Cooling device with a guide sleeve

A cooling device with a heat exchanger unit through which air can flow and at least one fan that is arranged on the heat exchanger unit that generates an airflow through the heat exchanger unit,

• wherein the heat exchanger unit has a front face through which the air can flow which points toward the fan and which is covered in portions by the fan, so that the front face is divided into a first subface that is at least partially covered by the fan and a second subface that is free of the fan,
• wherein the fan is offset or spaced apart from the heat exchanger unit in an axial direction (X),
• wherein the cooling device has a guide sleeve, which is arranged between the heat exchanger unit and the fan, so as to close, at least in portions, a radial gap present between the fan and the heat exchanger unit,
• wherein the guide sleeve forms a flow channel leading from an air outlet of the fan to the first subface of the front face, and fluidically connects the air outlet of the fan to the first subface of the front face and fluidically separates the same from the second subface;
• wherein the fan has a wall on a heat exchanger side which extends in a circumferential direction (U) and overlaps with the guide sleeve in the axial direction (X), so that the guide sleeve covers the wall of the fan in the circumferential direction (U) or the wall of the fan extends around the guide sleeve in the circumferential direction (U);
• wherein an axial gap is formed between the guide sleeve and the wall of the fan,
• wherein axial movement of the fan or the wall of fan due to oscillation or vibration of the fan may freely occur through the axial gap relative to the guide sleeve.
