Description

Technical Field

[0001] The utility model relates to the technical field of die castings, in particular to an aluminum die casting with high thermal conductivity. Background Art

[0002] Die casting is a kind of pressure casting parts, which is produced by using a pressure casting mechanical die casting machine equipped with a casting mold. The existing aluminum alloy die castings of motor housings are far from enough to dissipate heat simply through the heat dissipation performance of the aluminum alloy itself. The heat still remains inside the motor housing, resulting in poor heat dissipation.

[0003] There are also some technical solutions for aluminum alloy die-castings in the prior art, such as a Chinese patent with patent number 2019223705698. The invention proposes an aluminum alloy die-casting for a motor housing. The utility model relates to the technical field of die-castings. The aluminum alloy die-casting for a motor housing comprises: a motor housing, three equidistantly arranged heat dissipation grooves are opened on the left and right sides of the surface of the motor housing, and each heat dissipation groove is communicated with the inside of the motor housing, a heat dissipation net is embedded in the bottom of the inner wall of the heat dissipation groove, and a slot communicating with the inside of the motor housing is opened on one side of the inner wall of the heat dissipation groove, a pull plate is movably inserted in the slot, and a pull block is fixed in the middle of the first end of the upper surface of the pull plate, and a patch is attached to the end of the pull plate away from the slot; a disc is fixed at the rear end of the motor housing, and a circular hole is opened in the center of the back of the disc, an elastic shaft and an arc-shaped gasket are arranged in the circular hole, and two arc-shaped gaskets are provided and arranged symmetrically up and down: the beneficial effects of the utility model are: improving the heat dissipation effect of the motor housing and reducing the phenomenon of damage to the screw surface.

[0004] However, when the heat sink slot needs to be opened or closed, the housing in the above technology needs to pull the pull plate inside the slot one by one to control the opening and closing of the heat sink slot, which is not fast and efficient enough. At the same time, it is also more laborious to pull the pull plate out of the slot, so that the housing is not convenient and fast enough when used. Utility Model Content

[0005] The purpose of the utility model is to provide an aluminum die casting with high thermal conductivity to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high thermal conductivity aluminum die casting, comprising a shell, an annular groove is provided at the upper end of the shell, and a threaded groove is provided at the bottom of the shell corresponding to the annular groove, an annular baffle is provided in the annular groove, a thread is provided at the bottom of the annular baffle, and the thread is threadedly connected to the threaded groove, and cooling fins arranged in a circular array with the center of a circle as the center are fixedly connected to the outside of the shell, and a cooling groove is opened between the shells corresponding to adjacent cooling fins.

[0007] Preferably, a sealing shell is fixedly connected to the outer side of the shell, and the heat dissipation fins are all connected through the sealing shell.

[0008] Preferably, a water inlet cover is hingedly connected to the upper end of the sealing shell via a first hinge.

[0009] Preferably, a water outlet cover is hingedly connected to the lower end of the sealing shell via a second hinge.

[0010] Preferably, one end of the sealing shell is fixedly connected to a support seat.

[0011] The heat dissipation fins on the outside of the shell can be used to cool the shell, and the end of the heat dissipation fins away from the shell extends into the sealed shell, which can effectively dissipate heat for the heat dissipation fins and further reduce the temperature of the shell. After use, the annular baffle is separated from the shell, and the interior of the shell can be ventilated and heat dissipated through a number of heat dissipation grooves, thereby accelerating the transfer and dissipation of heat inside the shell. When the shell does not need to dissipate heat, the annular baffle is threadedly connected to the shell, so that the annular baffle can seal the heat dissipation groove to prevent external dust and impurities from entering the shell from the heat dissipation groove, which is also convenient for next use, so that the heat dissipation groove on the shell can be closed and opened at the same time. At the same time, the operation is simple, and there is no need to open and close the heat dissipation groove on the shell in a time-consuming and laborious manner, thereby making the shell more convenient and quick to use.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-6 The utility model provides a technical solution: a high thermal conductivity aluminum die casting, including a shell 1, an annular groove 2 is provided on the upper end of the shell 1, and a thread groove 3 is provided at the bottom of the shell 1 corresponding to the annular groove 2, an annular baffle 4 is provided in the annular groove 2, a thread 5 is provided at the bottom of the annular baffle 4, and the thread 5 is threadedly connected to the thread groove 3, and a heat dissipation fin 6 arranged in a circular array with the center of a circle as the center is fixedly connected to the outer side of the shell 1, and a heat dissipation groove 7 is opened between adjacent heat dissipation fins 6 corresponding to the shell 1.

[0021] Furthermore, a sealing shell 8 is fixedly connected to the outside of the shell 1, and the heat dissipation fins 6 are connected through the sealing shell 8. The heat dissipation fins 6 can effectively absorb the heat inside the shell 1. By injecting coolant into the sealing shell 8, the heat dissipation fins 6 can be effectively dissipated, and the temperature of the shell 1 can be further reduced.

[0022] Furthermore, a water inlet cover 10 is hingedly connected to the upper end of the sealing shell 8 through a first hinge 9 , and before casting, coolant can be injected into the sealing shell 8 through the water inlet cover 10 .

[0023] Furthermore, a water outlet cover 12 is hingedly connected to the lower end of the sealing shell 8 through a second hinge 11 . After the casting is completed, the coolant inside the sealing shell 8 can be discharged through the water outlet cover 12 .

[0024] Furthermore, one end of the sealing shell 8 is fixedly connected to a support seat 13, and the support seat 13 can effectively facilitate the stability of the casting during operation.

[0025] Specifically, when using the utility model, firstly, the annular baffle plate 4 is threadedly connected with the thread groove 3 at the bottom of the annular groove 2 on the shell body 1 through the thread 5 at the lower end, so that the annular baffle plate 4 closes the heat dissipation groove 7 on the shell body 1, and then the water inlet cover 10 is opened through the first hinge 9 to inject coolant. At this time, the heat dissipation fins 6 outside the shell body 1 can cool the shell body 1, and the end of the heat dissipation fins 6 away from the shell body 1 extends into the sealing shell 8, which can effectively dissipate heat for the heat dissipation fins 6 and further reduce the temperature of the shell body 1. After use, the annular baffle plate 4 is separated from the shell body 1, so that the inside of the shell body 1 can be ventilated and heat dissipated through a plurality of heat dissipation grooves 7, thereby accelerating the transfer and loss of heat inside the shell body 1. When the shell body 1 does not need to dissipate heat, the annular baffle plate 4 is threadedly connected to the shell body 1, so that the annular baffle plate 4 can block the heat dissipation groove 7 to prevent external dust and impurities from entering the shell body 1 from the heat dissipation groove 7, which is also convenient for next use.
