<p><P>PROBLEM TO BE SOLVED: To achieve a compact fluid heater excellent in heat transfer efficiency and having a simple structure, the fluid heater needing no large scale facility such as a burning gas passage or a smoke tube. <P>SOLUTION: The problem is solved by providing a heat exchanger with a burner for heating fluid as follows. The heat exchanger with the burner for heating fluid includes: a heat-transfer tube having a closed distal end part, an opened base end part, and a burned gas exhaust port between the distal end part and the base end part; the burner which is mounted in the heat-transfer tube in a state that at least the distal end part is inserted in the heat-transfer tube from the opened base end part of the heat-transfer tube, thereby forming a burning gas channel from a distal end part of the burner to the burned gas exhaust port between an outer peripheral surface of the burner and an inner circumferential surface of the heat-transfer tube; and heat conduction bodies which are arranged in the burning gas channel and contact to the inner circumferential surface of the heat-transfer tube. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
