Abstract
A hidden and apparent integrated heat exchanger capable of absorbing smoke belongs to the field of gas water heaters and comprises a plurality of detour heat exchange pipes, a water inlet pipe and a hot water outlet pipe which are connected in parallel, wherein the straight pipes of the detour heat exchange pipes are arranged in parallel, the straight heat exchange pipes and a ground line obliquely form (1-60)-degree included angle reference to when the water heater is installed and used, congealed condensed water can flow down and be collected at the lower end along the oblique straight pipes without dripping on a burner below, thus facilitating collection and discharging. The hidden and apparent integrated heat exchanger is safe and reliable, and the thermal efficiency of a gas water heater is greatly improved.
Description
Technical field
The utility model relates to a kind ofly can absorb that flue gas is dived, many pass-over offsets of the gas heater of sensible heat parallel connection heat exchanger, promptly dives, shows integrated heat exchanger.
Background technology
Domestic gas-fired water heater all is to adopt circuitous single tube fin formula heat exchanger at present; This heat exchanger is a fin auxiliary heat switching technology owing to what adopt; Its fault of construction is: when increase pass-over offset length absorbs flue gas heat more, and the condensed water that can condense on fin and the pass-over offset, and condensed water can in disorder dropping onto cause flame-out dangerous on the following burner; Therefore be unfavorable for the collection discharging of flue gas condensing water, the thermal efficiency is low.
Summary of the invention
For overcome existing heat exchanger can not be simultaneously to flue gas is dived, sensible heat absorbs deficiency; The utility model provides a kind of can be combined to one with sensible heat heat exchanger and latent heat heat exchanger, and is beneficial to latent, the apparent integrated heat exchanger of parallelly connected many pass-over offsets that condensed water is collected discharging.
The utility model solves the technical scheme that its technical problem adopted: the pass-over offset heat pipe is by on the water pipe that is connected in parallel more than four or four in the gas heater; Make the water pipe line of whole heat exchanger form the multitube parallel water route; This many pass-over offsets of parallel connection structure does not need the fin auxiliary member, and the straight tube of circuitous heat exchanger tube is arranged in parallel, and is benchmark when installing and using with gas heater; The straight tube of every circuitous heat exchanger tube and horizon form the angle of 1-60 degree, i.e. the state of straight tube for tilting.The condensed water of fume gas condensation on straight tube can flow to every bend drippage of a following end along the circuitous heat exchanger tube straight tube that tilts toward dirty, regathers discharging.
The utility model has the advantages that, needn't increase an independent condensed heat exchanger in addition, reduced cost and material; Latent, being integrated of sensible heat exchanger, the whole smaller volume of gas heater, light; Condensed water can not drop onto on the burner; The thermal efficiency improves more than 20%.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Description of drawings
Fig. 1 is the pipeline structure front schematic view of the utility model embodiment.
1. outlet pipes among the figure, the coil pipe of 2. intaking, 3. circuitous heat exchanger tube, 4. straight tube, 5. bend pipe.
The specific embodiment
The coil pipe (2) of in Fig. 1, intaking is coiling outer wall of combustion chamber; What be connected is the heat exchanger of participating in heat exchange directly between water inlet coil pipe (2) and the outlet pipe (1); Circuitous heat exchanger tube (3) by four parallel connections is formed; One end of every circuitous heat exchanger tube (3) is communicated with an end of water inlet coil pipe (2), and the other end then is communicated with outlet pipe (1).
Claims (1)
1. latent, an apparent integrated heat exchanger is made up of how circuitous heat exchanger tube, water inlet pipe and the outlet pipe of parallel connection, it is characterized in that: be benchmark when installing and using with gas heater, the angle that the straight tube of circuitous heat exchanger tube and horizon form the 1-60 degree tilts.
