Description
Technical field
This utility model relates to technical field of refrigeration equipment, is specifically related to a kind of screw fridge.
Background technology
Screw cooling-water machine adopts screw therefore named screw cold water screw cooling-water machine machine because of its compressor adopted, and unit is by the vaporizer coolant that state is gas out；After compressor adiabatic compression, become high-temperature high-pressure state.By the gas coolant after compressing, within the condenser, isobaric cooling condensation, it is changing into liquid refrigerants after condensed, expand into low pressure then through choke valve, become gas-liquid mixture.The wherein liquid refrigerants under low-temp low-pressure, absorbs by the heat of solidifiable substance in vaporizer, again becomes gaseous coolant.Gaseous coolant reenters compressor through pipeline, starts new circulation.Here it is the Four processes of freeze cycle, it also it is the main operational principle of screw cooling-water machine.Concrete as it is shown in figure 1, include frame 1 ', and it is arranged on the connecting line of the compressor 2 ' in frame 1 ', condenser 3 ', expansion valve 4 ', device for drying and filtering 5 ', vaporizer 6 ', electric cabinet 7 ' and each parts.
Industrial water machine is frequently with shell-tube type water-cooled condenser, but condenser heat exchange efficiency common on the market is low, often condensing tube is simply immersed in liquid refrigerant, not only condensation effect is insufficient, also make condenser cost increase, improve manufacture and use, the maintenance cost of whole cooling-water machine.
Utility model content
This utility model solves the technical problem that existing screw chiller condensation effect is not good.
For solving above-mentioned technical problem, a kind of screw fridge that this utility model provides, condenser on described screw fridge includes columned cylinder and is located at the tube sheet of both sides, described cylinder upper end is provided with air inlet pipe, lower end is provided with drain pipe, both sides tube sheet is offered plural groups for installing the pore be arrangeding in parallel of condensing tube, the outer side seal of tube sheet is provided with water inlet pipe and outlet pipe, one cutoff board is installed in described cylinder, being provided with deflection plate between described cutoff board and barrel, described condensing tube wears on said baffles.
Preferably, described outlet pipe is arranged in the middle part of cylinder, and described deflection plate is symmetrically arranged helical baffles centered by drain pipe.
Preferably, described water inlet pipe and outlet pipe are arranged on one end of cylinder or are separately positioned on the two ends, left and right of cylinder.
By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: by arranging cutoff board at cylinder body bottom, the coolant condensed is entered by cutoff board two ends the bottom of cylinder, by symmetrically arranged helical baffles, carry out convoluted flow at cylinder body bottom around condensing tube, finally discharged by the drain pipe at middle part, improve heat exchange efficiency, and the layout of condensing tube bottom can reducing, reduce production cost and improve the Energy Efficiency Ratio of entirety.

Fig. 2 is the condenser axial section structural representation described in this utility model embodiment.
Main Reference Numerals illustrates:
Compressor 2 ' in frame 1 ', condenser 3 ', expansion valve 4 ', device for drying and filtering 5 ', vaporizer 6 ', electric cabinet 7 ', cylinder 1, air inlet pipe 11, drain pipe 12, cutoff board 13, deflection plate 14, tube sheet 2, water inlet pipe 21, outlet pipe 22, condensing tube group 31, condensing tube group 32.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail:
As shown in Figure 2, a kind of screw fridge, condenser on described screw fridge includes columned cylinder 1 and is located at the tube sheet 2 of both sides, described cylinder 1 upper end is provided with air inlet pipe 11, lower end is provided with drain pipe 12, both sides tube sheet 2 is offered plural groups for installing the pore be arrangeding in parallel of condensing tube, described condensing tube is divided into condensing tube group 31 and condensing tube group 32, the outer side seal of tube sheet 2 is provided with water inlet pipe 21 and outlet pipe 22, described water inlet pipe 21 and outlet pipe 22 are arranged on one end of cylinder 1, cooling water is entered in condensing tube group 32 by water inlet pipe 21, turn back in the chamber of cylinder 1 other end, enter in condensing tube group 31, finally discharged by outlet pipe 22；In described cylinder 1, a cutoff board 13 is installed, it is provided with deflection plate 14 between described cutoff board 13 and cylinder 1, described condensing tube group 32 is located on described deflection plate 14, described drain pipe 12 is arranged in the middle part of cylinder 1, described deflection plate 14 is symmetrically arranged helical baffles with drain pipe 12 for midpoint, and described condensing tube group 32 is arranged on the center of described helical baffles.
The present embodiment is in use, the gaseous coolant produced by compressor is entered in cylinder 1 by air inlet pipe 11, after carrying out heat exchange via condensing tube group 31, it is condensed into liquid, by arranging cutoff board 13 bottom cylinder 1, the coolant condensed is entered by the two ends of cutoff board 13 bottom of cylinder 1, by symmetrically arranged helical baffles 14, convoluted flow is carried out around condensing tube group 32 bottom cylinder 1, finally discharged by the drain pipe 12 in the middle part of cylinder 1, improve heat exchange efficiency, and the layout of bottom condensing tube can be reduced, reduce production cost and improve the Energy Efficiency Ratio of entirety.
The present embodiment can also offer the equally distributed pore corresponding with tube sheet on described deflection plate 14, condensing tube group 32 is worn respectively on it.
Above by specific embodiment, this utility model is described in detail, but these have not been constituted restriction of the present utility model.When without departing from this utility model principle, those skilled in the art it may also be made that many deformation and improvement, and these also should be regarded as protection domain of the present utility model.
