Abstract

The invention relates to an arrangement in a heating fan (1). The fan comprises an elongated casing (6) and in this a heat exchanger (4) and fan element (5) are designed to draw in ambient air through the openings (6a) along one side of the casing (6). After heating in the heat exchanger (4) the air is allowed to pass out through openings (6b) along the opposite side of the casing (6). The heating fan (1) is intended for wall mounting horizontally in an area close to the floor (7) in a bus. The inlet openings (6a) then point upwards and the outlet openings (6b) downwards. The casing (6), on the side (6c) intended to be fitted towards the bus wall (2), along at least one part of its length has at least one opening (6d) located on this side at the bottom. Through this opening a proportion (10) of the air heated by the heat exchanger (4) passes upwards along the wall (2) on which the heating fan (1) is mounted.

Description

Device at a heating fan
The present invention relates to an arrangement according to the pre-characterising clause of the patent claims attached.
Although the heat balance in an enclosed space, such as a bus, is normal, the tem- perature of the interior climate may be felt to be unsatisfactory. One reason for complaints are draughts, another reason being so-called temperature radiation asymmetry.
The term "draught" refers to a local cooling of the skin caused by air movements. It has been possible to establish through experiments that if the temperature of the sur- rounding air is increased commensurately with an increase in the air velocity, relatively high air velocities can be tolerated without serious discomfort.
As bus passengers, we consequently feel it is something of an advantage if there is a certain draught on a hot summer's day.
It is quite a different matter if one lingers close to a cold surface such as a cold wall or window or close to a warm surface for a longer period. It may be observed that persons generally experience some thermal discomfort in the event of cold radiating f om the side or heat radiating from above. By contrast, we can tolerate large varia- tions in cold radiating from above and heat radiating from the side.
This is one reason why in known heating fans of the type mentioned in the introductory part the heated air is expelled low down, that is to say near the floor.
The object of the present invention is to achieve improved comfort in a heating fan of the type stated in the introductory part. This is achieved in that the invention has the features specified in the characterising part of the claim.
The invention will be explained in more detail with reference to the attached draw- ing. which in diagrammatic form shows a cross-section through a heating fan according to the invention installed in a bus.
In the drawing 1 generally denotes a heating fan fitted to the wall 2 of a bus, for example under or between the passenger seats 3. The heating fan 1 comprises an elon- gated heat exchanger 4, which in a manner known in the art constitutes the pipe connection to the bus heating system. In the drawing a number of fans 5 are arranged along and above the heat exchanger 4, but it will be obvious that the location and the number of fans may be varied without departing from the scope of the invention.
The heat exchanger 4 and the fans 5 are enclosed in a casing 6. This is provided along its length with openings 6a, 6b arranged at the top and bottom. The fans are designed to draw air in through the openings 6a at the top, to allow it to pass through the heat exchanger 4 and to expel the air thus heated out through the openings 6b at the bottom near the floor 7 of the bus. In the drawing the intake air to the heating fan 1 is marked by arrows 8 and the heated air from the heating fan 1 by arrows 9.
According to the invention the casing 6, along at least one part of its length on one side 6c intended to face the wall 2 of the bus, has at least one opening 6d at the bottom. The said opening 6d is designed to allow a proportion of the air heated by the heat exchanger 4 to flow upwards along the wall 2. This proportion of heated air is marked by arrows denoted by 10. As stated in the introductory part, this heating of the wall 2 constitutes compensation for the equivalent temperature reduction as a result of the admission air to the heating fan. In order to ensure a certain gap between the heating fan 1 and the bus wall 2, there is a spacer element 11 on the side 6c of the casing 6.

Claims

Claims
1. An arrangement in a heating fan (1) comprising an elongated casing (6) and in this a heat exchanger (4) and fan element (5) designed to draw in ambient air through the openings (6a) along one side of the casing (6), which air after heating in the heat exchanger (4) is allowed to pass out through openings (6b) along the opposite side of the casing (6), the heating fan (1) being intended for wall mounting horizontally in an area close to the floor (7) in a bus, with the inlet openings (6a) pointing upwards and the outlet openings (6b) downwards, characterised in that the casing (6), on the side (6c) intended to be fitted towards the bus wall (2), along at least one part of its length has at least one open- ing (6d ) located on this side (6c) at the bottom, through which opening a proportion (10) of the air heated by the heat exchanger (4) is intended to pass upwards along the wall (2) on which the heating fan (1) is mounted.
2. The arrangement according to Claim 1, characterised in that on the side (6c) there is a spacer element (11), the function of which is to ensure a gap between the heating fan (1) and the bus wall (2).
