A modular heat exchanger comprises heat exchange modular units 100 having at least one elongate conduit 101 having at least one elongate aperture 201, and a connection means 102 provided at the aperture 201 enabling the modular units 100 to be assembled together. The conduits 101 may be rectangular and have one (fig 3) or more (fig 4) internal channels communicating with the apertures 201 and may have integral or non-integral fins (fig 8) disposed on one or more external face of the conduit 101. The connection means 102 may be circular or rectangular and connected to the conduit 101 by brazing, welding or an adhesive and may comprise raised lips 103, 104 defining a groove 105 which may receive an o-ring to seal with mating connection means 102. The connection means 102 may define an internal wall 106 which forms a fluid reservoir, have three equally spaced holes 107 for receiving a threaded rod to secure the units 100 together and may be arranged at an angle to an adjacent connection means 102 (fig 7). The lips may be configured in a tongue and groove arrangement so that units 100 nest together. The units 100 may be spaced apart by at least one detachable spacer and the connection means 102 may be sub-divided into a plurality of reservoirs for a plurality of fluids. |
