Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 and 2, the present invention provides a memory core box with a box-in-box structure, including: the core box comprises a core box body 1, a plurality of box-in-box 3 sequentially nested in the core box body 1, and a storage cavity 2 arranged in the core box body 1. The storage chamber 2 is arranged inside the innermost cassette 3. The core box main body 1 and the box-in-box 3 are respectively filled with phase-change liquid. The storage cavity 2 is internally provided with a PCB which is connected with a transmission line, and the PCB is connected with a main system of the memory through the transmission line, so that data transmission is carried out.

Through set up one deck or multilayer box 3 in the core box main part 1 to set up storage cavity 2 in the box of inlayer the inside of box 3, so that when the box 3 intussuseption phase change liquid in the box, can realize the complete parcel to storage cavity 2 with comparatively a small amount of phase change liquid, thereby provide comprehensive protection and cooling function for the PCB board in the storage cavity 2. Moreover, even if the phase-change liquid in the box 3 in the box is more, the phase-change liquid can overflow into the box 3 in the outer layer box or the core box main body 1, so that the influence on external components can be avoided, and the safety of the whole system can be guaranteed.

The core box main body 1 and the in-box 3 are respectively provided with a plurality of liquid injection holes 11 so as to conveniently inject phase-change liquid into the in-box 3 and the core box main body 1, and thus, the PCB in the storage cavity 2 is protected.
