[0028] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0029] Example 1: See Figures 1 to 5 As shown, an oil chamber cooler comprises a cooler body 1, wherein at least three mutually parallel medium flow channels 2 are arranged in the cooler body 1, and the plurality of medium flow channels 2 are arranged at intervals from front to rear, and the two ends of the medium flow channels 2 are respectively connected to the left end face and the right end face of the cooler body 1;

[0030] A front connecting hole 3 is provided on the front side surface of the left end of the cooler body 1, and the front connecting hole 3 penetrates through the plurality of medium flow channels 2, and the rear end of the front connecting hole 3 is not connected to the last medium flow channel 2;

[0031] A rear connecting hole 4 is provided on the rear side surface of the right end of the cooler body 1, and the rear connecting hole 4 penetrates through the plurality of medium flow channels 2, and the front end of the rear connecting hole 4 is not connected to the frontmost medium flow channel 2;

[0032] Both ends of each of the medium flow channels 2 are respectively provided with mounting interfaces 5;

[0033] An interface component is installed in each of the installation interfaces 5, and the interface component blocks or opens the installation interface 5;

[0034] The front connecting hole 3 and the rear connecting hole 4 are respectively installed with blocking members 6 , and the blocking members 6 completely or partially block the corresponding front connecting hole 3 and the rear connecting hole 4 .

[0035] In this embodiment, the cooler body is installed on the oil cavity, and it fits with the oil cavity, wherein at least two interface components open the installation interface, and the other interface components block the installation interface. In this embodiment, three parallel medium flow channels are provided, the interface component at the rearmost side of the left end opens the installation interface, the interface component at the frontmost side of the right end opens the installation interface, and the other interface components block the installation interface, and the two connected installation interfaces are the medium inlet and the medium outlet respectively, a blocking member blocks the frontmost end of the front connection hole, and the blocking member is located in the front connection hole of the frontmost medium flow channel, and another blocking member blocks the rearmost end of the rear connection hole, and the blocking member is located in the rear connection hole of the rearmost medium flow channel. At this time, the front connection hole will connect the left end of the middle medium flow channel with the left end of the front medium flow channel, and the rear connection hole will connect the right end of the middle medium flow channel with the right end of the rear medium flow channel, so that the three medium flow channels form an S-shaped structure. Taking the case where the medium inlet is at the left end of the cooler body and the medium outlet is at the right end of the cooler body as an example, the cooling medium enters the medium flow channel at the rear side from the medium inlet, flows to the right, and then flows to the middle medium flow channel through the rear connection hole, flows to the left through the middle medium flow channel, and then flows to the frontmost medium flow channel along the front connection hole, and then flows to the right along the frontmost medium flow channel and flows out from the medium outlet. In this process, the cooling medium can contact various positions of the cooler body, so that the cooling effect of the entire position of the cooler body is good, so that the contact position of the cooler body and the oil cavity can be quickly heat exchanged and cooled by the cooler body.

[0036] The interface component includes an end plug 7 and a medium joint 8, wherein the medium joint 8 opens the installation interface 5 and the end plug 7 blocks the installation interface 5, and there are at least two medium joints 8. The inner surface of the installation interface has an internal thread, and the outer surface of the interface component has an external thread, so that the interface component and the installation interface can be quickly installed and removed.

[0037] In this embodiment, the medium joint is used to deliver the cooling medium into the medium flow channel and to deliver the cooling medium in the medium flow channel. Among them, there can be three medium joints. Taking three medium joints as an example, one of the medium joints is at the left end of the cooler body, and the other two medium joints are at the right end of the cooler body. The medium joint on the left is connected to the left end of the rearmost medium flow channel, and the two medium joints on the right are connected to the rearmost and frontmost medium flow channels respectively. If the medium joint on the left is the medium outlet and the two medium joints on the right are the medium inlet, the cooling medium in the rearmost medium flow channel flows at the fastest speed, and the cooling medium in the frontmost and middle medium flow channels flows at a slightly slower speed. At this time, the cooling speed of the rear side of the cooler body will be greater than the cooling speed of the middle and front sides of the cooler body. Similarly, the medium joint on the left end can be the medium inlet, and the medium joint on the right end can be the medium outlet. In this way, the flow speed of the cooling medium will be slower, and the cooling speed of the oil cavity will also be slower. Similarly, the position is adjusted according to the different cooling speeds required for different positions.

[0038] Of course, in the present invention, the number of medium flow channels may be 4, 5 or even more, and the number and position of the medium joints may be adjusted arbitrarily, thereby adjusting the cooling conditions.

[0039] See also Figures 1 to 5 As shown, the front connection hole 3 and the rear connection hole 4 are arranged between the mounting interfaces 5 at both ends of the medium flow channel 2. This does not affect the flow of the cooling medium through the mounting interface. At the same time, in this embodiment, the front connection hole and the rear connection hole are arranged perpendicular to the medium flow channel.

[0040] See also Figures 1 to 5 As shown, the outer diameters of the front connection hole 3 and the rear connection hole 4 are larger than the diameter of the medium flow channel 2, and the axes of the front connection hole 3 and the rear connection hole 4 pass through the corresponding axis of the medium flow channel 2. In this way, when the blocking piece completely blocks the corresponding connection hole, the blocking piece in the corresponding medium flow channel will separate the two ends of the medium flow channel on both sides of the corresponding connection hole and make them disconnected.

[0041] The cooler body 1 between adjacent medium flow channels 2 forms a partition bar 9, and the outer end of the blocking member 6 blocks the front connecting hole 3 and the rear connecting hole 4 on the outer side of the most side medium flow channel 2, and the inner end of the blocking member 6 is arranged close to the most side medium flow channel 2, or the inner end of the blocking member 6 is against the front connecting hole 3 or the rear connecting hole 4 in the partition bar 9.

[0042] In this way, after the blocking piece is installed into the corresponding connecting hole, for example, the middle part of the blocking piece is in one of the medium flow channels, and the two ends of the blocking piece are at the two ends of the medium flow channel, the blocking piece in the medium flow channel can block the corresponding medium flow channel.

[0043] In this embodiment, three medium flow channels are taken as an example, so there are two spacers. If the inner end of the plugging piece in the front connection hole is in the front spacer, the inner end of the plugging piece in the rear connection hole is at the rear end of the rear medium flow channel. At this time, the rear connection hole connects the rear medium flow channel and the right end of the middle medium flow channel. At this time, the two medium joints are respectively connected to the left ends of the middle medium flow channel and the rear medium flow channel. The other installation interfaces are respectively installed with end plugs. The cooling medium flows from one medium joint into the middle or rear medium flow channel, and then flows into another interconnected medium flow channel through the rear connection hole, and then flows out from another medium joint. In the utility model, the positions of the medium inlet and the medium outlet can be on the same side of the cooler body, or can be set on different sides. In this way, the positions of the medium inlet and the medium outlet can be adjusted according to the installation position and installation space of the vacuum pump, thereby improving the scope of application and convenience of use.

[0044] Similarly, by adjusting the different lengths of the plugging parts so that the plugging parts are blocked at different positions of the corresponding connecting holes, the positions of the medium inlet and medium outlet, the flow trajectory of the cooling medium, the different cooling positions and cooling speeds can be adjusted to suit different oil cavity cooling.

[0045] See also Figures 1 to 5 As shown, the cooler body 1 is provided with a plurality of mounting holes 10 penetrating the top surface and the bottom surface of the cooler body 1 , and the mounting holes 10 are arranged between adjacent medium flow channels 2 .

[0046] In this embodiment, a cavity is set at the bottom of the pump body of the vacuum pump. The cavity is below the oil cavity of the vacuum pump. The cooler body is directly installed in the cavity. The cooler body adopts a rectangular structure. The outer side surfaces of the cooler body except the bottom surface are in contact with the inner wall of the cavity respectively, which can increase the contact area with the pump body and ensure the cooling effect. The setting of the mounting hole makes it easy for the bolts to penetrate from the bottom of the mounting hole and connect with the screw hole of the pump body to realize the connection between the cooler body and the pump body. Among them, in this embodiment, the mounting hole is located on the partition bar.

[0047] At the same time, in the utility model, the end plug is installed in the installation interface, which will not occupy the space outside the cooler body, reduce the space occupied, and directly use the corresponding connecting holes to realize the connection of the medium flow channel. The medium flow channel at the edge can be used normally, or all the medium flow channels can be used, or part of the medium flow channels can be used, so as to adjust the cooling effect and cooling position, and adjust it according to the position of the oil chamber that needs to be cooled, and has a wide range of applications.

[0048] In the utility model, a panel 11 is installed on the top surface and the bottom surface of the cooler body respectively, and the panel blocks and limits the outer end of the corresponding blocking member to prevent the blocking member from shifting outward and falling.

In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0050] In the present utility model, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, or a detachable connection, or an integral one; it can be a mechanical connection, or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, for example, the two can form a mechanical abutment or abutment connection through abutment, contact, etc., the two can also be directly hung or hung through an intermediate medium, etc., or it can be the internal connection of the two elements or the interaction relationship between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
