ABSTRACT:
A solderless type automotive engine radiator has upper and lower tanks and a heat exchanger core connected at the upper and lower ends to the tanks through upper and lower header plates. The core is formed by tubes and fins secured to the tubes without soldering. The upper and lower ends of the tubes are in gripping engagement with inner peripheral surfaces of holes formed in the header plates. Layers of adhesive are formed on the surfaces of the header plates adjacent to the core to form liquid-tight seals between the header plates and the tubes. The adhesive layers and the fins are arranged such that at least the fin nearest to an adjacent adhesive layer is either in face-to-face engagement with the adjacent adhesive layer or embedded in the adjacent adhesive layer to strengthen the adhesive layer and protect the same against foreign materials such as water and dirt whereby the durability of the seals is improved.
