Both ends of the U-shaped tube 32 are communicated with the liquid medium circulation refrigeration module 31. A plurality of the U-shaped tubes 32 are symmetrically distributed about the axis of the resistor body 1. The inner and outer sides of the U-shaped tube 32 are respectively in contact with the surfaces of the resistor body 1 and the aluminum housing body 2. An air duct 8 is formed between adjacent two U-shaped tubes 32. The liquid medium circulation refrigeration module 31 is fixedly connected to the resistor mounting base plate 7;

[0035] Air vent grilles 21 provided at both ends of the aluminum housing body 2;

[0036] A heat dissipation fan module 5 arranged along the axis of the aluminum housing body 2 at one end of the resistor body 1;

[0037] The protective component 4 includes a protective plate 41, an elastic ring 42 and an elastic honeycomb plate 43. The elastic ring 42 runs through several protective plates 41. The protective plates 41 and the elastic ring 42 are both sleeved on the outside of the aluminum shell body 2. Both ends of the protective plate 41 are fixedly connected to the elastic honeycomb plate 43. The elastic honeycomb plate 43 is installed at the end of the aluminum shell body 2.

[0038] Furthermore, the heat dissipation system 3 also includes a cold medium circulation pipe 33, a hot medium circulation pipe 34, a hollow disk 35 and a hollow tube 36. The V-shaped tube 32 is fixedly connected between the two hollow disks 35. The hollow disk 35 and the hollow tube 36 are fixedly connected. The hollow disk 35 and the hollow tube 36 are sleeved on the surface of the end cap rod 11. The two hollow tubes 36 are connected to the liquid medium circulation refrigeration module 31 through the cold medium circulation pipe 33 and the hot medium circulation pipe 34 respectively.

[0039] Furthermore, the heat dissipation fan module 5 includes a driving part and a blade part, the blade part is movably sleeved on the surface of the hollow tube 36, the driving part is transmission-connected to the blade part, and the driving part is fixedly connected to the aluminum shell body 2.

[0040] Furthermore, both ends of the aluminum shell body 2 are fixedly connected with end cap tubes 22 , the end cap rod 11 and the hollow tube 36 are both sleeved in the end cap tube 22 , and the elastic honeycomb panel 43 is fixedly sleeved on the surface of the end cap tube 22 .

[0041] Furthermore, radial rods 411 are fixedly connected to both ends of the protection plate 41 , radial guide rails 431 are arranged on the surface of the elastic honeycomb plate 43 , and the radial rods 411 are embedded in the radial guide rails 431 .

[0042] Furthermore, a support frame 71 and a receiving chamber 72 are provided on the surface of the resistor mounting base plate 7 , the end cap tube 22 is fixedly connected to the support frame 71 , and the liquid medium circulation refrigeration module 31 is fixedly connected in the receiving chamber 72 .

[0043] In an embodiment of the present invention, the temperature sensor, the liquid medium circulation refrigeration module 31, and the radiator fan module 5 are all communicatively connected to the integrated processor module. The specific models and structures of the liquid medium circulation refrigeration module 31 and the radiator fan module 5 are not limited and will not be elaborated here. The elastic ring 42 is made of a stainless steel ring. Through holes 412 are provided on the surface of the protective plate 41, and the elastic ring 42 passes through the through holes 412. The elastic ring 42 is arranged and distributed along the axis of the aluminum shell body 2. The elastic honeycomb plate 43 is made of hard rubber, and the honeycomb holes on the surface of the elastic honeycomb plate 43 correspond to the positions of the air grille 21. The impact force received by the protective plate 41 is first weakened by the elastic deformation of the elastic ring 42. When the impact force is transmitted to the elastic honeycomb plate 43 through the radial rod 411 and the radial guide 431, the honeycomb-like structure on the surface of the elastic honeycomb plate 43 weakens the impact received by the protective plate 41 again through elastic deformation.

[0044] Please refer to Figure 7 , in an embodiment of the present invention, a water-absorbing member 6 is provided along the axis of the aluminum shell body 2 at the other end of the resistor body 1, and the water-absorbing member 6 is fixedly sleeved on the surface of the hollow tube 36.

[0045] Furthermore, the water-absorbing member 6 includes an annular mesh shell and water-absorbing cotton, and the inner and outer sides of the annular mesh shell are respectively in contact with the surface of the hollow tube 36 and the aluminum shell body 2.

[0046] In an embodiment of the present invention, the annular mesh shell is used to block particulate impurities in the air, and the water-absorbing cotton is used to absorb moisture in the air.

[0047] Working principle: When the temperature sensor monitors that the temperature inside the aluminum shell body 2 ≤ T1 °C, the integrated processor module controls the radiator fan module 5 to start. When the radiator fan module 5 starts, the outside air first enters the aluminum shell body 2 through the elastic honeycomb plate 43 and the air grille 21 at one end of the aluminum shell body 2, then passes through the water-absorbing member 6 for dust removal and water removal, then flows along the air duct 8 between several U-shaped tubes 32, and finally is discharged through the elastic honeycomb plate 43 and the air grille 21 at the other end of the aluminum shell body 2. Since the air ducts 8 are all distributed at the positions on the side and two end faces of the resistor body 1, the contact area between the air and the resistor body 1 can be maximally increased, and thus the resistor body 1 can be quickly cooled down;

[0048] When the temperature sensor monitors that the internal temperature of the aluminum shell body 2 is greater than T1°C, the integrated processor module simultaneously controls the heat dissipation fan module 5 and the liquid medium circulation refrigeration module 31 to start, and the liquid medium circulation refrigeration module 31 controls the cold medium to flow in the hollow tube 36, the hollow disk 35 and the V-shaped tube 32. On the one hand, since the V-shaped tube 32 is in contact with the side and two end faces of the resistor body 1 and the aluminum shell body 2 at the same time, it can directly absorb the temperature of the surface of the resistor body 1 and the aluminum shell body 2. On the other hand, since the air flows between several V-shaped tubes 32, the V-shaped tube 32 can also absorb the heat in the air, thereby achieving the purpose of rapid cooling to the maximum extent.

[0049] In addition to the functions of ventilation and blocking impurities in the air, the elastic honeycomb panel 43 also has the functions of ventilation and blocking impurities in the air. When the aluminum shell body 2 is impacted by the outside, the protective plate 41 is the first to bear the brunt of the impact. Therefore, the impact force received by the protective plate 41 is first directly weakened by the elastic deformation of the elastic ring 42. The impact force received by the protective plate 41 is transmitted to the elastic honeycomb panel 43 through the radial rod 411 and the radial guide rail 431. The honeycomb structure on the surface of the elastic honeycomb panel 43 further weakens the impact received by the protective plate 41 through elastic deformation, thereby greatly weakening the impact force directly received by the aluminum shell body 2, thereby preventing the U-shaped tube 32 and the resistor body 1 inside the aluminum shell body 2 from being damaged, and having the characteristics of good protection effect.

[0050] In summary, the present application utilizes a structural design in which the aluminum shell body 2, the heat dissipation system 3, the protective component 4 and the heat dissipation fan module 5 cooperate with each other. (1) When the outside air passes through the elastic honeycomb panel 43 and flows along the air duct 8 between the plurality of V-shaped tubes 32 on the outer surface of the resistor body 1, the liquid medium circulation refrigeration module 31 controls the flow of the cold medium in the plurality of V-shaped tubes 32. On the one hand, since the V-shaped tubes 32 are in contact with the side and two end faces of the resistor body 1 and the aluminum shell body 2 at the same time, the temperature of the surface of the resistor body 1 and the aluminum shell body 2 can be directly absorbed. On the other hand, since the air flows between the plurality of V-shaped tubes 32, the V-shaped tubes 32 can also absorb the heat in the air and have the characteristic of rapid cooling.

[0051] (2) In addition to the functions of ventilation and blocking impurities in the air, when the aluminum shell body 2 is impacted by the outside, the elastic ring 42 and the elastic honeycomb plate 43 can both be elastically deformed to weaken the impact force, thereby preventing the resistor body 1 from being damaged, and having the characteristic of good protection effect.
