Definitions
- the invention relates to a frost monitor with a supply and exhaust air openings for a convection air flow receiving housing, in particular made of plastic and with an electrical heating element.
- this object is achieved by a tubular heating element with two straight connections having network connections and a spirally wound tubular heating element section with two deflection bends arranged in the area of the end facing away from the network connections and a single deflection bend arranged at a distance from the end facing the network connections, whereby the extend two deflection bends radially offset from each other with different distances to the network connections.
- the two deflection bends are preferred and the straight sections of the tubular heating element are formed in mutually parallel planes, while the individual deflection bend is directed obliquely to the planes of the two deflection bends.
- the straight sections of the tubular heater have thermally inactive zones over first areas adjoining the network connections, and that a thermally active second area formed by sections of the straight sections and the deflection bend is connected to the thermally inactive zones.
- the thermally inactive zones in the area of the mains connections prevent damage, e.g. Corrosion on these and contribute to the uniform heat dissipation over predetermined areas to the interior of the receiving housing.
- the tubular heating element with the straight sections preferably the end regions having the network connections
- the fixation can be done arbitrarily, e.g. by screwing.
- measures for fixing the carrier board in the receiving housing are provided.
- the carrier board can be held in the receiving housing, for example by means of clamping means.
- the carrier board can also be oriented in any manner in the receiving housing, preferably inclined at an angle to the vertical longitudinal orientation of the receiving housing, and can be fixed in the receiving housing.
- the carrier board has a number of openings for warm air dissipation directly next to the through-openings for the straight sections of the tubular heater and in areas at a distance from the through-openings.
- the openings can be of any size, number and spacing from one another.
- 1 denotes the housing of a frost monitor, which has supply air openings 2 in the base area and 3 exhaust air openings 4 in the front side for a convection air flow passing through the receiving housing 1.
- a board 5 (Fig. 4) is fixed, which serves as a support for a tubular heater 6 (Fig. 2,3).
- the tubular heater 6 has two straight sections 6 ', 6' 'which, for fixing the tubular heater 6 on the carrier board 5, pass through through openings 7 of the carrier board 5 and on the carrier board 5, e.g. are held by screw 8 or clamp body.
- the straight sections 6 'and 6' 'of the tubular heater 6 are followed by two deflection bends 9 and 10 at one end and a single deflection bend 11 in the area of the other end.
- the deflection bend 9, 10 and the straight pipe sections 6 ′, 6 ′′ essentially extend, as shown in FIG. 4, in parallel planes to one another, while the deflection bend 11 is directed obliquely to the parallel planes.
- the straight pipe sections 6 ', 6'' have a first thermally inactive zone 16 at the ends facing the network connections 12, which on the one hand ensures damage-free fastening of the tubular heating element 6 to the support plate 5 and which also supports the uniformity of heat emissions to the convection air flow.
- the two deflection bends 9, 10 are offset from one another in the longitudinal direction of the tubular heating element 6 and are formed at different distances from the mains connections 12. The transferred training the deflection bend 9, 10 leads to heat emission zones extending largely over a wide area of the tubular heating element 6, which preclude the formation of temperature peaks.
- a number of openings 14 for warm air dissipation are provided directly next to the lead-through openings 7 of the circuit board 5.
- 7 further areas 15 are provided in the support plate 5 with openings 14 for warm air discharge in addition to the through openings.
