Vorliegende Erfindung betrifft eine Kühlvorrichtung, zur Herabminderung der Temperatur des Wassers, welches um die Maschinenzylinder und andere Teile der Motorfahrzeuge zirkuliert, die sehr leicht überhitzt werden. Insbesondere bezieht sich dieselbe auf die Klasse von Kühlvorrichtungen, bei der ein Ventilator mit einer Ringkammer verbunden ist, durch welche das heiße Wasser von denThe present invention relates to a cooling device, to lower the temperature of the water around the engine cylinders and other parts of motor vehicles which are very easily overheated. In particular, it relates to the Class of cooling devices in which a fan is connected to an annular chamber is through which the hot water from the

ίο Maschinen zirkuliert und gekühlt wird, ehe es zum weiteren Gebrauch in dieselben zurückkehrt. ίο machines are circulated and cooled before it returns to them for further use.

Nach der Erfindung werden weitere den Ventilator umgebende Kühlräume oder Kanäle in Verbindung mit Vorrichtungen benutzt, welche den erzeugten Luftstrom direkt auf die Maschinen oder andere zu kühlende Teile leiten.According to the invention, further cooling spaces or channels surrounding the fan are provided used in conjunction with devices that directly apply the generated air flow manage the machines or other parts to be cooled.

Bei Kühlvorrichtungen der bezeichneten Art ist eine zweite Kühlkammer konzentrisch mit der den Ventilator umgebenden Kühlkammer angeordnet und weitere Kühlräume befinden sich vor und hinter dem Ventilator. Kommunizierende Röhren oder Kanäle sind zwischen der Ringkammer und den Nebenkühlräumen vorhanden, und eine Anzahl kurzer Rohre oder Leitungen, welche von dem Raum zwischen den zwei Ringkammern durch einen der Nebenkühlräume gehen, befördern die Luft nach den zu kühlenden Teilen der Maschine. Auf den beiliegenden Zeichnungen ist eine Ausführungsform dieser Erfindung veranschaulicht, und zwar istIn cooling devices of the type indicated, a second cooling chamber is concentric with arranged in the cooling chamber surrounding the fan and further cooling spaces are located in front of and behind the fan. Communicating tubes or channels are between the annular chamber and the auxiliary cooling rooms, and a number of short pipes or lines leading from the space between the two annular chambers through one of the Additional cooling rooms move the air to the parts of the machine to be cooled. An embodiment of this invention is illustrated in the accompanying drawings, namely is

In die äußere Ringkammer a, welche auf dem kastenartigen Bodenteil b angebracht ist, wird 'das heiße Wasser von der Maschine durch das Rohr c mittels der üblichen (nicht dargestellten) Umlaufpumpe getrieben. Durch das Austrittsrohr d wird das gekühlte Wasser von der Kühlvorrichtung nach der Maschine zum wiederholten Gebrauch zurückgeführt, wobei ein gleichbleibender Umlauf leicht aufrechtzuerhalten ist. Bei der dargestellten Ausführungsform der Erfindung ist die äußere Ringkammer α zweckmäßig erheblich kleiner als bisher, und innen ist gleichachsig zu ihr eine zweite Kühlkammer e angeordnet, die in beliebiger Weise an ihrer Stelle gehalten wird. Die Kammer e umgibt hier nahezu den Ventilator f, und die Verbindung zwischen der inneren und der äußeren Kammer α ist mittels kurzer Rohre g, g¹ hergestellt, wobei die ersteren Rohre g an der oberen Seite als .Einlaßrohre von der Kammer α und die letzteren Rohre g¹ an den unteren Enden der Kammer e angeordnet sind und mit dem Bodenteil b in Verbindung stehen. Wie leicht ersichtlich, kann man die Kammer e vollständig ringförmig herstellen und mit Löchern oder ÖS-nungen für den Durchgang der Luft von dem Ventilator f versehen.In the outer annular chamber a, which is attached to the box-like bottom part b , the hot water is driven from the machine through the pipe c by means of the usual circulation pump (not shown). Through the outlet pipe d , the cooled water from the cooling device is returned to the machine for repeated use, with a constant circulation being easy to maintain. In the illustrated embodiment of the invention, the outer annular chamber α is suitably considerably smaller than before, and a second cooling chamber e is arranged on the inside coaxially with it and is held in its place in any desired manner. The chamber e here almost surrounds the fan f, and the connection between the inner and outer chambers α is made by means of short tubes g, g ¹ , the former tubes g being on the upper side as inlet tubes from the chamber α and the latter Pipes g ^{1 are arranged} at the lower ends of the chamber e and are in communication with the bottom part b. As can be easily seen, the chamber e can be made completely ring-shaped and provided with holes or eyelets for the passage of air from the fan f .

Auf der Vorderseite der Kühlvorrichtung befindet sich .ein hohler Deckel h, welcher eine Nebenkammer bildet und eine zentrale öff-On the front of the cooling device there is a hollow cover h, which forms a secondary chamber and a central opening

Claims

tion i for the inlet of cool air into the central part of the fan f has. Short tubes /, j1 connect the cover h with the annular chamber α and the base piece b. So that you can fix it and remove it. of the lid, the pipes j, j1 are provided with flanges k1 which are fastened to the lid h by means of screws, with short pipes I, I1 being provided on the front of the latter ίο which carry the water to or from both sides the flanges guide (Fig. ι and 3). On the rear of the cooling device there is a cover m which, like the front cover h, forms a secondary chamber. An annular chamber η is connected to the chamber a by a channel n1 (FIGS. 1 and 3), to the lower part b by a channel b1 and to the cover m by channels ml (FIGS. 2 and 3). Short pipes or air channels 0 go through the annular chamber η and are in communication with the space between the chambers α and e. As shown, these air ducts are made somewhat tapered. Bearings p for the spindle q of the fan f are attached to the covers h and m. An outlet r enables dirt or other material that has got into the central space to fall out again immediately without damaging the fan. Holes are provided in the top cap s for vapor accumulated in the cooling device to exit, and t is an overflow pipe. The fan f is set in rotation by means of a belt placed around the pulley u (Fig. 3), and the hot water which passes through the pipe c from the machine into the cooling device is cooled as it circulates through the various chambers and channels before it reaches the return pipe d, while the cool air serving to dissipate the heat is driven into and through the space remaining between the annular chambers α and e and through the short pipes or air lines 0 to the machine and other parts to be cooled. In practice it has been found that if the short tubes or air lines 0 are made somewhat conical, as described, the unpleasant noise which otherwise arises when the air is forced through is completely avoided. With the device described, the water is cooled in a very simple and effective manner, a great saving in space is achieved, and by attaching a removable front cover, free access is created which enables lubrication and cleaning.
