Abstract: Disclosed herein is a heat dissipation device for a power conversion module. The device includes a casing, a high-heat-dissipation heat sink and a circuit board. The casing includes a heat-dissipation fin unit which has heat dissipation fins arranged at positions spaced apart from each other by predetermined intervals. The casing has a mounting space therein. The high-heat-dissipation heat sink is installed in the mounting space of the casing. The circuit board is coupled to a lower surface of the casing. Therefore, the weight and size of the heat dissipation device can be reduced. In addition, the heat sink and the casing having the heat dissipation fins dissipate heat at the same time, thus enhancing the heat dissipation efficiency. Moreover, in an optimal design, the high-heat-dissipation heat sink is located at a position corresponding to a part which generates high heat so that the heat dissipation efficiency can be maximized.

Abstract: The present disclosure relates to a static mixer for mixing a urea solution and engine exhaust gas. The static mixer includes: an external tube including one end portion connected to an exhaust manifold of a diesel engine, the other end portion connected to an SCR (Selective Catalytic Reduction), and a part with which a urea solution injection adaptor is provided; an internal tube installed inside the external tube so as to have a constant gap between at least a part of an outer wall surface and an inner wall surface of the external tube; and a channel unit comprising a plurality of guiding channels provided inside the internal tube in a longitudinal direction, and having an inlet portion facing a lower end portion of the urea solution injector adaptor. The present disclosure may make the exhaust gas and the urea solution before passing through the SCR pass through the inlet portion and the plurality of guiding channels of the channel unit to form fine and even mixed gas, thereby largely decreasing an amount of nitride oxide (NOx) discharged to the air by improving a catalytic reduction reaction ratio in the SCR.
