[0029] Figure 1 The schematic diagram of the structure of the cab with a cooling and heating system of the utility model is shown. Figure 1 As shown, the cab with a cooling and heating system of the utility model comprises a cab body 1. The cab body 1 is a cab body of an agricultural vehicle.
[0030] The bottom of the cab body 1 is provided with running wheels so that the cab body 1 can move. In addition, a driver's seat and a steering wheel are also installed in the cab body 1 so that the driver can sit on the driver's seat and operate the steering wheel.
[0031] In the present invention, a first heat exchanger 2, a second heat exchanger 3 and a third heat exchanger 4 are installed in the cab body 1. A heat exchanger 5 and a liquid pump 6 are arranged outside the cab body 1.
[0032] The first heat exchanger 2, the second heat exchanger 3 and the third heat exchanger 4 are all connected to one side of the heat exchanger 5 through the liquid pump 6 and are provided with a flowable heat exchange medium, such as water, so that the gas in the cab body 1 can exchange heat with the heat exchange medium through the first heat exchanger 2, the second heat exchanger 3 and the third heat exchanger 4. The other side of the heat exchanger 5 is connected to a heat source or a cold source to heat or cool the heat exchange medium.
[0033] Specifically, Figure 1 and 2As shown, one end of the liquid pump 6 is connected to the inlets of the first heat exchanger 2, the second heat exchanger 3 and the third heat exchanger 4 through a removal pipe 7, and the other end is connected to the outlet of one side of the heat exchanger 5. The outlets of the first heat exchanger 2, the second heat exchanger 3 and the third heat exchanger 4 are connected to the inlet of one side of the heat exchanger 6 through a loop pipe 8. At the same time, the inlet of the other side of the heat exchanger 5 is connected to the outlet of the heat source or cooling, and the outlet of the other side of the heat exchanger is connected to the inlet of the heat source or cooling.
[0034] Therefore, when the weather is hot, an external cold source can be used, for example, a high-pressure cold air tank is used as an external cold source, the inlet on the other side of the heat exchanger 5 is connected to the outlet of the high-pressure cold air tank and the outlet on the other side of the heat exchanger 5 is connected to the inlet of the high-pressure cold air tank. Thus, the high-pressure cold air in the high-pressure cold air tank can be heat-exchanged with the heat exchange medium through the heat exchanger 5 to cool the heat exchange medium (water). At the same time, the cooled heat exchange medium circulates under the action of the liquid pump 6, and heat-exchanges with the air in the cab body 1 at the first heat exchange element 2, the second heat exchange element 3 and the third heat exchange element 4 to cool the air in the cab body 1, thereby providing a cooling effect for the driver.
[0035] When the weather is cold, an external cold source can be used, for example, the waste heat of the engine can be used as an external heat source, and the inlet on the other side of the heat exchanger 5 is connected to the outlet of the external heat source and the outlet on the other side of the heat exchanger 5 is connected to the inlet of the external heat source. Thus, the hot air in the external heat source can be heat-exchanged with the heat exchange medium (water) through the heat exchanger 5 to heat the heat exchange medium (water). At the same time, the heated heat exchange medium circulates under the action of the liquid pump 6, and heat-exchanges with the air in the cab body 1 at the first heat exchange element 2, the second heat exchange element 3 and the third heat exchange element 4 to heat the air in the cab body 1, thereby providing a heating effect for the driver.
[0036] In the present invention, preferably, the first heat exchanger 2 is mounted on the bottom plate of the cab body 1, the second heat exchanger 3 is mounted on the top plate of the cab body 1, and the third heat exchanger 4 is mounted on the rear plate of the cab body 1. Thus, the air in the cab body 1 can be heated or cooled from different positions, thereby achieving a better heating or cooling effect.
[0037] The structures of the first heat exchange element 2, the second heat exchange element 3 and the third heat exchange element 4 are the same. Therefore, for simplicity, in the present invention, the first heat exchange element 2 is taken as an example to introduce their specific structures.
[0038] like Figure 3-5 As shown, the first heat exchange member 2 includes a plurality of heat exchange tubes 21 and a first connecting tube 22 and a second connecting tube 23. The first connecting tube 22 is connected to the bottom of the plurality of heat exchange tubes 21, and the second connecting tube 23 is connected to the upper part of the plurality of heat exchange tubes 21. Thus, the plurality of heat exchange tubes 21 can be connected in series with each other through the first connecting tube 22 and the second connecting tube 23. Thus, a better heat exchange effect can be obtained.
[0039] Furthermore, the second connecting pipe 23 is provided with an inlet 25 and an outlet 26. The inlet 25 is connected to the outlet of the liquid pump 6 through the outgoing pipe 7. The outlet 26 is connected to the inlet of one side of the heat exchanger 6 through the loop pipe 8. Thus, the circulation of the heat exchange medium can be achieved.
[0040] Finally, in the present invention, preferably, the first heat exchange member 2 further comprises a connecting sheet 24. The plurality of heat exchange tubes 21 are connected together through the connecting sheet 24. Thus, the plurality of heat exchange tubes 21 are conveniently connected together better.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Those skilled in the art can modify or replace the technical solution of the utility model according to the idea of the utility model without departing from the essence and scope of the technical solution of the utility model.
