Abstract

The invention relates to a composite of components which consists of a plurality of micro-channel structures or wing tube structures which comprise a central micro-channel or a central wing tube with two wings. Two of the micro-channel structures or wing tube structures are connected by means of a fin structure. The fin structure extends across the width of the micro-channel structure or the wing tube structure, and has a trapezoidal design. Also disclosed are a condenser and an evaporator having a particularly compact design.

Abstract

The invention relates to a circular heat exchanger having the following characteristics: a first and a second pipe line having blades extending radially from the first and the second pipe line, whereas a coolant can be guided through the first and second pipe line, and the first pipe line forms a first planar spiral and the second pipe line forms a second planar spiral. ln a radial inner area or a radial outer area of the spirals, the first and the second pipe line of the first and the second planar spiral are in fluid connection with one another, and a common coolant can flow therethrough.

Abstract

The invention relates to a heat exchanger for cooling systems, air conditioning systems, or the like, which is equipped with a deicing function. For deicing, the pipes of the heat exchanger are heated and defrosted by an electrical current flow. The drainage of the condensed water is supported by openings in the vanes of the vane pipes used.

• F16L 53/00 - Heating of pipes or pipe systemsCooling of pipes or pipe systems

Abstract

The invention relates to a heat exchanger (1) for dissipating heat from a medium by means of at least one vane tube (20) having a serpentine shape which is disposed in a housing and the straight vane sections (30) of which are disposed in such a way that the vanes (24) of the vane sections (30) enclose an angle in the region of 10°≤ α ≤ 30° with a flow direction (S).
