Cooling water, plate apparatus for.-Apparatus for cooling indirectly by means of sea water or other impure water the fresh cooling-jacket water of motor boat or other engines comprises metal plates l clamped between frames T, t, to form alternate chambers d for the jacket water supplied through a pipe H and discharged through a pipe at the bottom, and chambers F for the impure water, supplied by a pipe P and discharged through a pipe L. The plates l and frames T have registering openings h, h<1>, h<11>, Fig. 3, and i, i<1> i<11>. Fig. 1, and the frames t have openings m and lugs o, o<1>, Fig. 2. A tube r having a closed head r' passes through the circular openings of the. frames and plates. and is secured by a bolt y, while an annular hollow boss u on the outlet pipe L is secured over the tube r by a nut w. The plates and frames are secured together by bolts a around the edges. Triangular holes are formed in the lower corners of the frames and plates, the hole c in the plate T being in communication with the interior through slots in a diagonal web b, while the other web b<1> of this frame is without such slots. Similarly, one hole f of the frame t communicates with the interior by slots in a web e adjacent an imperforate web b<1> of the frame T, the other web e<1> of the frame t being closed. The impure cooling-water entering by the pipe P passes through the corners of the plates and frames and rises through the chambers F, passing away through the openings i<1>, h<1> and the pipe L, while the hot jacket-water flows through ports of the tube r and into the chambers d. Glycerine or other agent may be added to the jacket water to render it non-freezing.
