board width is bigger, and wide louver board and narrow louver board are alternately arranged.
In this embodiment, if with " Lwl " expression wide louver board 5a the louver board width, then preferably width Lwl is set at 0.8～1.3mm.Be 0.85mm or bigger more preferably, and the upper limit is set at 1.2mm or littler lower limit set.In addition, if with " Lws " expression narrow louver board 5b the louver board width, then preferably width Lws is set at 0.1～0.6mm.Be 0.15mm or bigger more preferably with lower limit set.
Louver board width Lwl and Lws are too small or cross conference because produce the air by-pass flow or make the coefficient of overall heat transmission variation of venetian blind type fin 4 because the pressure loss increases, thereby cause the heat exchange performance variation.
In addition, in this embodiment, preferably the ratio Lws/Lwl with the louver board width " Lws " of narrow louver board 5b and the louver board width Lwl of wide louver board 5a is set at 0.1～0.7.Be 0.3 or bigger more preferably with lower limit set.
From hereinafter with the example of explanation as can be seen, the louver board width is more too small or cross conference because produce the air by-pass flow or make the coefficient of overall heat transmission variation of venetian blind type fin 4 because the pressure loss increases than Lws/Lwl, thereby causes the heat exchange performance variation.
In addition, in this embodiment, each louver board 5 is set at substantially constant with respect to the angle La (louver board angle) as the venetian blind type fin 4 of heat exchanger plate.Preferably louver board angle La is set at 22 °～36 °.More preferably, to be set at respectively be 24 ° or bigger and 32 ° or littler for the lower limit and the upper limit.
