Definitions
- the invention relates to air-cooled condensers or evaporators, consisting of a fan-evaporator housing in which at least one blower in front of several curved and ribbed ones Coolant pipes is arranged.
- a fan or evaporator To cool an insulated room (cold room or processing room), different conditions are placed on a fan or evaporator: In addition to the temperature, the air humidity (the so-called room climate) and the temperature gradient ⁇ T, the air speed or air circulation and the noise development also play an important role. The external dimensions of the fan or evaporator and its energy consumption are also important.
- Evaporators with a high air throughput are usually offered, the as a heat exchanger block with copper pipes and aluminum fins are manufactured.
- the object of the present invention is the construction of to improve air-cooled condensers or evaporators in such a way that optimal air distribution with minimal space consumption is achieved with low noise.
- air speed and ⁇ T should continue within Limits can be set, even in the high power level still achieved a relatively low energy consumption shall be.
- Coolant pipes semicircular on the outer surface of the circular arc Housing arranged. They lie one above the other at intervals with constant radius with the ribs perpendicular run to the radii and the coolant tubes with larger Slat spacing are interconnected.
- the lamella spacing between 6 and 10 mm
- the Space between the tubes and the vertical ones Ribs or fins should be designed as a diffuser.
- the distance between the fins in the circular plane is designed to increase from a minimum A min on the side facing the center of the circle to a distance maximum A max on the outer housing side.
- the direction of radiation and the volume flow of the air-cooled condenser or evaporator can be made adjustable via the diffuser openings between the fins or ribs of the coolant tubes, the space between the perforated cylinder section and the inner edges of the ripped coolant tubes being designed as storage space.
- Circular segments with segment angles ⁇ of 45 ° are preferred, 60 °, 90 °, 180 ° or 360 ° used. This is an optimal one Use of the cold room possible.
- the placement of the invention Condenser or evaporator can be in a corner, on the wall or in the middle of the room to be cooled.
- the larger slat spacing is due to the avoidance of icing is particularly cheap, with round plate packs with integral fins of up to four rows of pipes in depth can be produced.
- FIG. 1 shows an air-cooled condenser according to the invention or evaporator shown, consisting of a cylinder segment with a semicircular base, as a fan or evaporator housing 1 with cylindrical bowl-shaped and ribbed Coolant pipes 2 is formed.
- the housing 1 is only open on the outer surface 3, so that a radiation from the cylinder segment in the direction of the arrow is possible.
- Up and down is the housing 1 by an upper and lower semi-circular cover 4.5 closed.
- the backside is formed by a flat rear wall 6.
- Figure 2 also shows a trained according to FIG. 1 Condenser or evaporator, but in an exploded view.
- the connection ends 11, 12 are semicircular bent coolant tubes 2 with the radius R to recognize.
- the connection ends 11, 12 are rear plates 9, 10 arranged or screwed.
- the distances A of the coolant tubes 2 are set at 9, 10.
- the pipe bends 13-18 can be seen. Thus it results there is a continuous connection between the individual coolant pipes.
- fans 7 are arranged Blow air into the housing from the outside. The blown air can only through the ribbed coolant tubes 2 through the circular outer surface 3 escape.
- FIG. 3 shows an enlarged detail of the ribbed coolant tubes 2 in the area of a rear plate 9. Furthermore can be seen an upper pipe bend 15, which in the upper area arranged coolant pipes 2a, 2b connects.
- the coolant tubes 2b, 2c, 2d, 2e, 2f have common rib or lamella surfaces. It therefore exists a rib plane E that is perpendicular to that through the radii R formed plane. Is between the ribs a rib space for the passage of the to be cooled or the already cooled air.
- fans 8 can be seen, which are on the lower Cover 5 are attached and the air in the semicircular Blow interior.
- By positive locking with the slat body of the Coolant pipes create a firm connection that also has low gap losses.
- At a distance from the inside edges of the ripped coolant tubes is a perforated one Cylinder section attached, which is an air-permeable Rear wall 6 forms.
- Figures 4 and 5 show alternative embodiments of the liquefier or evaporator according to the invention. It is both Quarter circle segments as well as full circle segments can be displayed, the coolant tubes and the covers accordingly are designed as a quarter circle or a full circle.
- Plates 9, 10 of the cylinder segments are preferably screwed to the rear wall (6, 6a, 6b) and the outer surface 3 for the rear separation of the storage space.
- the spaces between the tubes and the vertically extending fins or fins are designed as diffusers, the distance of the fins in the circular plane from a minimum (A min ) on the side facing the center of the circle to a maximum distance (A max ) rises on the outer side of the housing.

Abstract
Description
neben der Temperatur, der Luftfeuchte (dem sogenannten Raumklima) und dem Temperaturgradienten δT spielen noch die Luftgeschwindigkeit bzw.die Luftzirkulation und die Geräuschentwicklung eine wesentliche Rolle. Weiterhin sind die Außenabmessungen des Lüfters oder Verdampfers und auch sein Energieverbrauch wichtig.
