[0042] The embodiment of the utility model in the first aspect is to provide a heat exchange system, as shown in Figure 3 The first flow channel 2, the liquid storage tank 3, the heat exchanger 4, the first liquid discharge assembly 5 and the second liquid discharge assembly 6;

[0044] The liquid storage tank 3 and the heat exchanger 4 are communicated with the first flow channel 2 and are located between liquid inlet section 21 and liquid outlet section 22.
[0045] As shown in Figure 1 And Figure 2 In the existing heat exchange system, only one outlet for discharging the first liquid, the liquid discharge speed is slow, and because the flow channel is usually bent and extended in actual use, a small amount of liquid remains in the pipeline during the liquid discharge process and cannot be completely discharged.
[0046] The heat exchange system provided by the above-mentioned embodiment, the liquid in the liquid storage tank 3 and the first flow channel 2 can not only be discharged through the liquid outlet 221, but also be discharged through the cooperation of the first liquid discharge assembly 5 and the second liquid discharge assembly 6, solving the problem of slow liquid discharge speed of the single liquid outlet in the prior art, and also effectively emptying the liquid in the pipeline in the first flow channel 2, improving the cleanliness of the pipeline and preventing the deterioration of a small amount of liquid that cannot be completely discharged in the pipeline.
[0047] The cooperating draining modes of the first draining assembly 5 and the second draining assembly 6 can be various, for example, the liquid in the storage tank 3 and the first flow channel 2 can be drained from the first draining assembly 5 and the second draining assembly 6 under the action of gravity, or one of the first draining assembly 5 and the second draining assembly 6 admits air, and the liquid in the storage tank 3 and the first flow channel 2 is drained from the other under the action of air pressure, or the liquid is drained from the first draining assembly 5 and / or the second draining assembly 6 under the double action of gravity and air pressure, which can be specifically described in the following embodiments according to different implementation manners:
[0048] In some embodiments, as shown in Figure 3 the first draining assembly 5 includes a first pipeline 51 and a first valve 52 arranged on the first pipeline 51, and the first pipeline 51 communicates with the liquid outlet section 22.
[0049] In use, the first valve 52 can be used to control the opening and closing of the first pipeline 51, and control whether the first pipeline 51 drains liquid.

[0052] When the first pipeline 51 is directly connected with the liquid outlet section 22, as shown in Figure 4 the liquid outlet section 22 has a first interval section 222, and the height of the first interval section 222 is lower than that of the remaining interval sections of the liquid outlet section 22. The first pipeline 51 can be directly connected with the first interval section 222, so that the liquid in the liquid outlet section 22 can be smoothly drained from the first pipeline 51 under the action of gravity. When the storage tank 3 is connected with the liquid outlet section 22, the liquid in the storage tank 3 can be drained from the first pipeline 51 under the action of gravity.
[0053] When the first pipeline 51 is indirectly connected with the liquid outlet section 22 through other pipelines, the heat exchange system further includes a draining pipeline 7, and the first pipeline 51 can be connected with the liquid outlet section 22 through the draining pipeline 7. The setting position of the draining pipeline 7 will be described first as follows:
[0054] As shown in Figure 3 when the storage tank 3 is arranged close to the liquid inlet section 21 relative to the heat exchanger 4, and the inlet of the storage tank 3 and the outlet of the storage tank 3 are both arranged low, the inlet of the draining pipeline 7 communicates with the liquid inlet section 21, the outlet of the draining pipeline 7 communicates with the liquid outlet section 22, and the draining pipeline 7 is provided with a third valve 8. After the third valve 8 is opened, the liquid in the storage tank 3 can enter the draining pipeline 7 through the inlet and be quickly drained, and after the liquid is completely drained, the third valve 8 is closed.
[0055] On the basis of the above embodiments, as shown in Figure 4 the first pipe 51 is connected with the drainage pipe 7 and is connected between the outlet of the drainage pipe 7 and the third valve 8.
[0056] As shown in Figure 5 when the liquid storage tank 3 is arranged close to the liquid inlet section 21 relative to the heat exchanger 4 and the arrangement position of the inlet of the liquid storage tank 3 is higher than the arrangement position of the outlet of the liquid storage tank 3, the inlet of the drainage pipe 7 is communicated with the liquid outlet 221 of the liquid storage tank 3, the outlet of the drainage pipe 7 is communicated with the liquid outlet section 22, and the drainage pipe 7 is provided with the third valve 8. After the third valve 8 is opened, the liquid in the liquid storage tank 3 can be quickly drained through the outlet into the drainage pipe 7, and after the liquid is drained, the third valve 8 is closed.
[0057] On the basis of the above embodiments, the first pipe 51 is connected with the drainage pipe 7 and is connected between the outlet of the drainage pipe 7 and the third valve 8, and when it is necessary to drain the liquid in the first flow channel 2, the third valve 8 can also be closed or opened.

The first pipe 51 can be connected with the interval section between the outlet of the heat exchanger 4 and the outlet of the drainage pipe 7, or can be connected with the interval section between the outlet of the drainage pipe 7 and the liquid outlet 221, and the first pipe 51 can be selected to be connected with one of the two interval sections according to the arrangement height of the two interval sections. For example, when the interval section between the outlet of the heat exchanger 4 and the outlet of the drainage pipe 7 is relatively low, as shown in Figure 3 the first pipe 51 is connected with the interval section; and when the interval section between the outlet of the drainage pipe 7 and the liquid outlet 221 is relatively low, as shown in Figure 5 the first pipe 51 is connected with the interval section.
[0059] Of course, the liquid outlet 221 can also have a tee pipe, and the first pipe 51 is connected with the liquid outlet section 22 through the tee pipe.

[0062] Specifically, the second valve 62 can be a manually controlled valve or an electrically controlled valve.

When the liquid storage tank 3 is connected with the liquid inlet section 21, the liquid in the liquid storage tank 3 can be discharged from the second conduit 61 under the action of gravity.
[0065] For example, as shown in Figure 3 , the inlet of the forced discharge conduit 7 is in communication with the liquid inlet section 21, the outlet of the forced discharge conduit 7 is in communication with the liquid outlet section 22, and the second conduit 61 is connected with the interval section between the inlet of the forced discharge conduit 7 and the liquid inlet 211, which has a lower height.
[0066] Of course, the liquid inlet 211 can also have a tee joint, and the second conduit 61 is connected with the liquid inlet section 21 through the tee joint.

[0068] When it is necessary to discharge the liquid in the first flow channel 2, the third valve 8 can be closed or opened. In the closed state, the liquid in the first flow channel 2 can be discharged through the first conduit 51 and the second conduit 61 in two ways, respectively. In the opened state, the first conduit 51 and the second conduit 61 are in communication through the forced discharge conduit 7, and the liquid in the first flow channel 2 can be discharged under the action of gravity by selecting the first conduit 51 or the second conduit 61 with smaller resistance as the main conduit and the other as the auxiliary conduit.
[0069] As shown in Figure 6 and Figure 7 , in other embodiments, the second conduit 61 is not used for discharging liquid, but for air intake.
