Please refer to Fig. 1-3, Fig. 1 be Section Bar Heat Sinks when being used alone heat radiation power with environment temperature change curve
Figure, Fig. 2 are that for heat radiation power with the change curve of environment temperature, Fig. 3 is fever when being used alone for room temperature heat pipe, Cryo Heat Tube
Module at different ambient temperatures needed for heat radiation power.
As described in the background section, in the prior art, the structure species of radiator are single, using there are limitation,
If the radiator of this single form (in such as outdoor environment, becomes in the biggish environment of temperature change from summer to winter temperature
Change larger) it is interior in use, the heat radiation power in certain temperature sections is lower, it is difficult to it satisfies the use demand.
By taking Section Bar Heat Sinks commonly used in the prior art and heat-pipe radiator as an example, heat dissipation of the embodiment of the present invention with regard to the two
Relationship between power and environment temperature is studied.
As shown in Figure 1, Section Bar Heat Sinks are primarily referred to as the mental sections radiator such as aluminium, copper, its advantage is that it is at low cost, and its
Heat-sinking capability will not fail at low ambient temperatures, especially within the scope of -15 DEG C or less of temperature, can still keep higher heat dissipation
Power.But the heat-sinking capability of Section Bar Heat Sinks can but be gradually decreased with the raising of temperature, in 30 DEG C or more of hot environment
In, heat-sinking capability is extremely low.Moreover, the thermal resistance of Section Bar Heat Sinks is big, when unit area heat flow density is larger, just can not
Meeting cooling requirements, further to increase its heat-sinking capability, the volume of required profile is larger, and is limited by installation space,
The volume of radiator tends not to excessive.
The advantages of heat-pipe radiator can be divided into room temperature heat pipe and Cryo Heat Tube again, both form radiators is the capacity of heat transmission
By force, thermal resistance is small, also can satisfy cooling requirements when unit area heat flow density is big, and therefore, heat radiation power can be made very
Greatly.But in heated tube radiator the physical characteristics such as cooling medium phase transformation influence, room temperature heat pipe and Cryo Heat Tube are in low temperature ring
When heat sinking function has failure under border, i.e. failpoint, as shown in Fig. 2, the failpoint of room temperature heat pipe is substantially at -15 DEG C, and
For the failpoint of Cryo Heat Tube substantially at -35 DEG C, this just significantly limits the use of the two at low ambient temperatures.Moreover, low temperature
The thermal resistance of heat pipe is larger compared with room temperature heat pipe, and under conditions of reaching same heat radiation power, the volume of Cryo Heat Tube compares room temperature again
Big more of heat pipe.
However, for the IGBT in high voltage control cabinet, (Insulated Gate Bipolar Transistor, that is, insulate
Grid bipolar junction transistor) for the high-power components such as module, rectifier bridge or diode (led) module, at work, it is necessary in time
The heat of generation is distributed, otherwise may will lead to the damage of high-power component, influences the normal operation of equipment.Such as figure
Shown in 3, when being applied to outdoor, the either hot environment in the low temperature environment in winter or summer, above-mentioned high-power component
Required heat radiation power is substantially consistent, and therefore, this just needs a kind of to all have higher dissipate in wide temperature range
