Cooling circuit of oil cooler for vehicle

Abstract

A cooling circuit of an oil cooler for a vehicle that reduces the number of parts and provides an elegance appearance of the engine by applying a cooling circuit structure of a parallel type oil cooler having a good layout and a high cooling efficiency to configure the cooling circuit of the oil cooler having a simplified and independent flow path structure without any pipe coming out of the engine. The cooling circuit receives a cooling water of the lowest temperature through a cooling water inlet formed in a cylinder block to cool the oil cooler and directly connects the cooling water of the oil cooler to a cooling water intake established in a water pump.

1 . A cooling circuit of an oil cooler for a vehicle, comprising a cooling water inlet formed in a cylinder block to cool the oil cooler and a cooling water intake established in a water pump wherein the cooling circuit receives cooling water at a lowest temperature through said cooling water inlet and directly connects to a cooling water intake for direct communication of the cooling water of the oil cooler thereto. 
   
   
       2 . A cooling circuit of an oil cooler for a vehicle, comprising:
 a water pump mounted in cooperation with an engine cylinder block;   a cooling water intake and a cooling water outlet defined in the water pump through which cooling water at low temperature cooled in a radiator and is received and supplied to the cylinder block;   a cooling water inlet, provided in the cylinder block, through which the cooling water discharged via the cooling water outlet is introduced to the cylinder block;   an oil cooler inlet and an oil cooler outlet, arranged in the cylinder block, through which the cooling water is supplied from the cooling water inlet to the oil cooler to cool the oil cooler and, then, discharged again to the cylinder block; and   a path for collecting cooling water, formed in the water pump, through which the cooling water introduced via the oil cooler outlet to the cylinder block is supplied to the cooling water intake of the water pump.   
   
   
       3 . The cooling circuit of an oil cooler for a vehicle as recited in  claim 1  or  2 ,
 wherein the oil cooler inlet and outlet have a pressure difference therebetween.   
   
   
       4 . The cooling circuit of an oil cooler for a vehicle as recited in  claim 1  or  2 , wherein the cooling circuit is integrated into the cylinder block and the water pump only.
