Thermocouple cold end shell of reactor core detector assembly, compensation temperature equalizer and assembly

The utility model discloses a reactor core detector assembly thermocouple cold end shell, a compensation temperature equalizer and an assembly, the cold end shell comprises a shell body of a splicing structure, the shell body is of a columnar structure, and the side surface of a local position in the circumferential direction of the shell body is a cylindrical surface; the side faces of other positions fall in a space defined by the complete cylindrical surface, and the complete cylindrical surface is a complete cylindrical surface obtained by the axis and the radius corresponding to the cylindrical surface. By adopting the cold end shell provided by the scheme, the thermocouple cold end can be conveniently arranged in the detector assembly sleeve, so that the cold end is in a sleeve temperature environment with relatively stable temperature, and the compensation temperature equalizer and the thermocouple assembly are based on the thermocouple cold end shell. 本实用新型公开了一种堆芯探测器组件热电偶冷端壳体、补偿均温器及组件，所述冷端壳体包括为拼接式结构的壳
