Power selection appropriate length heat sink 111.
As an embodiment of the present embodiment, the upper surface of heat sink 111 is higher by the upper surface 0-1.5mm of upper cover plate 11.
Generally, the upper surface of heat sink 111 is concordant with the upper surface of upper cover plate 11 can be such that DC-DC devices are connect completely with heat sink
Touch, you can meet the cooling demand of DC-DC device agings test.In practical engineering application, it is contemplated that the bottom surface of DC-DC devices or
It is edge it is possible that the situation of out-of-flatness, and heat sink upper surface and upper cover plate top surface are completely concordant for test bench
The higher situation of manufacturing requirements, for the burn-in test of the various DC-DC devices suitable for engineering, radiating in the present embodiment
The upper surface of plate is preferably higher by the upper surface 0.5-1.5mm of upper cover plate, to ensure that each DC-DC devices and heat sink can be very
It is bonded well, caused heat distributes in quickening test.
The one side of upper cover plate 11 is provided with U-shaped mouth 113, and the U-shaped place side of mouth 113 is perpendicular to two groups of pins 112；Pedestal 12 corresponds to
A buckle 122 is provided with U-shaped mouth 113, DC-DC devices are placed on heat sink 111, rotary buckle 122, DC-DC devices consolidated
Due on heat sink 111, and then ensure that the positions of DC-DC devices during data acquisition is changeless, is prevented because position
Change reduce measurement data accuracy.
Upper cover plate 111 offers mounting hole 125 with the surrounding of pedestal 12, and the two is bolted connected.
As shown in Fig. 3, Fig. 4 and Fig. 5, the thickness of heat sink 111 is more than the thickness of upper cover plate 11.The thickness of heat sink 111
Increase, caused heat distributes during being advantageous to accelerate DC-DC device detections.
As shown in fig. 6, pedestal 12 is the hollow cavity that top offers fixing hole 2111；The internal diameter of fixing hole 2111 is equal to
The external diameter of heat sink 111, the lower shoe 123 of pedestal 12 offer heat emission hole 1231, are easy to dissipating for the bottom heat of heat sink 111
Hair, prevents the aggregation of heat.
The bottom surface of heat sink 111 passes upper cover plate 11 and stretched into fixing hole 2111, can increase the fixation of heat sink 111
Fastness, and can make heat promptly be shed from heat emission hole 1231.Preferably, heat sink 111 stretches into the depth of fixing hole 2111
Equal to the thickness of the top plate 121 of pedestal 12.
In the present embodiment, the side plate of top plate 121 and pedestal 12 is detachably connected, and the inside sidewalls of pedestal 12, which are provided with, fixes
Platform, top plate 121 are placed on fixed station, and the one end of top plate 121 away from buckle 122 offers two mounting grooves 1241, two installations
Groove 1241 is connected by a spring 124 or other elastic elements with the side wall of pedestal 12 respectively.When buckle 122 is opened, buckle 122
Being rotated along rotating shaft, its driven end pusher top plate 121 moves, so that top plate 121 moves towards the direction of spring 124, bullet
Spring 124 compresses.
In actual use, the one end of top plate 121 away from buckle 122 can also offer one or multiple mounting grooves
1241, mounting groove 1241 is connected by spring 124 or other elastic elements.
In addition, the material of heat sink 111 is copper, ceramics, aluminium, mica or aluminium alloy.
The thermal conductivity of copper is good, but expensive, and weight is larger.
Fine aluminium thermal conductivity is preferable, causes softer, and aluminium alloy that the present embodiment uses provides enough hardness, and aluminium alloy
Cheap, in light weight, thermal conductivity is poorer than copper.
The present embodiment can also combine two kinds of heat sink materials of copper and aluminium, that is, the chief of two kinds of heat sink materials be taken, in aluminium alloy
The embedding copper coin in bottom of heat sink 111.
Ceramics typically have high fusing point (mostly more than 2000 DEG C), and have fabulous chemical stability at high temperature
With good thermal conductivity.
Mica possesses good heat conductivity and barotolerance.
