A liquid cooling apparatus for cooling an inversely mounted electronic component, includes a casing defining a receiving room therein, a diaphragm, a partition plate forming a nozzle thereon, and a piezoelectric element attached to the diaphragm in such a manner that that a vibrating direction thereof is perpendicular to the diaphragm. The diaphragm is arranged in the receiving room and divides the receiving room into a top first chamber and a bottom second chamber isolated from each other. The partition plate is arranged in the first chamber and divides the first chamber into an upper region and a lower region. The lower region is filled with a working fluid. When the diaphragm is driven to vibrate upwardly by the piezoelectric element, the diaphragm pushes the working fluid in the lower region of the first chamber to the upper region of the first chamber via the nozzle.

A Diastasis Recti Splinting Garment is described which includes a plurality of attached torso straps and pelvic straps which the user wraps around their body and connects to the garment so as to approximate the 2 sides of the abdominal wall, providing support to the linea alba and fascial sheathes to allow for tissue healing. Furthermore, the adjustable angled straps encircle the torso and pelvis of the user to restore the integrity of the core, providing stability to the ribcage, spine and pelvis. Restoring the integrity of the core lends itself to optimal activation of the deep core stabilizers, including the abdominal muscles as well as the musculature of the pelvic floor, back, and diaphragm. This in turn aids in dynamic stability of the spine, ribcage and pelvis. This allows maximum support of the diastasis recti, consequently facilitating tissue healing through balancing intra-abdominal pressure, while still supplying support to the vulnerable pelvic floor and stability to the spine, ribcage and sacroiliac joints.
