Abstract
The invention discloses a plate-fin water heat exchanger for a gas water heater, which comprises a multi-channel parallel flow flat tube, a slotted fin, a partition plate, a cold water inlet pipe, a hot water outlet pipe, a collector pipe and a water tank shell, wherein the multi-channel parallel flow flat tube shows a serpentiform distribution, one end of the multi-channel parallel flow flat tube is tightly wound round the water tank shell and connected with the cold water inlet pipe and the other end is connected with the hot water outlet pipe; a plurality of slotted fins are arranged between all water channels of the multi-channel parallel flow flat tube; the multi-channel parallel flow flat tube is partitioned into an upper layer and a lower layer by the partition plate. The invention results in that the heat exchange efficiency of the water heat exchanger for the gas water heater is greatly improved through the improvement of type of the water heat exchanger for the gas water heater, which thereby reduces the gas consumption and reaches the purpose of saving energy, reducing the volume of the equipment and lowering the production cost.
Description
Technical field
The present invention relates to a kind of water heat transmission equipment, in particular, it is a kind of plate-fin water-to-water heat exchanger equipment that is used for gas heater.Be applicable to fields such as gas heater.
Background technology
China's gas heater follows external product basically in model change, the rare product of design fully voluntarily.Gas heater in the market develops rapidly towards the direction of big capacity, miniaturization, and water-to-water heat exchanger is one of critical piece of gas heater, is accounting for 1/3 of whole gas heater volume greatly, and it is very necessary therefore to produce compact heat exchanger.
What traditional gas heater generally adopted is that finned tube exchanger carries out enhanced heat exchange, and it is made of pipe or the external fin of elliptical tube usually, has big heat exchange area, but because the flow resistance of fin side is big, heat transfer property is had a significant impact.And closely be connected again between fin and the copper pipe, can not be gapped, more can not produce any surface resistance of heat transfers such as oxide layer, so water-to-water heat exchanger needs generally be coated with the last layer leypewter by the method that adopts the dip-coating leypewter on its surface.It is low that tin lead is put forth energy golden fusing point, easily fusing, evaporation, and to human body, big for environment pollution, even it is also easy to change in atmosphere, have a strong impact on presentation quality, and the lead layer between fin and the copper pipe is subjected to the erosion of high-temperature flue gas for a long time, slowly is oxidized to powder and comes off, the heat-transfer effect variation causes the decrease in efficiency of water heater.In addition, fin and water-to-water heat exchanger material are mainly red copper, and its oxidation under the effect of high-temperature fuel gas is quite fast, and the processing and manufacturing cost is higher.
Summary of the invention
The present invention has overcome existing equipment and technology above shortcomings, provides a kind of novel high-efficiency and energy-saving, volume is little, processing cost is low and the plate-fin water-to-water heat exchanger of the gas heater of environmental protection.
The present invention is achieved by following technical solution:
A kind of plate-fin water-to-water heat exchanger of gas heater, its structure comprise multichannel parallel stream flat pipe, slitted fin, dividing plate, cold water inlet, hot water outlet pipe, collector pipe and water tank shell at least; Described multichannel parallel stream flat pipe is snakelike distribution, and the one end twines and is close on the water tank shell, and links to each other with described cold water inlet, and the other end then links to each other with the hot water outlet pipe; Between each water stream channel of described multichannel parallel stream flat pipe some slitted fins are set; Described dividing plate is divided into the multichannel parallel stream flat pipe upper and lower two-layer, and cold fluid enters from lower floor's passage of multichannel parallel stream flat pipe, flows out from the upper strata tube passage by described collector pipe after heating.
Be arranged in series between each pipeline of described multichannel parallel stream flat pipe.
Described multichannel parallel stream flat pipe adopts aluminium, carbon steel, carbon steel composite panel or stainless steel material to make.
Carry out integral braze-welded the connection and sealing between described multichannel parallel stream flat pipe and the some slitted fins.
Compare with technology with existing equipment, the invention has the beneficial effects as follows:
1, owing to arranged some slitted fins between each flat tube of multichannel parallel stream flat pipe, play the increase heat exchange area, the heat transfer efficiency height reduces effects such as its spatial volume.
2, since between multichannel parallel stream flat pipe and the slitted fin by integral braze-welded welding, welding quality improves, thereby has reduced the extrusion process of heat exchanger tube fin, and is simple and compact for structure, is easy to process.
3, the water-to-water heat exchanger made from aluminium or stainless steel has not only been cancelled the process that adopts the dip-coating leypewter, and environmentally safe, handling ease, low cost of manufacture.
4, the multichannel parallel stream flat pipe twines and is close on the water tank shell, thereby has strengthened contact area, and this position fuel gas temperature height, has improved heat transfer efficiency greatly.
5, be arranged in series between the multichannel parallel stream flat pipe, improved water-to-water heat exchanger efficient.

Fig. 2 is a multichannel parallel stream flat pipe schematic diagram;
Fig. 3 is a multichannel parallel stream flat pipe schematic cross-section.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2 and shown in Figure 3, structure of the present invention comprises multichannel parallel stream flat pipe 1, slitted fin 5, dividing plate 8, cold water inlet 2, water inlet nut 3, hot water outlet pipe 7, water outlet nut 4 and the pipeline 6 that catchments at least.Described multichannel parallel stream flat pipe 1 is snakelike distribution, and the one end twines and to be close on the water tank shell, and links to each other with described cold water inlet 2, and the nut 3 of intaking is in order to fixing cold water inlet 2; The other end of described multichannel parallel stream flat pipe 1 then links to each other with hot water outlet pipe 7; Multichannel parallel stream flat pipe 1 is divided into upper and lower two-layer by dividing plate 8, cold fluid enters from lower floor's passage of multichannel parallel stream flat pipe 1, flows out from the upper strata tube passage by collector pipe 6 after heating; Be provided with between some slitted fins 5 and each passage between each water stream channel of multichannel parallel stream flat pipe 1 and be arranged in series, play the increase heat exchange area, the heat transfer efficiency height reduces the effect of its spatial volume.
