Claims

[Scope of utility model registration request]

(1) In a heat exchanger comprising a heat exchanger main body having a passage through which heated fluid flows, and a heat exchange pipe for circulating the heated fluid that contacts the outer wall of the main body, the outer wall of the heat exchanger main body While the groove portion into which the heat exchange pipe is closely fitted is molded as one piece, a small diameter portion is provided in a portion of the heat exchange pipe located in the groove portion on the upstream side of the heating fluid, and between the outer circumferential surface of the small diameter portion and the inner surface of the groove portion. A heat exchanger characterized by forming a gap.゛

(2) The heat exchanger body has heat transfer fins integrally molded and protruded from the inner wall of the passage, and the heat transfer fins have a portion located on the upstream side of the heated fluid cut away.Claims for Utility Model Registration The heat exchanger according to item 1.

(3) The heat exchanger according to claim 1 or 2, wherein the heat exchange pipe is inserted into the groove and then expanded except for the portion located upstream of the heated fluid so as to be brought into close contact with the groove. .

(4) The heat exchanger according to any one of claims 1 to 3, wherein the heat exchanger body is made of an extrusion molded body of a metal material.

(5) The heating fluid is combustion gas from a combustion device, and the heating fluid upstream side of the passage in the heat exchanger main body is the twisted one □
A heat exchanger according to any one of claims 1 to 4 of the utility model registration claims, which serves as a combustion space of a combustion apparatus.
