Beneficial effect of the present invention:
1, in order to solve this great technical barrier, through repetition test, take to install stainless steel heat supply inner tube in cold fluid endothermic tube, stainless steel is hot good conductor, stainless rate of heat transfer > water, greatly increase cold and hot two kinds of fluid thermal in unit volume and exchanged needed heat transfer area, increase heat transfer area, dwindle heating radius, hot fluid passes in the intrafascicular adverse current of cold fluid cylindrical tube, and liberated heat should equal the resulting heat of cold fluid, and cold fluid is annular channel flow, more increase turbulent extent, accelerate rate of heat transfer.Heat transfer area in unit volume is about 2 times of former patent heat exchanger, and the thermal efficiency is high.
The invention solves heating exchange hydrophone hot fluid at certain pressure temperature, in the situation of certain flow rate, turbulent extent does not affect by the low temperature flow state of thermal conductor central cylindrical, stainless steel heat supply inner tube is installed in cold fluid endothermic tube, impel hot-fluid physical efficiency to be absorbed into and be down to minimum temperature, and cold fluid to multipotency is heated to the inlet water temperature degree of hot fluid.The present invention has reached practicality object, the demand that water for bathing temperature long-time continuous output hot water continues to flow.
2, running water endothermic tube of the present invention and heat supply outer tube, heat supply inner tube etc. all adopt stainless steel material, and stainless steel tube corrosion resistance is good durable prolongs life, and well, copper material cost is high for the thinner heat transfer of tube wall, and stainless steel is better than other material.Can exchange again pure hot water clearly from the beginning can have a bath, live practical etc.The smooth fluid flow resistance of stainless steel tube tube wall is little, and incrustation scale is difficult to absorption, extends incrustation scale adsorption time, even if produce micro-incrustation scale, also can acid filling clean, small product size is little, stainless steel tube tube wall is thinner, is convenient to punching, stretching, flange, inlays and pinch limit and weld well, low cost of manufacture.Cool water heating cavity is narrow, and the little side weld method of pinching of cold fluid heating static pressure is water-tight.
3, the change generation by structure brings new technique effect, increases heat transfer area in unit volume, improves heat-transfer area structure heat supply outer tube and can adopt screw thread emboss pipe, bellows etc. more to increase the tt surface area conducting heat.In running water endothermic tube cavity, increase heat supply inner pipe passway and form two partition convection heat transfer' heat-transfer by convection, form the pure adverse current of hot fluid duplicate rows passage and increase MTD, improve heat conduction.Running water is heated in the process of flowing through, and high efficient heat exchanging is without the temperature difference, and long-time continuous output hot water continues to flow.Solved the too low state of prior art cold fluid pass circle R central temperature, cold fluid center can not get absorbing heat or the slow defect of heat conduction.Heat conduction is uneven, the technical barrier that heat loss is large.The low temperature layer of cold fluid tube hub circle of the present invention penetrates cold flow layer through flow of heated fluid through heat conduction and obtains cmpletely heat absorption, accelerates heat conduction speed, has promoted the heat transfer effect of twice.
4, all welded seam joints, take punching, stretching, flange, inlay wall and connect two edge alignment to coincide consistent.Pinch limit from molten downhand welding method welding technology; reduced the thinner welding difficulty of stainless steel tube tube sheet wall; weldering speed is fast, economize welding wire, be shaped, weld seam is attractive in appearance; double-walled contact is pinched side weld penetration power and is formed by force one side welding with back formation welding bead; weld strength is large, 2 times of compression resistances are strong, pinches the water-tight advantage of guaranteeing that heat exchanger security is used of side weld welding seam.
5, heating supply pipe is communicated with all weld seams, welding bead does not soak because pinching side weld welding seam inside and outside wall.The all weld seam welding beads of cold water channel do not soak because pinching side weld welding seam internal face, reduce water logging oxygen corrosion welding bead wall and fluid velocity frictional force friction welding bead wall, effectively increase the anti-ageing intensity of heat exchanger, reduce Product jointing weld seam, fatigue life, without the life-span of leaking long.
6, to solve the housing volume of prior art shell cold fluid pass large in the present invention, storage-type infrastructure cost is high, the defect of weak effect, solved cold fluid cavity large, water storage adds the defect that thermal expansion force great Yi leaks, and output is the shell defect that cold scattering gas can not use as radiator that cools off during hot water.Shell of the present invention be heating pad passage can obtain hot water from the beginning again can be as radiator, inner tube produces incrustation scale energy acid filling and cleans, life of product is long.Having solved internal channel is the defects such as zone of heat liberation fluid resistance is large, affects water circulation heat exchange radiating effect poor etc.
7, for thermal communication straight tube caliber, be less than 1.4～1.7 times of heating tube calibers, running water heat absorption is less than 1.3 times of running water endothermic tubes communicating pipe.Two fluids are flowed through and are located to form turbulence stirring fluidized bed communicating pipe, destroy the effect of viscous flow bottom, form the MTD that hot fluid duplicate rows passage adverse current can be larger, and the cyclic balance heat absorption of going round and beginning again, reduces thermograde efficiency high.
The present invention brings new technique effect by the change generation of structure, takes the reverse-flow convection heat transfer' heat-transfer by convection of heat supply inner and outer pipes duplicate rows passage, has increased heat transfer area, improves heat transfer efficiency, exports for a long time 38 ° of above hot water and successively flows.The invention belongs to renewal product.
