Abstract:
1. A heat exchanger modular unit ( 100 ) capable of being assembled with other heat exchanger modular units to form a heat exchanger of varying shape and size, said modular unit comprising: an elongate conduit ( 101 ) having at least one longitudinally extending internal bore open at both ends ( 201 , 400 ); and connection means ( 102 ) formed non-integrally with and bonded to said conduit, positioned at the open ends of said conduit to interconnect the internal bores of each conduit and enable said modular units to be connected together via each said connection means in internal fluid communication; wherein each said connection means comprises an external surface ( 108 ), an internal surface ( 106 ) defining an internal cavity, an upper surface ( 202 ), a lower surface ( 307 ) and a plurality of bore holes ( 107 ) each extending from the upper surface to the lower surface and located between said external and internal surfaces, at least one lip ( 200 ) formed on the upper ( 202 ) surface and at least one groove ( 105 ) defined by first and second lips ( 103 , 104 ) formed on the opposed lower ( 307 ) surface, wherein each bore hole ( 107 ) intersects the at least one lip ( 200 ) at the upper ( 202 ) surface and also the first and second lips ( 103 , 104 ) at the lower ( 307 ) surface, the at least one lip ( 200 ) and the at least one groove ( 105 ) being configured to mate, respectively, with a corresponding groove and a corresponding lip of respective adjacent modular units ( 100 ) of the plurality thereof, for preventing fluid from egressing between adjacent connection means when said plurality of modular units are assembled together.
