Description
Technical field
The utility model is related to gas heater technical field more particularly to the shells of condenser.
Background technology
Existing condensing gas-fired fast water heater, condenser mostly use metal plate and weld to form seal cavity, in seal chamber
Flue gas flow channel design is carried out again in vivo, is limited to the formability of metal plate, and flue gas flow channel cannot be excessively complicated, therefore, most of
After condenser enters condenser using flue gas at present, enter heat exchanger from condenser shell lower space, flue gas passes through heat exchanger
It is expelled directly out after heat exchange, but flue gas will produce condensed water to the cold in heat transfer process, condensed water is dripped along heat-transfer surface along gravity direction
It falls, when condensed water drippage direction is opposite with flue gas flow direction, is easy in heat-transfer surface formation liquid film, flue gas cannot directly and heat-transfer surface
Contact, the heat exchange efficiency of heat exchanging body certainly will reduce.
Utility model content
In view of this, the utility model aim primary and foremost purpose be just to provide a kind of condenser casing aim to solve the problem that it is existing
Flue gas flow direction drips direction on the contrary, the heat exchange efficiency brought reduces with condensed water in condenser.
