Abstract

The utility model relates to a hot-water stove, especially, the utility model provides a normal pressure internal combustion fuel oil hot-water stove. The utility model is characterized in that a convection box is arranged in a water jacket, and the upper end of the convection box penetrates through the housing of the water jacket; more than two layers of transversal flushing tube bundles are arranged in the convection box, the two ends of each root of the flushing tubes are fixedly connected with the convection box to form an internal circulation passage arranged in the water jacket, a stove core is connected and communicated with a horizontal flue, and the convection box penetrates through the lower end of the horizontal flue. The utility model has the advantage of high thermal efficiency; besides, the time of the trouble-free operation of the utility model is long.

Description

Water heater

The utility model provides a kind of water heater, and a kind of normal pressure internal combustion oil gas water heater particularly is provided.

Existing normal pressure internal combustion oil gas water heater, the general pipe with spiral pipe that adopts vertical smoke pipe bundle or vertically coil of heat exchange structure in it, they are the parallel baffled mode, wherein: the former is because of the existence of laminar sublayer, cause the heat exchange weak effect of convection heating surface, the thermal efficiency of water heater is lower, and the latter exists the defective that few, the easy obstruction of water capacity is burnt out, and higher to requirements in water quality, cause shorten the non-failure operation time of water heater; In addition, existing normal pressure internal combustion oil gas water heater generally adopts dried back structure, and like this, rear wall plate directly stands high temperature and easily burnt out, and causes further shorten the non-failure operation time of water heater.

The purpose of this utility model is to provide a kind of thermal efficiency height, non-failure operation time long water heater.

The purpose of this utility model is achieved through the following technical solutions:

The water heater that the utility model provides, be provided with insulation material between water jacket and the shell, flue places among the water jacket and the upper end passes shell, water pipe more than 2 and water jacket UNICOM, its design feature is: the convection current case places among the water jacket and the upper end passes shell, be provided with the transversal flow tube bank more than two layers in the convection current case, the two ends of every flush pipe are the affixed and interior inner cycle channel of formation water jacket with the convection current case all, and flue and convection current case are by the horizontal flue UNICOM of lower end.

According to water heater provided by the utility model, the interior wet back of the body case in addition of horizontal flue, this wets to carry on the back and passes through VERTICAL TUBE UNICOM between case and the water jacket, water inlet pipe and the wet case UNICOM of carrying on the back.

By above technical scheme as seen, the utility model in use, flame in the flue is introduced in the horizontal flue, enter in the convection current case through the afterburnt flue gas, and flue gas vertically passes successively from bottom to up to be discharged in the atmosphere after the transversal flow tube bank more than two layers again and goes, and this heat exchange structure makes flue gas realize the transversal flow to above-mentioned tube bank, and the disturbance of flue gas is obvious, cause the heat exchange effect of convection heating surface obviously to strengthen, effectively improved the thermal efficiency of water heater; As mentioned above as can be known; flame in flue enters in the process of after-flame in the horizontal flue; wet back of the body case can absorb a part of heat of flame; like this, both increase the radiation heating-surface of water heater, helped to improve the thermal efficiency of water heater; avoided rear wall plate directly to stand high temperature again; make rear wall plate be subjected to effectively protection and difficult being burnt out, like this, prolonged the non-failure operation time of water heater.In sum, the utlity model has the long advantage of thermal efficiency height, non-failure operation time.
