[0032] like Figures 1-7 As shown, this utility model provides a chassis 100, including a shell 1, a slot frame assembly 2, an integrated circuit board assembly 3, and a heating device 4. The slot frame assembly 2 is connected to the shell 1 and has at least two slots 201. The integrated circuit board assembly 3 includes at least two circuit boards, each disposed in one slot 201. The heating device 4 is disposed within the shell 1 and can heat the integrated circuit board assembly 3. Heating the integrated circuit board assembly 3 by the heating device 4 allows it to operate normally even at low temperatures, increasing the applicability of the chassis 100. Each circuit board can be inserted into the slot 201 frame for easy assembly and disassembly from the slot frame assembly 2. Multiple circuit boards can be assembled into the slot frame assembly 2, and then the slot frame assembly 2 can be installed into the shell 1. Disassembly and assembly only require separating the slot frame assembly 2 and the shell 1, making it convenient and quick.

[0033] In this embodiment, the heating device 4 includes at least one heating body 401, each heating body 401 being disposed on the slot frame assembly 2.

Furthermore, when disassembling a circuit board, it is not necessary to disassemble the heating body 401; that is, the heating body 401 does not affect the assembly or disassembly of the circuit boards.

[0034] In this embodiment, the slot frame assembly 2 includes a first frame 202 and a second frame 203 disposed opposite to each other, both of which are connected to the housing 1; the first frame 202 is provided with at least two first grooves 204 on the side near the second frame 203, and the second frame 203 is provided with at least two second grooves 205 on the side near the first frame 202, the first grooves 204 and the second grooves 205 correspond one-to-one, and each first groove 204 can form a slot 201 with the corresponding second groove 205.

The top cover 102 and the base plate 101 are respectively connected to both ends of the side plate assembly. The base plate 101, the top cover 102, and the side plate assembly can form a closed inner cavity. Each heating body 401 is disposed within the closed inner cavity, which can reduce heat loss and reduce energy loss.

[0038] In this embodiment, a back plate 5, a first baffle 6, and a second baffle 7 are also included. The two ends of the back plate 5 are fixedly connected to the first side plate 103 and the third side plate 105, respectively. The slot frame assembly 2 is fixedly connected to the back plate 5.

Gaps are left between the first outer side wall and the first side plate 103, and gaps are left between the second outer side wall and the third side plate 105. The two ends of the first baffle 6 are... The first side plate 103 and the slot frame assembly 2 are fixedly connected, and the two ends of the second baffle 7 are fixedly connected to the third side plate 105 and the slot frame assembly 2, respectively. The first side plate 103, the back plate 5, the first outer wall, the first baffle 6, the bottom plate 101, and the top cover 102 can form a first enclosed space 8, and the third side plate 105, the back plate 5, the second outer wall, the second baffle 7, the bottom plate 101, and the top cover 102 can form a second enclosed space 9. At least one heating body 401 is provided in both the first enclosed space 8 and the second enclosed space 9. The first enclosed space 8 and the second enclosed space 9 are smaller than the enclosed inner cavity. The heating body 401 is located in the first enclosed space 8 and the second enclosed space 9, which can further reduce heat loss, enable rapid heating, and improve heating efficiency. This embodiment makes full use of the back plate 5, the shell 1, the first frame 202, and the second frame 203 to form the first enclosed space 8 and the second enclosed space 9, resulting in a compact structure.

[0039] In this embodiment, a first cover plate 10 and a second cover plate 11 are also included. The first cover plate 10 and the second cover plate 11 are both disposed on the side of the top cover 102 near the bottom plate 101. The first side plate 103, the back plate 5, the first outer side wall, the first baffle 6, the bottom plate 101 and the first cover plate 10 can form a first enclosed space 8. The third side plate 105, the back plate 5, the second outer side wall, the second baffle 7, the bottom plate 101 and the second cover plate 11 can form a second enclosed space 9.

The temperature control plate 402 is located in the first enclosed space 8 or the second enclosed space 9, resulting in a compact structure.

[0041] In this embodiment, the temperature control board 402 can control the heating elements 401 to turn on or off. The temperature detection interface on the temperature control board 402 receives signals from the temperature detection device, which senses the real-time temperature at its location and uploads it to the temperature control board 402. The temperature control board 402 can obtain the on / off status of the heating elements 401. The temperature control board 402 controls the heating elements 401 to turn on or off by controlling relays. When the temperature is below the start-up temperature of each board, the temperature control board 402 controls the relays to close, providing voltage to the heating elements 401, and the heating elements 401 start working. When the operating temperature of the board is reached, the control relays are opened, and the heating elements 401 stop heating.

[0042] In this embodiment, each heating element 401 is an electric heating tube, preferably with a power of 100W. The heating tube is fixed to the first frame 202 and the second frame 203 by fixing strips 12. The temperature detection device is a temperature sensor. The first frame 202, the second frame 203, the back plate 5, and the integrated board assembly 3 can be assembled into a slot 201 frame system.
