Description
Technical field
The present invention relates to aeronautical and space technology space heat conduction fields, and in particular to a kind of special-shaped heat conduction with installation fin
Rope.
Background technology
With the continuous improvement of spacecraft power, the requirement to heat dissipation is also accordingly promoted.Wherein component power consumption by
Cumulative big, radiating requirements increase, and the component that especially quality is small, calorific value is high, temperature ramp-up rate is fast, occurred frequently by designing
It penetrates rate coating and installation radiator can no longer meet its radiating requirements.
It is to realize the effective ways of big power consuming devices rapid cooling, but limited by heat conduction rope head construction to install heat conduction rope
System, heat conduction rope can be only installed at the planar section of radiating piece at present.For the device that is fitted without plane, (stator of such as motor is
It is round), then need the mounting bracket for installing heat conduction rope, plane provided using mounting bracket, realize heat conduction rope and radiating element it
Between be indirectly connected with, formed heat dissipation channel.It is this to design and directly compare heat conduction rope mounted on radiating piece, hence it is evident that increase two
Locate thermal resistance, i.e. itself thermal resistance of the thermal contact resistance between mounting bracket and radiating element and mounting bracket, heat conduction rope utilizes effect
Rate substantially reduces, so needing the cross-sectional area of increase heat conduction rope, increases the weight of heat conduction rope；Mounting bracket increasing is set simultaneously
Add weight of equipment, increases the launch cost of equipment.
Invention content
In order to solve the problems in the existing technology, the present invention provides a kind of special-shaped heat conduction with installation fin
Rope mainly solves component big, the component heating position knot that can not provide thermal resistance between Plane Installation or component and heat conduction rope
The irregular radiating requirements of structure realize that the component for certain specific structure designs heat conduction installation interface.
The technical proposal for solving the technical problem of the invention is as follows：
A kind of special-shaped heat conduction rope with installation fin, the heat conduction rope include：Wrap up head, the copper braid over braid of radiating element
With installation band；Head and the installation band of package radiating element are fixed in copper braid over braid both ends respectively；The installation band is mounted on
On low-temperature receiver.
The beneficial effects of the invention are as follows：
A) for rectangular heat dissipation device, the single-contact which designs previous heat conduction rope is promoted at least 4 faces and is contacted,
It overcomes using the heat dissipation of conventional thermal conductive rope the offside device temperature of installation heat conduction rope is high, entire device temperature is non-uniform asks
Topic, while the thermal resistance of device and heat conduction rope can be reduced to less than half of conventional thermal conductive rope；
B) for circular radiator part, for the feelings of heat conduction rope heat dissipation can be recycled by installing heat conduction rope mounting bracket additional
The channel of radiating element and radiating surface is directly established in condition, the invention, is reduced device to the thermal resistance of radiating surface, is conducive to quickly dissipate
Heat；
C) it does not need mounting bracket and alleviates product own wt, after the thermal resistance reduction of simultaneity factor, the section of heat conduction rope
The weight of the smaller that product can design, heat conduction rope is also reduced.Space product launching costs are high, which is realizing effectively
Launching costs can be greatly lowered while heat dissipation；
D) invention can be directed to the respective design of the shape progress head construction of radiating element connecting portion.
