IMPROVEMENTS IN AND RELATING TO HEAT EXCHANGERS
A tubular heat exchanger is described in which the tubes are arranged on an annulus within a casing. If the heat exchanger is used in a nuclear power plant, the cooling gas from the reactor is circulated through the casing and the water is circulated through the tubes. The tubes are supported in places by radially extending walls of the support member which extends through the annulus in an axial direction with respect to the casing. The radially extending walls divide the space between the tubes and the support member into a number of separate flow channels extending in the general direction of the axis of the casing. The walls and the tubes are disposed at an angle to one another. The tubes may be helically disposed with respect to the axis of the casing and the radially extending walls may be straight or the tubes may be straight and the walls may be helical. For the former tube arrangement the fluid is admitted to the tubes from an annular chamber at one end of the casing and leaves the tubes by an annular chamber at the other end of the casing; the other fluid flows over the tubes in the opposite direction. For the latter tabe arrangement the fluid flows through the support member and into the inlet header from which it enters the tubes and flows in the reverse direction through the tubes to an outlet header; the other fluid flows through the casing and over the tubes.
