The serial heating exchanger patented product of the applicant's invention goes on the market for many years, but serial heating exchanger patented product in use also finds to exist bigger defective and deficiency gradually.
Thermal medium is by housing tube chamber channel cycle in the former patented product, design has thinner heat absorption copper tube in the housing tube chamber passage, is flowing cold running water formation circulation in the copper pipe and is being heated to form hot water, lives required for people, have a bath, do washing, scrub conveniently, improve people's quality of life.Old-fashioned heating system be last confession next time, be installed in series, forced circulation heating because the heating source imbalance is divided into top section and end segment heating pipe network, temperature difference has appearred, formed high-temperature area and low-temperature region.The design difference of pipe network, press Lou Changshe flatly pipe laying or cross-over pipe, meet stairway unit to open branch and be responsible for mouth, a perpendicular upright heating pad pipe is conducted to high level (6 floors building), establish the horizontal branch pipe network by high-rise house type room and form the heating pipe network of connecting with radiator next time by last confession, cause heating effect good (for the high-temperature region) more than 3 layers, owing to the heat radiation heat loss of the above radiator of floor, the heating temperature reduces by 10～15 ℃ below 3 layers.So reach end segment heating weak effect (being low-temperature space) below 3 layers.
At present the heating pipe network of installing adopts the only family circulation heating system of system that is that Every household has an ammeter, establish the buried or cross-over pipe of level by building length, be divided into initial end segment, meet the stairway unit perpendicular two upright back-flowing and branched persons in charge of confession to the building high level, every layer is met the family to open for the back-flowing and branched mouth of pipe, cause 1～3 layer of heating effect good (for the high-temperature region), owing to flow and difference pressuring loss, cause heating effect to differ from 10 ℃～20 ℃ more than 3 layers; So reach end segment heating weak effect (being low-temperature space) more than 3 layers.
The floor heating heating heating of adopting at present also is the only family circulation heating system of system that adopts that Every household has an ammeter, but the heating source temperature is no more than 60 ℃.Because pipe network flow velocity resistance is big, use the heat exchanger patented product heat exchange effect of the applicant's invention in the past undesirable, can't have a bath.Because heat exchanger patented product in the past at be that the heating source temperature is 75 ℃～95 ℃, can't in pipe network is warmed oneself in floor heating, use.
Heat exchanger producer is for the balance heat exchange and hot water can be provided continuously, designed interior heat absorption copper pipe is reduced to Φ 6～8mm by Φ 10mm and (is considered copper material rise in price factor, and the more little heat-transfer effect of the pipe diameter of heating surface is good more, and the long more heat exchange efficiency of flow process is high more), length is between 15～25m.When adopting counter-flow heat exchanger, the heat-sink copper length of tube is also between 12～15m.Because the heat absorption copper pipe is long meticulous, U type curved too many (manufacture craft all is U type or screw type and inserts in the heating installation hot water tube chamber) causes being in the user's of heating high-temperature region the easy fouling of running water endothermic tube and stops up; And can not provide sufficient hot water to have a bath for user at heating low-temperature space and employing floor heating heating system.The domestic consumer buys a heat exchanger for 500～1000 yuan, uses 2～5 heating phases, and the running water endothermic tube easily forms incrustation scale (recirculated water in the heating tube is soft water, can not form incrustation scale after the intensification) in the heating high-temperature region, can't clean maybe and can't dredge; Though be difficult for forming incrustation scale in heating low-temperature space and floor heating heating user running water endothermic tube, the heat production water yield is little, the hot water temperature is low, can not have a bath.Therefore, there is great defective in existing heat exchanger product in the actual life.
The formation thing of incrustation scale comprises suspension in the water, colloid thing, dissolved matter etc.Domestic water is a hard water, and the water hardness (H) is generally 7～10 equivalent parts per millions, and water is heated to more than 70 ℃, and calcium ions and magnesium ions just forms incrustation scale in the water; Incrustation scale is adsorbed on the inner wall of metal tube face, absorption 1mm incrustation scale, and caliber dwindles 2mm, the pit corrosion metal surface, cavity is stopped up in the conduction of influence heat, wastes energy.
With regard to heat dissipation heat exchanger 200320106748.7 patents, there are deficiency or significant deficiency, easy scaling in the heat absorption copper pipe, the heat absorption copper pipe is easily scrapped.
General solution for the fouling of running water endothermic tube: for example test with 200320106748.7 patent heat dissipation heat exchangers, this long 17.48m of copper pipe Φ 8.5mm (flow process of running water) that absorbs heat, surperficial 0.4665412m absorbs heat
2
(1) acid washing test method: this heat absorption copper pipe is long, cavity is meticulous, the bending place is too many again; Import and export on a horizontal end face, no drop and reaction cavity, and cavity is narrow, manually pours into after the acid solution outside spray reactant liquor foam of moment, reactant is blocked very little passage afterwards, and acid solution can't be poured into, therefore can not pickling, the copper pipe that absorbs heat is scrapped.
(2) shell is dissected facture: outer cover of heat exchanger (heating tube) is analysed extracted out the heat absorption copper pipe and straightening is cut into pieces, roasting and gently beat with the oxygen welding fire, its part incrustation scale comes off, and with neutralizing with buck after the pickling, is welded into integral body more piecemeal again.Entire process process expense is too high, and the life-span weakens, and therefore dissects facture and is not accepted.Can only change the heat absorption copper pipe, but the user draws out a very big expense again using 2～5 heating after dates, cause use cost to increase, waste of material, the product life cycle shortens.
