Description
Technical field
The utility model relates to heat abstractor, is specifically related to the direct insertion high-power components heat abstractor that is welded.
Background technology
The type of existing high-power components radiator structure is more, it is to adopt double panel structure that a kind of usual way is arranged, the paster high-power components is welded on the aluminium base heating panel front that a slice is coated with copper pad separately, aluminium base heating panel is connected with circuit board by the blister copper post, transmit big electric current, and by row's pin transfer control signal between aluminium base heating panel and circuit board, thereby realize that two plates connect purpose.But, since have on the circuit board relay, big electrochemical capacitor equal-volume more greatly, highly higher device, so two plate spacing distances are far away, so the blister copper post is long, cost improves, and the blister copper post during by big electric current conduction loss also can increase; Secondly, control signal wire is more between circuit board and the aluminium base heating panel, and manufacturability is bad, also is easy to generate cross-interference issue between line; After the welding of two plates has been assembled, in case break down, check, keep in repair even change all very inconvenience.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of direct insertion high-power components heat abstractor that is welded.
In order to address the above problem, according to the technical solution of the utility model, a kind of direct insertion high-power components heat abstractor that is welded, comprise aluminium base heating panel, heat dissipation base, circuit board, it is characterized in that: the middle part or the front end of described heat dissipation base are provided with heat conduction, four angles at heat dissipation base are provided with support column, and the heat conduction muscle is all vertical with heat dissipation base with support column; Described circuit board and heat dissipation base be arranged in parallel, and are arranged on the top of heat conduction muscle, circuit board by screw on support column; The metal covering of direct insertion high-power components is close on the aluminium base heating panel, aluminium base heating panel is fastened on the heat conduction muscle by screw, corresponding position with the pin that direct insertion high-power components is installed on circuit board is provided with via pad, and the pin of straight cutting high-power components passes via pad and is electrically connected with circuit board.Since utilize the pin of straight cutting high-power components to replace existing row's pin, blister copper post, with low cost, good manufacturability, and, there is not long lead-in wire, reduce cross-interference issue between line, and reduced the big current lead-through loss on the blister copper post; Simultaneously, because aluminium base heating panel do not block by circuit board,, very convenient if will debug, fault inquiry and maintenance.
According to a kind of preferred version of a kind of direct insertion high-power components heat abstractor that is welded described in the utility model, described heat dissipation base and heat conduction muscle and support column are integrated, and make the utility model good manufacturability, have reduced operation, have reduced cost.
According to a kind of preferred version of a kind of direct insertion high-power components heat abstractor that is welded described in the utility model, between aluminium base heating panel and heat conduction muscle, be provided with heat-conducting silicone grease, heat-conducting silicone grease is set is beneficial to heat radiation.
According to a kind of preferred version of a kind of direct insertion high-power components heat abstractor that is welded described in the utility model, described heat dissipation base is provided with the heat radiation groove.
The beneficial effect of a kind of direct insertion high-power components heat abstractor that is welded described in the utility model is: the utility model has utilized the pin of straight cutting high-power components to replace existing row's pin, blister copper post, with low cost, good manufacturability, low in energy consumption, installation, debugging, easy to maintenance have application promise in clinical practice.
