Description

Bionical central heat energy gas heater

The utility model relates to life and uses gas heater, relates to bionical central heat energy gas heater particularly.

Existing life nearly all is a single hose with gas heater, this single tube is welded on the copper sheet of an annular by spirality, water passes through in the spirality single tube, combustion gas is at toroidal helical shape single hose base burning, flame conducts to flowing water flow in single tube with heat by copper sheet, thereby makes water become hot water for uses such as people have a bath.But there are following many shortcomings in this water heater: (1) heat part reaches water in the single tube through copper sheet, and has the heat of considerable part to scatter and disappear by chimney; (2) periphery of annular copper sheet is an air, and the heat that the copper sheet of high temperature outwards distributes is wasted fully; (3) hydraulic pressure in the heat-exchange tube is with hydraulic pressure is consistent from the beginning, the excessive and explosion owing to pressure easily; (4) can not be used to boil water; Can only use and can not use under the condition of ceasing fire while burning when (5) having a bath, therefore gas poisoning takes place easily, safety coefficient be relatively poor; (6) shell damages easily owing to often bear the heat radiation of higher temperature and therefore causes waste gas and unburned carbon monoxide to the room internal leakage easily, thereby has the danger of gas poisoning.

The purpose of this utility model be to provide a kind of heat exchanger effectiveness higher, can be used as the manufacture hot water and boil water two kinds of purposes and also can behind the burned hot water under ceasefire conditions hot-water supply, guarantee can not cause the bionical central heat energy gas heater of gas poisoning.

The utility model can reach by following technical proposals:

At length explain structure of the present utility model and effect below.

(1) so-called central heat energy formula is meant that flame is in the middle body of inner bag water storage interlayer inwall, flame is except carrying out the heat exchange with heat-exchange tube, also the inwall with inner bag carries out heat exchange, therefore heat is wanted earlier to carry out heat exchange through several layers of heat-exchange tube, inner bag inwall and with the water of the inside, just there is little heat to scatter and disappear at last, thereby can improves heat exchanger effectiveness widely through chimney.

(2) what is called is bionical is meant that the blind pipe on the inner bag inwall is similar to the fine hair in the human small intestine, can increase heat exchange area significantly, thereby improve heat exchanger effectiveness.But its thickness and general heat-exchange tube are approximate.

(3) the normal pressure mouth at inner bag top communicates with atmosphere, therefore guarantees that this water heater can the explosion owing to hypertonia.

(4) inner bag inwall and the heat-exchange tube tube wall that flame is only logical with current are arranged contacts, owing to water is constantly taken away heat, so the problem that does not exist inner bag inwall or heat-exchange tube tube wall to be burnt out.

(5), therefore fully can be after burned hot water coal gas or oil gas be turned off again and have a bath, thereby guarantee can not cause gas poisoning owing to can store the have a bath hot water of usefulness of enough 1～3 people in the inner bag.

(6) owing to there being the normal pressure mouth, therefore can water is boiled, supply the people to drink as boiling water, thereby reach the purpose of one-machine-multi-function.

(7) to make the long and short purpose of alternately arranging of heat exchange blind pipe be to make that flame flow is circuitous to advance to the 2nd of technique scheme, thereby improve heat exchanger effectiveness.

(8) in the 4th～10 of the technique scheme heat-exchange tube cross section is defined as less acute angle or oval cross section is defined as major axis vertical towards lower angle, its objective is to reduce the resistance of heat-exchange tube fuel gas flow with horizontal plane.

Compare with water heater with the life of prior art, the utlity model has following beneficial effect:

(1) heat exchanger effectiveness obviously improves; (2) go for the manufacture hot water and the two kinds of purposes that boil water; (3) can under the condition of closing fuel gas source behind the burned hot water, have a bath, thereby guarantee to avoid gas poisoning; (4) heat exchange area of blind pipe is big, and its length do not have strict restriction, therefore processing or repair all more or less freely.
