Description
Technical field
The utility model relates to the water-water heat exchanger and the steam water heat exchanger of the domestic hot-water supply system in a kind of heat exchange element and the building water supply and drainage industry, the instant heating volumetric heat exchanger of particularly a kind of bellows heat exchange element and this element of employing.
Background technology
Heat exchange element is a kind of widely used heat-exchanging part, at present, the operating position of the volumetric heat exchanger from the hot water supply system, heat exchange element mainly contains two kinds: the one, carbon steel pipe, the 2nd, red copper or brass tube.
Carbon steel pipe is the volumetric heat exchanger of heat exchange element, and because of tube wall very thick (being generally 2mm-3.5mm), heat transfer coefficient only is 800Kcal/m
2.h. ℃ about, and heat exchanger wall scaling very easily, heat transfer coefficient reduces more behind the scaling, only is 500Kcal/m
2.h. ℃ about, the serious reduction being heated exerting oneself of domestic hot-water, and heat exchanger volume is big, heavy.
With red copper or brass is the volumetric heat exchanger of heat exchange element, and thickness of pipe wall is generally 1.5mm-2mm, and heat transfer coefficient is slightly higher than carbon steel pipe heat transfer element, is 900Kcal/m
2.h. ℃.But it is big also to exist heat exchanger volume, the defective of heavy.
On the structure of volumetric heat exchanger, there are two kinds: the one, vertical volumetric heat exchanger, the 2nd, horizontal volumetric heat exchanger.
The heat exchanger of above-mentioned two kinds of structural shapes is monodromy heat pipe bundle, and the heat exchanger tube in the insertion tank body is divided into again is not with overcoat cartridge type and band overcoat cartridge type, as shown in Figures 1 to 4, the heat form of the volumetric heat exchanger shown in Fig. 1,2 is that the hot water that adds of high temperature is walked in the heat exchanger tube, low temperature in the tank body is heated water directly to be heated, its shortcoming is because to be heated the flow velocity of water in jar very slow even do not flow sometimes, so its heat exchange mode is mainly heat conduction heat exchange, and efficient is very low.
The heat form of the volumetric heat exchanger shown in Fig. 3,4 is that high temperature adds hot water and walks in the heat exchanger tube, the water that is heated of low temperature is walked in the outer sleeve, then enter tank body again, since be heated water at the heat exchanger tube surface velocity greater than at the flow velocity that is heated water shown in Fig. 1,2, its heat exchange mode is two kinds of convection current and heat conduction, thus heat transfer efficiency than among Fig. 1,2 not the heat exchanger with outer sleeve increase.But it is only applicable to water consumption less than 15 tons/hour, can't satisfy a large amount of consumptions of concentrating when using that are heated water.
In addition, the heat exchanger of above-mentioned two kinds of structures can't satisfy the working condition of following heat supply network, that is: a water temperature (adding hot water) difference is bigger, and flow is less, require secondary water-supply (being heated water) temperature than high ten degree of primary water temperature about (domestic hot-water: 70/40 ℃ 12/55 ℃).Under this special working condition, above-mentioned known heat exchanger often causes the primary water temperature can not fall, and therefore the phenomenon that secondary water-supply temperature liter does not get on is unsuitable for using under this working condition.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of bellows heat exchange element and adopts the instant heating volumetric heat exchanger of this element, heat exchange element wherein of the present utility model is a bellow-shaped, the instant heating volumetric heat exchanger can solve the problem that above-mentioned existing similar technology exists, heat-exchanging tube bundle is two groups of eclipsed forms, and every group of heat-exchanging tube bundle in the insertion tank body all has outer sleeve, can reach the purpose that the separate unit heat exchange area is big, heat transfer coefficient is high.And can satisfy the requirement that the primary water temperature is higher than the secondary water-supply temperature.
For this reason, the utility model provides a kind of bellows heat exchange element, and its outer wall is corrugated vertically, and this heat exchange element is for to be made of stainless steel tube, and pipe thickness is 0.5-0.8mm.
A kind of instant heating volumetric heat exchanger that adopts above-mentioned bellows heat exchange element, this heat exchanger has a housing, be provided with on the housing top and be heated water out, safety-valve, be provided with sewage draining exit and fixture, in housing, be provided with the heat exchanger components of two groups of series connection in the housing bottom.
Aforesaid instant heating volumetric heat exchanger, described heat exchanger components has a heat exchange element housing, on the heat exchange element housing, be provided with and add hot water inlet and add hot water outlet, the first heat exchange element housing add the hot water outlet that adds that hot water inlet connects the second heat exchange element housing.
Aforesaid instant heating volumetric heat exchanger, the first heat exchange element housing and the second heat exchange element housing are provided with heat-exchanging chamber, heat-exchanging chamber with add hot water outlet and add hot water inlet and be tightly connected; One interconnecting part is connected the heat-exchanging chamber of first heat exchange element with second heat exchange element.
Aforesaid instant heating volumetric heat exchanger, a pipeline connects the heat-exchanging chamber of the heat exchanger shell and second heat exchange element.
Aforesaid instant heating volumetric heat exchanger is provided with the bellows heat exchange element in described heat-exchanging chamber.
Aforesaid instant heating volumetric heat exchanger, first heat exchange element are provided with and are heated water inlet, and second heat exchange element is provided with an exhaust outlet.
Aforesaid instant heating volumetric heat exchanger, described heat exchanger shell can be for horizontal or vertical.
Aforesaid instant heating volumetric heat exchanger, the second heat exchange element housing are arranged on the first heat exchange element housing upside.
