Definitions
- the invention relates to a heat exchange system according to the preamble of independent claim 1.
- Heat exchangers are used in refrigerators, e.g. used in ordinary household refrigerators, in air conditioners for buildings or in vehicles of all kinds, especially in automobiles, aircraft and ships, as water or oil coolers in internal combustion engines, as condensers or evaporators in coolant circuits and in a myriad of different applications, all of which are well known to those skilled in the art are.
- the laminated heat exchangers serve, like all types of heat exchangers, to transfer heat between two media, for example, but not only, to transfer from a cooling medium to air or vice versa, as is known, for example, from a classic household refrigerator in which heat is released to the ambient air via the heat exchanger for generating a cooling capacity in the interior of the refrigerator.
- the ambient medium outside the heat exchanger e.g. Water, oil or often simply the ambient air, which absorbs heat or transfers heat to the heat exchanger, for example, is either cooled or heated accordingly.
- the second medium may e.g. be a liquid refrigerant or heat transfer or a vaporizing or condensing refrigerant.
- the surrounding medium e.g. the air
- the coolant that circulates in the heat exchanger system. This is compensated by greatly different heat transfer surfaces for the two media:
- the medium with the high heat transfer coefficient flows in the tube, which on the outside by thin sheets (ribs, fins) has a greatly enlarged surface at which the heat transfer, for. takes place with the air.
- Fig. 3 shows a simple example of an element of such a known laminated heat exchanger. In practice, the
- Heat exchanger thereby formed by a plurality of such elements according to FIG.
- the lamellar spacing is chosen differently for different applications. However, purely thermodynamically, it should be as small as possible, but not so small that the air-side pressure loss is too large. An economic optimum is about 2mm, which is a typical value for condenser and recooler.
- the efficiency is essentially determined by the fact that the heat that is transferred between the fin surface and the air, must be transmitted through heat conduction through the fins to the pipe. This heat transfer is more effective, the higher the conductivity or the thickness of the lamella, but also the smaller the distance between the
- Pipes is. This is called the lamella efficiency. As a lamellar material is therefore nowadays predominantly aluminum used, which has a high thermal conductivity (about 220 W / mK) to economic conditions. The pipe pitch should be as small as possible, but this leads to the problem that you need many pipes. Many pipes mean high costs because the pipes (usually made of copper) are considerably more expensive than the thin aluminum fins. This material cost could be reduced by reducing the pipe diameter and the wall thickness, ie you build a heat exchanger with many small pipes instead of few big pipes. Thermodynamically, this solution would be optimal: very many tubes in close proximity with small diameters. However, a significant cost factor is also the working time for expanding and soldering the pipes. This would increase extremely with such a geometry.
- minichannel or microchannel heat exchangers have been developed, which are manufactured by a completely different process and almost correspond to the ideal of a laminated heat exchanger: many small tubes with small spacings.
- Such profiles can e.g. be made easily and in a variety of forms from a variety of materials in suitable extrusion.
- other methods of making minichannel heat exchangers are known, such as e.g. the assembly of suitably shaped profile sheets or other suitable methods.
- mini-channel heat exchangers In mobile use, mini-channel heat exchangers have established themselves during the 1990s. The low weight, the small block depth and the limited dimensions that are required here are the ideal conditions for this. Car coolers and condensers and evaporators for car air conditioning systems are today almost exclusively realized with mini-channel heat exchangers.
- hybrid coolers or hybrid dry coolers are also known, as disclosed, for example, in WO90 / 15299 or EP 428647 B1 are, in which the gaseous or liquid medium of the primary cooling circuit to be cooled flows through a lamella heat exchanger, and deliver the dissipated heat through the cooling fins partly as sensitive and partly as latent heat to the air flow.
- One or more fans promote the flow of air through the heat exchanger and advantageously have variable speed.
- the dissipation of the latent heat is carried out by a liquid medium, preferably water, which is adapted to its specific values such as conductivity, hardness, content of carbonates and each is applied as a drop-forming liquid film on the air side heat transfer surface.
- a liquid medium preferably water
- the excess water drips back into a collection tray.
- sprayed heat exchanger concepts are known where water is sprayed on the finned heat exchanger and completely evaporated and the evaporation energy is used to improve the heat transfer as well as in the wetting for energy optimization.
- a disadvantage is the restriction of the choice of material of the wetted or sprayed heat exchanger tube in connection with the lamella, where it must not come in conjunction with an electrolyte to corrosion.
- Hybrid heat transfer is thus understood to mean the considerable improvement in the heat transfer of fin heat exchangers with pipes by targeted wetting or spraying of water.
- it is especially necessary to regulate the air velocity in the disk pack in such a way that the water titration on the disk surface does not occur. This is advantageously achieved by a speed control of the fans or by other suitable measures.
- the disadvantage here is that the sprayed or wetting water acts together with dissolved ions as the electrolyte, which can lead to numerous corrosion problems in the usually used material pairings copper pipe, and aluminum fins of the heat exchanger.
- Spray water is subject to high demands in terms of pH, water hardness, chlorine content, conductivity, etc., in order to prevent that on the one hand deposits on thickening on the lamella by evaporation, and on the other hand form too high levels of chemically reactive substances, which in turn can lead to corrosion together with the deposits.
- Another way of obtaining greater heat transfer performance is, in principle, by combining several individual heat exchange components, e.g. through the interconnection of AI-MCHX modules, attempts to achieve greater exchange rates.
- a problem with all previously known heat exchange systems is the pollution of the system components of the heat exchange system, which in principle can not be avoided in the operating state.
- the heat exchangers on which, for example, the cooling air is guided past with the aid of appropriate fan, can be polluted by pollution of all kinds contained in the cooling air with time more and more, which may for example lead to the heat transfer coefficient of the surface of the heat exchanger is lowered, so that the heat transfer performance is reduced.
- This can lead to increased operating costs or in extreme cases, the heat exchange system can no longer provide the required heat exchange performance, which can lead to serious damage in the worst case.
- a connected machine to be cooled such as a data processing system or an internal combustion engine or other machine overheats and is damaged.
- damage to goods such as food that is stored in a cold store, can spoil, for example, in the absence of cooling.
- the heat exchange systems must be cleaned regularly, but this is cumbersome in the known systems, so consuming and expensive.
- it is necessary to open a housing by e.g. To clean the heat exchanger itself or other essential components inside the housing of the heat exchanger.
- the opening of the housing is not only complicated and cumbersome.
- the corresponding connected heat engine must be put out of action, otherwise opening the housing of the heat exchange system alone is not allowed for security reasons, or for technical reasons in the operating state is not possible.
- the cleaning liquid with which the heat exchange system is cleaned for example, water, a detergent-added water or other cleaning fluid must be collected consuming, so that it can be disposed of properly.
- the cleaning liquid soiled after the cleaning process must not simply be supplied to the sewage system. Therefore, in the known heat exchange systems corresponding elaborate devices are provided, for example, separators, separate channel systems, removed via the dirty cleaning liquid and fed to a collection point, or provided other known separation and collection systems that not only take up extra space, but also expensive are under construction and in operation.
- the object of the invention is therefore to provide an improved heat exchange system which overcomes the problems known from the prior art, which in particular is easy to clean, preferably can also be cleaned in the operating state, and with which a dirty cleaning liquid is simply collected or . can be collected and disposed of.
