The using method of the invention is as follows:

in the using process, the heat-conducting carrier compressed by the scroll compressor 2 enters the inside of the heat-conducting device 5 through the conduit 4, so that the gas content in the cavity of the inner cavity of the heat-conducting pipe 51 in fig. 5 and located on the right side of the pressure receiving plate 57 is increased, the pressure in the cavity is increased, the pressure receiving plate 57 is pushed to move in the leftward direction in fig. 5 until the pressure receiving plate 57 moves to the connection position of the heat-conducting device 5 and the flow-guiding channel 6, and thus the heat-conducting carrier enters another heat-conducting device 5 through the flow-guiding channel 6, and a part of the heat-conducting carrier can flow into the flow-limiting discharge pipe 8 from the flow-guiding channel 6 and discharge into the secondary discharge pipe 9 and flow into the main discharge pipe 7 in the process of passing through the flow-.

If scroll compressor 2 was in the state of low power this moment, the heat conduction carrier total amount that discharges from scroll compressor 2 delivery outlet and flow into to heat conduction device 5 inside is less, and the velocity of flow is slower, only can balance the volume of input of scroll compressor 2 through the discharge amount of single current-limiting calandria 8 this moment to make the heat conduction carrier this moment only flow through the heat conduction device 5 that is located the top.

If scroll compressor 2 is in the operating condition of high power this moment, it is great to flow into in addition to the inside heat conduction carrier total amount of heat conduction device 5 from 2 delivery outlets of scroll compressor, the velocity of flow is very fast, the discharge capacity of single current-limiting calandria 8 can't balance the discharge capacity of scroll compressor 2, thereby make subsequent heat conduction device 5 participate in the heat dissipation and increase the quantity of participating in the discharged current-limiting calandria 8, and then balance the discharge capacity of scroll compressor 2, thereby realized that the pipeline length that the heat conduction carrier flowed through is directly relevant with scroll compressor 2's power.
