  • Publication number: 20090044929
    Abstract: A liquid cooling module has a sealed unit and a heat dissipating module connected by multiple flexible pipes. The sealed unit has a contacting surface attached to an electronic element. The heat dissipating module has a radiator, coolant tanks and a pump all mounted compactly together. The radiator has multiple fins and tubes to allow the coolant to flow through and dissipate heat and may have a fan to increase airflow. The coolant tank is formed on the radiator. The pump circulates the coolant along the coolant pipes. Accordingly, the liquid cooling module has a compact structure and the coolant pipes are flexible, so the liquid cooling module can be mounted simply in a computer case, and is installed easily by home users and professionals alike.

  • Patent number: 7466550
    Abstract: An integrated heat dissipating assembly includes two heat sinks, a heat dissipating fan mounted between the two sinks and a body provided below the two heat sinks and the heat dissipating fan. The body is composed of a hollow body, a pump received inside the hollow body and a base attached to a bottom face of the hollow body for conducting heat from a heat source. The hollow body is divided into receiving spaces respectively communicating with water channels of the two heat sinks such that cooling water flowing inside the hollow body and the water channels of the two heat sinks is able to take away heat from the base. The heat is then dissipated by cool air due to the heat dissipating fan.

  • Publication number: 20080266785
    Abstract: A heat dissipator fastening kit includes two retaining bars, at least one and as many as three different brackets and multiple fasteners. The retaining bars are resilient, attach to opposite sides of an appropriate heat dissipator and respectively have two ends. The bracket attaches to a motherboard around a CPU and to the retaining bars and has several embodiments to accommodate different types of CPUs, e.g. AM2, K8, LGA775 or P4, and their motherboards. The fasteners attach the retaining bars to a heat dissipator and the bracket and the bracket to a motherboard. With such an arrangement, the heat dissipator fastening kit will be convenient and easy to use.
