Detailed description of the invention
Refer to Fig. 1, the application provides a kind of gas heater, and this gas heater comprises body 1, blower fan 2, burner (fire row) 3 and a heat exchanger 4.This body 1 is a hollow housing, and it is inner that blower fan 2, burner 3 and heat exchanger 4 are arranged at body 1, and the position that blower fan 2, burner 3 and heat exchanger 4 are arranged does not limit, can because of in requisition for and changed.In the present embodiment blower fan 2, burner 3 and heat exchanger 4 from bottom to top sequentially to be arranged at body 1 inner, burner 3 is between blower fan 2 and heat exchanger 4.After burner 3 is lighted, burner 3 can produce the burning gases of high temperature, and burning gases are pushed upwardly and send, contacts combustion gases heat exchanger 4, so as to carrying out the operation of heat exchange, make the water flowed through in heat exchanger 4 can be heated to high temperature from normal temperature, then row discharge hot water use.
This heat exchanger 4 is connected with cold water pipeline 5 and a hot water line 6, and cold water pipeline 5 and hot water line 6 form a water passage, and heat exchanger 4 is connected between cold water pipeline 5 and hot water line 6.One end of this cold water pipeline 5 has a cold water inlet 51, can be connected to suitable water source, for inputting the cold water for heating, this cold water pipeline 5 also can be provided with a water yield detector 7, in order to detect amount of inlet water.One end of this hot water line 6 has a hot water outlet 61.This gas heater can comprise a control unit 8 further, device such as blower fan 2 grade electrically in control unit 8 so that utilize this control unit 8 control combustion situation produce hot water.
Please refer to Fig. 1 and Fig. 2, this heat exchanger 4 has multiple spaced fin 41 and is arranged in a water pipe 42 of those fins 41, fin 41 and water pipe 42 are made with High heat conduction material (as copper etc.), water pipe 42 one end is connected to cold water pipeline 5, the other end is connected to hot water line 6, and water pipe 42 is connected between cold water pipeline 5 and hot water line 6.Can be inputted the cold water of wish heating by cold water inlet 51 and cold water pipeline 5, make cold water be delivered to heat exchanger 4, cold water enters heat exchanger 4 and carries out heat exchange, then exports hot water by hot water line 6 and hot water outlet 61 again, uses for user.
Referring again to Fig. 3 and Fig. 4, this heat exchanger 4 is a breach formula fin design, and the roughly rectangular lamellar body of those fins 41, fin 41 is respectively provided with multiple perforation 411, and those perforation 411 can be distributed in fin 41 first half, Lower Half and middle etc.This water pipe 42 is arranged in the perforation 411 of those fins 41, also can be welded to connect between water pipe 42 and perforation 411.Those fins 41 are main by the heat absorption of below stove fire, make fin 41 produce high temperature and high heat, to carry out the effect of heat exchange with the water in water pipe 42, make water pipe 42 can discharge hot water and use.
On those fins 41, punching is formed with multiple protuberance (or claiming salient point) 412 respectively, and those protuberances 412 can protrude from the one side of fin 41, make protuberance 412 have suitable height, make it form unidirectional breach formula protuberance.Certainly those protuberances 412 also can protrude from the two sides of fin 41, make it form two-way breach formula protuberance.In the present embodiment protuberance 412 is arranged at the first half and the middle of fin 41, but does not limit, protuberance 412 also can be arranged at the Lower Half of fin 41, or position suitable on whole fin 41.Each fin 41 can be provided with the protuberances 412 of two to six rows, protuberance 412 quantity of often arranging is three to eight etc.
Those protuberances 412 can be rectangular, trapezoidal etc., and those protuberances 412 are all in trapezoidal in the present embodiment, the contiguous perforation 411 in trapezoidal protuberance 412, coordinates perforation 411 to design in trapezoidal, to increase its area.The lower edge of protuberance 412 and can be formed with air intake 413 and a gas outlet 414 between upper limb and fin 41 further respectively, protuberance 412 is connected with fin 41 with both sides, and the one or both sides of protuberance 412 are oblique setting.Because the structure of protuberance 412 is roughly same as the prior art, and the application does not limit the structure of protuberance 412, therefore is no longer repeated.
The application can be defined as follows further:
Two often adjacent fin pitch are Fp, and water pipe caliber (or punch inside diameter) is d
h, descend the protuberance of row to be SL apart from below place water pipe upper limb vertical range most, protuberance width is Sw, and protrusion height is Sh.
If meet following relationship condition, then can reach the preferably thermal efficiency:
Sh/Sw＝0.05～0.3，Sh/Fp＝0.3～0.8，Sw/Fp＝2～8。
If meet following relationship condition, then can reach the better thermal efficiency:
SL＝(0.5～2.5)d
H。
If meet following relationship condition, then can reach the best thermal efficiency:
Sh/Sw＝0.13，SL＝1.4d
H，Sh/Fp＝0.5，Sw/Fp＝3.9。
Be with, according to the particular design of above-mentioned heat exchanger, through experimental result, when the application's water heater such as inputs (Input) power 33.1kw, with the heat exchanger of the heat absorption fin of formed objects and sheet number for benchmark, its thermal efficiency can be promoted to about 82%, the best can be promoted to 83.3%, make water heater can reach the preferably thermal efficiency, and then the time of heating can be reduced, avoid the waste causing the gas energy.
Only the foregoing is only the preferred embodiment of the application, be not intended to the scope of patent protection of limiting to the application, therefore the equivalence change of such as using present specification and accompanying drawing content to do, be all in like manner all contained within the scope of the rights protection of the application, close and give Chen Ming.
