Definitions
- the invention relates to a plate heat exchanger which a stack of equally large and uniformly profiled Plates exists in which neighboring plates alternate facing their front or back, and in that the plates where they touch and support each other, welded or soldered.
- a plate heat exchanger is known from FR-A-2 323 119.
- Heat exchanger Areas of application of this heat exchanger are primarily those Cooling and freezing technology with evaporating and condensing Media, machine cooling and heat transfer processes, where a medium is free from a container in the Heat exchanger enters.
- the principle of the largest possible heat exchanger surface applies to heat exchangers to accommodate in the smallest possible construction volume and large heat transfer capacities if possible to achieve low pressure drops.
- the media are forced to use the entire length of the channels to go through. There is no even heat transfer to achieve a high efficiency of heat transfer, because with the emerging flow a laminar one Boundary layer on the walls, which is the heat transfer with special needs.
- the profiling usually consists of a wavy one Embossing with wave crests of equal size in cross-section and troughs transverse to the direction of propagation.
- the oil filter is axially through a screw connection with the heat exchanger and this as well connected to the motor, as in DE-OS 3440064, the DE-OS 3938254, DE-OS 4039776 and DE-OS 4128153 are shown and described.
- This has the disadvantage that the design and the size of the filter are predetermined by the cooler and that the vibrations occurring on the engine via the heat exchanger are transferred to the filter, which in this type the connection swings on a relatively long lever arm. As a result, the heat exchanger is subject to high dynamic loads exposed.
- the object of the invention is a compact plate heat exchanger to create with a low power to weight ratio unite under the influence of heat-expanding medium offers growing flow cross-section and a cooling Medium with decreasing volume a decreasing flow cross-section, and thereby stabilizing the flow and favors heat transfer.
- this plate heat exchanger the conditions for connecting a filter improve.
- the plates are profiled so that adjacent plates either with its inner and outer flat edge or with touch and support their profiles and between themselves include a gap.
- the cross section the waves are arbitrary. It can be sinusoidal or trapezoidal be.
- Each spiral begins and ends in one up to the height of the wave crests embossed plateau, in the middle of each one Breakthrough is formed through the plate.
- the plates in the stack touch are they welded or soldered, that is to the inner and outer flat edges, at the intersecting Wave crests and the plateaus.
- the breakthroughs in the middle of the Plateaus thus become axially arranged channels between the Columns for the heat-absorbing medium.
- the plates are preferably lasered one after the other welded. But you can also provide a solder layer and soldered in the stack with heat.
- a filter e.g. an oil filter can, which encloses the entire circumference of the heat exchanger and therefore has a filter area many times larger as known axially connectable filters. This filter is characterized by lower pressure drops and a larger one Useful life.
- the highest efficiency of heat transfer is with the plate heat exchanger according to the invention achieved with media, which during the heat exchange the transition from the gaseous to the liquid phase or from the liquid to the gaseous Go through phase. Change at these phase transitions the media extremely their volumes.
- the conventional Extreme changes in pressure occurring in heat exchangers are largely with the proposed plate heat exchanger avoided because the expanding medium with the Radius increasing flow cross section and the condensing Medium is a flow cross section that narrows to the same extent is available. That increases efficiency of heat transfer and places lower demands on the Heat exchanger strength.
- the plate heat exchanger consists of a stack of the same size and similarly profiled annular plates 1, in the adjacent plates 1 are turned against each other by 180 ° and either their front 2 or their back 3 turn to.
- each plate 1 includes the heat exchanger surface 6, which in the form of a Wave 7 is profiled, its wave crests like an Archimedean Spiral run and in one up to the height of the wave crests self-marked plateau 8 begin and end in their In the middle, an opening 9 is formed through the plate 1 is.
- the outer diameter of the plate 1 is many times over larger than their inner diameter to have a large heat exchanger area 6 to get.
- adjacent plates 1 are either the touching flat edges 4 and 5 or the touching plateaus 8 and the crossing waves 7 at their points of contact welded by laser.
- the axial channels 10 and 10 formed by the openings 9 11 are with the ring lines 12 and 13 on the end faces of the plate heat exchanger connected.
- the plate heat exchanger is enclosed by a housing 14 in the scope of which a filter 15 is arranged.
- the filter 15 is hot oil from the engine via line 16 fed that through the filter 15 into the plate heat exchanger flows and after cooling via line 17 again Motor is fed.
- the oil is cooled by water is supplied and discharged via the ring lines 12 and 13.
