Abstract
The utility model relates to a water heater composite metal pipe, comprising an internal metal pipe and an external metal pipe. The utility model is characterized in that: a water channel is arranged between the internal pipe and the external pipe, and the water channel and an internal channel of the internal pipe is mutually independent. The water channel comprises a plurality of forms, of which the spiral one is the best, and the straight one is acceptable. The technical proposal is used in the dual-purpose water heater, of which the water channel system of warm water supply and hot water supply are mutually independent, therefore the heat and the hot water can be supplied simultaneously; the utility model has the advantages that the quality of hot water supplied is good, the hot water is quickly supplied, the volume of the metal pipe is small, with few consumables and easy fabrication. The size of the composite pipe produced can be decided by water heater factories according to the output rate of hot water of products.
Description
Technical field
The utility model belongs to the heat-exchanging part technical field on a kind of water heater, is specifically related to the heat supply feed pipe water heater composite metal pipe on a kind of dual-purpose type water heater.
Technical background
In GB6932-2001 " domestic gas instantaneous water heater " national standard of implementing on April 1st, 2002, structure, performance requirement and the test method of dual-purpose type water heater have been made regulation.The existing dual-purpose type water heater of selling on the market, mainly contain two kinds of forms: 1, heating pad pipe (90 ℃ of high-temperature-hot-waters) is directly heated by combustion gas, and hot-water line is arranged in heating pad pipe and high-temperature-hot-water to carry out heat exchange again and provides and bathe hot water (about 40 ℃).Its advantage is independent mutually for two cover water circuit systems of heating and heat supply water, can heat simultaneously and heat supply water, and the hot water quality who provides is good.But the temperature difference of hot-water heating system and heating system is little, and the time of heat exchange is longer, must lengthening heat exchange path, make that volume increases, material increases, and it is slower to go out the speed of hot water, all can waste many water when using at every turn.2, the shared cover heat exchanger of heating and heat supply water, control the flow direction in water route with reversal valve, heating and heat supply water can not carry out simultaneously, its advantage need not the secondary heat exchange, go out that hot water is fast, volume is less, consumptive material economizes, but maximum shortcoming is the high temperature circulation water in the heating pad pipe and the water of hot-water line can not isolate, the hot water water quality inferiority that provides, now existing report is in the water of high temperature (90 ℃) circulation for a long time, because of water evaporates, residual heavy metal concentration is higher, contacts people's skin for a long time, may cause cutaneous lesions.
The utility model is at the heat-exchanging part above shortcomings in the existing dual-purpose type water heater, purpose is to provide the pipeline of a kind of heating and heat supply water separate, can heat simultaneously and heat supply water, hot water water quality is good, need not the secondary heat exchange, volume is little, the water heater composite metal pipe that consumptive material is economized.
Summary of the invention
The technical solution of the utility model is as follows: a kind of water heater composite metal pipe, form by inside and outside double layer of metal pipe, and between pipe and outer tube water stream channel is arranged in being characterized in, be one group of water stream channel, be another group water stream channel in the interior pipe, two groups of passages are separate.
The form of described water stream channel has multiple, best is helical form, and it is shaft-like to be processed into taenidium by interior pipe, its external diameter and outer tube diameter tight fit and get, also can be processed into spiral channel, its internal diameter and interior external diameter of pipe tight fit and get by outer tube wall with certain depth.
In addition, water stream channel also can be straight channel, can process the straight trough road by outer wall of inner tube, and its external diameter and outer tube diameter tight fit and get also can process the straight trough road by outer tube wall, its internal diameter and interior external diameter of pipe tight fit and get.
The technical program is used for the dual-purpose type water heater, can makes heating and heat supply water two cover water circuit systems independent mutually, reach the GB6932-2001 standard-required, heating and heat supply water simultaneously, the hot water quality who provides goes out well that hot water is fast, volume is less, consumptive material province.This composite metal pipe is made simple, and water heater producer can determine that the size of multiple tube produces voluntarily according to the hot water productive rate of product, for the dual-purpose type water heater provides a kind of desirable heat exchange material.
Description of drawings
Fig. 1 is a water heater composite metal pipe structure chart;
Fig. 2 is the cutaway view of Fig. 1;
Fig. 3 is that the water stream channel of water heater composite metal pipe is the inner tube face view of straight channel state.
Fig. 4 is that the water stream channel of water heater composite metal pipe is the outer tube end view of straight channel state;
The specific embodiment
Present embodiment is that spiral helicine structure is an example with water stream channel, referring to Fig. 1 or Fig. 2, form by the double layer of metal pipe, it is shaft-like that its interior pipe 1 adopts extrusion process to be processed into taenidium, push again after during making interior pipe 1 being inserted in outer tube 2, the outer wall of pipe 1 and the inwall of outer tube 2 are combined closely in making, form double-layer composite pipe, phase curl water stream channel 3 between interior pipe 1 and outer tube 2 thus, the internal channel 4 of it and interior pipe 1 is separate, the pitch r of pipe 1 and the tooth depth h of screw thread can obtain desirable inside and outside water route heat distribution in adjusting.Outside along hand of spiral flowing water flow and the heating of combustion gas exchange heat energy generation high temperature, the water route in the interior pipe provides hot water through double layer of metal and combustion gas exchange heat energy.
Certainly, water stream channel 3 also can be straight channel, and concrete enforcement is that outer wall of inner tube is processed straight trough road 5, and its external diameter and outer tube diameter tight fit are referring to Fig. 3; Perhaps outer tube wall is processed straight trough road 6, its internal diameter and interior external diameter of pipe tight fit are referring to Fig. 4.
Although the water stream channel 3 of Xian Shiing has only one in the present embodiment, a plurality of as if water stream channel is made, form one group, do not influence the essence of this patent protection yet.
This composite metal pipe still can adopt conventional spiral fashion so mounting means on water heater, directly heated by stone or metal plate for standing a stove on as a precaution against fire flame.
