The following describes the implementation method of the present utility model based on its overall structure.

[0032] Reference Figure 1 As shown, an embodiment of the present application provides an electric compressor with an integrated heating module, comprising:

[0033] Compressor 1;

[0034] A heating module 2 is fixedly connected to the upper side of the compressor 1, and the heating module 2 has the same extension trend as the compressor 1;

[0035] The heat exchange module 3 is connected to the heating module 2, and a heat exchange chamber 31 is provided in the heat exchange module 3. The heat exchange chamber 31 is used to circulate the heat-conducting medium. A heating chamber 21 is provided in the heating module, and a heating body 24 is connected to the heating chamber 21. The heating body 24 is used to heat the heat-conducting medium and / or the compressor 1.

[0036] according to Figure 1 , those skilled in the art can arrange a heating module 2 on the outside of the compressor 1. It is worth noting that the heating module 2 and the compressor 1 maintain the same extension trend.

[0037] It is understandable that the heating module 2 is mounted on the outer wall of the compressor 1. The main body of the compressor 1 can be extended during the setting, and the heating module 2 can also be extended at the position where it is set on the outer wall of the compressor 1. In this embodiment, the extension direction of the heating module 2 and the compressor 1 remains the same.

[0038] In one embodiment, the compressor 1 may be arranged to extend from the position of the air inlet toward a position away from the air inlet. The heating module 2 is arranged on the outer wall of the compressor 1 in the same direction as the extension direction of the compressor 1 .

[0039] Furthermore, the compressor 1 extends along its long axis. The heating module 2 extends along its long axis. In this embodiment, the extension direction trends of the compressor 1 and the heating module 2 remain the same. For example, the extension directions of the compressor 1 and the heating module 2 may be parallel to each other, or, in some optional embodiments, the extension directions of the compressor 1 and the heating module 2 may be at a certain smaller angle. Obviously, structurally speaking, the electric compressor with an integrated heating module adopting this structure occupies less space and has better integration.

[0040] In the above structure, the heating module 2 is arranged on the outer wall of the compressor 1, so that the compressor 1 can heat the heat-conducting medium during the process of gas compression and heating.

[0041] With the above structure, the heating module 2 can be configured as an open structure, and a heating chamber 21 is provided inside the heating module 2. That is, a person skilled in the art can install a heating body 24 in the heating chamber 21.

[0042] A heating chamber 21 is defined in the heating module 2, and a support plate 22 is fixedly connected to the mounting side of the inner wall of the heating chamber 21. The support plate 22 extends toward the side wall of the heating chamber 21 relative to the mounting side 23, and the support plate 22 is separated from the side wall of the heating chamber 21 relative to the mounting side 23, so as to form a first cavity 211 and a second cavity 212 which are interconnected in the heating chamber 21.

[0043] In the structure for installing the heating body 24, a person skilled in the art may arrange that a support plate 22 is installed in the heating chamber 21. The support plate 22 is installed on the first side 23 in the heating chamber 21, and the support plate 22 extends toward the side wall in the heating chamber 21 relative to the installation side 23. Specifically, the support plate 22 is separated from the side wall in the heating chamber 21 relative to the installation side 23. The structure for installing the support plate 22 may divide the heating chamber 21 into a first cavity 211 and a second cavity 212. Furthermore, the first cavity 211 and the second cavity 212 remain connected.

[0044] A heat exchange module 3 is also provided between the heating module 2 and the compressor 1. A person skilled in the art may provide a heat exchange chamber 31 in the heat exchange module 3. The heat transfer medium may be circulated through the heat exchange chamber 31.

[0045] It is understandable that the heat exchange cavity 31 is connected to the first cavity 211. That is, in the structure in which the heating module 2 and the heat exchange module 3 are connected to each other, a heating body 24 can be provided to heat the heat transfer medium, and the cab of the vehicle can be heated by the heat transfer medium.

[0046] In the above structure, the heater 24 can also heat the outer wall of the compressor 1 by heat radiation during the heating process, so that the compressor 1 can effectively have a certain temperature during the intake process, and the compressor 1 can have a higher temperature of exhaust gas after compressing and heating the gas.

[0047] In summary, a person skilled in the art can arrange the heating body 24 to be installed on the support plate 22, heat the first cavity 211 through the heating body 24, and then heat the heat transfer medium in the heat exchange cavity 31 through the first cavity 211. The heating body 24 can also heat the outer wall of the compressor 1 by heat radiation. The aforementioned heating process can make the compressor 1 quickly heated at a low temperature.

[0048] In the setting of the heating chamber 21, the heating chamber 21 is divided into a first cavity 211 and a second cavity 212 which are connected to each other by the support plate 22. Preferably, the width of the first cavity 211 is greater than the width of the second cavity 212. That is, the width of the second cavity 212 in which the heating body 24 is set is smaller than the width of the first cavity 211 through which the heat-conducting medium is heated. The above-mentioned structure can increase the heating time of the heat-conducting medium, and thus can make the heat-conducting medium be heated evenly.

[0049] Preferably, a liquid inlet 32 ​​and a liquid outlet 33 are fixedly opened on the end side of the heat exchange chamber 31 away from the control box 11. Figure 1 , those skilled in the art can set the liquid inlet 32 ​​and the liquid outlet 33 to be opened on the side wall of the heat exchange chamber 31 away from the control box 11. Then the heat transfer medium can be effectively and stably circulated. Those skilled in the art can install the control box 11 on the outer wall of the compressor 1. The start and shut down of the device in the compressor 1 can be controlled by the control box 11. Furthermore,

[0050] In summary, in the process of heating the heat-conducting medium, the heat-conducting medium is circulated into the heat exchange cavity 31 through the liquid inlet 32. The heating is performed by the heating body 24, and the width of the first cavity 211 is greater than the width of the second cavity 212, so that the heat-conducting medium can be effectively and evenly heated. Preferably, the liquid outlet 33 can be connected to the cab equipment through a pipeline. Thus, the heating and circulation of the heat-conducting medium can be effectively realized, and the temperature in the cab can be increased by the heated heat-conducting medium.

[0051] By means of the above structure, those skilled in the art can perform heat insulation treatment on the pipe connected to the liquid outlet 33, thereby effectively preventing the high-temperature heat-conducting medium from damaging other parts inside the vehicle.

[0052] The heater 24 is further arranged, preferably, the heater 24 is installed near the air inlet of the compressor 1. The air discharged from the air inlet of the compressor 1 can be heated by the heater 24. The air inlet temperature of the compressor 1 is increased, and the air outlet temperature can be effectively increased. The compressor 1 can work quickly in a low temperature environment, and the vehicle cockpit can be heated quickly in a low temperature environment.

[0053] In the process of setting the heater 24, preferably, the heater 24 can be set to PTC, and the heating of the heater 24 can be controlled by electric control, so that those skilled in the art can control and adjust the working condition of the heater 24 according to the actual situation.

[0054] In one embodiment, preferably, the plane where the heating body 24 is located is parallel to the plane where the support plate 22 is located. Thus, the heating body 24 can heat the heat-conducting medium uniformly. It is understandable that the plane where the heating body 24 is located is parallel to the plane where the support plate 22 is located, so that the area heated by the heating body 24 can be increased. Thus, the heating of the heat-conducting medium is more uniform.

[0055] Preferably, the outer wall of the heat exchange module 3 is fixedly connected with a plurality of first mounting columns 34, and the outer wall of the compressor 1 is fixedly connected with a plurality of second mounting columns 12, and the plurality of first mounting columns 34 correspond one-to-one with the plurality of second mounting columns 12. According to the above arrangement, the compressor 1 and the heat exchange module 3 can be stably fixedly connected by the one-to-one correspondence between the plurality of first mounting columns 34 and the plurality of second mounting columns 12.

[0056] In one embodiment, a threaded hole may be provided in the first mounting column 34, and a bolt may be provided to pass through the threaded hole on the first mounting column 34 and into the second mounting column 12, so that the compressor 1 and the heat exchange module 3 can be stably connected.

[0057] In the actual installation process of the heating module 2, preferably, a rear cover is installed on the side of the second cavity 212 away from the support plate 22. That is, those skilled in the art can seal the heating cavity 21 by installing the rear cover. Thus, the heating cavity 21 and the heat exchange cavity 31 can be isolated from the outside world. Thus, the heating body 24 is prevented from damaging other parts during the heating process.

[0058] In one embodiment, preferably, the connection between the rear cover and the heating module 2 is sealed, thereby effectively preventing leakage of the heat transfer medium, thereby allowing the heating module 2 and the heat exchange module 3 to heat stably.

[0059] In the actual implementation process, the heating body 12 is a combination of one or more of a PTC heater, a thin film heater and a thick film heater. It is understandable that the heating body 12 is set as a PTC heater, which has the characteristics of rapid heating, automatic temperature control in the event of a fan failure, and long service life compared to other heaters.

The embodiments of data acquisition, processing, output, judgment methods, etc. after these modifications or deformations can still fall within the scope of the optional implementation plans of this application.
