A perforating system and method for use in a wellbore. A plurality of the stemware suspenders may be mounted on a base plate, to assist in installation of multiple suspenders. The initial position of the offset latch can be placed, for example, approximately in the middle of the determined amplitudes for at least two of the trajectories. The structure allows the outer surface of the tubing to have increased cooling at a particular liquid flow rate, which allows more heat transfer capability to a coupled system or vehicle component as compared with liquid coolers without the structure.
