Fire-retardant heat transmitter and heating device provided therewith

Abstract

The invention relates to a fire-retardant heat transmitter and a heating device provided therewith. The fire-retardant heat transmitter comprises a shell with an inlet and an outlet which are communicated with each other, the shell is provided with at least one heat-conducting plate, and the heat-conducting plate is provided with a plurality of fire-retardant parts which are arranged in a staggered way; and an airflow passage for communicating the inlet and the outlet is formed between the fire-retardant parts and the heat-conducting plate. By additionally arranging the fire-retardant heat transmitter at a combustion outlet of a combustor, and arranging the plurality of fire-retardant parts which are arranged in the staggered way on the fire-retardant heat transmitter, flue gas generated from the combustion in the combustor collides with the fire-retardant parts so as to transmit heat, quickly passes through the airflow passage between the fire-retardant parts and the heat-conducting plate after collision and is discharged from the outlet; the increase of the flue gas stroke is very limited, thus not obstructing flue gas from discharging, leading airflow to be always smooth, and not obstructing combustion; and flame of combustion can stay due to obstruction of the fire-retardant parts, thus increasing the heat exchange with the fire-retardant parts, fully utilizing afterheat of the flue gas and greatly increasing the heat exchange efficiency of the heating device.

Description

technical field [0001] The invention relates to a heat conduction device, more specifically, to a fire-stopping heat spreader and a heating device with the fire-stopping heat spreader. Background technique [0002] Some current heating equipment, such as food steam cabinets, water heaters, etc., usually use liquefied gas as fuel, burn to generate heat, heat the water pipes, thereby heating the water in the water pipes to generate hot water, steam, etc. The flue gas produced by combustion and exchanged with the water pipe is directly discharged into the environment. The heat exchange efficiency of the heating equipment with this structure is low, and the exhausted flue gas usually has relatively high heat. In order to improve the heat exchange efficiency, the existing method is to design the smoke exhaust pipe into a serpentine or labyrinth shape, so that the flue gas moves forward in a detour, thereby delaying and increasing the heat exchange time of the flue gas. However,...
