Intercooler sub-tank for v-type diesel engine cooling water circuit and lubricating oil circuit

Abstract

The invention discloses an intercooler water diversion tank of a cooling water circuit and a lubricating oil circuit of a V-shaped diesel engine. The intercooler water diversion tank comprises a first tank body, a second tank body and a lubricating oil passage; the first tank body is a square cavity; water outlet connecting openings and water return connecting openings are formed in the left and right sides of the first tank body respectively; the water outlet connecting opening and the water return connecting opening in each side communicate with a corresponding circulation water circuit of an intercooler; the second tank body is a circular cavity which is formed by extending from the front end of the lower side of the square cavity, and is provided with a water inlet, a water outlet and an oil inlet; the water inlet communicates with the water outlet connecting openings formed in the left and right sides of the square cavity separately after being diverted by an inner cavity in the second tank body; the water return connecting openings formed in the left and right sides of the square cavity communicate with the water outlet separately after converging through an inner cavity in the first tank body; and the lubricating oil passage slantingly extends upward from the interior of the circular cavity and extends outside from the back side of the square cavity. According to the intercooler water diversion tank, the lubricating oil circuit and the water circuit are in integrated design, so that the whole machine is compact, the arrangement space is saved, and a pipeline is simple.

Description

technical field [0001] The invention relates to the field of V-type diesel engines, in particular to an intercooler water distribution tank for a cooling water circuit and a lubricating oil circuit of the V-type diesel engine. Background technique [0002] At present, the water inlet and outlet structures of the intercooler in the existing V-type diesel engine are all connected to the intercooler and the oil cooler in the form of welded steel pipes or cast pipes. The pipeline layout of the water inlet and outlet structure of the intercooler is relatively complicated. Especially when the V-type diesel engine is designed with two left and right intercoolers, the cooling water needs to be divided into the left and right sides, and needs to converge and return from the left and right sides. If the water inlet and outlet structure of the intercooler is adopted, the pipeline layout will be more complicated. , and takes up a lot of space, affecting the layout of other parts. [00...
