Embodiment Construction
[0017] In order to better understand the technical solution of the present invention, the following will be described in detail through specific examples:
[0018] see Figure 1-Figure 4 , the present invention, a water cooling block used for high-voltage high-power thyristor fixtures, is box-shaped, and a water inlet 1 and a water outlet 2 are arranged on the same side of the box body, and a water inlet 1 and a water outlet 2 are arranged between There are several openings 7, and the water inlet 1, the water outlet 2 and the several openings 7 all extend to the inside of the box body to extend corresponding parallel pipes 3 parallel to one side of the box body; the other side of the box body is provided with several openings 7, so The openings extend corresponding vertical pipes 4 perpendicular to the above-mentioned parallel pipes to the inside of the box body. The vertical pipes 4 bridge each parallel pipe 3 and form passages with the parallel pipes. The pipes are threaded ...

The invention discloses a water cooling block for a high-voltage high-power silicon controlled rectifier clamp. The water cooling block is in a box shape, a water inlet and a water outlet are formed in the same side of a box body, a plurality of openings are formed between the water inlet and the water outlet, and the water inlet, the water outlet and the openings extend into the box body to formcorresponding parallel pipelines parallel to one side of the box body; a plurality of openings are formed in the other side of the box body; the openings extend towards the interior of the box body toform corresponding vertical pipelines vertical to the parallel pipelines; the vertical pipelines are connected with the parallel pipelines in a bridging mode to form passageways with the parallel pipelines, the pipelines are all of a threaded hole technology, bolts are screwed in the vertical pipelines and located in the passageways, the parallel pipelines cannot be blocked by the bolts, and allopenings except the water inlet and the water outlet need to be sealed when the box body is formed. Internal water channels are threaded holes, the heat dissipation capacity is improved, the bolts arescrewed into pipelines, the water flow direction is controlled, and the heat dissipation effect is improved.
Description
technical field [0001] The invention relates to a thyristor fixture used in the field of electronic components, in particular to a water cooling block thereof. Background technique [0002] Thyristor is a high-power electronic component. In the automatic control system, it can be used as a high-power drive device to control high-power equipment with low-power controls. It has been widely used in AC and DC motor speed control system, power adjustment system and servo system. [0003] As a high-power electronic component, the thyristor is usually in the working state of high current and high voltage. During this period, the thyristor will generate a lot of heat. How to transfer the heat well is directly related to the thyristor. The key to its own life and the reliability of the entire electrical system. However, the heat dissipation of the thyristor itself cannot meet the requirements of use, so how to dissipate the heat of the thyristor is the main goal of technicians at p...
