FIELD: machine building.
SUBSTANCE: invention relates to a cooling and retaining body for heating elements (10), in particular PTC heating elements, having heating-element holder (11), in which heating elements (10) are mounted. Heating-element holder (11) has a plurality of circumferentially distributed accommodating regions (15), in each of which at least one heating element (10) is arranged, wherein accommodating regions (15) are formed between outer part (13) and inner part (14), which is arranged in outer part (13), and at least outer part (13) has polygonal profile with number of corners (19a) connected by sides (19b), wherein accommodating regions (15) are arranged in corners (19a) of the polygonal profile, and sides (19b) of the polygonal profile are deformed elastically in order to generate a clamping force which acts on respective heating elements (10).
EFFECT: invention enables good heat transfer and secure fixing.
