Description
Technical field
This utility model relates to a kind of Double-working-condition vaporizer, belongs to vaporizer technology field.
Background technology
Traditional vaporizer, cold flow body walks tube side, a cold fluid inlet, a cold fluid outlet；Coolant walks shell side, a coolant import, a refrigerant exit.When the cold fluid inlet and outlet temperature difference is in evaporator designs temperature range, cold fluid flow amount meets design conditions, and what cold flow body was walked is two-tube-pass.When cold fluid inlet and outlet Temperature Difference Ratio evaporator designs has a narrow range of temperature, when the heat exchange amount of vaporizer is constant, the flow of the cold flow body requiring over vaporizer just increases, after flow doubles, if continuing to walk two-tube-pass, the resistance of vaporizer can be very big, and pump consumption will increase, cold fluid flow amount also is difficult to reach heat transfer requirements, and heat transfer effect can not reach requirement.Traditional vaporizer, the flow of cold flow body, the temperature difference can only be run within the scope of evaporator designs, change along with cold fluid condition, after flow doubles increase, the resistance of vaporizer can be very big, and pump consumption increases, and the heat exchange amount of vaporizer also can be followed and change accordingly, it is likely to not reach designing requirement, regulates inconvenience.
Utility model content
The purpose of this utility model is in that to provide a kind of Double-working-condition vaporizer, in order to improves vaporizer better and controls result of use, conveniently better controls over adjustment vaporizer result of use.
To achieve these goals, the technical solution of the utility model is as follows.
A kind of Double-working-condition vaporizer, vaporizer used includes the first cold fluid inlet, the second cold fluid inlet, cold fluid outlet, coolant import, refrigerant exit, end socket, dividing plate, tube sheet, baffle plate, shell and pipe, and described first cold fluid inlet, the second cold fluid inlet, cold fluid outlet, coolant import and refrigerant exit are arranged on side wall of outer shell；Pipe is arranged on inside evaporator shell；Being provided with tube sheet between pipe both sides, pipe centre position is provided with baffle plate each other；Outer casing end is provided with end socket；Dividing plate it is provided with between end socket and tube sheet.
In this system, cold flow body walks tube side, and coolant walks shell side；The tube side that cold flow body is walked is divided into upper and lower two runners by dividing plate, tube sheet and end socket；When the cold fluid inlet and outlet temperature difference is in evaporator designs temperature range, cold fluid outlet is closed, first cold fluid inlet and the second cold fluid inlet are opened, cold flow body is entered vaporizer by the first cold fluid inlet, flowing in half partial tube on an evaporator under the guide functions of dividing plate, end socket and tube sheet, flow from one end of vaporizer and flow along vaporizer the latter half pipe under the water conservancy diversion of tube sheet plate and end socket again after the other end, cold flow body import flow out vaporizer.Such cold flow body enters vaporizer from an import, vaporizer is flowed out from an outlet, cold flow body is from the left end of the first half of vaporizer along tube side stream to right-hand member, then again from the right-hand member of the latter half of vaporizer along tube side stream to left end, cold flow body has flowed one back and forth in vaporizer, namely cold flow body walks in vaporizer is two-tube-pass.Coolant is entered vaporizer by coolant import, circulates, refrigerant exit flow out under the water conservancy diversion of baffle plate, shell and tube sheet in shell side.Cold flow body and coolant by the mutual heat exchange of tube wall, thus achieve a process of cold flow body and coolant heat exchange in vaporizer in vaporizer.
When cold fluid inlet and outlet Temperature Difference Ratio evaporator designs has a narrow range of temperature, namely after the increase of cold fluid flow amount doubles, now cold fluid outlet is opened, cold flow body is simultaneously entered vaporizer by the first cold fluid inlet and the second cold fluid inlet, under the guide functions of dividing plate, end socket and tube sheet simultaneously on an evaporator in half part and the latter half pipe by vaporizer left end stream to the right-hand member of vaporizer, cold fluid outlet flow out vaporizer.Cold flow body is simultaneously from the upper and lower two-part left end stream of vaporizer to right-hand member under the water conservancy diversion of dividing plate and end socket, namely cold flow body walks in vaporizer is single tube journey.Accordingly even when be when cold fluid flow amount increases, cold flow body resistance in tube side is without increase, and pump consumes without increase.Coolant is entered vaporizer by coolant import, circulates, refrigerant exit flow out under the water conservancy diversion of baffle plate, shell and tube sheet in shell side.Cold flow body and coolant by the mutual heat exchange of tube wall, thus achieve a process of cold flow body and coolant heat exchange in vaporizer in vaporizer.
The mutual switchover operation of said system, it is simply that the operation logic of Double-working-condition vaporizer.The change of the cold fluid flow amount that the change of cold fluid condition brings can be met, even if after flow doubles, the resistance of vaporizer is without increase, and pump consumption is constant, makes the heat exchange amount of vaporizer meet design requirement all the time, easy to adjust reliably.
Above-mentioned Double-working-condition vaporizer, cold flow body walks tube side, two cold fluid inlets, a cold fluid outlet；Coolant walks shell side, a coolant import, a refrigerant exit.When the cold fluid inlet and outlet temperature difference is in evaporator designs temperature range, one import of cold flow body, an outlet, what cold flow body was walked is two-tube-pass.When cold fluid inlet and outlet Temperature Difference Ratio evaporator designs has a narrow range of temperature, when the heat exchange amount of vaporizer is constant, the flow of the cold flow body requiring over vaporizer just increases, two imports of cold flow body, an outlet, what cold flow body was walked is single tube journey, even if flow doubles, now the resistance of vaporizer will not become big, and pump consumption will not increase, and cold fluid flow amount will meet the heat exchange demand of vaporizer.
Having the beneficial effects that of this utility model: the Double-working-condition vaporizer in this utility model, the change of the cold fluid flow amount that the change of cold fluid condition brings can be met, after flow doubles, the resistance of vaporizer does not have too big change, pump consumption will not increase, the heat exchange amount making vaporizer meets design requirement all the time, easy to adjust reliably.
