Embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings, but not as the limit to the present invention
It is fixed.
Referring to shown in Fig. 1 and Fig. 2, embodiments in accordance with the present invention are there is provided a kind of shell and tube exchanger, including with interior
The housing 10 in portion space and the heat exchanger tube 20 in internally positioned space, shell and tube exchanger also include the dividing plate for being arranged on inner space
30, axial direction of the dividing plate 30 along housing 10 is set, and inner space is divided into first chamber 41 and second chamber 42, first
Chamber 41 and second chamber 42 are oppositely arranged and separate (as shown in Fig. 2 first chamber 41 and along the radial direction of housing 10
Left and right directions of two chambers 42 along Fig. 2 is set).
The part of heat exchanger tube 20 is located in first chamber 41, another part is located in second chamber 42, and heat exchanger tube 20 enters
Mouth and outlet are positioned at same one end of the axial direction of housing 10, that is to say, that heat exchanger tube 20 is exchanged heat by two chambers.
It is provided with the first refrigerant import 51 connected with first chamber 41 and the first refrigerant exit 52, housing 10 and is provided with housing 10
The second refrigerant import 61 connected with second chamber 42 and the second refrigerant exit 62.
With reference to Fig. 1, system A refrigerant fluid is entered in first chamber 41 from the first refrigerant import 51, with heat exchanger tube 20
Flowed out after heat exchange by the first refrigerant exit 52；System B refrigerant fluid is entered in second chamber 42 from the second refrigerant import 61,
Flowed out after being exchanged heat with heat exchanger tube 20 by the second refrigerant exit 62.It is the cooling water in refrigeration system with reference to Fig. 3, in heat exchanger tube 20,
Cooling water is tube side fluid, and cooling water is entered in first chamber 41 by heat exchanger tube 20, is changed with system A refrigerant fluid
Heat, axial direction flowing of the cooling water along housing 10 is covered to the tube side of first chamber 41, is turned back in second chamber 42
Row heat exchange, and outflow after the tube side of second chamber 42 is covered, the inlet and outlet of heat exchanger tube 20 is located at the axial direction of housing 10
Same one end, this ensure that the cooling water of tube side fluid can be exchanged heat in first chamber 41 and second chamber 42, it is ensured that
The Length Quantity of tube side, adds heat exchange area, so as to improve the heat exchange efficiency of shell and tube exchanger.
As shown in figure 3, heat exchanger tube 20 is revolution pipeline, the tube side of heat exchanger tube 20 is extended to by the first end of first chamber 41
Second end of first chamber 41, then extend to from the second end of second chamber 42 first end of second chamber 42；First chamber 41
The first end of first end and second chamber 42 be located at same one end of housing 10.
Shell and tube exchanger can be condenser or evaporator.Arranged by the pipeline to refrigeration system, in condenser
Arrangement ensure chilled water Inlet and outlet water it is temperature-resistant in the case of, when cooling inflow temperature be T1, cooling water water outlet
Temperature is T2 (T2>T1), then system A operating mode water temperature is：(T1/2+T2/4), wherein, system A operating mode water temperature is system A's
The average value of coolant-temperature gage is passed in and out, the temperature of system A refrigerants has a fixed difference with system A operating mode water temperature.According to tradition
Axial subregion A systems cooling water condition water temperature be (T1/2+T2/2).Significantly (T1/2+T2/4)<(T1/2+T2/2).
So ensureing the constant situations of heat transfer temperature difference △ Ta, system A condensation temperature (T1/2+T2/4)+△ Ta<(T1/2+T2/2)+
△ Ta just have relatively low condensation temperature.Using the shell and tube exchanger of this radial direction partition type, condensed in steam-refrigerated system
Temperature is lower, and the refrigerating capacity of unit is bigger, and the coefficient of performance of unit is higher so as to improve refrigerating capacity and performance.Coolant system A and B
State when operation for saturation, for the saturation state of refrigerant, pressure value is corresponded with saturation temperature, each system
Operating mode water temperature determine condensation temperature.
Similarly, in the case that the Inlet and outlet water of chilled water is temperature-resistant, when freezing inflow temperature is T3, cooling water goes out water temperature
Spend for T4 (T3 ＜ T4), then system A cold water operating mode water temperature is:(T3/2+3T4/4).According to the system A of traditional axial subregion
Operating mode water temperature be (T3/2+T4/2).Significantly (T3/2+3T4/4) ＞ (T3/2+T4/2).So ensureing heat transfer temperature difference △
Situation constant Tb, system A evaporating temperature (T3/2+3T4/4)+△ Tb ＞ (T3/2+T4/2)+△ Tb just have higher steaming
Send out temperature.Evaporating temperature is higher in steam-refrigerated system, and the refrigerating capacity of unit is bigger, and the coefficient of performance of unit is higher, again
Improve refrigerating capacity and performance, shell and tube exchanger of the invention is by from condenser and vaporizer side double action, it is ensured that
The lifting of the refrigerating capacity and performance of unit.
Preferably, gas averaging board 43 is provided with first chamber 41 and second chamber 42, gas averaging board 43 is located at first chamber
41 tip position, gas averaging board 43 is located at the tip position of second chamber 42.
The calculating of exchange thermal power and the coefficient of heat transfer for convenience, so in the present embodiment, the volume of first chamber 41
It is identical with the volume of second chamber 42.The quantity of heat exchanger tube 20 in first chamber 41 and the heat exchange in second chamber 42
The quantity of pipe 20 is identical.So tube side and heat exchange volume can be calculated.
