Description of the Related Art Generally, an automobile is provided with a radiator (heat exchanger) for circulating cooling water through an engine to cool the engine and a heater core for heating the interior of the vehicle. In such a vehicle heat exchanger, a box-shaped upper tank and a lower tank are respectively connected by a plurality of tubes, and the inside of the upper tank is further partitioned by a partition wall into a cooling water inlet side and a cooling water outlet side. I have. In addition, a plurality of fins are provided between each tube in order to increase a heat exchange area.

にこの上部タンクからエンジン側へと導出される。In this vehicle heat exchanger, the cooling water flowing into the cooling water inlet of the upper tank flows through the tube to the lower tank. Here, when the cooling water passes through the tube, heat exchange is performed with the air flowing outside the tube through the tube wall. The cooling water after the heat exchange flows into the lower tank from the tube, and flows from the lower tank to the upper tank through another tube. Here, even when the cooling water passes through the tube, heat exchange is performed again with the air flowing outside the tube. Such heat exchange is repeated in each tube, and the cooling water after completing the heat exchange flows into the cooling water outlet side of the upper tank, and is further drawn out from the upper tank to the engine side.

It flows to the lower tank chamber 15 side through 11a. When the cooling water flows in the tube 11a, heat exchange (radiation) is performed between the cooling water and air flowing outside through the wall of the tube 11a and the fins 12a. The cooling water subjected to the heat exchange is supplied to the lower tank chamber 2
1 and again through the tube 11b.
It flows to the 4 side. When the cooling water flows inside the tube 11b, heat exchange (radiation) is performed between the cooling water and the outside air through the wall of the tube 11b and the fins 12b. The cooling water after performing the heat exchange repeatedly in this manner is the tube 12b
From the cooling water outlet side chamber 18 and further sent to the engine through a refrigerant discharge pipe 20.

Since the inner diameter of the tube 1b is formed larger than the inner diameter of the tube 12b, even if some corrosion products accumulate in the tube 11b on the cooling water outlet side, clogging hardly occurs and the heat exchange property does not decrease.

The filter 23 has a large number of fine holes as shown in FIG. 5, and filters corrosion products to prevent corrosion products having a large particle diameter from flowing into the tube 11b on the cooling water outlet side. Thus, high-purity cooling water flows through the tube 11b on the cooling water outlet side.

抗を減少させることができる。In the case of the heat exchangers according to the second and third embodiments, the corrosion progresses in the tube 11 and the corrosion products generated in the tube 11 on the cooling water inlet side are transferred to the lower tank 15. Even if it flows into the cooling water, since it is filtered by the filters 23 and 24, high-purity cooling water flows through the cooling water outlet side chamber 21b to the tube 11b side on the cooling water outlet side. This prevents the corrosion products from being deposited on the tube 11b on the cooling water outlet side, prevents clogging due to the deposition of the corrosion products, and does not cause deterioration in heat exchange properties. When the filters 23 and 24 are compared, the filtering performance of the filter 24 is further improved, and the flow resistance of the cooling water can be reduced.

を可能にする。As described above, according to the vehicle heat exchanger of the present invention, the inner diameter of the tube on the cooling water outlet side is formed larger than the inner diameter of the tube on the cooling water inlet side. Clogging due to accumulation of corrosion products in the tube on the cooling water outlet side is prevented. Further, since a filter is provided in the tank to filter corrosion products flowing into the tank from the tube on the cooling water inlet side, the corrosion products are prevented from flowing into the tube on the cooling water outlet side, and corrosion is prevented. Clogging due to product accumulation is further avoided. Therefore, the present invention can be
