Definitions

  • the invention relates to a modular heat exchange system with a heat exchange module 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 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.
  • Heat transfer performance can be adjusted. That goes for one
  • the known heat transfer systems are usually self-contained devices whose heat transfer performance can be regulated at best within certain narrow limits by, for example, the
  • Flow rate of a refrigerant is regulated by the heat exchanger, or the amount of the cooling medium, eg of cooling air through the regulation the suction power of a fan is varied. It is also possible, for example, to reduce the amount of cooling air in that the heat exchanger has adjustable Heilabschottklappen, thereby the flow rate of cooling air, which is supplied to the heat exchanger, is adjustable.
  • Heat exchangers are added. Additional heat exchangers can not be simply mounted in or on the existing housing constructions and can be connected into the existing cooling circuits.
  • Heat exchange modules already for purely geometric reasons can not be made sufficiently compact.
  • the object of the invention is therefore to provide an improved heat exchange system which overcomes the problems known from the prior art and with which, in particular, high cooling capacities in a minimal space, ie higher power densities in heat transfer, can be achieved by a compact design.
  • the heat transfer performance is very flexible in a technically simple and economically efficient manner easily changeable, that is both in very wide limits both can be increased, as well as reducible.
  • the invention thus relates to a modular heat exchange system with a heat exchange module comprising at least a first heat exchange module with a heat exchanger.
  • an outer boundary of the heat exchange module is formed by an inflow and an outflow surface such that for exchanging heat between a Transportfluidum and a heat exchanger flowing through the heat exchanger in the operating state, the Transportfluidum supplied via the inflow to the heat exchange module, can be brought into flowing contact with the heat exchanger and can be discharged again via the outflow surface from the heat exchange module.
  • Essential to the invention is thus that in a modular heat exchange system of the present invention, a first boundary surface of a first heat exchange module with respect to a second boundary surface of the first heat exchange module is inclined at a predetermined inclination angle.
  • the invention thus provides a modular heat exchange system which, depending on the design, can be extended substantially periodically or not periodically in one, two or three spatial dimensions by stringing together preferably identical heat exchange modules , or even reducible, by simply removing one or more heat exchange modules from an existing system.
  • the appropriate choice of the angle of inclination, or the concrete choice of the mutually inclined surfaces determines decisively whether a periodic expansion in one, two or three dimensions is possible, or determines the maximum number of heat exchange modules, which are modular according to the invention Have the heat exchange system assembled.
  • the shape of the heat exchange module the external shape of a triangular prism selected with an angle of 60 °, so a maximum of six heat exchange modules of this kind can be combined into a highly compact heat exchange system of hexagonal structure, which have a very high power density in terms of heat transfer.
  • a hexagonal heat exchange system consisting of six heat exchange modules, heat exchange performance due to new requirements can be reduced, so that the necessary number of heat exchange modules can be easily removed from the hexagonal heat exchange system.
  • the heat exchange modules are formed, for example, in the form of a parallelepiped having an inclination angle of 45 °, two such heat exchange modules can each be provided in a particularly compact manner, e.g. be assembled over the inclined surfaces and also, if necessary, be expanded by stringing together.
  • the heat transfer performance and / or heat transfer performance of a modular heat transfer system of the present invention can be easily and efficiently adjusted by regularly repeating preferably identical heat exchange modules or by removing identical heat exchange modules.
  • the first boundary surface of the first heat exchange module is inclined with respect to the second boundary surface of the first heat exchange module at the predeterminable angle of inclination, that the modular
  • Heat exchange system can be expanded by a second heat exchange module, in particular in a compact design, wherein the second heat exchange module is preferably identical to the first heat exchange module.

  • the heat exchanger itself has a load-bearing Function in the formation of the heat exchange module.
  • This can for example be realized in that the heat exchanger itself forms a housing wall of the heat exchanger module, or that the housing of the heat exchanger module does not have a boundary wall at all boundary surfaces of the housing, so that the heat exchanger itself performs a connecting and stabilizing integral function as a housing component.
