Abstract

The invention provides a heat exchanger for a double water cavity fuel oil heater. The heat exchanger for the double water cavity fuel oil heater comprises a outer water cavity and an inner water cavity, wherein the inner water cavity is arranged in the outer water cavity, the outer water cavity is connected in series with the inner water cavity by a water tube to form a steam loop; the outer water cavity consists of an outer sleeve of outer water cavity and an inner sleeve of the outer water cavity, an inner sleeve of the outer water cavity is sleeved in an outer sleeve of the outer water cavity, an outer sleeve of the outer water cavity is provided with a water inlet tube, a water outlet tube and a vent pipe, the tail part between the inner sleeve and the outer sleeve of the outer water cavity is provided with a water cavity caulking ring; the inner water cavity consists of an outer sleeve of the inner water cavity and an inner sleeve of the inner water cavity, the inner sleeve of the inner water cavity is sleeved in the outer sleeve of the inner water cavity, the inside of the inner sleeve of the inner water cavity is provided with a combustion taper cover, and the front end of the inner sleeve of the inner water cavity is provided with a positioning sleeve. The heat exchanger adopts double cavities which increase the heat exchange area of the heat exchanger and improve the thermal efficiency of a heater complete appliance; the inner water cavity is directly contacted with high-temperature combustion flame, so the phenomenon of bubbling fluidization ebullition in a water cavity generates, the heat exchange is strengthened, and the thermal efficiency of the fuel oil heater is improved by more than 10 percent.

Description

technical field [0001] The invention relates to a heat exchanger for a liquid fuel heater, belonging to the technical field of fuel heaters. Background technique [0002] As an independent heating device, the fuel heater has been widely used for heating in low-temperature environments and engine preheating for various transport machinery such as automobiles and ships. As a key component of a fuel heater, the heat exchanger has a significant impact on the heat exchange efficiency and other properties of the heater. At present, liquid fuel oil heaters all use spiral single water chamber heat exchangers for heat exchange. Because the heat exchange area of ​​this type of heat exchanger is restricted, the heat loss is still relatively large, that is, it cannot obtain a sufficiently high thermal efficiency under the same energy consumption. In particular, when the fuel heater is installed as an auxiliary system on a vehicle or device with limited length, width and height, it is ...
