Claims

[Claims for Utility Model Registration] (1) A housing-less type oil having an oil filter connected adjacently to the oil filter by a connector pipe, having a supply passage for supplying oil to the oil filter, and cooling the oil returning from the oil filter. The cooler includes a core for exchanging heat between oil and water, a cover fixed to the lower part of the core and having an oil inflow chamber and a discharge chamber, and a water supply chamber and a water discharge chamber, and an upper part of the core. an upper plate secured within the core and having an inlet for supplying oil to an oil filter and a return passage for receiving purified oil from the oil filter; and an oil supply secured within the core and communicating the inlet chamber with the inlet. an oil supply port forming a passage, a return port forming an inflow passage connecting the return passage to an oil heat exchange chamber in the core, and a drain oil forming an outflow passage connecting the oil heat exchange chamber to the oil drain port. a plurality of core plates having a port, a water supply port forming a water flow passage connecting the water supply chamber to a hydrothermal exchange chamber in the core, and a drainage port connecting the hydrothermal exchange chamber in the core to the drainage chamber; The oil supply port, the return port, the oil drain port,
An annular bent portion is formed around the water supply port and the drainage port, and the oil supply port, return port, oil drainage port, water supply port, and drainage port are formed by shifting the adjacent core plates by an angle of 90°. A housing-less type oil cooler featuring the following features. (2) The four oil supply ports are formed on the same circumference at angular intervals of 90°, and the return port, oil drain port, water supply port, and drainage port are formed on the same circumference at angular intervals of 90°. A housing-less type oil cooler according to claim (1) of the registered utility model, which is formed as a single unit.
