DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to apparatuses or devices designed to cool the air contained in a room or an enclosure (in the wide sense), and it is particularly concerned with cooler apparatuses suitable for being mounted on vehicles, in particular for the cabs of earth-moving vehicles.
PRIOR ART
In general, a cooler apparatus comprises a housing in which there are mounted a heat exchanger having a cooling fluid passing therethrough, and a fan for circulating air. The housing of the apparatus may be organized to have an inlet for sucking in air to be treated and an outlet for delivering treated air. The inlet and the outlet of the housing then communicate with openings formed in the enclosure on which the cooler apparatus is to be mounted.
Given that as the heat exchanger is at a temperature lower than that of the air contained in the cab, moisture is deposited in the form of condensation water or frost on the surfaces of the heat exchanger. The condensates that result from air passing through the heat exchanger are generally collected by means of a recovery tray disposed beneath the heat exchanger.
Depending on the structural characteristics of an enclosure, such a cooler apparatus is installed relative thereto either above, or below, or on one side, and either inside or outside the cab. To be able to satisfy the various possible mounting positions, it is the practice to manufacture four types of cooler apparatuses each capable of collecting and evacuating condensates.
Furthermore, when the cooler apparatus is fitted to a vehicle that is liable to be tilted, it is clear that condensates cannot be collected and evacuated using conventional devices. Furthermore, in order to avoid damaging electronic equipment or the enclosures to be treated, it is essential that no liquid (water, cooling liquid, etc.) can escape from the treatment box via the openings for taking up or delivering up treated air.
There is thus a need for a cooler apparatus capable of being adapted to various different positions while being capable in each position of collecting and evacuating condensates.
SUMMARY OF THE INVENTION
The present invention therefore seeks to achieve the above objects by proposing a cooler apparatus capable of collecting and evacuating condensates whatever the position in which the cooler apparatus is mounted, and regardless of whether it is mounted on the outside or the inside of an enclosure (in the wide sense).
To achieve this object, the cooler apparatus of the invention comprises a housing provided internally with fixed means for collecting and evacuating condensates in any position of the cooler apparatus when mounted on or in the enclosure.
Implementing such collecting and cooling means in association with the housing of the cooler apparatus makes it possible to obtain a cooler unit that is universally mountable and that is compact.
According to an advantageous characteristic, the means for collecting and evacuating condensates are constituted at least by: to at least one condensate evacuation orifice referred to as a "horizontal position" orifice; and the inside of the housing, between the heat exchanger and the suction inlet; height of the heat exchanger and in the opposite direction to the deflector; and position" orifice.
