Abstract
The invention discloses a heat exchanger with a reducer pipeline. An inner pipe of the heat exchanger comprises a first guiding pipe and a second guiding pipe communicated with the first guiding pipe; further, the inside diameter of the first guiding pipe is less than that of the second guiding pipe; when a cooling medium is high-temperature and high-pressure gas and flows in the first guiding pipe, as the pipe diameter of the first guiding pipe is smaller, the flow velocity is slow; the cooling medium has longer heat exchange time; when the cooling medium flows in the second guiding pipe, as heat is conducted outside mostly, more liquid exists; furthermore, the pipe diameter of the second guiding pipe is larger; and the generated liquid can be quickened to flow away, thereby preventing the major area of the heat exchanger from being in a low-efficiency condensation state. Through the improvement of the structure, under the condition that the heat exchanger has smaller power, the one-time heating also can be achieved; under the condition that the temperature, the pressure and the flow are the same, when the cooling medium enters the heat exchanger, the length of the pipe needed for making the same heat is half of that of a general heat exchanger; and not only is the material cost saved, but also the size of the heat exchanger can be decreased.

The invention has the beneficial effects as follows: inner tube of the present invention comprises the first conduit and the second conduit communicated with the first conduit, and the internal diameter of the first conduit is less than the internal diameter of the second conduit, when refrigerant is that high temperature and high pressure gas is while flowing in the first conduit, cause the first conduit caliber is less, thereby flow velocity is fast, obtain larger thunder and consult the Shi Nuo number, and while in the second conduit, flowing, because heat major part conducts, thereby there is more liquid to exist, and second the conduit caliber larger, the liquid produced can be accelerated to flow away, thereby avoided the most of area of heat exchanger to be in the poor efficiency condensing state, between outer tube of the present invention and middle pipe, be provided with the petal sheet, this petal sheet is provided with flowing hole, thereby has increased the disturbance of water, has strengthened heat transfer effect, the refrigerant arrival end of the first conduit is connected with the refrigerant output of supercharging device, by the pressurization of supercharging device, can make coolant distribution more even.
Improvement by said structure, the present invention also can accomplish once to heat in lower-powered situation, in the situation that temperature, pressure and flow are identical, when refrigerant enters heat exchanger, making the required pipe range of identical heat is 1/2nd of general heat exchanger, not only save material cost, also can reduce size of heat exchanger.
The accompanying drawing explanation
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is profile of the present invention;
Fig. 2 is the A-A cross section view of Fig. 1;
Fig. 3 is overview of the present invention.
The specific embodiment
Referring to figs. 1 through Fig. 3, the invention discloses a kind of heat exchanger with reducer pipeline, comprise heat exchanger tube 9 and be arranged at the refrigerant in heat exchanger tube 9, heat exchanger tube 9 comprises outer tube 1 and is arranged at the inner tube in outer tube 1, this inner tube comprises the first conduit 2 and the second conduit 3 communicated with the first conduit 2, and the internal diameter of the first conduit 2 is less than the internal diameter of the second conduit 3, described refrigerant flows to the second conduit 3 by the first conduit 2.
In this specific embodiment, the junction of described the first conduit 2 and the second conduit 3 is provided with transition conduit 4, and in the time of by transition conduit 4, can reducing reducing, tube wall is to the resistance of the mobile formation of refrigerant and the flow-disturbing therefore produced.Described inner tube is provided with middle pipe 5, and should in pipe 5 inwall and the outer wall close contact of inner tube, refrigerant is mobile in double walled ducting provides protection can be for secondary refrigerant leakage the time.5 of described outer tube 1 and middle pipes are provided with petal sheet 8, and this petal sheet 8 is provided with flowing hole 7, thereby has increased the disturbance of water, has strengthened heat transfer effect.
The refrigerant arrival end of described the first conduit 2 is provided with buffering supercharging device 6, and the refrigerant arrival end of this first conduit 2 is connected with the refrigerant output of buffering supercharging device 6, buffering supercharging device 6 can make coolant distribution more even, and the pressure when increasing refrigerant and entering independent reducing microtubule pipeline heat exchanger, improve the coefficient of heat transfer.
Operation principle of the present invention is as follows: because the casing diameter of independent reducing microtubule pipeline heat exchanger is fine, under same traffic, the flow velocity of refrigerant and water increases, can obtain larger Reynolds number, add that the liquid refrigerants reduced thickness causes detention layer thickness greatly to reduce, therefore the coefficient of heat transfer can improve greatly, makes heat transfer rate faster.At the refrigerant passage end, add Large Diameter Pipeline, help condensate liquid is flowed out as early as possible.Refrigerant is at the heat exchanger condensation heat transfer, is condensed to the saturated or subcooled liquid of pipe inner outlet from the overheated or saturated high temperature and high pressure gas of import always.The existence of condensate liquid has hindered high temperature and high pressure gas and has contacted with the tube wall face, becomes the main thermal resistance of condensation heat transfer.Owing to getting over proximal end, the ratio of condensed fluid is more, and the diameter that strengthens condensation pipe can reduce flow resistance, makes condensed fluid accelerate to flow out.Because fluid has viscosity, so while flowing, produce internal friction, form flow resistance, in the time of according to Fanning equation and newton law of viscosity, can knowing laminar flow by inference, pressure depreciation and refrigerant passage pipe caliber square are inversely proportional to.
When complete turbulent flow, flow resistance only to square being directly proportional of speed. add Large Diameter Pipeline, the flow velocity of condensate liquid slows down, no matter in laminar flow or turbulent flow, flow resistance or the pressure depreciation all can reduce, so slowing down of flow can significantly reduce.This segmentation is widened, augmented flow, the design of lowering pressure drop make when refrigerant be that high temperature and high pressure gas has long heat-exchange time during the dominated stage, when more condensed fluid produces, accelerate to flow away, avoid heat exchanger major part area to be in the poor efficiency condensation process.And be provided with the petal sheet between outer tube and middle pipe, and this petal sheet is provided with flowing hole, and petal sheet and flowing hole can increase the disturbance of water, strengthen heat transfer effect by disturbance.
Heat exchanger after improving by use, even the small-power coolant water heater also can be accomplished once to heat.When refrigerant enters heat exchanger, work as temperature, in the pressure situation identical with flow, making the required pipe range of identical heat is 1/2nd of general heat exchanger.This not only saves material cost, also can reduce size of heat exchanger.
