Abstract

The invention relates to a heat exchanger comprising a combustion chamber, a high-temperature smoke delivery pipe, multiple jacketed pipes and a condensation smoke discharge pipe. The high-temperaturesmoke delivery pipe, the multiple jacketed pipes and the condensation smoke discharge pipe are arranged in the circumferential direction of the combustion chamber. The combustion chamber communicateswith the high-temperature smoke delivery pipe. The multiple jacketed pipes sequentially communicate. Each jacketed pipe comprises an inner pipe, an outer pipe arranged outside the inner pipe in a sleeving manner, and an end cover. The high-temperature smoke delivery pipe communicates with one jacketed pipe, and the condensation smoke discharge pipe communicates with another jacketed pipe. By means of the heat exchanger, the heat exchange efficiency can be improved, the ignition success rate can be ensured, the structure is reasonably distributed, the device space occupation rate is decreased,and the device economy is improved.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a heat exchanger. Background technique [0002] Fuel boiler is a kind of boiler widely used in daily life or industrial production. It uses the heat energy released by fuel combustion to heat water to the rated temperature, so as to provide heating for places in need or provide hot water for industrial production. [0003] The internal heat exchange method of traditional fuel boilers is commonly known as the water-in-fire form, which can only absorb heat on one side, with a large outward heat dissipation area and a large equipment volume. [0004] Due to the unreasonable structure of the heat exchanger in the existing fuel boiler, there are problems such as easy ignition failure, low heat transfer efficiency, large device volume and high cost. If the thermal resistance of the heat exchanger is too large, it will cause explosion and other problems that threaten the structur...
