Benefits of technology

This technology improves heat treatment by making more efficient uses of multiple boat systems within an oven tubular structure while reducing deviations from its original design dimensions or causing issues such as product failure due to excessively large temperature differences between different parts inside the vessel.

Problems solved by technology

This patented technical solution described in the current state text discusses the challenges faced when producing large quantities (megawatts) of photocellular solar cells at once due to their low productivity compared to other types of batteries. Existing methods involve adding more expensive components or replacing existing ones overtime, leading to increased maintenance expenses and decreased power supply capabilities. Therefore, reducing these issues becomes important from both economic perspective and customer satisfaction standpoint.

Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] see figure 2 , the double-combined multi-frame graphite boat shown in the figure includes two multi-frame graphite boats 10, 20, of course it is not limited to two multi-frame graphite boats 10, 20, and can be connected in series by more than two multi-frame graphite boats .

[0027] Each multi-frame graphite boat 10, 20 is a five-frame graphite boat with very mature technology, and the loading capacity of each five-frame graphite boat is within 450.

[0028] The present invention is characterized in that: the double-piece multi-frame graphite boat is connected in series by two multi-frame graphite boats 10, 20, and passes between the ends of two adjacent graphite boat sheets 11, 21 of each multi-frame graphite boat 10, 20 A graphite spacer 12, 22 and two bolt rods 14, 24 and nuts 15, 25 are connected. The ingenious use of two multi-f

Abstract

The invention discloses a semi-detached multi-frame graphite boat. The semi-detached multi-frame graphite boat comprises two multi-frame graphite boats, wherein the tail ends of adjacent two graphiteboat pieces of each multi-frame graphite boat are connected through a graphite partition block and a bolt rod. The semi-detached multi-frame graphite boat is characterized in that each graphite partition block is provided with at least one gas flow through hole, which communicates with a gas flow channel between adjacent two graphite boat chips of the multi-frame graphite boat, and a conductive insertion rod hole; adjacent two graphite partition blocks in the two multi-frame graphite boats are electrically connected through a conductive insertion rod, and the conductive insertion rod is inserted into a conductive rod insertion rod hole of each graphite partition block; and the gas flow channels on the two adjacent graphite partition blocks on the two multi-frame graphite boats communicatewith each other. The two graphite boats are delicately matched for use in a furnace tube, so that the yield is increased, expansion is reduced to prolong accumulated errors, and the rate of defectiveproducts is reduced.
