An evaporator (10) includes a substantially plate-like body member (12) defining an operatively outer surface (14) and an operatively inner surface (16), both surfaces (14, 16) being substantially smooth to inhibit detritus from attaching to the body member (12). The body member (12) is shaped to cause incoming fluid from which heat is to be extracted, in use, to follow an extended, circuitous path past the body member (12) initially along the outer (surface 14) of the body member (12) prior to the fluid impinging on the inner surface (16) of the body member (12). |
