Title (EN) PUMP COOLING SYSTEMS
(FR) SYSTÈMES DE REFROIDISSEMENT DE POMPE
Abstract:
(EN) A pump cooling system may include a cooling body (24) to be fitted to a pump housing (14) to receive heat from the pump housing via a heat conducting path (44) between the cooling body and pump housing. The cooling body (24) may have a passage (26) through which, in use, a cooling fluid is passed to conduct heat away from the cooling body. The pump cooling system includes a cooling control mechanism configured to provide a gap in the heat conducting path (44) at pump operating temperatures below a predefined temperature so heat conduction from the pump housing to the cooling body is interrupted.
(FR) La présente invention concerne un système de refroidissement de pompe comprenant un corps de refroidissement (24) destiné à être monté sur un corps de pompe (14) pour recevoir de la chaleur provenant du corps de pompe par l'intermédiaire d'un trajet de conduction de chaleur (44) entre le corps de refroidissement et le corps de pompe. Le corps de refroidissement (24) peut avoir un passage (26) à travers lequel, lors de l'utilisation, un fluide de refroidissement circule pour conduire la chaleur à distance du corps de refroidissement. Le système de refroidissement de pompe comprend un mécanisme de commande de refroidissement conçu pour fournir un espace dans le trajet de conduction de chaleur (44) à des températures de fonctionnement de pompe inférieures à une température prédéfinie de sorte que la conduction de chaleur du corps de pompe au corps de refroidissement soit interrompue.
