Abstract
The utility model discloses a heat exchanger, comprising a plurality of U-shaped heat transfer sleeves which are all arranged to form bundle shape and fixed through a bracket. Inside a heating pipe the refrigerant moves from a refrigerant room at one end of the U-shaped sleeve to another refrigerant room at the other end of the U-shaped sleeve, while the refrigerating medium moves from a water tank at one end of the U-shaped sleeve to another water tank at the other end of the U-shaped sleeve, making the heat transfer coefficient of the heat exchanger greatly improved. The utility model has the advantages of simple manufacturing processes, lower manufacturing costs, much greater single power than other forms of heat exchanger and capable of being used for all kinds of air-conditioning units, thereby having a great practical value and popularizing value.
Description
Technical field
The utility model relates to a kind of refrigerating plant, relates to the air-conditioning unit specifically and is used to evaporate a kind of heat exchanger with condensation.
Background technology
The heat exchanger of traditional air-conditioning unit adopts shell-tube type usually, board-like, bushing type, shell and tube exchanger, form tube bank by many pipes, tube bank constitutes the heat-transfer area of heat exchanger, the pipe of heat exchanger is fixed on the tube sheet, and tube sheet and shell are linked together, in order to increase the flow velocity of fluid outside pipe, to improve the film coefficient of heat transfer of heat exchanger shell pass, improve the heat transfer situation of heat exchanger, the import and export that have fluid on the housing of many hydraulic barrier heat exchangers and the both sides bobbin carriage have been installed at interval in cylindrical shell, a kind of fluid flows to pipe from a side pipe case in heat exchanger, flows out through the opposite side bobbin carriage, and this paths is called tube side, one other fluid passes in and out heat exchanger shell from the tube connector on the cylindrical shell, and this paths is called shell side.
Case tube heat exchanger is when using as evaporimeter, and tube side flows mostly is cold-producing medium, and what shell side flowed be refrigerating medium, is called dry evaporator, and the flow velocity of dry evaporator cold-producing medium in managing is generally at 180kg/m
2.s ~ 200kg/m
2.s, speed when refrigerating medium flows through tube bundle is 0.5m/s ~ 1.7m/s, it is rational in infrastructure, refrigerant charge is few, comparatively satisfied oil return effect is arranged, but since the structures shape of dry evaporator its thermal compensation relatively poor, refrigerating medium side dirt is difficult to cleaning, be easy to stop up, when particularly evaporating temperature is lower than-5 ℃, freezing accident is very easily taken place in the fresh water refrigerating medium, because traditional screen-wall heat transfer type determined that its heat transfer coefficient is lower, and the copper material consumption is big, tube sheet requires that machining accuracy is higher, complex process, cost of manufacture height.
Plate type heat exchanger is to become corrugated by pressing metal plates, corrugated cardboard sheet is welded, plate is placed between fixed pressure plate and the movable pressure plate by the quantity and the order of design, then with compressing double-screw bolt and nut compresses, guide pillar plays location and guide effect up and down, the plate type heat exchanger compactedness is good, and is in light weight, volume is little, and refrigerant charge is few, and heat transfer coefficient is very high, be approximately 1.8 times of case tube heat exchanger, but the plate type heat exchanger internal volume is very little, can not storage of liquids, therefore need in system, to establish in addition receiver, since the gap between the plate very little (2mm ~ 3mm), thus when containing impurity in the water, stop up easily, when using as evaporimeter, if the water side is stopped up, when evaporating temperature drops to below 0 ℃, can cause between plate and freeze, evaporimeter is scrapped, and because the different plate cold-producing mediums that can cause with gas density of refrigerant liquid distribute inequality, cause refrigerating capacity to reduce, plate type heat exchanger processing technology complexity, price is also higher.
Traditional double-tube heat exchanger structure is comparatively simple, its outer tube is a steel pipe, interior pipe is low rib inner screw thread copper pipe, refrigerating medium is walked shell side, water flow velocity is generally 1.0m/s ~ 1.5m/s, cold-producing medium is walked tube side, and its advantage is that refrigerant charge is few, because refrigerating medium effluent speed is higher, impurity in the water should not precipitate, anticlogging preferably function arranged, and its shortcoming is that interior heat-transfer pipe is heat exchange under unordered state, and the tube refrigerant flow velocity is higher, the problem that the big often appearance of vibrations is revealed, and metal wastage is bigger, heat transfer coefficient is low, and capacity is less, only is applicable to some small-sized refrigerating units.
I have applied for that on October 25th, 2000 name is called " double pipe heat exchanger ", the patent No. is a kind of heat exchanger patent of " ZL00256109.3 ", the helical form that is shaped as that it is characterized in that sleeve pipe and interior pipe thereof, its advantage are that manufacturing process is simple, and refrigerant charge is few, because refrigerating medium effluent speed is higher, impurity in the water should not precipitate, and anticlogging preferably function is arranged, and its shortcoming is that capacity is less, only be useful for some middle-size and small-size air-conditioning units, can not be used for the large-size air conditioning unit.
