Detailed Description

A fixing structure 100 for a power tube according to an embodiment of the first aspect of the present utility model is described below with reference to fig. 1 to 9.

As shown in fig. 1 to 9, a fixing structure 100 for a power tube according to an embodiment of the first aspect of the present utility model includes a housing 1, a cover 2, and a spring plate 3.

Specifically, a housing groove 131 is formed on one side in the thickness direction (for example, the up-down direction in fig. 1) of the housing 1, and at least one first projection 12 is provided on the other side in the thickness direction of the housing 1, and the first projection 12 is adapted to abut against the power tube. The cover 2 is fastened to the housing 1, and the spring plate 3 is disposed in the accommodating groove 131. The spring 3 includes a first arc segment 31 and two second arc segments 32, the two second arc segments 32 are respectively connected at two ends of the length direction (e.g., left-right direction in fig. 1) of the first arc segment 31, the first arc segment 31 protrudes toward the direction of the cover 2, the first arc segment 31 is spaced apart from the bottom wall of the accommodating groove 131, the second arc segment 32 protrudes toward the direction of the housing 1, the second arc segment 32 contacts with the bottom wall of the accommodating groove 131, and the fastener 4 passes through the cover 2, the spring 3 and the housing 1 to be connected with the radiator.

For example, in the examples of fig. 1 to 5, the cover 2 is covered on the housing 1 along the thickness direction of the housing 1, and the elastic sheet 3 located in the accommodating groove 131 is limited, so as to clamp the elastic sheet 3 between the housing 1 and the cover 2, and ensure the installation stability of the elastic sheet 3, so that the elastic sheet 3 cannot be separated from the accommodating groove 131 in the process of deformation or recovery deformation. During installation, the power tube can be contacted with the radiator, then the whole of the shell 1, the elastic sheet 3 and the cover body 2 is placed on the power tube, the first bulge 12 of the shell 1 is abutted with the power tube, finally the fastener 4 such as a bolt penetrates through the cover body 2, the elastic sheet 3 and the shell 1 to be connected with the radiator, at the moment, the first bulge 12 can tightly press the power tube on the radiator, and the first bulge 12 effectively limits the power tube, so that the position of the power tube on the radiator is fixed. Therefore, the power tube can be firmly fixed on the radiator, so that the power tube and the radiator can exchange heat, heat dissipation of the power tube is realized, and meanwhile, the shell 1 and the cover body 2 can serve as insulating pieces to separate the elastic sheet 3 from the power tube, so that the insulating safety rule is met between the elastic sheet 3 and the power tube.

Referring to fig. 4-5, the first arc-shaped section 31 of the elastic sheet 3 protrudes upward, so that the first arc-shaped section 31 is spaced from the bottom wall of the accommodating groove 131, and a sufficient deformation space is provided for deformation of the elastic sheet 3 in the thickness direction of the housing 1, so that the pressing of the cover body 2 during deformation of the first arc-shaped section 31 is avoided. The two second arc sections 32 are protruded downwards, so that the second arc sections 32 are spaced from the inner wall of the cover body 2, one side, protruding towards the direction of the shell body 1, of the second arc sections 32 is contacted with the bottom wall of the containing groove 131, supporting force is provided for deformation of the elastic sheet 3, deformation space is formed between the bottom wall of the containing groove 131 and one side, towards the shell body 1, of the cover body 2, and deformation space is provided for deformation and recovery deformation of the second arc sections 32. Thereby, the elastic piece 3 can be deformed in the accommodating groove 131. Wherein, the length of second arc section 32 is less than first arc section 31, and when shell fragment 3 takes place deformation, the deformation volume mainly concentrates on first arc section 31, and first arc section 31 produces along casing 1 thickness direction and length direction's deformation volume promptly. Therefore, when the fixing structure 100 is used, the elastic sheet 3 can effectively compensate the deformation of the cover body 2 and the shell body 1 which cannot be recovered due to creep through deformation, so that the phenomenon that the shell body 1 or the cover body 2 is cracked can be avoided, and the service life of the fixing structure 100 is prolonged.

The fastening member 4 may vertically penetrate through the cover 2, the spring plate 3, and the housing 1 to be connected with the heat sink, and the fastening member 4 is used to fix the fixing structure 100 on the heat sink. Simultaneously, fastener 4 passes lid 2, shell fragment 3 and casing 1 along the thickness direction of casing 1, can effectively guide and restrict lid 2, shell fragment 3 and casing 1 along the elastic deformation and the recovery deformation that the thickness direction of casing 1 took place, avoids lid 2, shell fragment 3 and casing 1 to take place irregular elastic deformation and recovery deformation and damage fixed knot construct 100.

According to the fixing structure 100 for a power tube of the embodiment of the utility model, the cover body 2 and the shell 1 are buckled to define the accommodating space, the elastic sheet 3 with a plurality of arc segments is arranged in the accommodating space, and the accommodating space provides a deformation space for deformation of the elastic sheet 3. Therefore, deformation of the elastic sheet 3 can effectively compensate deformation of the cover body 2 and the shell body 1 which cannot be recovered due to creep, the power tube is pressed on the radiator, the pressure applied to the power tube by the fixing structure 100 can be prevented from being attenuated and invalid, and the cracking phenomenon of the fixing structure 100 can be avoided.

According to some embodiments of the present utility model, referring to fig. 1 and 3, the bottom wall of the receiving groove 131 has a concave portion 132, the concave portion 132 is concave in a direction away from the cover 2, the second arc-shaped section 32 is located in the concave portion 132, and the concave portion 132 is opposite to the first protrusion 12. So set up, shell fragment 3 can take place to support with the diapire of holding tank 131 at elastic deformation and resume deformation's in-process to transmit elasticity for casing 1, because recess 132 is relative with first arch 12, on the power tube is transmitted with the power by first arch 12 again, thereby indirectly compress tightly the power tube at the radiator, recess 132 can restrict the movement of shell fragment 3 along the length direction of casing 1 simultaneously. In addition, since the second arc-shaped section 32 is opposite to the first protrusion 12, the force of the second arc-shaped section 32 acting on the concave portion 132 can be transferred to the first protrusion 12 as much as possible, so that the power tube at the first protrusion 12 is pressed with larger force, and the fixation is more stable.

Referring to fig. 1, there are two first protrusions 12, two first protrusions 12 are respectively located at both ends of the housing 1 in the length direction, and each first protrusion 12 has a trapezoid shape, and each first protrusion 12 may be formed by protruding a bottom wall of a part of the accommodating groove 131 in a direction away from the dome 3. Wherein, the cross-sectional area of the end of the first protrusion 12 adjacent to the shrapnel 3 is larger, and the cross-sectional area of the end of the first protrusion 12 far away from the shrapnel 3 is smaller. Therefore, the end with larger cross-sectional area of the first protrusion 12 can receive the acting force of the second arc-shaped section 32 as much as possible, so that the acting force can be concentrated at the end with smaller cross-sectional area of the first protrusion 12, larger pressing force is applied to the power tube, and meanwhile, the material consumption of the shell 1 can be reduced, and the cost is reduced.

Wherein the second protrusion 13 is located at a side of the first body 11 facing the cover 2, and the third protrusion 22 is located at a side of the second body 21 facing the housing 1. When the cover body 2 and the housing 1 are connected, the second protrusion 13 is placed in the accommodating cavity 221 of the third protrusion 22 to achieve preset positioning, and then the second protrusion 13 and the third protrusion 22 can be mutually limited to limit the movement of the cover body 2 and the housing 1 along the length direction of the cover body and the housing by matching the buckle 16 with the clamping groove 211.

According to some embodiments of the present utility model, the height of the fourth protrusion 14 is smaller than the height of the fifth protrusion 23 in the thickness direction of the dome 3.
