Problems solved by technology

[0002] In the cabinet layout of the automation instrument and control system, each chassis is stacked and installed one above the other. The size of the heat dissipation interval is relatively limited; at the same time, the heat output of different chassis is often inconsistent, and there are also differentiated requirements for forced air cooling or natural convection heat dissipation; currently there is no rack-mounted fan that is small in size, flexible in configuration, and has wide applicability

Embodiment

[0053] This embodiment proposes a combined modular 1U heat sink.

[0054] like Figure 1-2 As shown in the figure, the heat dissipation device of this embodiment is mainly composed of a guide frame 1, a vertical ventilation module 2 and a horizontal ventilation module 3; Flexible assembly required

[0055] The guide frame 1 of this embodiment is as follows image 3 As shown, it is composed of an installation frame 101 and a guide plate 102, wherein the installation frame 101 has a mounting hole 103, which is the overall external installation interface of the guide frame 1; The hole array 105 and the front ventilation hole array 106 allow cold air to enter from the left, right and front of the guide frame 1 , increase the area of ​​the air inlet, and improve the ventilation efficiency of the guide frame 1 .

[0056] The mounting frame 101 of this embodiment is formed by cutting a metal sheet and then bending and welding. It is the overall frame of the fan box. The deflector 10...

Abstract

The invention discloses a combined modular 1U heat dissipation device. The heat dissipation device of the invention comprises a guide frame, a vertical ventilation module and a horizontal ventilation module; the vertical ventilation module and the horizontal ventilation module are both installed in the guide The air guide frame is used to realize the natural reverse flow heat dissipation between the upper and lower chassis; the vertical ventilation module is used to realize the forced air cooling and heat dissipation in the vertical direction; the horizontal ventilation module is used to realize the forced air cooling in the horizontal direction. Heat dissipation; the vertical ventilation module and the horizontal ventilation module both use independent control units, and by controlling the working modes of the vertical ventilation module and the horizontal ventilation mode, various heat dissipation methods can be realized. The invention adopts a combined modular design, which can realize natural diversion heat dissipation or forced air cooling heat dissipation between the upper and lower chassis in a 1U height installation space, and the forced ventilation volume can be adjusted as required.

Description

technical field [0001] The invention belongs to the technical field of nuclear power instrumentation and control, and in particular relates to a combined modular 1U heat dissipation device. Background technique [0002] In the cabinet layout of the automated instrumentation and control system, each chassis is stacked up and down, and the diversion and heat dissipation channels should be reasonably designed to avoid the hot air of the lower chassis affecting the upper chassis; for cabinets with a large number of layout points, the available space between the chassis The size of the cooling interval is relatively limited; at the same time, the heat generation of different chassis is often inconsistent, and there are also differentiated requirements for forced air cooling or natural convection cooling; there is currently no small size, flexible configuration and wide applicability of rack-mounted fans . SUMMARY OF THE INVENTION [0003] The present invention provides a combi...
