Abstract
The heat exchanger has a zig-zagged liquid-flowing passage and an overflowed-liquid escaping conduit. When an excessive amount of cooling water is supplied to the heat exchanger, a part of cooling water flows into the overflowed-liquid escaping conduit through a dam formed between the liquid-flowing passage and the escaping conduit. The heat exchanger is formed by assembling a plurality of heat exchanging partition plates formed by molding. The heat exchanging partition plates have the same shape and the same dimensions, and they are easily engageable with and detachable from each other.
