Abstract

PURPOSE:To manufacture at a low cost a heat exchanger excellent in durability by a method wherein liquid pipes of synthetic resin containing fine metallic pieces are inserted into through holes on a synthetic resin base plate and induction heating is conducted to be welded to the base plate. CONSTITUTION:Liquid pipes 1a of synthetic resin of the same kind as that of a base plate 4 and containing fine metallic pieces (preferably, iron powder, ferrous alloy powder) are inserted into the holes 6 of the synthetic resin base plate 4 on the peripheral edge of which vertical walls 8 are equipped in the form of a short cylinder. Then, under the situation that the outside of each liquid pipe 1a and the inside of the respective vertical wall 8 are stuck to each other, electric current is applied to a high frequency induction coil 9 arranged around each vertical wall 8, high frequency induction current is generated in the fine metallic pieces contained in each liquid pipe 1a to obtain Joule heat. Each vertical wall 8 on the base plate 4 and the inserting portion of the respective liquid pipe 1a are welded into one body. This body is set tightly to a tank 5 through the base plate 4 to obtain a heat exchanger.

の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a method for manufacturing a heat exchanger having a core portion and a tank portion, which is used as an automobile radiator, a heater core, or the like.

（背　　景　　技　　術） 」二連のような熱交換器は、例えば、第１図に示すよう

．４を介してタンク５．５を固定して成るものである。(Background Art) A double heat exchanger is configured as shown in FIG. 1, for example. That is, a seat plate 4 is provided at both ends of the core portion 3 consisting of a large number of liquid passage pipes 1.1 and fins 2.2.
．． The tank 5.5 is fixed via the tank 4.

て放熱し温度が低下する。When such heat exchange is used, for example, as a radiator to dissipate heat from cooling water, the cooling water can be sent through the inlet pipe provided in the upper tank 5 and discharged from the outlet pipe provided in the lower tank 5. While the water flows down through each liquid passage pipe 1.1, it exchanges heat with the air flowing through the core portion 3, radiates heat, and its temperature decreases.

入している。By the way, in the heat exchanger as described above, one in which the seat plate 4 is made of synthetic resin and the liquid passage pipe 1 is made of metal is known. FIG. 2 shows a partially enlarged sectional view of such a heat exchanger. A seat plate 4 also made of synthetic resin is liquid-tightly fixed to the opening of the tank 5 made of synthetic resin by means such as ultrasonic welding. 7, and then this backing 7
The end of a liquid passage tube 1 made of metal such as aluminum is inserted inside the tube.

を傷め易く、不良品の発生率が高くなってし・まう。However, the conventional heat exchanger constructed as described above has the following disadvantages. That is,
The backing 7 is required to liquid-tightly join the metal liquid passage pipe and the synthetic resin seat plate, and the work of fitting the backing 7 to the inner peripheral edge of the through hole 6 is troublesome. This increases the manufacturing cost of the heat exchanger. Furthermore, if the inner peripheral surface of the backing 7 is damaged when the end of the liquid passage tube 1 is press-fitted into the inside of the backing 7, it becomes impossible to maintain liquid tightness between the two members 7 and 1. Furthermore, when the pressure inside the tank 5 becomes -y when the heat exchanger is used, a force is applied to the joint between the seat plate 4 and the liquid passage pipe l in the direction of pulling out the liquid passage pipe l. ,l
In order to prevent the fluid from coming out, the diameter of the end of the liquid passage tube l is slightly enlarged after inserting the banking 7 to prevent it from coming out.
When expanding the diameter of the end of the liquid passage tube 1 in this way, the backing 7
It is easy to damage the product, leading to a high incidence of defective products.

After inserting it inside the vertical wall, by energizing the high-frequency induction coil placed around the vertical wall, a high-frequency induced current is induced in the metal particles contained at the end of the liquid passage tube, causing them to generate heat. After welding the circumferential surface and the outer circumferential surface of the liquid passage pipe, the high-frequency induction coil is removed and the tank is assembled on the seat plate.

The inner circumferential surface of the vertical wall 8 is slightly tapered (for clarity, the inclination is drawn to be larger than it actually is in the drawing) so that the inner diameter gradually becomes thinner as the distance from the core portion increases. On the other hand, the end of the liquid passage pipe 1a inserted into the inside of the vertical wall 8 is slightly tapered so that the outer circumferential surface comes into close contact with the internal circumferential surface of the vertical wall 8.

手段により接合面の加圧を行なう。The seat plate 4 constructed as described above and the end of the liquid passage tube 1a are joined in a liquid-tight manner as follows. That is, as shown in FIG. 4, the end of the liquid passage pipe 1a is inserted into the inside of the standing wall 8, and the outer peripheral surface of the end of the liquid passage pipe 1a and the inner peripheral surface of the standing wall 8 are brought into close contact with each other. A high frequency induction coil 9 positioned so as to surround the periphery of the coil 8 is energized. As a result, a high frequency induced current is generated in the metal particles contained at the end of the liquid passage pipe 1a, and the metal particles generate Joule heat. For this reason, the resin constituting the end of the liquid passage pipe 1'a and the resin on the inner peripheral surface of the vertical wall 8 that the outer peripheral surface of this end is in close contact with are melted, and the melted resins mix with each other to form the liquid passage pipe. The outer circumferential surface of the end portion 1a and the vertical wall 8 are welded together. In order to ensure complete welding on both sides, while the resin on the joint surface is melting,
The joint surface is pressurized by appropriate means, such as pushing an inverted truncated cone-shaped pressing piece into the end of a.
