Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic cooling, in particular to a vortex cooling mechanism applied to ultrasonic waves. Background Technique

[0002] When an ultrasonic fatigue machine conducts fatigue tests on specimens, the existing ultrasonic fatigue testing machines can only carry out ultra-high cycle fatigue tests at room temperature and cannot meet the experimental requirements under high-temperature conditions. The high-temperature environment will cause softening of the base material of the specimen material, resulting in a decrease in the material's ability to resist deformation, thereby affecting the accuracy of fatigue test data. Therefore, it is necessary to propose a vortex cooling mechanism applied to ultrasonic waves. Content of the Utility Model

[0003] The purpose of the utility model is to solve the above problems and propose a vortex cooling mechanism applied to ultrasonic waves.

[0004] To achieve the above purpose, the utility model provides the following technical solution: It is characterized by including a housing, an impeller assembly installed on the housing to facilitate the passage of ultrasonic specimens. The impeller assembly includes a bearing installed on the housing, an impeller installed on the bearing, several blades obliquely arranged on the impeller, and at least one air inlet hole installed on the housing that can blow the blades to rotate.

[0005] Preferably, several air outlet holes with a vortex effect are provided on the impeller.

[0006] Preferably, the air outlet holes are obliquely arranged.

[0007] Preferably, a positioning rod is also installed on the housing.

[0008] The beneficial effect of the utility model: Through the setting of this cooling mechanism, air is introduced from the air inlet hole to drive the impeller to rotate rapidly, and a vortex air flow is formed from the air outlet holes, thereby quickly cooling the position of the specimen test point, avoiding the influence of high temperature on the specimen material, and further improving the accuracy of the fatigue test data of the specimen;

[0009] Through the setting of the air outlet holes, the air outlet holes are arranged at a certain inclination angle, so that the air flow forms a vortex effect around the specimen after flowing out of the air outlet holes, thereby achieving the effect of quickly cooling the specimen.

[0013] Next, we will further explain a vortex cooling mechanism applied to ultrasonic waves according to the present utility model through embodiments in combination with the accompanying drawings.

[0014] It should be noted that all directional indications such as up, down, left, right, front, back... in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture as shown in the accompanying drawings. If this specific posture changes, the directional indications will also change accordingly.

[0015] In the present invention, unless otherwise clearly specified and limited, terms such as "connection" and "fixation" should be understood in a broad sense.

[0016] For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0017] Refer to Figures 1 to 2 As shown, the present utility model provides a vortex cooling mechanism applied to ultrasonic waves, which is characterized by including a housing 1 and an impeller assembly installed on the housing 1 to facilitate the passage of ultrasonic test pieces. The impeller assembly includes a bearing 20 installed on the housing 1, an impeller 21 installed on the bearing 20, several blades 22 arranged obliquely on the impeller 21, and at least one air inlet hole 23 installed on the housing 1 that can blow the blades 22 to rotate. Several air outlet holes 24 with a vortex effect are provided on the impeller 21. The air outlet holes 24 are arranged obliquely. A positioning rod 25 is also installed on the housing 1. Through the setting of this cooling mechanism, air is introduced through the air inlet hole 23 to drive the impeller 21 to rotate rapidly, and a vortex air flow is formed from the air outlet holes 24, thereby quickly cooling the position of the test point of the test piece, avoiding the influence of high temperature on the test piece material, and further improving the accuracy of the fatigue test data of the test piece. Through the setting of the air outlet holes 24, the air outlet holes 24 are arranged at a certain inclination angle, so that the air flow forms a vortex effect around the test piece after flowing out of the air outlet holes 24, thereby achieving the effect of quickly cooling the test piece.

[0018] When the utility model is in use, first, the housing 1 is installed on the fatigue testing machine through the positioning rod 25, so that the impeller 21 is located above the test piece. An air compressor is connected to the air inlet hole 23. When the fatigue testing machine works, gas is introduced through the air inlet hole 23. The gas blows the blades 22 to rotate, thereby driving the impeller 21 to rotate rapidly. During the rotation of the impeller 21, the air flow flows out from the air outlet hole 24 and forms a vortex around the test piece below the impeller 21, so as to cool the test piece and eliminate the influence of high temperature on the fatigue test of the test piece, and improve the detection accuracy of the fatigue testing machine.

[0019] The above embodiments are illustrative of the present utility model, rather than limiting the present utility model. Any solution obtained by simply changing the present utility model falls within the protection scope of the present utility model.
