Abstract
The invention relates to the water -heater technical field, in particular to a water-heater liner. The sidewall of the water-heater liner is provided with a flow channel which encloses the liner; the flow channel is provided with an inlet and an outlet for the hot refrigerant to flow through circularly. Due to effective structural design, when the hot refrigerant flows in the flow channel, the distance between water in the water-heater liner and the hot refrigerant is just a sidewall (that is the wall of the flow channel) apart, as if a copper tube is immersed directly in the water of the water-heater liner. In this way, the invention has the efficacies of quick heat-exchange and high hot-efficiency. Furthermore, the flow channel is arranged in the sidewall of the liner, the water-heater liner has the advantages of corrosion-resistance, anti-rusting and long service life.
Description
Technical field:
The present invention relates to technical field of water heaters, refer in particular to a kind of water heater liner.
Background technology:
For the water heater of waste heat recovery, its water storage box has an inner bag, and water stores in inner bag and can carry out heat exchange and heat up.
Waste heat mainly comes from the refrigerant of heat, carries out heat exchange by refrigerant and the water in the inner bag of compressor heat outputting, produces the hot water of the usefulness of living thus.The refrigerant copper pipe of generally flowing through of heat, in the prior art, the water heater that has directly is soaked in copper pipe in the water of inner bag, this structure has the advantage that heat exchange is fast, the thermal efficiency is high, but copper pipe subjects to corrosion and Durchgangshohle, in case Durchgangshohle, water enters copper pipe and follows refrigerant and enters compressor, finally make a mess of compressor, water heater can't be used.
Shown in Fig. 1,2, the water heater that has subsequently be with copper pipe 61 windings on the lateral wall of inner bag 60, utilize copper pipe 61 and inner bag 60 sidewalls to conduct heat, thereby the refrigerant of realizing water and heat in the courage carries out heat exchange, reaches the purpose that adds hot water thus.Though this structure has solved the problem of Copper Tube Corrosion, but, because the double-level-metal wall interval of copper pipe sidewall and inner bag sidewall is arranged between the refrigerant of water and heat, and the bonding gap between copper pipe and the inner bag exists, cause conducting heat slow, the thermal efficiency is not high, make troubles to the user in the use.
Summary of the invention:
The object of the present invention is to provide a kind of structural good, the water heater liner that heat exchange is fast, the thermal efficiency is high.
For achieving the above object, the present invention adopts following technical scheme:
Be configured with runner around inner bag in the interior of inner bag, runner is provided with the refrigerant circular flow warp of importing and exporting heat supply.
Runner is a spiral design, and runner is by two parts compound structure, and the annular groove that a part is arranged with for the sidewall self of inner bag, another part are the covers of sealing covering annular groove, between cover and the inner bag for being welded to connect; Cover has reinforcement.
The section configuration of runner can be circle, ellipse or square.
Be compared with the prior art, the present invention is with the interior of flow passage configuration in inner bag, and is structural good, also has following advantage thus:
When 1, Re refrigerant flows in runner, and have only a sidewall (being flow path wall) to be separated by between the water in the inner bag, just as copper pipe directly is soaked in the water of inner bag, have the effect that heat exchange is fast, the thermal efficiency is high.
2, flow passage configuration is in the interior of inner bag, and promptly the sidewall of runner is the sidewall of inner bag, has corrosion-resistantly, is difficult for getting rusty the advantage of long service life.
3, the shape of runner can be diversified, with the suitable refrigerant of heat and the area of heat transfer between the water of strengthening, reaches heat and imitate height.
Description of drawings:
Accompanying drawing 1,2 is the structural representation of prior art;
Accompanying drawing 3 is structural representation of the present invention;
Accompanying drawing 4a, 4b, 4c, 4d, 4e are runner section structure schematic diagram of the present invention;
Accompanying drawing 5 uses the embodiment schematic diagram for the present invention.
The specific embodiment:
The present invention is further described below in conjunction with accompanying drawing:
See shown in Figure 3ly, water heater liner of the present invention is configured with runner 2 around inner bag in the interior of inner bag 1, and runner 2 is provided with the refrigerant circular flow warp of importing and exporting heat supply.In the present embodiment, runner 2 is a spiral design, hot refrigerant is spiraled flow through the periphery of inner bag 1, prolongs heat exchanger time.
Shown in Fig. 4 a, 4b, 4c, 4d, the 4e, runner 2 is by two parts compound structure, and the annular groove 21 that a part is arranged with for the sidewall self of inner bag, another part are the covers 22 of sealing covering annular groove, between cover 22 and the inner bag 1 for being welded to connect; Cover 22 also can suitably be provided with and have one or more reinforcement 221, and reinforcement 221 increases the structural strength of cover 22, improves compressive property.The section configuration of runner 2 can be circle, ellipse or square, certainly can not limit its shape yet, the madial wall of runner 2, be that the inner bottom part of annular groove 21 can suitably be done the design that some strengthen thermal transfer surface, as planar design or wave design etc., thereby make runner 2 interior hot refrigerants more cover the inner bottom part of annular groove 21, can strengthen thermal transfer surface like this, the efficient that heat is transmitted is higher.
Shown in Figure 5, during use, the inner bag 1 outer skin 3 that also is enclosed with, and between skin 3 and inner bag 1, be equipped with thermal insulation layer 4, improve the insulation effect thus.The import and export of the runner 2 on the inner bag 1 have adapter to draw outwardly, and for use in the compressor of plugging into, the inner bag 1 thereby the realization refrigerant is flowed through reaches heat exchange, and runner 2 spirals and is located on inner bag 1.The refrigerant of heat is exported by compressor, defeated logical and enter runner 2 on the inner bag 1 through pipeline, because runner 2 directly is configured on the sidewall of inner bag 1, the sidewall of inner bag 1 not only carries the refrigerant of heat like this, also constitute heat-exchange surface, be similar to copper pipe of the prior art, directly contact, have the effect that heat exchange is fast, the thermal efficiency is high with water.Because the material characteristic of inner bag 1 itself as stainless steel, can not got rusty, have corrosion-resistantly, the runner 2 of being constructed is durable and not fragile, improves the usability of water heater.
