Problems solved by technology

Due to this helical configuration of the guide vanes, unlike the central area of ​​the housing interior where the helical tube is arranged, a significantly greater laminar flow results, so that there is a risk that the first medium becomes clogged in the area of ​​the helical tube and thus Can't flow out

Embodiment Construction

[0039] Figure 1a Shown is a heat exchanger 10 with an integrated coiled tube 11 as heating coil. In the present case, hot water is provided as the heating medium, and the hot water is conducted through the helical pipe. Alternatively, however, the helical tube can also be formed as a heating coil heated by an electric current (immersion boiler principle). The helical tube 11 can have a smooth surface, but is preferably designed as a corrugated tube. The helical tube 11 is fastened on the heat exchanger housing at each end face by means of a double nipple 13 , 13 ′.

[0040] The shown water connection 12 , 12 ′ is in the form of a collar and a union nut, preferably made of ABS, for supplying and discharging the first medium to be heated. Preferably the first medium and the second medium flow in opposite directions. The heat exchanger 10 has a housing with an oval cross-section. The flow direction of the first medium is indicated by arrow 14 and the flow direction of the se...

Abstract

The invention relates to a heat exchanger (10) having an elongate hollow body with connections (12, 12', 13, 13') for the supply and discharge of a first and of a second medium, in which the first medium is guided through the elongate hollow body in a counterflow with respect to a second medium, and the second medium flows through a spiral tube (11) which extends longitudinally axially between the end sides of the hollow body, and wherein a plurality of deflecting elements (18) projects into the hollow body interior from the hollow body inner casing, which deflecting elements deflect the flow of the first medium. To improve efficiency, it is provided that the deflecting elements project in an alternating sequence from in each case opposite hollow body sides into the hollow body interior and into the region of the spiral tube, in such a way that said deflecting elements end between two spirals, and that the hollow body inner casing has, in sections, a plurality of concavely-shaped constrictions.

Description

technical field [0001] The invention relates to a heat exchanger, in particular for swimming pools, having an elongated hollow body comprising connections for the supply and discharge of a first medium and a second medium, wherein the elongated The hollow body guides the first medium in a counterflow or cocurrent flow relative to the second medium and the second medium flows through a helical tube extending longitudinally between the end faces of the hollow piece, Furthermore, deflecting elements protrude therein from the hollow body facing the hollow part interior, which deflect the flow of the first medium. Background technique [0002] The swimming pool heat exchanger is used to heat pool water as a first medium by means of a heating medium as a second medium. Usually, a heat exchanger is used for this purpose, which essentially consists of a large conduit for the pool water and a heating coil for a heating medium installed therein. As the two media flow through their r...
