It should be noted that, since the structure of the refrigerant circulation system described in the present preferred embodiment is the same as that described in the first preferred embodiment, no further description is provided herein. As shown in fig. 5 to 7, a drainage cavity 111 'and a guiding acceleration cavity 112' are disposed on the spraying component 11 ', wherein the drainage cavity 111' is communicated with the infusion pipeline 10 through a liquid inlet hole 115 ', the guiding acceleration cavity 112' is provided with a spraying port 116 ', a first guiding acceleration structure 113' and a second guiding acceleration structure 114 'disposed at two sides of the spraying port 116', and a gap is disposed between the first guiding acceleration structure 113 'and the second guiding acceleration structure 114' for the cooling liquid to pass through in an accelerated manner; the first guiding acceleration structure 113 'and the second guiding acceleration structure 114' are jointly configured to accelerate the cooling liquid in the flow guiding cavity 111 'to spray to the surface of the condenser 20 through the spraying port 116'. It should be noted that, the present invention does not set any limitation on the specific structure of the guiding acceleration structure, as long as the guiding acceleration structure can perform the guiding acceleration function; for example, although the guiding acceleration structure described in the preferred embodiment includes the first guiding acceleration structure 113 ' and the second guiding acceleration structure 114 ', it is obvious that the guiding acceleration structure may also include only the first guiding acceleration structure 113 ', and the technician may set the structure according to the actual use requirement.

Of course, this arrangement is not restrictive, and the skilled person can set the specific shapes of the drainage chamber 111 'and the guiding acceleration chamber 112' according to the actual use requirement. Preferably, the drainage chamber 111 ' has a flat rectangular parallelepiped shape, and the width of the rectangular parallelepiped shape is set to be six times the height so that the coolant can obtain a sufficient initial velocity through the drainage chamber 111 ' to enter the guide acceleration chamber 112 '; it is further preferable that the bottom surface of the drainage chamber 111 'is configured to have a shape with a high inlet and a low outlet, so as to further increase the speed of the cooling liquid when it enters the guide acceleration chamber 112'.

Preferably, the inclined portion 1132 'is inclined obliquely downward by an angle of 30 ° so as to simultaneously take account of the flow velocity and the flow path, thereby effectively ensuring that the cooling liquid can be effectively accelerated through the inclined portion 1132'. The coolant flowing into the drainage cavity 111 'starts to go up along the left side wall of the vertical section 1131' after flowing through the arc-shaped structure, and then, under the dual action of kinetic energy and gravitational potential energy, the coolant starts to go down along the top wall of the inclined section 1132 ', and a large amount of coolant rushes into the vicinity of the gap, namely, the position close to the right side of the second guiding acceleration structure 114', and when rushing out of the gap, the flow velocity of the coolant is further improved.
Further, the right end of the inclined segment 1132 'extends beyond the vertical extension line of the second guiding acceleration structure 114', so that the gap is formed below the inclined segment 1132 ', that is, the cooling liquid may only flow out through the gap after being squeezed by the right side wall of the second guiding acceleration structure 114' and the inner side wall of the guiding acceleration chamber 112 ', so as to further ensure the acceleration effect of the guiding acceleration chamber 112'.
