Description

Technical Field

[0001] This utility model relates to the field of short-arc xenon lamp technology, specifically to an anode structure for a short-arc xenon lamp. Background Technology

[0002] The anode of a water-cooled short-arc xenon lamp is a composite, forced liquid-cooled structure designed specifically for dissipating huge heat loads. Its anode has a cooling channel inside, which, together with a deionized water cooling circulation system, can dissipate the heat at the anode end of the short-arc xenon lamp, thereby maintaining itself within the operating temperature range, ensuring arc stability and preventing itself from melting or excessive evaporation. The anode structure of the water-cooled short-arc xenon lamp mentioned above is an example.

[0003] In some water-cooled short-arc xenon lamps, the anode structure uses an internal cavity as a cooling channel. However, the heat transfer effect of deionized water inside the anode body is insufficient, resulting in poor heat dissipation of the anode body. Therefore, an anode structure for short-arc xenon lamps is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an anode structure for a short-arc xenon lamp, which solves the problem mentioned above where insufficient heat transfer effect of deionized water inside the anode body leads to poor heat dissipation of the anode body.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An anode structure for a short-arc xenon lamp includes an anode connector, an anode body, a heat dissipation sleeve, and heat dissipation fins. The anode body is located at the left end of the anode connector. The anode body includes an anode seat, a liquid inlet chamber, a liquid outlet chamber, an anode column, an outer spiral channel, a direct current channel, an anode cylinder, and an inner spiral channel. The anode seat has a liquid inlet chamber and a liquid outlet chamber inside. The outer spiral channel is located on the outside of the anode column. The direct current channel is located inside the anode column. The inner wall of the anode cylinder has an inner spiral channel. A heat dissipation sleeve is fixedly installed on the outside of the anode seat. Several heat dissipation fins are arranged in a ring-shaped interval inside the heat dissipation sleeve.

[0007] Preferably, the installation gap between the anode seat, anode column, and anode cylinder is fixedly assembled by welding, and the outer spiral channel on the outside of the anode column and the inner spiral channel on the inner wall of the anode cylinder together form a spiral cooling channel.

[0008] Preferably, a delivery pipe is fixedly installed inside the anode seat, inside the heat dissipation sleeve, and inside the anode connecting seat, and a connecting pipe head is fixedly connected to the right end of the delivery pipe.

[0009] Preferably, the left end of the delivery pipe at the rear end is fixedly connected to the inside of the liquid inlet chamber, and the left end of the delivery pipe at the front end is fixedly connected to the inside of the liquid outlet chamber.

[0010] Preferably, the liquid inlet chamber is connected to the rear right end of the spiral cooling channel, the front left end of the spiral cooling channel is connected to the DC channel, and the right end of the DC channel is connected to the inside of the drain chamber.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, an anode connector, an anode body, a heat dissipation sleeve, and heat dissipation fins are provided. An inlet chamber and a outlet chamber are machined inside the anode seat. An outer spiral channel and a direct current channel are machined on the outer side of the anode column. An inner spiral channel is machined on the inner wall of the anode cylinder. The installation gaps between the anode seat, anode column, and anode cylinder are fixedly assembled by welding. A heat dissipation sleeve is fixedly installed on the outer side of the anode seat.

The left end of the delivery pipe at the rear end is fixedly connected to the inlet chamber, and the left end of the delivery pipe at the front end is fixedly connected to the outlet chamber, forming a spiral cooling channel located in the anode body. Combined with the heat dissipation sleeve and heat dissipation fins, this provides a good composite heat dissipation effect for the anode body. Attached Figure Description

[0024] Workflow: This utility model provides an anode heat dissipation structure for a short-arc xenon lamp.
