It should be noted that, the present invention does not limit 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.

As a preferred embodiment, the drainage chamber 111 'and the guiding acceleration chamber 112' are both rectangular, and the spraying member 11 'is provided with a plurality of liquid inlet holes 115'; a plurality of sub-pipelines are respectively arranged at the tail end of the transfusion pipeline 10, each sub-pipeline is correspondingly connected with one liquid inlet hole 115 ', so that liquid can be simultaneously fed into the plurality of liquid inlet holes 115 ', the plurality of liquid inlet holes 115 ' are communicated with the drainage cavity 111 ', the water pressure in the drainage cavity 111 ' can be effectively improved through the arrangement mode, and the initial flowing speed of cooling liquid is effectively improved. 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 rectangular parallelepiped shape having a flat shape, and the width of the rectangular parallelepiped shape is set to six times the height, so that the cooling liquid can obtain a sufficiently large 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'.

Through data modeling and multiple tests for simulating fluid flow, the test result shows that the height of the drainage cavity 111 ' is set to be one third of the height of the guide acceleration cavity 112 ', so that cooling liquid flowing out of the drainage cavity 111 ' can be sprayed out through the spraying port 116 ' after being sufficiently accelerated in the guide acceleration cavity 112 ', and the spraying effect of the cooling liquid is effectively improved.

Referring next to fig. 7, a first guide accelerating structure 113 'is disposed on a side close to the drainage chamber 111', and a second guide accelerating structure 114 'is disposed on a side far from the drainage chamber 111'.

Specifically, the first guide acceleration structure 113 'includes a vertical section 1131' and an inclined section 1132 ', and referring to the orientation in fig. 7, the vertical section 1131' is formed extending upward along the bottom surface of the guide acceleration chamber 112 ', the inclined section 1132' is formed extending obliquely downward along the top of the vertical section 1131 'to a side (i.e., the right side) close to the second guide acceleration structure 114', and the vertical section 1131 'is connected to the bottom surface of the drainage chamber 111' by an arc-shaped structure, so as to effectively reduce the energy loss generated when the cooling liquid flows therethrough. 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 portion 1132 'extends to a position beyond the vertical extension line of the second guiding acceleration structure 114', so that the notch is formed below the inclined portion 1132 ', that is, the cooling liquid can only flow out through the notch after being squeezed by the right side wall of the second guiding acceleration structure 114' and the inner side wall of the guiding acceleration cavity 112 ', so as to further ensure the acceleration effect of the guiding acceleration cavity 112'.

The technical personnel in the field can understand that the technical personnel can set the specific structure of the diversion structure according to the actual use requirement, and only the diversion acceleration effect can be realized; such changes in the specific structure may be made without departing from the basic principles of the invention and are intended to be within the scope of the invention.

As shown in fig. 9, the spray member 11 "includes a main body 111" and a nozzle 1111 ", an injection port 1112" and a spray port 1113 "provided on the main body 111", and the main body 111 "is provided with a suction chamber 1114", a mixing chamber 1115 "and a diffusion chamber 1116" in this order along a flow direction of the cooling liquid (i.e., from top to bottom); wherein at least a portion of the nozzle 1111 "is disposed in the chamber 1114" such that cooling fluid entering through the nozzle 1111 "can be sprayed directly into the chamber 1114". A flow dividing member 16 is arranged upstream of the spray member 11 ", the liquid supply pipeline 10 is divided into three liquid supply branches by the flow dividing member 16, the three liquid supply branches are respectively connected with the nozzle 1111" and the injection port 1112 "arranged at both sides of the nozzle 1111" so as to supply the cooling liquid to the nozzle 1111 "and the injection port 1112", and the spray port 1113 "is arranged at the lower port of the main body 111", that is, at the end of the diffusion chamber 1116 "away from the mixing chamber 1115".

It can be understood by those skilled in the art that, although the spraying cooling system described in the preferred embodiment employs the flow dividing member 16 to realize flow dividing, this is not restrictive, and the cooling liquid can be directly introduced above the spraying member 11 "and then flow dividing can be realized through the nozzle 1111" and the injection port 1112 "by itself, and the present invention does not limit any specific type of the flow dividing member 16, and the skilled person can set itself according to the actual use requirement as long as the infusion pipeline 10 can realize flow dividing through the flow dividing member 16.

Further, the central axes of the nozzle 1111 ", the suction chamber 1114", the mixing chamber 1115 "and the diffusion chamber 1116" coincide so that the entire coolant passage within the spray member 11 "is vertical; the arrangement mode not only can better utilize gravitational potential energy to accelerate, but also can ensure that the general flow direction of the cooling liquid does not need to be changed too much, thereby effectively reducing energy loss and further effectively ensuring that the cooling liquid can be sprayed out at a higher speed.
