Heat exchanger for cooling oil with water
First Claim
1. A heat exchanger for cooling oil with water, comprising:
- a plurality of plates stacked together to form a core portion of said heat exchanger such that a plurality of oil chambers for receiving the oil and a plurality of water chambers for receiving the water are alternately formed between said plates, said water chambers being communicated with each other through first and second water passages;
a first wall portion for defining a through hole in said core portion, said through hole allowing the oil to flow therethrough and having first and second ends at first and second sides of said core portion respectively, said first end being one of an inlet for allowing the oil to flow into said core portion and an outlet for allowing the oil to flow out of said core portion;
a second wall portion for defining a first oil passage in said core portion, said first oil passage extending between said first and second sides of said core portion to communicate with said oil chambers, said first oil passage having first and second ends at said first and second sides of said core portion respectively, said first end of said first oil passage being the other of said inlet and said outlet;
a third wall portion for defining a second oil passage in said core portion, said second oil passage extending between said first and second sides of said core portion to communicate with said oil chambers;
said second oil passage having first and second ends at said first and second sides of said core portion respectively, a first blocking plate for blocking a part of said first and second oil passages such that a flow of the oil is turned from one of said first and second oil passages to the other of said first and second oil passages; and
a first cover member for sealingly covering said second side of said core portion, said first cover member having an oil passage extending between said second end of said through hole and at least one of said second end of said first oil passage and said second end of said second oil passage.

Abstract
A heat exchanger for cooling oil with water includes (a) oil and water chambers alternately arranged to form a core portion; (b) a through hole formed in the core portion to allow an oil flow therethrough; (c) first and second oil passages communicating with the oil chambers; (d) a blocking plate for blocking a part of these oil passages; and (e) a cover member covering one side of the core portion. The through hole has one end as one of oil inlet and outlet, and the first oil passage has one end as the other. The cover member has an oil passage extending between the other end of the through hole and at least one of the other end of the first oil passage and an end of the second oil passage.
