Abstract
The utility model discloses a heat exchange coil pipe device of an air energy water heater. The heat exchange coil pipe device of the air energy water heater comprises a heat exchange coil pipe arranged inside a water tank, wherein a plurality of spiral coil pipe bodies are arrayed and connected in parallel to form the heat exchange coil pipe. The two ends of the coil pipe are respectively provided with a casing pipe which is connected with an external water pipe, and the outer diameter of each casing pipe is larger than the outer diameter of the coil pipe. A groove which is used for arrangement of a seal ring is formed in the inner surface of each casing pipe. The casing pipes with the outer diameter larger than the outer diameter of the coil pipe are arranged at the two ends of the coil pipe respectively, the grooves which are used for arrangement of the seal rings are formed in the inner surfaces of the casing pipes respectively, and internal thread sections which are arranged on the right sides of the grooves and screwed with the outer pipe are arranged on the inner surfaces of the casing pipes respectively. According to the heat exchange coil pipe device, the problem that water outflows from the joints of the coil pipe and the water pipes after the coil pipe is used for a period of time can be effectively solved.
Description
Technical field
The utility model relates to the air-source water heater device, is specifically related to a kind of heat exchange coil device of air-source water heater.
Background technology
Air-source water heater is the hot water apparatus of new generation of gas heater, electric heater and solar water heater of continuing, be the safety energy-conserving environment protection type water heater of comprehensive electric heater and solar water heater advantage, can round-the-clock running in 365 days in a year manufacture identical hot water amount.Because country does not also have concrete industry standard, so air-source water heater market is very different, after the part air-source water heater is used a period of time, heat exchange coil and outer water tube junction will spilling waters, the water overflowed can be accelerated the corrosion of water pipe and the heat exchange coil of junction, and affects the service life of water pipe and heat exchange coil.
The utility model content
For above-mentioned deficiency of the prior art, the heat exchange coil device solves of the air-source water heater that the utility model provides heat exchange coil and outer water tube junction the problem of spilling water appears.
In order to reach the foregoing invention purpose, the technical solution adopted in the utility model is for providing a kind of heat exchange coil device of air-source water heater, and it comprises the heat exchange coil that is arranged on water tank inside, and described heat exchange coil is arranged in parallel by some spiral coils; The two ends of described coil pipe are provided with the sleeve pipe be connected with outer water tube, and the sleeve pipe external diameter is greater than the coil pipe external diameter; The inner surface of described sleeve pipe offers for the groove of sealing ring is set.
Further, be provided with the internal thread segment screwed with outer water tube on described sleeve pipe.
Further, the inner surface of described coil pipe is provided with screw thread.
Further, the inner surface transition position of described coil pipe and sleeve pipe is provided with one domatic.
Further, the internal thread segment on described sleeve pipe is arranged on the right-hand member of groove.
The beneficial effects of the utility model are: the external diameter that 1, the coil pipe two ends arrange is greater than the sleeve pipe of coil pipe external diameter, and the problem of spilling water appears in junction that the internal thread segment screwed with outer tube arranged for groove that sealing ring is installed and groove right side of offering on the inner surface of sleeve pipe can solve coil pipe and water pipe effectively in use for some time.
The flowing velocity that the screw thread of the inner surface setting of coil pipe can slow down its internal flow improves heat exchanger effectiveness.
The accompanying drawing explanation
Fig. 1 is coil pipe and partial sectional view after outer tube is connected.
Wherein, 1, coil pipe; 2, domatic; 3, sleeve pipe; 4, groove; 5, internal thread segment; 6, water pipe.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:
As shown in Figure 1, the heat exchange coil device of this air-source water heater comprises the heat exchange coil that is arranged on water tank inside, and described heat exchange coil is arranged in parallel by some spiral coils 1; The two ends of described coil pipe 1 are provided with the sleeve pipe 3 be connected with outer water tube 6, and sleeve pipe 3 external diameters are greater than coil pipe 1 external diameter; The inner surface of described sleeve pipe 3 offers the groove 4 for sealing ring is set, and the arranging of groove 4 can solve the problem that spilling water appears in coil pipe 1 and the junction of water pipe 6 in use for some time effectively.
Be provided with the internal thread segment 5 screwed with outer water tube 6 on sleeve pipe 3, further guaranteed the sealing of coil pipe 1 with the junction of water pipe 6; Internal thread segment 5 on preferred described sleeve pipe 3 is arranged on the right-hand member of groove 4.
The inner surface of coil pipe 1 is provided with screw thread, and the flowing velocity that can slow down its internal flow that arranges of screw thread improves heat exchanger effectiveness.
It is one domatic 2 that the inner surface transition position of coil pipe 1 and sleeve pipe 3 is provided with, in order to quickly coil pipe 1 and water pipe 6 are installed together.
Although by reference to the accompanying drawings the specific embodiment of the present utility model is described in detail, should not be construed as the restriction to the protection domain of this patent.In the described scope of claims, the various modifications that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
