Description
Technical field
The utility model belongs to boiler technology field, particularly a kind of heat exchanger for boiler.
Background technology
Heat exchanger is the equipment partial heat of hot fluid being passed to cold fluid, also known as heat exchanger.Current heat exchanger various informative, but its heat transfer effect differs greatly, the main difference be still embodied in material of these heat exchanger heat transfer effect quality.The heat exchanger structure of current market is single, and heat transfer effect is undesirable, and heat fully can not be converted use, makes a large amount of thermal waste.
In water channel simultaneously in heat exchanger, circulation has current, and current flow through water channel and realize heat exchange, if hot water flowing is too fast, then heat can be caused to transmit insufficient, hot water utilization rate is low, causes thermal loss; If hot water flows over slowly, then inefficiency can be caused.
Summary of the invention
The purpose of this utility model is the problems referred to above existed for existing heat exchanger structure, provides a kind of heat exchange effect better heat exchanger.
The purpose of this utility model realizes by following technical proposal: a kind of heat exchanger for boiler, it is characterized in that, it comprises a heat exchange water tank, this water tank is made up of multiple inlet unit, each inlet unit comprises housing, housing has two panels side plate opposed in opposite directions, heating chamber is formed between biside plate, the top of heating chamber is combustion chamber, the inwall of side plate is equipped with multiple heat exchange nail, flue is formed between heat exchange nail on biside plate, described side plate hollow, multi-disc partition is provided with in it, described partition is horizontal interval setting successively from top to down, water channel is formed between two neighbouring partitions, described water channel head and the tail are communicated with the heat exchanger channels forming S shape and spiral successively, the water inlet end of each heat exchanger channels is all communicated with a water inlet pipe, water side is all communicated with an outlet pipe, water tank is provided with the water inlet and delivery port that are communicated with respectively with above-mentioned water inlet pipe and outlet pipe.
Described heat exchange nail is cylindric, all perpendicular to side plate interior sides.Be convenient to the heat of all directions around heat exchange nail uniform pickup heat exchange nail.
The heat exchange nail of described heating chamber both sides is from top to bottom drawn close gradually in opposite directions.The loss of heat can be reduced like this, make heat energy obtain abundant conversion, reduce the wasting of resources.
Intensive layout is gradually followed closely from top to bottom in described heat exchange.
Combustion chamber is positioned at housing tip as a part for heating chamber, flame from top to bottom burns along flue, heat exchange nail is staggered and intensive layout can increase flame and contact area is followed closely in heat exchange greatly gradually, the heat that mostly burning is produced can by intensive heat exchange follow closely absorb conversion, minority is not moved to heating chamber bottom by the heat absorbing conversion, move upward again, absorbed conversion when secondary runs into heat exchange nail, greatly strengthen thermal conversion efficiency.Cold water flows through heat exchanger channels, follows closely and realizes heat exchange, flow out after completing heating from delivery port with the heat exchange of outside.
Described water channel broadens from top to down successively.Top water channel, near combustion chamber, belongs to high-temperature area, and narrower water channel can improve water velocity, is taken away by heat fast.The lower end of heating chamber is low-temperature region, and bottom water channel is wider, and water velocity is comparatively slow, increases the time of staying of water, fully absorbs heat, improves the thermal efficiency.
Described water channel inwall is provided with some spoilers, and spoiler is skewed, and the spoiler in two neighbouring water channels is oppositely arranged.Current by wall spoiler directionality choked flow effect, make current form tangential motion at wall in flow process.Take away water channel inwall deposition foreign material simultaneously, improve heat exchange efficiency.
Compared with prior art, the distance that this utility model can heat is larger, and thermal conversion efficiency is high, and heat exchange nail reasonable layout, result of use is good, again reduces manufacturing cost, is worthy of popularization.

Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Fig. 1 ~ Fig. 2, this device comprises a heat exchange water tank, and this water tank is made up of multiple inlet unit 12, and inlet unit 12 comprises housing 1, and housing 1 has two panels side plate opposed in opposite directions 2, forms heating chamber 5 between biside plate 2, side plate 2 hollow,
Shown in Fig. 3, multi-disc partition 6 is provided with in side plate 2 hollow chamber, described partition 6 is horizontal interval setting successively from top to down, water channel 7 is formed between two neighbouring partitions 6, described water channel 7 head and the tail are communicated with the heat exchanger channels forming S shape and spiral successively, the water inlet end of each heat exchanger channels is all communicated with a water inlet pipe 8, water side is all communicated with an outlet pipe 9, water tank is provided with the water inlet and delivery port that are communicated with respectively with above-mentioned water inlet pipe 8 and outlet pipe 9, the heat exchanger that after multiple inlet unit docking, formation one is larger.One block of side plate 2 can be shared between adjacent two inlet unit.
Be provided with multiple heat exchange nail 4 in heating chamber 5, heat exchange nail 4 can be used as heat accumulation member and uses, and carries out heat exchange with the cold water in water channel 7, and heat exchange is followed closely 4 symmetrical perpendicular to inside side plate 2, forms a flue 10 in the middle of relative heat exchange nail 4.Described heat exchange nail 4 different in size, therefore flue 10 is expanded gradually by lower to upper part, and the flue 10 on top is more open, and the air therefore entered is more, can form combustion chamber 3, meanwhile, heat exchange nail 4 intensive layout gradually from top to bottom.Combustion chamber 3 is positioned at housing 1 top as a part for heating chamber 5, flame from top to bottom burns along flue 10, heat exchange nail 4 is staggered and intensive layout can increase flame and 4 contacts area are followed closely in heat exchange greatly gradually, the heat that mostly burning is produced can absorb by intensive heat exchange nail 4 conversion, minority is not moved to heating chamber 5 bottom by the heat absorbing conversion, move upward, secondary runs into when heat exchange follows closely 4 and is absorbed conversion, greatly strengthens thermal conversion efficiency again.Cold water flows through heat exchanger channels, follows closely 4 realize heat exchange with the heat exchange of outside, is flowed out after completing heating by outlet pipe 9 from delivery port.
Because top water channel 7 is near combustion chamber 3, belong to high-temperature area, narrower water channel 7 can improve water velocity, taken away by heat fast, and the lower end of heating chamber 5 is low-temperature region, if bottom water channel 7 is wider, then water velocity is comparatively slow, therefore needs water channel 7 to broaden gradually from top to down setting, increases the time of staying of water, abundant absorption heat, improves the thermal efficiency.The flow velocity that more change of a progress is upper and lower, need to arrange some spoilers 11 at top water channel 7 inwall, each spoiler 11 is skewed, and the spoiler 11 in two neighbouring water channels 7 is oppositely arranged.Current by wall spoiler 11 directionality choked flow effect, make current form tangential motion at wall in flow process.Take away water channel 7 inwall deposition foreign material simultaneously, improve heat exchange efficiency.
