Abstract
The invention relates to a cast aluminum heat exchanger of a gas-fired boiler. The cast aluminum heat exchanger of the gas-fired boiler comprises a front module, a middle module and a back module, wherein a water channel is arranged in each module, a flue is formed between adjacent modules, the front module, the middle module and the back module are formed through die casting, each water channel consists of a main water inlet channel, a heat exchange water channel and a main water outlet channel, the heat exchange water channel in each module is communicated with the main water inlet channel and the main water outlet channel, the main water inlet channels of adjacent modules are communicated and the main water outlet channels of adjacent modules are communicated. Since the cast aluminum heat exchanger is formed by adopting the die casting process instead of the sand casting process, the production efficiency is improved and the manufacturing cost is reduced; since the main water inlet channels, the heat exchange water channels and the main water outlet channels are all built in the modules, the size of the heat exchanger is reduced, the assembling structure is simplified and the installation steps and the material costs of the water channels are reduced.
Description
Technical field
The present invention relates to a kind of gas fired-boiler cast aluminium heat exchanger, be particularly useful for the gas fired-boiler gas utensils such as hot gas water heater for heating.
Background technology
In the prior art, Chinese patent application document CN103542526A discloses a kind of cast aluminium heat exchanger for gas-fired water heater, comprise left heat exchange end plate, right heat exchange end plate, stage casing heat exchanger plates and water inlet pipe, outlet pipe, on left heat exchange end plate, right heat exchange end plate, stage casing heat exchanger plates, be respectively equipped with water stream channel, water inlet pipe is communicated with the water inlet of above-mentioned each water stream channel, outlet pipe is communicated with the delivery port of above-mentioned each water stream channel, above stage casing heat exchanger plates be clamped between left heat exchange end plate and right heat exchange end plate and with its formation one.Although the versatility of the cast aluminium heat exchanger that it can promote, the required power of the free assembling combination of energy while making cast aluminium heat exchanger applications, but the assembling of water inlet pipe, outlet pipe trouble, overall volume is larger, in addition, cast aluminium heat exchanger generally adopts the moulding of sand casting process, also has processing trouble, efficiency is low, high in cost of production problem.For overcoming these defects, spy develops gas fired-boiler cast aluminium heat exchanger.
Summary of the invention
Technical problem to be solved by this invention is that a kind of gas fired-boiler cast aluminium heat exchanger will be provided, and it can simplify assembly structure, dwindles heat exchanger volume, improves working (machining) efficiency, reduces manufacturing cost.
The present invention solves the technical scheme that its technical problem adopts: it comprises front module, carries on the back module and be clipped in front module and at least one middle module of carrying on the back between module, each inside modules is provided with water channel, between adjacent block, form flue, front module, middle module, the equal die cast of back of the body module, water channel is comprised of total inlet channel, heat exchange water channel and total water outlet, heat exchange water channel in each module is communicated with total inlet channel, total water outlet, total inlet channel of adjacent block is communicated with, and total water outlet of adjacent block is communicated with.Because adopting extrusion process, this cast aluminium heat exchanger replaces sand casting process, effectively improved production efficiency, reduced manufacturing cost simultaneously, and be all built in inside modules by total inlet channel, heat exchange water channel and total water outlet, not only dwindled heat exchanger volume, and simplified assembly structure, and effectively saved installation procedure and the material cost of water channel, further optimized production efficiency and manufacturing cost.
Described total inlet channel straight line is arranged on module bottom, and total water outlet straight line is arranged on module top, the roundabout setting of the upper and lower layering of heat exchange water channel, and each module is provided with the plug of core-drawing hole and sealing core-drawing hole at the two ends of each layer of heat exchange water channel.Because cast aluminium heat exchanger adopts extrusion process processing, the two ends of total inlet channel straight line setting, total water outlet straight line setting, each layer of heat exchange water channel are provided with the moulding of loosing core of water channel that core-drawing hole is all conducive to cast aluminium heat exchanger.
Described plug is provided with the connection water channel that each layer of heat exchange water channel connected successively.
Described heat-exchanging water trace interpolation cover has trouble flow strip, and trouble flow strip sleeve is in heat exchange water channel, and mounting or dismounting are convenient, and is conducive to the die-casting process of module.The both sides of trouble flow strip are respectively equipped with the spoiler that bends towards heat exchange water channel inwall.Trouble flow strip can make the current in heat exchange water channel produce disturbance, forms turbulent flow, improves the mobility of current, thereby improves heat transfer effect.
Described each module is extended spaced heat exchange bar to flue inner side, and the heat exchange bar of relative two modules staggers and arranges and can embed in the interval of heat exchange bar each other.Heat exchange bar contributes to increase the contact area of flue gas and module, improves the heat transfer effect of flue gas and water, and meanwhile, heat exchange bar embeds and faces mutually in the heat exchange bar interval of module, and the size that contributes to dwindle flue, makes the overall structure of cast aluminium heat exchanger compacter.
The bottom of this cast aluminium heat exchanger is provided with plastic supporting seat, and supporting base periphery is provided with the flanging that extends upward parcel cast aluminium heat exchanger bottom.After the flue gas in flue and the water heat exchange in water channel, flue gas cool-down is liquefied as condensed water, supporting base can be accepted part condensed water, and simultaneously the upwardly extending flanging of supporting base can prevent that condensed water on supporting base, from periphery seepage, is conducive to the processing that collects of condensed water.In addition, because aluminium is active metal, chemical reaction easily occurs, supporting base adopts plastic material, effectively avoids supporting base and cast aluminium heat exchanger generation chemical reaction.
Total inlet channel import of described front module and total water outlet outlet are respectively equipped with plastics and take over, and effectively avoid cast aluminium heat exchanger to be directly connected with other metallic conduits, contribute to prevent that cast aluminium heat exchanger is corroded.
