In the refrigeration and heating circulation, the capillary tube plays a throttling role, can be combined with absorbed heat through increasing the tube diameter, equivalently realizes the throttling expansion effect of a system refrigerant, so that a one-way valve is not needed to control the heat dissipation of the refrigeration and heating working condition on a condensation section of the heat pipe, the production cost is reduced, the capillary tube branch pipe absorbs the heat dissipation of the heat pipe, and the cooperative debugging of the working condition of the system is easier because of the branch of the fork shape instead of a parallel passage, meanwhile, the heat pipe does not need to be driven by electric power, and the self-circulation of the density difference of the refrigerant can be realized.
