Abstract: A heat dissipation system adapted to dissipate heat for an electronic device includes a tank, a first heat exchanger, and a fluid delivery device. The tank includes a first zone and a second zone. A cooling fluid is located in the first and second zones. The electronic device is adapted to be disposed in the first zone and immersed in the cooling fluid. The first heat exchanger is located at a junction of the first and second zones to reduce a temperature of the cooling fluid. The cooling fluid flows from the first zone to the second zone through the fluid delivery device. The cooling fluid is adapted to flow to the first zone from the second zone after passing through the first heat exchanger, so as to dissipate heat for the electronic device, and then flows to the second zone through the fluid delivery device, such that a cycle is formed.

Abstract: A holding device includes a frame module and an accommodation unit. The frame module includes a plate body and two lateral plates oppositely disposed on the first plate body. A placement area is collectively defined by the plate body and the lateral plates. Two protrusions are respectively provided on the lateral plates. The accommodation unit includes a tray and two elastic plates. The tray is slidably located within the placement area, and an accommodation space is defined between two opposite sides of the tray. Each elastic plate is elastically connected to one of opposite sides of the tray. When the tray is moved after a load is placed within the accommodation space, the protrusions respectively push the elastic plates towards the accommodation space so that the load is toollessly fastened between the elastic plates.
