Description
Technical field
The utility model relates to a kind of radiator of inverter type welder, is used for inverter type welder.
Background technology
The course of work of inverter type welder, to obtain a more level and smooth direct current after three-phase or single-phase 50Hz industrial frequency AC electric rectification, the filtering, inverter circuit becomes this direct current in the alternating current of 15～100kHz, after the step-down of intermediate frequency main transformer, rectifying and wave-filtering obtains the output of direct current stably welding current (or the alternating current of required frequency is exported in inversion again) again.The control circuit of inverter type welder is comprised of input circuit and output circuit etc., input circuit comprises inverter circuit, output circuit comprises rectification circuit, inverter circuit is comprised of elements such as IGBT pipes, rectification circuit is comprised of elements such as commutation diodes, and in the course of the work, IGBT pipe and commutation diode can generate heat, therefore radiator need to be set, IGBT pipe and commutation diode are attached to respectively on the IGBT pipe installing zone and commutation diode installing zone of radiator.Prior art becomes the radiator of welding machine and is made by metals such as aluminium alloys, be monolithic construction, in order to prevent IGBT pipe and commutation diode short circuit, need between commutation diode and radiator, establish silastic fabric, make the insulation of commutation diode and radiator, and because the existence of silastic fabric so that the contact-making surface of commutation diode and radiator significantly reduces, has affected the radiating effect of radiator to commutation diode.
The utility model content
Technical problem to be solved in the utility model is to overcome deficiency of the prior art and radiator that the inverter type welder of a kind of reasonable in design, good heat dissipation effect is provided.
The technical scheme in the invention for solving the above technical problem is: a kind of radiator of inverter type welder, this radiator comprise stator and a plurality of fin; Fin is plate shape, fixes with stator, forms the air channel between two fin; Stator is provided with IGBT pipe installing zone and commutation diode installing zone; It is characterized in that: described radiator is divided into first paragraph and the second segment that separates, and arranges before and after first paragraph and the second segment; IGBT pipe installing zone is located on the first paragraph, and the commutation diode installing zone is located on the second segment.First paragraph separates with second segment and does not contact, the IGBT pipe that is attached to like this IGBT pipe installing zone and the commutation diode that is attached to the commutation diode installing zone just can short circuits, commutation diode can directly be attached on the radiator, no longer need silastic fabric, increase the contact-making surface of commutation diode and radiator, strengthened radiating effect; Arrange before and after first paragraph and the second segment, cooling air can out enter second segment afterwards from first paragraph.
The utility model also comprises baffle plate, and baffle plate one end and first paragraph are fixed, and the other end and second segment are fixed; Described baffle plate is made of plastics.The baffle plate insulation that plastics are made works the effect of keeping out the wind, and reduces the leakage from first paragraph cooling air out, and has played first paragraph and second segment are strengthened fixing effect.
The utility model compared with prior art has following advantage and effect: reasonable in design no longer needs silastic fabric, the contact-making surface of commutation diode and radiator, good heat dissipation effect.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the left TV structure schematic diagram of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Referring to Fig. 1 and Fig. 2, the utility model embodiment comprises stator 1 and a plurality of fin 2.Fin 2 is plate shape, and is fixing with stator 1, forms air channel 3 between two fin 2.
The utility model is divided into first paragraph 4 and the second segment 5 that separates, and first paragraph 4 and second segment 5 front and back arrange.IGBT pipe installing zone 6 is located on the first paragraph 4, specifically is positioned on the part of first paragraph 4 in the stator 1.Commutation diode installing zone 7 is located on the second segment 5, specifically is positioned on the part of second segment 5 in the stator 1.First paragraph 4 separates with second segment 5 and does not contact, the IGBT pipe 9 that is attached to like this IGBT pipe installing zone 6 and the commutation diode 10 that is attached to commutation diode installing zone 7 just can short circuits, commutation diode 10 can directly be attached on the radiator, no longer need silastic fabric, increase the contact-making surface of commutation diode 10 with radiator, strengthened radiating effect.First paragraph 4 and second segment 5 front and back arrange, and cooling air can out enter second segment 5 afterwards from first paragraph 4.
