本考案は熱交換器、特に車輌用冷房装置の横置
きタイプの熱交換器に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat exchanger, particularly a horizontal type heat exchanger for a vehicle cooling system.
一般に車輌冷房装置用の熱交換器はケースに収
納されて車輌前席の助手席側ダツシユボードの下

が多い。これに使用される熱交換器は折曲蛇行す

縦置きタイプと、水平方向に配置した横置きタイ
プの何れかが採択される。 In general, heat exchangers for vehicle cooling systems are often housed in a case and installed under the dash board on the passenger side of the front seat of the vehicle, so that there is plenty of space for the feet of the occupants. The installation space for the heat exchanger is often horizontally elongated. The heat exchanger used for this purpose is either a vertical type in which parallel portions of bent and meandering flat tubes are arranged vertically, or a horizontal type in which parallel parts are arranged in a horizontal direction.

水が偏平管の空気流の下流側辺から飛水し、排水
処理が困難である等の欠点がある。 By the way, in a heat exchanger, the intake air for cooling is cooled by exchanging heat with the refrigerant flowing inside the flat tubes, and at the same time, moisture in the air becomes condensed water and is blown onto the surface of the corrugated fins and flat tubes by the air flow. The condensed water then reaches the downstream side, but treatment of this condensed water becomes a problem in the heat exchanger. In other words, using a vertical type in a horizontally long installation space is good for draining condensed water, but as the number of stages of flat tubes increases, the number of bent portions of the flat tubes also increases, making it relatively difficult for corrugated fins to be pinched. There are drawbacks such as a reduction in the surface area of the heat exchanger, and a decrease in the ratio of the front-to-face area of the heat exchanger to a predetermined front-to-face area of the installation space, resulting in poor cooling efficiency. On the other hand, with the horizontal type, the ratio of the front-to-front area of the heat exchanger to the front-to-front area is larger, but condensed water splashes from the downstream side of the airflow of the flat tube, making it difficult to treat wastewater. There are drawbacks.

換器を提供するものである。 The present invention is an improvement on the horizontal type heat exchanger in view of the above-mentioned points.The flat tube that defines the refrigerant flow path is bent and meandered, and corrugated fins are sandwiched between the parallel parts. A heat exchanger configured by connecting refrigerant inflow and outflow headers to both ends of the flat tube, and in which the parallel portions are arranged horizontally,
The flat tube has a protrusion of a predetermined length integrally formed along the downstream side of the air flow, and a filament of a predetermined depth is formed at a predetermined position on the front and back surfaces of the protrusion so that the protrusion protrudes from the filament. The strip is bent upward to form a horizontal water guide groove, and at the end of the water guide groove, the protruding strip is notched to an appropriate width to form a drainage section, so that condensed water flows over the surfaces of the corrugated fin and flat tube. To provide a heat exchanger that is blown away, flows into a water guide groove, is drained from a drainage part, and can prevent condensed water from flying out from the downstream side of the airflow of a flat tube.

く。 As shown in Figure 1, the heat exchanger consists of a band-shaped flat tube 1
The inflow header 2 and the outflow header 3 are connected to both ends of the flat tube 1, and the corrugated fins 4 are sandwiched between the adjacent parallel parts 1a of the flat tube 1. An end plate 5 is fixed to the flat tube 1, and a frame 6 is attached to the bent portion 1b of the flat tube 1. The intake air for cooling is taken in from the back side of the drawing, is cooled by the heat of evaporation of the refrigerant flowing inside the flat tube 1 when passing through the corrugated fins 4, and is discharged towards the front side of the drawing. As shown in FIG. 2, the flat tube 1 is a cross-sectional porous tube structure in which a plurality of refrigerant channels 7 are formed inside, and is formed by extrusion molding or the like using a material with good thermal conductivity such as aluminum. A protrusion 8 integrally formed with the flat tube 1 is formed along one side, and filaments 9 and 10 of a predetermined depth are provided at corresponding predetermined positions on the front and back surfaces of the protrusion 8. It is engraved along the The reason why the filaments 9 and 10 are provided on the front and back surfaces of the protrusion 8 is to make it easy to bend the protrusion 8 in either direction by using the filaments 9 and 10 as bending parts. As shown in FIG. 3, the flat tube 1 is disposed within the heat exchanger so that the side surface provided with the protrusion 8 is located on the downstream side of the air flow. Flat tube 1
In each of the parallel parts 1a sandwiching the corrugated fins 4, the tips 8a of the protrusions 8 are connected to the filaments 9, 1.

されることになる。 In the above configuration, the condensed water is transferred to the corrugated fin 4.
The water is blown away by the air flow on the surface of the flat tube 1 and flows into the water guide groove 11. Since the water guide groove 11 is in the shadow of the air flow, the condensed water flowing into the water guide groove 11 is guided to the drainage part 12 at the end of the water guide groove 11 without being scattered, and is quickly drained. If the heat exchanger is arranged at an angle of θ with respect to the horizontal in a lateral direction when viewed from the front, the condensed water can be drained more quickly.

Particularly when the heat exchanger is arranged at an angle, it is sufficient to provide the drainage section 12 only at the downstream end of the water guide groove 11.

利点がある。 As explained above, according to the present invention, a protrusion integrally formed with the flat tube is bent upward on the downstream side of the air flow of the flat tube, and the protrusion is bent upward along the side of the parallel portion of the flat tube. Since a water guide groove is formed in the direction of the water guide groove and drainage portions are formed at both ends of the water guide groove, the condensed water is blown away by the air flow on the surface of the corrugated fin and the flat tube and flows into the water guide groove. Water is drained from the drainage portion at the end, and water can be prevented from splashing from the sides of the flat tube. Therefore, by using a horizontal type that matches the shape of the space instead of a vertical type in a horizontally long installation space, the ratio of the heat exchange section to the predetermined front-to-front area of the installation space increases, improving cooling efficiency. be able to. In addition, striations are formed on both sides of the protrusion, and the striations are used as bent portions to form water guide grooves by bending the tips of the striations of the protrusion. In each of the parallel parts of the flat tube where repeating is repeated, no matter which surface of the protrusions is the upper surface, the water guide groove can be formed by bending all the tips of the protrusions in the parallel parts upward, This has the advantage of improving the ease of assembling the heat exchanger.
