Collector pipe for a heat exchanger device, a heat exchanger device and a method for emptying a heat exchanger device

Abstract

A collection tube for a heat exchanger apparatus includes an outflow opening, an inflow opening, a plurality of deflection openings, and a separation element. The separation element is configured and arranged in the collection tube to divide the collection tube into an outflow region in which the outflow opening is arranged, an inflow region in which the inflow opening is arranged, and a first deflection region in which the deflection openings are arranged, the separation element being arranged with respect to a collection tube axis such that the separation element encloses an angle with the collection tube axis, the collection tube axis extending in an axial longitudinal direction of the collection tube.

AI Technical Summary

Benefits of technology

The patent text explains that the efficiency of a heat exchanger is determined by the temperature difference between the fins and the tubes. When the fins and tubes have high conductivity and thickness, and the tubes are close to each other, the heat transfer is more effective and the efficiency is higher. However, this also means that using many tubes increases costs. The technical effect is to improve heat transfer efficiency while balancing cost with the degree of efficiency.

Problems solved by technology

However, many tubes also means higher costs of material and processing so that a higher degree of efficiency is normally associated with higher costs.

For an as high as possible degree of efficiency the tube spacing should be as small as possible which, however, leads to the problem that many tubes are required.

However, many tubes also means higher costs, since the tubes (generally made of copper) are considerably more expensive than the thin fins.

Moreover, a plurality of tubes, in particular having many windings and many arcs in many applications, for example as coolers in power plants, can have the effect that the heat exchanger apparatus cannot be completely emptied during the idle time which is, however, an essential requirement for an application in these fields.
