Description
Technical field
The utility model relates to a kind of energy saver that adopts heat exchange principle, and particularly a kind of gas water-heater efficiency improves device.
Background technology
China is as the energy resource consumption big country in the world, and the energy in short supply become extremely urgent problem.But we are still very thin for the economy consciousness of the energy at present, and the many energy still at invisible waste, and many equipment still obtains economic benefit in a large amount of consumes energy.The universal gas heater that uses in big city promptly is a typical case now.
The operation principle of the gas heater of use is at present: combustion gas sprays and burning by gas nozzle, and the heat that produces that burns heats the cold water that flows through in the water heater by heat exchange and hot conduction, and it is for people to use to make cold water be heated back outflow water heater.The waste gas that burning produces is discharged by the exhaust opening of gas heater.
In actual use, gas heater generally following situation can occur: in summer, when the water temperature knob of water heater is adjusted to low-grade position, can feel also that sometimes water is very boiling hot.But in winter, particularly temperature is lower than sub-zero the time, even will regulate the water temperature knob to maximum, also can not feel warm sometimes.Such problem appears, mainly be that factor by following two aspects causes: the one, winter is different with the water temperature of the running water that enters gas heater summer, and the water temperature of running water is low as winter, generally about 7 ℃, and summer running water the water temperature height, generally about 25 ℃.The 2nd, the nominal of gas heater is fixed, as according to regulation among GB6932-86 " domestic gas instantaneous water heater " and the GB6932-94 " domestic gas instantaneous water heater ": the number implication that rises of gas heater nominal is: in one minute, the big fire amount of water heater can improve 25 degrees centigrade with the X premium on currency, claim that then gas heater is that X rises water heater.Implication as 10 liters of water heaters is exactly in one minute, and the big fire amount of water heater can improve 25 degrees centigrade with 10 premium on currency.If use the gas heater of big nominal, even the water temperature knob is adjusted to deep low gear, water is also very boiling hot.And use the gas heater of little nominal, the low excessively situation of water temperature can appear again in winter.Use the gas heater of big nominal in addition, not energy-conservation yet.
By actual detected, it is found that the temperature of the waste gas that gas heater is discharged is very high, heat is not fully absorbed by water, so causes the waste of energy yet.
Therefore, the gas heater that how to solve certain nominal is when using winter, and water temperature can reach instructions for use, can reach requirements of saving energy again simultaneously, is the target that people pursue always.Some technical staff just tries every possible means on raising enters the inflow temperature of gas heater, as in winter, adopts electric heater unit to improve the water temperature of running water, makes the leaving water temperature of gas heater of certain nominal reach the requirement of use.But such method can not energy savings.
Summary of the invention
The utility model purpose is to provide a kind of simple in structure, easy to use, energy-conservation gas water-heater efficiency to improve device, this gas water-heater efficiency improves device can make full use of the waste gas residual heat that the gas heater burning produces, improve the temperature of the running water that enters gas heater effectively, the gas heater that makes certain nominal is when using winter, and its leaving water temperature reaches the requirement of use.
The purpose of this utility model can be achieved through the following technical solutions:
Gas water-heater efficiency improves device, comprise a heat exchange casing, upper and lower case face at the heat exchange casing respectively has the waste gas import and export, in the heat exchange casing, be provided with the outer tube wall of tortuous water pipe and water pipe and the air flue of the internal box wall formation of heat exchange casing, described water pipe to extend heat exchange box respectively into and out of water end (W.E.) external and connect the water inlet of running water pipe and gas heater respectively, the import and export of described waste gas be air flue into and out of end.
In actual use, gas water-heater efficiency of the present utility model is improved the exhaust opening that exhaust gas inlet on the heat exchange casing of device directly is enclosed within gas heater, connect smoke pipe to outdoor at waste gas outlet.Simultaneously, water pipe connect the water inlet of running water pipe and gas heater respectively into and out of water end (W.E.) by pipeline, after opening gas heater, the high-temp waste gas that the gas heater fuel gas buring produces enters into air flue in the heat exchange casing by exhaust opening, and discharge along the waste gas outlet that moves on the heat exchange casing of air flue complications, simultaneously, running water enters in the water pipe by water inlet end, in water pipe, flow circuitously, to the water side inflow gas heater of water pipe, heat.The waste gas of high temperature is in the flow process of heat exchange casing like this, can carry out heat exchange with the water that flows through in the water pipe fully by the tube wall of water pipe, the water that flows through in the water pipe is preheated, thereby improved the water temperature from the beginning that flows in the gas heater, the gas heater that makes certain nominal is when using winter, and its leaving water temperature reaches the requirement of use.
Further specify energy-saving effect of the present utility model below by the actual detected effect:
