Description

Technical Field

[0001] The utility model belongs to the technical field of light commercial vehicles, relates to a light commercial vehicle heater, and specifically relates to a light commercial vehicle heater pipeline. Background Art

[0002] Light passenger heaters are important comfort features in light buses, providing heating for the interior of light buses. Their operating principle is similar to that of automobile heaters, primarily consisting of a ventilator, an electric motor, and an air heater. Currently, light passenger heaters are installed in the passenger compartment, with the heater piping directly connected in series with the engine's water circuit. When the engine is running, the cooling water absorbs the heat generated by the engine, which is then transported into the vehicle via the heater's fan, creating warm air. However, even if the heater's power switch is disconnected and the fan stops, the heater's piping is directly connected in series with the engine's water circuit, allowing for natural heat dissipation. This can easily cause the passenger compartment to overheat, especially in the summer. Utility Model Content

[0003] In response to the above problems, the main purpose of the present invention is to design a light commercial vehicle heater pipeline. By setting a two-position four-way solenoid valve, the heater pipeline is isolated from the engine water circuit when the heater power switch is disconnected, thereby solving the natural heat dissipation problem caused by directly connecting the heater pipeline in series in the engine water circuit.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A light passenger car heater pipe is used to set the heater in the engine water channel, including a heater, a solenoid valve, a heater water inlet pipe, a heater water outlet pipe, and a heater power switch for controlling the heater;

[0006] One end of the warm air inlet pipe is connected to the inlet of the heater and the solenoid valve, and the other end is connected to the engine cooling water outlet;

[0007] One end of the warm air outlet pipe is connected to the outlet of the heater and the solenoid valve, and the other end is connected to the engine cooling water inlet.

[0008] As a further description of the present invention, the solenoid valve is configured as a two-position four-way solenoid valve.

[0009] As a further description of the present invention, when the power switch of the heater is closed, the two-position four-way solenoid valve and the fan of the heater are both in working state.

[0010] As a further description of the present invention, when the power switch of the heater is turned off, the two-position four-way solenoid valve is in a reset state and the fan of the heater is in a stopped state.

[0011] Compared with the prior art, the technical effects of the present invention are:

[0012] The utility model provides a light commercial vehicle heater pipeline, comprising a heater, a two-position four-way solenoid valve, a heater water inlet pipe, a heater water outlet pipe, and a heater power switch; when the heater power switch is closed, the two-position four-way solenoid valve and the heater fan are in working condition, and the engine cooling water flows back to the engine through the heater water inlet pipe, the heater, and the heater water outlet pipe, and the heater fan sends heat into the vehicle to form warm air; when the heater power switch is disconnected, the two-position four-way solenoid valve is in a reset state, the heater fan stops, and the engine cooling water flows back to the engine directly through the heater water inlet pipe and the heater water outlet pipe, and the heater pipeline is completely isolated from the engine water circuit; a relatively flexible and controllable heater system is provided, which meets various needs in actual use and improves the controllability and efficiency of the heater system.
