The specific embodiment
In order to make things convenient for the description of back, it is inner that we are referred to as the plate heat exchange unit with space, the passage of space, passage or integrally formed plate inside between two plates of mutual seal welding (be plate to), is called for short inner; It is outside that space, passage between plate heat exchange unit and the plate heat exchange unit are referred to as the plate heat exchange unit, is called for short outside.What this inside configuration flowed is cold-producing medium (freon, ammonia, carbon dioxide, water etc.), flows outside be cold (heat) source fluid (fluid media (medium)s such as water, anti-icing fluid, sewage, air, steam, flue gas), cold-producing medium and cold (heat) source fluid are carried out heat exchange by the plate heat exchange unit.
The below describes plate heat exchange unit scheme and heat exchanger scheme respectively.
Plate heat exchange unit scheme:
In order to improve its bearing capacity, augmentation of heat transfer, the right internal refrigeration storage agent runner 17 of plate can be processed into difformity according to characteristic and the operating pressure design of heat transferring medium, be oval runner, circular flow channel, polygon runner, corrugated runner etc. such as the cross section, cold-producing medium at plate to inner flow passage.The inner surface of runner and plate change outer surface can make as required smooth or be threaded, the rib shape such as concavo-convex, with augmentation of heat transfer.This plate shown in Figure 1 is circular to inner cross section of fluid channel, and plate is that bar shaped is corrugated to outer surface.
The heat exchanger scheme:
Heat exchanger of the present invention is take the plate heat exchange unit as elementary cell, the plate heat exchange unit of a plurality of parallel placements is set according to the heat exchange demand, the mode that each plate heat exchange unit internal refrigeration storage agent side adopts parallel connection, series connection or series connection in parallel to combine connects, form required cold-producing medium circulation area and heat exchange area, cold to form (heat) source fluid passage is then placed in plate heat exchange unit outside by keeping at a certain distance away.
Referring to Fig. 7, shown in Figure 8, be illustrated as that plate heat exchange unit horizontal positioned, plate heat exchange unit are single-row, the signal of many rows' heat exchanger.
The structure explanation; This heat exchanger is made of plate heat exchange unit 10, housing (comprising end cap 13, side plate 3, top board 6, base plate 9), cold (heat) source fluid entrance sleeve 7, cold (heat) source fluid discharge connection 8, baffle plate 11, plate heat exchange unit fixed frame 4.Each plate heat exchange unit is placed with certain spacing, and plate heat exchange unit refrigerant liquid interface tube 2 is connected with refrigerant liquid main 1 respectively, and refrigerant gas interface 5 is connected with refrigerant gas main 14 respectively.Top board 6, base plate 9 are fixed, are sealed by bolt or welding manner with side plate 3, and end cap 13 is by flange 12 and respectively top board 6, base plate 9, side plate 3 fixing, sealings.
This heat exchanger both can be used as evaporimeter, also can be used as condenser (perhaps heat regenerator).Heat transferring medium flows to and is described as follows during work:
Heat exchanging fluid flows to explanation when doing the evaporimeter use: shown in Fig. 7,8, it is inner that cold-producing medium enters respectively each plate heat exchange unit from the refrigerant liquid interface tube 2 of refrigerant liquid main 1 by the plate heat exchange unit, in the internal flow of plate heat exchange unit, carry out heat exchange by plate and external heat source fluid, absorb the heat of heat source fluid, the complete cold-producing medium of heat exchange becomes gas, then from the refrigerant gas interface 5 of plate heat exchange unit out, enter the refrigeration unit suction line by refrigerant gas main 14.Heat source fluid then enters plate heat exchange unit space outerpace from cold (heat) source fluid entrance sleeve 7, and direction flows as shown between the plate heat exchange unit, and each plate heat exchange unit of flowing through is successively discharged from cold (heat) source fluid discharge connection 8 after the cooling.As required, heat source fluid flow to also can with figure in opposite.
Heat exchanging fluid flows to explanation when making condenser (perhaps heat regenerator) and using: referring to Fig. 9, Figure 10, the flow direction of refrigerant flow direction when making evaporimeter is opposite when making condenser (perhaps heat regenerator) and using, and cold (heat) source fluid flows to constant.That is: to enter respectively each plate heat exchange unit from the refrigerant gas interface 5 of refrigerant gas main 14 by the plate heat exchange unit inner for high-temperature high-pressure refrigerant gas, in the plate heat exchange unit, flow, carry out heat exchange by plate and external source fluid, with thermal release to the low-temperature receiver fluid, the complete rear condensation of refrigerant of heat exchange becomes liquid, and then the refrigerant liquid interface tube 2 from the plate heat exchange unit out enters the refrigeration unit liquid feeding pipeline through refrigerant liquid main 1.The low-temperature receiver fluid then enters plate heat exchange unit space outerpace from cold (heat) source fluid entrance sleeve 7, and direction flows as shown between the plate heat exchange unit, and each plate heat exchange unit of flowing through is successively discharged from cold (heat) source fluid discharge connection 8 after heat absorption heats up.Equally, the low-temperature receiver direction of flow also can with figure in opposite.
What Fig. 7-Figure 10 was represented is cold-producing medium single system, single process structural representation, is the most basic version of heat exchanger.
According to heat exchange amount and heat transfer temperature difference needs, the heat exchanger cold-producing medium can be made multisystem, multipaths form.
Figure 11-Figure 12 shows that single refrigeration system, refrigeration system multipaths form.
Figure 13-Figure 14 shows that many refrigeration systems, refrigeration system single process form.
Structure heat exchanger noted earlier is single-row plate heat exchange unit version, a plurality of single-row plate heat exchange units can be made up by the mode that series, parallel or series, parallel combine, and makes the larger heat exchanger of heat exchange amount.Cold (heat) source fluid flows through respectively each external channel successively, flows through successively respectively each external channel after perhaps being divided into multi-channel parallel.
Equally, the heat exchanger that is used in combination both can be used as evaporimeter, also can be used as condenser (perhaps heat regenerator).
The housing of the detachable heat exchanger of the present invention also can be made cylindrical shape except being the cuboid noted earlier, such as Figure 15-shown in Figure 16, to bear more high pressure.Arranging of plate heat exchange unit determined according to factors such as runner layout, refrigeration system feeder numbers.
Adopt the heat exchanger of this plate heat exchange unit also special housing can be set.The plate heat exchange unit according to a certain direction, spacing is placed in the runner of cold (heat) source fluid, is used for remaining (giving up) recuperation of heat or cooling.As being used for chimney waste heat recovery etc.
Figure 11-shown in Figure 16 refrigerant side flows to the flow direction of cold-producing medium when making evaporimeter and use, when making condenser and using refrigerant flow direction in contrast, no longer separately explanation.
