  • Publication number: 20240088417
    Abstract: A cooling system for cooling of a fuel cell assembly, includes a cooling loop for recirculation of a cooling medium, a cooling medium flow line comprising a first cooling medium buffer tank, a first heat exchanger for cooling of the cooling medium, and a second cooling medium buffer tank. The first cooling medium buffer tank is arranged upstream the first heat exchanger so as to allow collection, storing and discharge of cooling medium before it reaches the first heat exchanger. The second cooling medium buffer tank is arranged downstream of the first heat exchanger so as to allow collection, storing and discharge of cooling medium that has passed through and been cooled in the first heat exchanger.

  • Publication number: 20230129602
    Abstract: Removable liquid heat exchanging element (100) for use in a device for temperature control treatment (400) comprising a support structure (300), and a liquid transporter (200) supported by the support structure (300). The removable liquid heat exchanging element (100) is configured to be positioned in a slot (402) in the device for temperature control treatment (400). The liquid transporter (200) comprises an inlet (201) and an outlet (206) and a lumen for liquid transportation. The lumen is at least partially enclosed by a heat exchanging portion (205) of a flexible wall configured to engage a heat exchanging surface (401a, 401b) of the device for temperature control treatment (400). The support structure (300) is configured to engage and partially enclose a portion of the liquid transporter (200) such that an occlusion (203) is formed between the inlet (201) and the heat exchanging portion (205) of the lumen for liquid transportation.

  • Patent number: 10961777
    Abstract: A ladder tube (10, 12) for use in a ladder section of a collapsible ladder (1) is provided. The collapsible ladder comprises several ladder sections (5, 5a-5j), where each ladder section comprises two ladder tubes (10, 12) arranged parallel to each other and interconnected by a rung (20) to form the respective ladder section, and where each ladder tube (10, 12) is telescopically inserted into a ladder tube (10, 12) of a lower section to form the collapsible ladder (1). The ladder tube (10, 12) is characterized in that it has a cross-sectional shape comprising at least one straight section (16) which at each end is connected at an angle larger than 90 degrees to at least one additional section (18) of the cross-sectional shape.
