Definitions

  • the invention relates to a heat exchanger for heating flowable media having the features of the preamble of claim 1.
  • Heat exchangers of this type are well known and are regularly used in the manner of a water heater for heating coating materials in the field of spray technology.
  • the coating material is conveyed by a pump through the flow channel of the heat exchanger, wherein a heating of the coating material takes place by the contact thereof with heat transfer surfaces within the flow channel.
  • electrical heating elements are used regularly, which are arranged in a flow channel at least partially forming body of the heat exchanger.
  • the heating elements or the heating elements must then be arranged in the body so that a uniform heating of the flow channel takes place.
  • the disadvantage here is that the heat transfer from the heating elements to the coating material takes place only indirectly, and first the body formed of metal has to be heated.
  • embodiments of heat exchangers are known in which a heating element is arranged directly in the flow channel.
  • a rapid and effective heating of the coating material is possible here, there is the risk of overheating of the coating material in the case of the comparatively small heat transfer surface of the heating element.
  • the coating material can easily caking or deposit on a Schuelement Diagram, which in turn can lead to a blockage of the flow channel.
  • a comparatively smaller temperature gradient between a flow channel inner surface and the coating material can be achieved, but in this case the formation of a comparatively long flow channel requires formation of a necessarily larger heat exchanger surface.
  • the disadvantage of this results in a complicated ducting or a complex structure of the body, especially since the heat exchanger is often used in conjunction with a mobile sprayer and thus must be relatively compact in its dimensions.
  • a heat exchanger which is essentially formed from a profile body.
  • flow channels are formed, wherein in the flow channels each Heating elements are used.
  • the heating elements heat a liquid medium which flows through flow channel sections of the flow channels and comes there directly in contact with the heating elements.
  • the WO 2005/078355 A1 describes a heat exchanger with a profile body, formed in the profile body flow channels, and heating elements inserted therein according to the preamble of claim 1.
  • the heating elements are in particular surrounded by a spiral-shaped element for guiding the flow.
  • the present invention is therefore based on the object to propose a heat exchanger, which has a simple and compact, easy-to-clean construction and yet allows improved heat transfer.
  • the heat exchanger according to the invention for heating flowable media comprises a profile body with at least one flow passage section of a flow channel of the heat exchanger and a heater arranged in the profile body, wherein the heater has at least two electrical heating elements, wherein a first heating element in a A profiled body formed Walkerelementfact is arranged, and a second heating element is arranged in a sleeve member of the heater, wherein the sleeve member is disposed in the profiled body formed in the flow passage section, such that the heating elements are sealed against the flow channel, wherein the medium to be heated between a flow channel inner surface of Flow passage portion and a sleeve member surface of the sleeve member, which heats from the first and the second heating element can be flowed along, with a physical contact for a heat transfer between the first Heating element and the profile body is made, and wherein a physical contact for a heat transfer between the second heating element and the slee
  • the heating of the profilköpers with a heating element and the use of the likewise heated sleeve member in the flow channel section allows a particularly effective heat transfer to the flowable medium, since the effectively heated heat exchanger surfaces are relatively large.
  • the flow channel section is formed by a profile body which is geometrically uniform and therefore easy to clean.
  • a profile body has no arches or openings, in which possible deposits would be difficult to remove and is also easy to manufacture and available in any length. Due to the effective heating of the flow channel of the heat exchanger can be made relatively short, without a heating element comes into direct contact with the medium. Also, it can hardly come to a local overheating of the medium in the flow channel section due to the thus formed, uniform heat distribution over the heat exchanger surfaces. The associated negative effects are avoided in particular by the fact that the heating elements can not come into contact with the medium.
  • the heat exchanger may comprise a plurality of profile bodies arranged in parallel.
  • a flow rate increased or alternatively a flow channel section can be extended.
  • the heat exchanger can then be designed in particular so that a modular construction of the heat exchanger is possible with a number of profile bodies suitable for the respective application. An adaptation of the heat exchanger to special customer requirements or Requirements are thus easily possible without major manufacturing effort.
  • the heat exchanger may further comprise a cover element and a bottom element, which are each arranged at profile ends of the profile body.
  • a cover element and a bottom element which are each arranged at profile ends of the profile body.
  • connecting channels of the flow channel can be formed in the cover element and / or in the bottom element.
  • the connection channels then do not have to be arranged in one or more profile bodies, but can simply be arranged on the abovementioned elements, depending on the application requirement of the heat exchanger.
  • a plurality of connection channels may be provided on different sides of the cover element and / or the floor element for optional use. The unused connection channels can then be closed, for example with a screw.
  • connection channels can vary depending on the number of profile body used. For the formation of heat exchangers with different heat outputs, therefore, it requires an exchange of cover and / or floor elements with the corresponding number of similar profile body alone.
  • the sleeve member is firmly connected to the lid member.
  • the cover element For one Cleaning the flow channel then only the cover element must be dismantled from the profile body, the cover element is then removed together with the sleeve member from the profile body or from the flow channel section.
  • the sleeve element surface as well as the flow channel inner surface is easily accessible for cleaning.
  • the first heating element which is arranged in the Schuelement technique of the profile body, then also be connected to the cover member in a suitable manner.
  • the heat exchanger can be produced particularly simply if the flow channel section and the heating element receptacle are formed as through-holes in the profile element in the longitudinal direction of the profile element.
  • the sleeve member may form a polygonal cross-section.
  • a heat transfer surface or sleeve member surface can be further increased.
  • an outer diameter of the sleeve element substantially corresponds to an inner diameter of the flow channel section.
  • a flow channel cross-section is then formed solely by the annular cross-sectional space between the flow channel inner surface and sleeve member surface.
  • a multiplicity of subchannels of the flow passage section can also be formed between the sleeve element and the profile body. If the sleeve element surface comes at least partially to the flow channel inner surface to the plant, beyond a ensures a particularly good fit of the sleeve member in the flow channel section.
  • the heat exchanger may have heating elements in a ratio of two second heating elements to a first heating element.
  • connection means may comprise an environmentally sealed housing having means for subdividing the electrical heating elements and control devices.
  • At least one temperature sensor can be arranged in the flow channel.
  • a plurality of temperature sensors may be provided to determine a temperature difference along the flow channel.
  • a temperature control can be carried out on the basis of measured values of the temperature sensor with a PLC control.
  • the flow channel itself may be formed meander-shaped, for example by in series successively arranged flow channel sections, which are connected via connecting channels.
  • a compact design of a heat exchanger can be formed in a particularly simple manner.
