Patent number: 11659687Abstract: The present invention provides a stack-type vertical heat dissipation device comprising an evaporator unit and a condenser unit. The evaporator unit has a side configured for direct or indirect contact with, and thereby receiving heat from, a high-temperature device in order for the heat to convert a heat conduction medium inside the evaporator unit into a gaseous state. The condenser unit is stacked on a top side of a housing of the evaporator unit, and is provided therein with a flow channel that is in communication with the evaporator unit and allows passage of the heat conduction medium so that the heat conduction medium is able to return to the evaporator unit under a force of gravity after condensing from the gaseous state into a liquid state and thereby complete a thermal cycle.Type: GrantFiled: December 22, 2020Date of Patent: May 23, 2023Assignee: MAN ZAI INDUSTRIAL CO., LTD.Inventors: Cheng-Chien Wan, Cheng-Jui Wan, Chun-Hsien Su, Hui-Fen Huang

Patent number: 8147109Abstract: A heat dissipation device of a vehicle lamp and an interposing element thereof are provided. The heat dissipation device is installed in a lamp room which is divided by the interposing element into a front partition and a rear partition. A heat sink is installed in the interposing elements. An air feeding fan is disposed in an air feeding channel of the interposing element, for drawing air in the front partition to the rear partition through the air feeding channel. Further, a back flow fan is disposed in the rear partition, for drawing air in the rear partition to the front partition through a back flow channel. Whereby, the air in the front partition is cooled down through an external air flow passing through the lamp cover. Then, the heat sink dissipates heat of the air flow with the relatively low temperature in the front partition to the rear partition.Type: GrantFiled: November 23, 2009Date of Patent: April 3, 2012Assignee: Man Zai Industrial Co., Ltd.Inventors: Cheng-Feng Wan, Hao-Hui Lin, Su-Chen Hu, Chen-Jung Chen, Hui-Fen Huang
