Abstract

A heat exchanger includes a plurality of tubes, a pair of header pipes, partition walls, an inlet connector block and an outlet connector block. The plurality of tubes have one ends connected to one header pipe and other ends connected to the other header pipe. The header pipe internally has a pipe-inside flow-through bore. The partition wall is internally formed in each header pipe to divide the pipe-inside flow-through bore into two regions. Each header pipe has a block connector bore opening at an outer side wall opposing to an area to which the tubes are connected and opening to the pipe-inside flow-though bore by cutting out a portion of the partition wall. The inlet connector block is connected to the block connector bore of one header pipe to admit coolant to flow in. The outlet connector block is connected to the block connector bore of the other header pipe to permit coolant to flow out.

Dependent claims

A heat exchanger comprising:

a plurality of tubes internally having tube-inside flow-through bores;
a first header pipe comprising:
a first partition wall that is internally formed;
a first pipe-inside flow-through bore portion that is internally formed and divided into two regions by the first partition wall;
and
a first tube insertion bore portion formed on a first area of a side wall in slit shapes to accommodate first end portions of the tubes;
a second header pipe comprising:
a second partition wall that is internally formed;
a second pipe-inside flow-through bore portion that is internally formed and divided into two regions by the second partition wall;
and
a second tube insertion bore portion formed on a first area of a side wall in slit shapes to accommodate second end portions of the tubes;
a first connector bore portion formed on the side wall of the first header pipe at a second area opposing to the first area and on the first partition wall at an area opposing to the second area, and opening to the two regions of the first pipe-inside flow-though bore portion;
a second connector bore portion formed on the side wall of the second header pipe at a second area opposing to the first area and on the second partition wall at an area opposing to the second area, and opening to the two regions of the second pipe-inside flow-though bore portion;
an inlet connector block having one end portion accommodated in the first connector bore portion and permitting coolant to flow through the first pipe-inside flow-through bore portion;
and
an outlet connector block having one end portion accommodated in the second connector bore portion and permitting the coolant to flow out through the second pipe-inside flow-through bore portion
wherein the distal end surface of the end portion of the inlet connector block is closed, and the side wall of the end portion of the inlet connector block has a plurality of bore portions.
