It is provided by the utility model a kind of in HTGR heat exchange unit bias in above-mentioned technical scheme
The indexing means of cartridge module, also with some following beneficial effect：
1. the utility model utilizes the eccentric structure of eccentric interior cartridge module, realization is connected with its clamping；
2. indexing means body of the present utility model is concentric structure, make its processing and fabricating simple, be easy to and eccentric inner cylinder
The connection of component coordinates；
3. screw of the present utility model clamps eccentric interior cartridge module by transition support block, increase and eccentric interior cartridge module
Contact area, prevent from causing because clamping force is excessive eccentric interior cartridge module to deform or weigh wounded surface；
4. be sphere-contact between screw of the present utility model and transition support block, be easy to transition support block from homophony
Section, ensure the reliability clamped.
