Abstract: Device for cooling fluid, comprising: an inlet for infeed of the fluid; a through-flow space through which the fluid flows; a discharge for outfeed of the fluid; and a number of pipes containing coolant which extend helically in the interior of the through-flow space and the pitch of which is such that the upward angle at least equals the angle of fall of solid particles present in the fluid flow.

Abstract: The present invention provides a device for cooling a warm medium comprising:a vessel wherein a bundle of a number of pipes are disposed and wherein coolant medium flows around the pipe bundle;a pipe plate through which the pipes of the bundle debouch into a reservoir for supply of the warm medium;a support plate mounted at a distance from the pipe plate whereby the pipes are supported and wherethrough the pipes extend; andone or more rings which are each mounted between a pipe and the support plate on the side of the support plate faced to the pipe plate and which are provided with holes for allowing passage of the coolant.
