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.
