AI Technical Summary
Technical Problem
Existing check valves in cooling and thermal circuits experience significant pressure loss due to turbulence and inefficiencies in medium flow, which affects heat dissipation and overall efficiency.
Method used
A check valve design featuring a closure body with a convex and concave contour that extends opposite to the flow direction, reducing turbulence and optimizing flow by ensuring smooth transitions and continuous guidance through guide ribs, thereby minimizing pressure loss.
Benefits of technology
The design significantly reduces pressure loss, enhancing flow efficiency and heat dissipation by increasing laminar flow, particularly on the low-pressure side of cooling or thermal circuits.

Abstract
The present invention relates to a check valve, in particular for a cooling or heating circuit, which can be inserted into a connection opening (26, 27, 28, 29) of a connecting device (21) or a pipe (39), the check valve having a valve closing element (61) with a closing body (65), a closing surface (108) of which abuts against a valve seat (75) in the initial position (62) of the valve closing element (61) and closes the through opening (24), the closing body (65) having at its free end face (101) a concave contour (102) extending from the closing surface (108) in the direction opposite to the movement of the closing body (65) into the operating position (63) and connected to the closing surface (108) by a convex contour (105).
