Definitions

  • the invention relates to a distributor for a plate heat exchanger according to the preamble of patent claim 1.
  • a distributor for a plate heat exchanger of the type mentioned is from the document DE 20 2008 004 582 U1 known.
  • This distributor consists of a distributor body with an interior through which a fluid flows and with a supply connection for the fluid arranged on one side of the distributor body and hydraulically connected to the interior.
  • this distributor and this also applies to the distributor according to the invention to be explained below, has a plurality of outflow openings for the fluid.
  • Such a distributor is, as described in said document, used in plate heat exchangers to distribute the fluid as evenly as possible on the channels between the plates can.
  • the invention has for its object to improve a distributor of the type mentioned.
  • a more universally applicable distributor is to be created.
  • an additional space for a sensor for detecting the temperature of the fluid in the interior and on the side of the supply port on the distributor body an opening for introduction of the sensor is provided in the additional space.
  • the distributor for a plate heat exchanger thus characterized by the fact that the supply port and the sensor or the temperature sensor are arranged on the same side of the distributor body, which in particular brings with it the advantage that the temperature sensor together with the distributor in the plate heat exchanger can be used and then formed in a simple manner, for example, with a control device electrically connected.
  • the distributor for a plate heat exchanger shown in the figures initially consists in a known manner of a distributor body 1 with a flowed through by a fluid interior 1.1 and with a arranged on one side of the manifold body 1, with the interior 1.1 hydraulically connected supply port 1.2 for the fluid.
  • the distributor body 1 has a round cross section and / or that preferably at least one insertable into the plate heat exchanger part of the distributor body 1 is cylindrical.
  • both the interior 1.1 and the additional space 2 are tubular and are arranged with their main tube axes extending parallel to each other.
  • the interior 1.1 preferably has a round cross-section.
  • the additional space 2 preferably has a round cross section.
  • the interior 1.1 and the additional space 2 are preferably formed hydraulically separated from each other.
  • the distributor body 1 is preferably formed from a base body 1.4 and a flow guide body 1.5 which can be inserted into the base body 1.4. It is also preferred that the distributor body 1, in particular optionally the base body 1.4 and / or the flow guide body 1.5, is formed of a good heat-conducting, in particular metallic, material.
  • the flow guide body 1.5 is preferably formed via a preferably the supply port 1.2 on the manifold body 1 opposite insertion opening 1.6 on the base body 1.4 in this insertable (see FIGS. 3 and 6 ).
  • the supply port 1.2, the interior 1.1 and the insertion opening 1.6 preferably form a passage opening on the distributor body 1 with the flow guide body 1 taken out. It is likewise preferred to provide a concentric annular gap 1.8 between the base body 1.4 and the flow guide body 1.6.
  • the flow guide body 1.5 preferably has an inlet opening 1.5.1, a passage space 1.5.2 and an outlet opening 1.5.3 for the fluid, such as, inter alia FIG. 4 is shown.
  • the supply port 1.2 is formed ausmündend in the inlet opening 1.5.1 of the flow guide 1.5. It is also preferred that the outlet opening 1.5.3 has a larger cross-sectional area than the inlet opening 1.5.1.
  • the distributor body 1 preferably has a plurality of outflow openings 1.7 (see FIG Figures 1 and 2 ), in which case the interior 1.1 is arranged between the outflow openings 1.7 and the additional space 2. It is preferred that the outflow openings are arranged 1.7 on the base body 1.4 on one of the outlet opening 1.5.3 on the flow guide 1.5 opposite side of the concentric annular gap 1.8. Furthermore, the outflow openings are preferably 1.7 along a line next to each other and preferably arranged with this line parallel to the pipe-shaped interior 1.1. Finally, it is further preferred that the outflow openings 1.7 are arranged parallel to the cylinder main axis of the at least partially cylindrical distributor body 1.
  • the distributor according to the invention works as follows: First, the flow guide 1.5 is introduced via the insertion opening 1.6 in the distributor body 1 in such a way that the outlet opening 1.5.3 to that side of the base body 1.4 has, which is opposite to the side on which the outflow openings are arranged 1.7. In order to simplify the exact positioning, guide elements can be attached to the distributor body 1 and to the flow guide body 1.5 for this purpose. After this step, the distributor body 1 is inserted into a fluid connection of a plate heat exchanger and fastened there. Ideally, the outflow openings 1.7 in this case come to rest in a plane with the free spaces between the heat exchanger plates. Now, a temperature sensor is introduced into the additional space 2 and the fluid connection of the plate heat exchanger connected to a corresponding fluid supply, such as a water supply.
  • a corresponding fluid supply such as a water supply.
  • the fluid flows through the fluid port and through the supply port 1.2, and the inlet opening 1.5.1 first in the flow guide 1.5. From there, the fluid exits through the outlet opening 1.5.3 in the annular gap 1.8. It then flows through the annular gap 1.8 and leaves the distributor body 1 through the outflow openings 1.7. Meanwhile, the temperature of the distributor body 1 and thus indirectly the temperature of the fluid is measured by the temperature sensor in the additional space 2. Due to the multiple diversion of the fluid flow within the distributor body 1, turbulences are generated in the same and thus also the temperature distribution in the distributor body 1 stabilized, which benefits the temperature measurement. After the fluid exits through the outflow openings 1.7, this is distributed between the plates of the heat exchanger.
  • the temperature sensor If the temperature sensor is faulty or if replacement is provided for it for other reasons, it can simply be removed from the additional space 2 without having to disassemble the plate heat exchanger, and a new one can be inserted there. This, together with the simple installation of the distributor body 1 in an existing plate heat exchanger, leads to a very flexible distributor.
