Having gap between inner shell and shell, described spacer ring is arranged around inner shell, makes between shell, inner shell and lower perforated plate
Form the 4th cavity；Coolant inlet communication the 4th cavity, is provided with connection the 3rd cavity and the 4th cavity on the housing of inner shell
Coolant through hole, coolant through hole is arranged in the housing of inner shell relative to the region between lower perforated plate and upper perforated plate；Refrigerant exit connects
3rd cavity, Heating medium connects the first cavity, heating agent outlet the second cavity.
In use, coolant enters into the 4th cavity by coolant import to this utility model, then by the housing of inner shell
On coolant through hole enter in the cavity of inner shell, carry out energy exchange with the heating agent in heat exchanger tube, owing to whole inner shell is arranged
In the enclosure, the housing of inner shell is inside and outside all by the pressure of coolant so that the external and internal pressure difference of the housing of inner shell is less, can have
Effect ground reduces the thickness of the housing of inner shell, when inner shell uses alloy steel or stainless steel Steel material to make, in can being effectively reduced
The manufacturing expense of shell, thus reduces the manufacturing cost of whole heat exchanger.
This utility model rod baffle substitutes deflection plate, reduces shell side resistance, is more beneficial for the housing of reduction inner shell
Thickness.
In this utility model, the split-type structural that heat exchange tube design Cheng Youfen heat exchanger tube is formed, same heat exchanger tube
Dividing heat exchanger tube to be coupled together by gas distributor, each point of heat exchanger tube can use different materials according to residing different region
Make, to reduce the integral manufacturing expense of heat exchanger as much as possible.
Further, described coolant through hole is disposed relative to upper perforated plate, closer on the housing of the inner shell of lower perforated plate, can make
Coolant contacts with heat exchanger tube fully, carries out energy exchange with the heating agent in heat exchanger tube.
Further, being provided only with a gas distributor in inner shell cavity, this gas distributor is provided with one and closes cavity, described
Some heat exchanger tubes, by upper point heat exchanger tube and two pieces points of heat exchanger tubes compositions of lower point of heat exchange, above divide heat exchanger tube to lead to lower point of heat exchanger tube
Cross the connection of closing cavity.One gas distributor is only set, the complexity of heat exchanger can be effectively reduced；It it is two sections by heat exchange tube design
Formula structure, to reduce making and the installation of heat exchanger further.
Further, the upper end that heat exchanger tube is arranged in inner shell cavity, a lower point heat exchanger tube is above divided to be arranged in inner shell cavity
Lower end, above divides heat exchanger tube to use alloy pipe to make, and lower point of heat exchanger tube uses carbon steel pipe to make.A upper point heat exchanger tube is arranged in heat exchange
The high-temperature region of device, uses resistant to elevated temperatures alloy pipe to make, and lower point of heat exchanger tube is arranged in the low-temperature space of heat exchanger, uses common
Carbon steel pipe makes, and on the premise of ensureing heat exchanger effective efficiency, reduces the manufacturing cost of heat exchanger.
Further, the housing of inner shell is divided into the upper shell and lower house being tightly connected, and upper shell is positioned at the upper end of lower house,
Described upper shell uses alloy steel material to make, and lower house uses carbon steel material to make.The housing of inner shell is also classified into upper and lower two
Segmentation structure, wherein upper shell is in high-temperature region, have employed steel alloy and makes, and lower house is in low-temperature space, uses carbon steel system
Make, to be effectively reduced the manufacturing expense of heat exchanger.
Further, described some heat exchanger tubes use corrugated tube to make.Described point of heat exchanger tube uses corrugated tube to make, and divides and changes
The top and bottom of heat pipe are provided with construction section.Heat exchanger tube and point heat exchanger tube use corrugated tube to make, and have the advantage that
1, the thermal efficiency is high.Owing to heat exchanger tube uses corrugated form, pipe inner runner section continuously suddenlys change, and causes fluid
Even if being in high turbulence state in the case of flow velocity is the lowest the most all the time, it is difficult to form laminar flow, make the main heat of convection heat transfer' heat-transfer by convection
Resistance is effectively overcome, and the inside and outside heat transfer of pipe is strengthened simultaneously, thus heat transfer coefficient is the highest, can reach 2-3 times of straight pipe type.
2, it is difficult to generate dirt.Due to the high turbulence of fluid in runner, the microgranule in fluid is made to be difficult to deposit fouling, i.e.
A small amount of dirt has been made to generate, the strain produced owing to there is shell journey thermal (temperature difference) stress on corrugated tube, make that there is elastic characteristic
Corrugated tube curvature generation micro-variations, so that corrugated tube heat exchanger has nature antiscale and the ability of natural scale removal.Medium exists
Tube wall is washed away strongly by the inside and outside great turbulence level of pipe, and additionally the smooth arc of bellows surface also can suppress generation and the life of incrustation scale
Long.
3, leakage prevention is strong.Because each ripple of every heat exchanger tube all has the function that self-compensation situation expands with heat and contract with cold, because of
What this need not expansion joint etc arranges the thermal (temperature difference) stress reducing shell journey, has stronger adaptation thermal expansion ability, thus subtracts
Lack the possibility of the leakage losses such as the equipment caused because expanding with heat and contract with cold snaps.
Further, described rod baffle includes that horizontal rod baffle and longitudinal rod baffle, horizontal rod baffle and longitudinal rod baffle are equal
Horizontally disposed, horizontal rod baffle and longitudinal rod baffle are mutually perpendicular to.Mutual horizontal rod baffle and longitudinal rod baffle are set, can protect
The card disturbance to coolant, it is ensured that heat transfer effect.
