Claims (1)

[Scope of utility model registration request] An upper end plate is attached to the upper and lower end surfaces of the cooler core, which divides a layered cavity formed by laminating dish-shaped plates into an oil chamber and a water chamber every other layer, and has an oil passage, a water supply passage, and a drainage passage inside. and the lower end plate are fixed, and the lower surface of the lower end plate is integrally molded to form a water supply chamber with a water supply pipe attached, a drainage chamber with a drain pipe attached, and an oil supply chamber with an oil inlet. Fix the cover,
The water supply chamber, drainage chamber, and oil supply chamber are communicated with the water supply passage, drainage passage, and oil passage in the cooler core through openings in the lower end plate, and the water flow flowing out from the water supply pipe outlet into the water supply chamber is directed toward the water supply passage. A housing-less type oil cooler equipped with a deflection plate that deflects the air.
