Generally select for use heat pipe radiator that travelling wave tube is dispelled the heat on the communication satellite.Consider that travelling wave tube adopts the ring backup mode more, heat pipe radiator is mainly the orthogonal heat pipes radiator, with the work of evening up with the temperature between the travelling wave tube of not working.The orthogonal heat pipes radiator of using on the Communication in China satellite all is hybrid orthogonal heat pipes radiator at present, promptly the heat pipe of a direction is embedded in structural slab inside (adopting the heat pipe of this mounting means to be called pre-buried heat pipe), then is installed in corresponding structure plate outer surface (adopting the heat pipe of this mounting means to be called the outer heat pipe that pastes) with the heat pipe of pre-buried heat pipe axis normal.Typical travelling wave tube heat dissipating method is that travelling wave tube is installed in pre-buried heat pipe zone, evens up the temperature of travelling wave tube self by pre-buried heat pipe, and passes through the outer heat pipe that pastes with the uniform whole orthogonal heat pipes radiator zone of arriving of the hear rate of travelling wave tube.Though adopt this travelling wave tube heat dissipating method can avoid the travelling wave tube temperature too high, the temperature difference between the pre-buried heat pipe is bigger, especially to paste heat pipe quantity greatly and outward be not a lot of situations to the travelling wave tube hear rate.This causes the radiating efficiency of orthogonal heat pipes radiator low.The low orthogonal heat pipes radiator area that then requires of radiating efficiency is just big, and this can cause the increase of orthogonal heat pipes radiator weight.Then need to increase outer quantity of pasting heat pipe in order to improve radiating efficiency, this can cause the increase of orthogonal heat pipes radiator weight equally.Quite strict in view of communication satellite to the control of weight, do not allow sometimes to gain in weight.
Summary of the invention
The purpose of this utility model is to provide a kind of outer subsides heat pipe soaking formula travelling wave tube heat abstractor that can significantly improve the radiating efficiency of travelling wave tube under the prerequisite of not gaining in weight.
Realize the technical scheme of the utility model purpose: a kind of outer heat pipe soaking formula travelling wave tube heat abstractor that pastes, it comprises structural slab, be installed in the pre-buried heat pipe in the structural slab and be installed in I-shaped outer heat pipe and the travelling wave tube of pasting on the structural slab end face, pre-buried heat pipe is vertical mutually with the axis of outer subsides heat pipe, wherein, described travelling wave tube is directly installed on the outer heat pipe top of pasting.
Described travelling wave tube is connected by screw with the outer heat pipe that pastes, and screw is with stop sleeve outward, and the bottom surface of stop sleeve is positioned on the structural slab outer surface of cupular part, and the end face of stop sleeve is concordant with outer subsides heat pipe upper surface.
Described travelling wave tube and outer the subsides between the heat pipe are provided with heat filling.
Described heat filling can be heat-conducting silicone grease, heat conductive pad or silicon rubber.
Useful technique effect of the present utility model: the utility model directly is assigned to outer the subsides on the heat pipe to the travelling wave tube hear rate, utilize the outer isothermal that pastes heat pipe self to realize the uniform distribution of travelling wave tube hear rate on each pre-buried heat pipe, therefore can accomplish to make each pre-buried heat pipe temperature identical, thereby significantly improve the radiating efficiency of travelling wave tube.Travelling wave tube and the outer heat pipe that pastes are positioned at same structural slab zone, so can economize out more space on the structural slab, thereby more help the general layout design of instrument or allow to install more instrument and equipment.
