Heat exchanger end connection box - has coaxial connections to exterior and also to internal parallel tube groups

摘要

The collector box is for heat exchangers using heat or cold conveying liquids. These flow in parallel tubes with fins arranged in blocks. The box fits the blocks and ends of the tubes and has three zones. The first two connect with two tube blocks and with the third zone. The third zone has two holes to the exterior and facilities for the other zones to fill functions between the fluid inlet and outlet for the heat exchanger. The holes to the exterior and between the others are coaxial.
