本発明は自動車等に搭載される熱交換器のヘッダ−構造に関するものであ る。 The present invention relates to a header structure for a heat exchanger installed in automobiles, etc. Ru.
【０００２】0002
従来、自動車の室内空調機器を構成する熱交換器として図２に示すものが知ら れている。この熱交換器１は上下に延び対向して配置された円筒状のヘッダ−２ と、この各ヘッダ−２の接続穴３を介して両端が連通状態で接続し上下に複数段 に架設された偏平状の熱交換チュ−ブ４とを有し、この熱交換チュ−ブ４の上下 面に熱交換フィン５が介装されている。この熱交換フィン５のうちで、最上位及 び最下位の熱交換フィン５の上下面には補強プレ−ト６が取付けられている。 Conventionally, the heat exchanger shown in Figure 2 is known as a heat exchanger that constitutes the indoor air conditioning equipment of automobiles. It is. This heat exchanger 1 has a cylindrical header 2 which extends vertically and is disposed facing each other. Both ends of each header 2 are connected in a communicating state through the connection hole 3 of each header 2, and multiple stages are formed vertically. It has a flat heat exchange tube 4 installed on the top and bottom of the heat exchange tube 4. Heat exchange fins 5 are interposed on the surface. Among these heat exchange fins 5, Reinforcement plates 6 are attached to the upper and lower surfaces of the heat exchange fins 5 and the lowest heat exchange fins.
【０００３】 また、この熱交換フィン５とヘッダ−２の側面との間には間隙Ａが形成され、 ろう付け時に発生するエロ−ジョンを防止している。即ち、この熱交換フィン５ とヘッダ−２とが接しているときは、熱交換フィン５とヘッダ−２との接触部分 にろう材が集中して、この部分の融点が低下して穴が形成されるおそれがあるか らである。0003 Further, a gap A is formed between the heat exchange fins 5 and the side surface of the header 2, Prevents erosion that occurs during brazing. That is, this heat exchange fin 5 When the heat exchange fins 5 and the header 2 are in contact with each other, the contact portion between the heat exchange fins 5 and the header 2 Is there a risk that the filler metal will be concentrated and the melting point of this area will drop and holes will form? It is et al.
【０００４】0004
しかしながら、前記従来の熱交換器では、熱交換空気の一部がこの間隙Ａを通 り抜け、熱効率を低下させるという問題点を有していた。また、ヘッダ−２が円 筒状となっているため、このヘッダ−２を介してブラケット７にて図示しない車 体にこの熱交換器を取付けるとき、このブラケット７をヘッダ−２の外周面に対 応するよう形成しなければならず、面倒なものとなっていた。さらに、前述の如 く熱交換フィン５とヘッダ−２との間に間隙Ａを形成しているが、熱交換チュ− ブ４のヘッダ−２への挿入量が大きいときはこの間隙Ａ部分に熱交換フィン５が 移動し、この熱交換フィン５とヘッダ−２とが接触するという問題点を有してい た。 However, in the conventional heat exchanger, a portion of the heat exchange air passes through this gap A. This has caused problems such as leakage and lowering thermal efficiency. Also, header 2 is yen. Since it has a cylindrical shape, it can be connected to a vehicle (not shown) using the bracket 7 via this header 2. When installing this heat exchanger on the body, place this bracket 7 against the outer peripheral surface of the header 2. It had to be shaped accordingly, which was cumbersome. Furthermore, as mentioned above, Although a gap A is formed between the heat exchange fins 5 and the header 2, the heat exchange tube When the amount of insertion of the fin 4 into the header 2 is large, the heat exchange fin 5 is placed in this gap A. The problem is that the heat exchange fins 5 and the header 2 come into contact with each other. Ta.
【０００５】 本考案の目的は前記従来の課題に鑑み、ヘッダ−と熱交換フィンとの間隙を閉 塞して熱効率を向上させるとともに、ヘッダ−と熱交換フィンとの接触を確実に 防止し、さらには、車体等への取付け作業が簡単な熱交換器を提供することにあ る。[0005] The purpose of this invention is to close the gap between the header and the heat exchange fins in view of the above-mentioned conventional problems. to improve thermal efficiency and ensure contact between the header and heat exchange fins. Our objective is to provide a heat exchanger that prevents heat loss and is also easy to install on vehicle bodies, etc. Ru.

本考案によれば、所定間隙がヘッダ−のタンク部の両側壁により閉塞されてい るため、熱交換空気がこの間隙を通ることがなく、熱効率が向上する。また、タ ンク部が断面方形状に形成されているため、タンク部の各側壁が平面状となり、 この側壁と車体とを連結するブラケットの構造が簡単なものとなる。さらに、タ ンク部の両側壁に設けられた突起により熱交換フィンの移動が規制され、熱交換 フィンと接続プレ−トとの接触を確実に防止できる。 According to the present invention, the predetermined gap is closed by both side walls of the tank portion of the header. Therefore, heat exchange air does not pass through this gap, improving thermal efficiency. Also, Since the tank part is formed with a rectangular cross section, each side wall of the tank part is flat, The structure of the bracket that connects this side wall and the vehicle body becomes simple. In addition, The movement of the heat exchange fins is restricted by the protrusions provided on both sides of the tank, and the heat exchange Contact between the fins and the connection plate can be reliably prevented.
