Abstract
The utility model discloses a heat exchanger applied in a forced-pumping semi-closed type gas water heater, which comprises a heat exchanger chamber, water inlet pipes, a heat exchanger and a water outlet pipe. The upper end of the heat exchanger chamber is connected with the heat exchanger. The water inlet pipes are tightly wound on the heat exchanger chamber. The heat exchanger chamber which is rectangular has transitional arced edges. The heat exchanger provided in the utility model and overcoming the defects in the prior art has the characteristics of simple structure, installing and dismounting convenience, and installing space conservation. The heat exchanger in the utility model is suitably applied in household rapid gas water heaters or dual-purpose furnaces.
Description
[technical field]
The utility model relates to a kind of heat exchanger that is used for taking out by force the semi-hermetic type gas heater.
[background technology]
The heat exchanger that is used for taking out by force the semi-hermetic type gas heater at present is connected through flange with the combustion chamber mostly, and flanged plate promptly respectively is set on heat exchanger cavities and combustion chamber, couples together two flanged plates through screw or screens mode again.This connected mode sealing, bonding strength are relatively good, change but be not easy to mounting or dismounting, and flanged plate take more space, and production process is many, and cost is higher.
The utility model is being made in such cases.
[utility model content]
The utility model purpose is in order to overcome the weak point of common heat exchangers, and provides a kind of simple in structure, is convenient to mounting or dismounting, saves the heat exchanger of installing space, is applicable to domestic gas instantaneous water heater or dual-purpose stove.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposal:
A kind of heat exchanger that is used for taking out by force the semi-hermetic type gas heater; Include heat exchanger cavities, water inlet pipe, heat exchanger, outlet pipe; It is characterized in that described heat exchanger cavities upper end is connected with heat exchanger, water inlet pipe closely is wrapped on the heat exchanger cavities.
Aforesaid a kind of heat exchanger that is used for taking out by force the semi-hermetic type gas heater is characterized in that described heat exchanger cavities is the rectangle cavity, and its seamed edge is with arc transition.
Aforesaid a kind of heat exchanger that is used for taking out by force the semi-hermetic type gas heater is characterized in that described heat exchanger cavities is provided with the lower surface that is connected with the combustion chamber, and the periphery fillet expansion of described lower surface meets at right angles.
Aforesaid a kind of heat exchanger that is used for taking out by force the semi-hermetic type gas heater is characterized in that periphery is provided with through hole in described lower surface.
Aforesaid a kind of heat exchanger that is used for taking out by force the semi-hermetic type gas heater is characterized in that described through hole is the strip hole.
The utility model is compared with common semi-hermetic type heat exchanger, and its difference is:
1, the end face that is connected with the combustion chamber of heat exchanger expands rectangularity, and in rectangular periphery the strip installing hole is set, and the combustion chamber directly embeds in the heat exchanger cavities, again through being threaded;
2, simplify heat exchanger, combustion chamber manufacture craft, reduce cost of manufacture;
3, combustion chamber, burner are prone to the mounting or dismounting replacing;
4, reduce heat exchanger assembling space, thereby reduce machine volume.

Fig. 2 is the stereogram of the utility model;
Fig. 3 is the stereogram of the heat exchanger cavities of the utility model;
Fig. 4 is the stereogram of common heat exchangers and adpting flange.
[specific embodiment]
Below in conjunction with accompanying drawing the utility model is described in detail:
Like Fig. 1, shown in 2, a kind of heat exchanger that is used for taking out by force the semi-hermetic type gas heater includes heat exchanger cavities 1, water inlet pipe 2, heat exchanger 3, outlet pipe 4.Heat exchanger cavities 1 upper end is connected with heat exchanger 3, and lower surface 12 is connected with the used combustion chamber of overheavy firing, and water inlet pipe 2 closely is wrapped on the cavity 1.Running water flow through water inlet pipe 2, heat exchanger 3 and outlet pipe 4 are accomplished heat transfer process.
As the optimal way of present embodiment, end face 12 peripheries that are connected with the combustion chamber in said heat exchanger cavities 1 are provided with through hole 14, through the mode that is threaded heat exchanger and combustion chamber are coupled together.
As the optimal way of present embodiment, said through hole 14 is the strip hole, uses the strip hole can allow certain rigging error, reduces machining accuracy.
