Claims

[Scope of utility model registration request]

A required number of annular dish-shaped plates having flanges on the periphery and outer periphery of the central opening are sandwiched between the upper and lower end plates having the central opening and stacked, and the layered space formed between each plate is further spaced. The lower end plate is provided with an oil inlet hole that communicates with the oil chamber so that the lower surface of the lower end plate communicates with the oil chamber, and the upper end plate is provided with an oil outlet hole that communicates with the oil chamber, and a water inlet hole and water outlet hole that communicate with the water chamber, and a hollow center bolt that passes through the center opening of the upper and lower end plates and each plate is inserted, and the center bolt The oil outlet hole is communicated with the hollow center bolt inner passage through a through hole provided on the side surface of the plate, and an annular passage is formed between the central opening of the plate and the upper end plate and the side surface of the center bolt to communicate with the through hole. A housingless oil cooler comprising: a lower end plate further provided with a throttle passage, and the annular passage communicates with a lower surface of the lower end plate through the throttle passage.
