Abstract

A gas heater pertains to a heating device, which is composed of a housing, a multi-end burner, heating tubes, a radiator, a blower and an air extracting pump. The housing is segmented into a heating room with a hot air exit on the top and a combustor with the multi-end burner on the upper part and the air extracting pump on the lower part. The heating tubes, S-shaped metal tubes, are arranged side by side on the top of the heating room. The front ends of the heating tubes are pumped into the heating room and corresponded to the flame nozzle on the multi-end burner. Radiators are provided on he heating tubes whose back ends are combined together and connected with the air intake of the air extracting pump inside the combustor. The blower is arranged on the lower part of the heating room.

Description

Gas heater

The utility model is a kind of Gas heater, belongs to heating system.

In the winter of northern China many employings hot-water heating or the heating of steam heating device.Between the timing heating period, it can satisfy the demand of people's heating generally speaking.But the time marquis of changing according to the season, just no longer heated in the place mostly, and the weather of northern area is also colder at this moment, still needs heating, and most of like this people can only stand cold.Do not heat in most areas in south.But weather is also colder in the winter time, and people also need suitable heating.In addition, adopt hot-water heating or steam heating device also can pollute to environment.Gas-heating is a kind of more satisfactory heating system.But the Gas heater thermal efficiency that uses is lower at present, causes the waste of the energy.

The purpose of this utility model provides the higher Gas heater of a kind of thermal efficiency.

Gas heater of the present utility model is made of shell, bull burner, heating tube, radiator, air blast and aspiration pump; Shell is divided into two parts, i.e. heating clamber and combustion chamber, and the top of heating clamber has hot-blast outlet, and the bull burner is equipped with on the top in the combustion chamber, and aspiration pump is equipped with in the bottom, and the gas outlet of aspiration pump is led to outside the housing; Heating tube is to curve snakelike metal tube, several heating tubes are contained in the top of heating clamber side by side, its front port feeds the combustion chamber, corresponding with the flame nozzle on the bull burner, radiator is equipped with at the rear portion of heating tube, and port is associated in together thereafter, communicate with the air inlet of aspiration pump in the combustion chamber, radiator also can be contained in the top or the middle part of heating tube, and air blast is contained in the bottom of heating clamber, and its air outlet is facing to heating tube.

The working method of this Gas heater: Gas heater is placed on balcony or in the kitchen.Aspiration pump is from the rear port pump drainage gas wherein of heating tube, makes to form air-flow and certain negative pressure in the heating tube, force flame on the burner from the front port of heating tube to internal combustion, heating heating tube and radiator.Air blast blows to air on radiator and the heater, through heat exchange, air heat is formed hot blast, in hot-air mouth on the housing and pipeline inlet chamber.Heating tube and burning chamber waste gas are discharged to outdoor by aspiration pump and pipeline.

Use this Gas heater thermal efficiency height, can reach more than 90%.Because this Gas heater is placed on work outside the room, it can not take people's indoor activity space, and safer.

Fig. 1 is this Gas heater general assembly generalized section;

Fig. 2 is this Gas heater partial cutaway schematic.

Embodiment (seeing Fig. 1,2):

Gas heater of the present utility model is made of shell 1, six burners 8, heating tube 2, radiator 3, air blast 4 and aspiration pumps 6; Shell 1 is divided into two parts, i.e. heating clamber 5 and combustion chamber 7, and the top of heating clamber 5 has hot-blast outlet 10, and combustion chamber 7 is positioned at the upper lateral part of heating clamber 5, and bull burner 8 is equipped with on its top, and aspiration pump 6 is equipped with in the bottom, and the gas outlet of aspiration pump 6 is led to outside the housing 1; Heating tube 2 is for curving snakelike metal tube, six heating tubes 2 are contained in the top of heating clamber 5 side by side, its front port feeds in the combustion chamber 7, corresponding with six flame nozzles on six burners 8, the radiator 3 that is made of one group of fin is equipped with at the rear portion of heating tube 2, and heating tube 2 rear ports are associated in together, communicates with the air inlet of aspiration pump 6 in the combustion chamber 7, air blast 4 is contained in the bottom of heating clamber 5, and its air outlet is facing to heating tube 2 and radiator 3; 9 is flame among the figure.

Claims

1. a Gas heater is made of shell, bull burner, heating tube, radiator, air blast and aspiration pump; It is characterized in that shell is divided into two parts, i.e. heating clamber and combustion chamber, the top of heating clamber has hot-blast outlet, and the bull burner is equipped with on the top in the combustion chamber, and aspiration pump is equipped with in the bottom, and the gas outlet of aspiration pump is led to outside the housing; Several heating tubes are contained in the top of heating clamber side by side, its front port feeds the combustion chamber, corresponding with the flame nozzle on the bull burner, radiator is equipped with at the rear portion of heating tube, thereafter port is associated in together, communicate with the air inlet of taking out pump in the combustion chamber, air blast is contained in the bottom of heating clamber, and its air outlet is facing to adding pipe.
