Abstract
The utility model discloses a heat exchange device for a gas appliance, which comprises a cold water inlet, a heat exchange tube and a hot water outlet, and is mainly technically characterized in that the heat exchange tube is profile of which the outer surface is provided with reinforcing fins and the whole heat exchange tube is coiled to form spiral circle bodies; and a gap is arranged between the adjacent circles. The heat exchange device for the gas appliance has the characteristics that the production process is effectively simplified, the production cost is reduced and the like.
Description
Technical field:
The utility model relates to a kind of combustion gas tool heat-exchanger rig, the heat-exchanger rig of particularly a kind of gas heater or burnt gas wall hanging furnace.
Background technology:
Existing combustion gas tool heat-exchanger rig is generally heat exchanger tube, fin and tank shell and is welded, and needs to make a large amount of moulds of industrial equipment, and manufacturing procedure is many, causes complex manufacturing technology, the more high defective of processing cost.In order to overcome these defectives, combustion gas tool heat-exchanger rig is developed.
Summary of the invention:
Technical problem to be solved in the utility model is that a kind of combustion gas tool heat-exchanger rig will be provided, and it can simplify manufacture craft effectively, reduces manufacturing cost.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises cold water inlet, heat exchanger tube, hot water outlet, described heat exchanger tube is that outer surface is provided with the section bar integral disc coiled circle body of strengthening fin, is provided with the slit between the adjacent turn.
Described heat exchanger tube is a cylinder.
Described heat exchanger tube is oval cylinder.
Described heat exchanger tube is a rectangular cylinder.
The inner chamber of described heat exchanger tube is oval hollow pipe.
The slit that is provided with between the described adjacent turn evenly distributes.
Described section bar is an aluminium alloy extrusions.
The utility model is compared the beneficial effect that is produced with background technology:
1, is provided with the section bar integral disc coiled circle body of strengthening fin because the described heat exchanger tube of employing is an outer surface, is provided with the structure in slit between the adjacent turn,, reduce manufacturing cost so it can simplify manufacture craft effectively.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a heat exchanger tube 2 and the profile of strengthening fin 4 among Fig. 1.
Fig. 3 is coiled into cylindrical sectional view for heat exchanger tube 2 among Fig. 1.
Fig. 4 is coiled into the sectional view of oval cylinder for heat exchanger tube 2 among Fig. 1.
Fig. 5 is coiled into the sectional view of rectangular cylinder for heat exchanger tube 2.
Fig. 6 is the flue gas schematic diagram that flow in slit 5 between heat exchanger tube 2 adjacent turns among Fig. 1.
The specific embodiment:
Shown in accompanying drawing 1, present embodiment comprises cold water inlet 1, heat exchanger tube 2, hot water outlet 3, heat exchanger tube 2 is provided with the section bar integral disc coiled circle body of strengthening fin 4 for outer surface, extrusion molding of section bar can adopt aluminium section bar, copper section bar, bar section of stainless steel or alloy profile such as aluminium alloy extrusions.The inner chamber of heat exchanger tube 2 is oval-shaped hollow cavity, as shown in Figure 2.Section bar integral disc coiled circle body constitutes cylinder to obtain best heat exchange effect, as shown in Figure 3, and oval cylinder of all right integral disc coiled or rectangular cylinder, its sectional view such as Fig. 4, shown in Figure 5.Leaving slit 5 and slit 5 between heat exchanger tube 2 adjacent turns in the circle body is evenly distributed between each circle.
Shown in accompanying drawing 6, during work, cold water flows into heat exchanger tube 2 from cold water inlet 1.The one end sealing of heat-exchanger rig, burner inserts from the other end, flow out through the slit between the adjacent turn 5 after high-temperature flue gas that forms during burner combustion and heat exchanger tube 2 heat exchange, last hot water flows out from hot water outlet 3, and equally distributed slit 5 makes heat exchange more even.
Because section bar can be shaped by a coiling of special tooling, omits a large amount of moulds of industrial equipment, shortens manufacturing procedure, thereby simplify manufacture craft, reduce manufacturing cost.And oval pipe is strengthened fin 4 and has been strengthened heat exchange area than the internal heat transfer more excellent performance of round tube, and heat transfer property and the resistance of forming heat-exchanger rig all are better than the typical circular heat-exchanger rig, so the heat exchange better effects if.
