[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] See Figs. 1-6 A vehicle-mounted heater includes a housing, which is composed of a lower housing 1 and an upper housing 4. The lower housing 1 has a cuboid structure and air inlets and outlets are respectively provided on its opposite side walls. The top surface of the lower housing 1 is open, and the upper housing 4 is disposed on the top surface of the lower housing 1 to close the top surface of the lower housing 1.

[0029] The lower housing 1 houses an axial flow fan 2 and a heater core 3. The heater core 3 is located on the air inlet side and is parallel to the air inlet. The axial flow fan 2 is located on the air outlet side and its air outlet direction is directly opposite to the air outlet. The heater core 3 has a water inlet and a water outlet. The lower housing 1 also has a first through hole and a second through hole for the water inlet pipe 5 and the water outlet pipe 6 to pass through. The water inlet pipe 5 is connected to the water inlet of the heater core 3 through the first through hole to introduce engine coolant. The water outlet pipe 6 is connected to the water outlet of the heater core 3 through the second through hole to discharge the engine coolant after heat exchange. The lower housing 1 also has a third through hole for the power supply wiring harness to pass through, so that the power supply wiring harness can be connected to the axial flow fan 2 through the third through hole to provide power.

[0030] The heater core is assembled from components such as flat tubes, fins, water chambers, and baffles using a brazing process. Any heater core currently available on the market can be used. An axial flow fan is located on the air outlet side. Under the action of the axial flow fan, cold air enters the housing from the air inlet and then exchanges heat with the heater core. The cold air absorbs heat and is converted into warm air, which is then delivered into the vehicle.

[0031] When using this vehicle-mounted heater, it is positioned under the front seats (driver's seat and / or passenger's seat) with the air outlet facing the rear seats. It can be installed under the driver's seat or passenger seat, or both, depending on heating needs. The axial flow fan uses streamlined blades and a cylindrical casing design, resulting in a compact, thin, and lightweight structure. This effectively reduces the size of the vehicle-mounted heater. The dimensions of this vehicle-mounted heater can be as small as approximately 200mm × 40~50mm × 100mm, allowing it to be installed in the narrow space under car seats to provide heating for rear passengers.

[0032] In a specific implementation, the bottom of the lower housing 1 is provided with several mounting seats 8, and the mounting seats 8 are provided with mounting holes, so as to fix the lower housing 1 in the vehicle with bolts. In this embodiment, there are four mounting seats and they are divided into two groups, which are respectively set on the front and rear sides of the lower housing (the side where the air inlet is located is the rear side, and the side where the air outlet is located is the front side).

[0033] In practice, there are two axial flow fans 2, arranged side by side. A speed-regulating damper is also included to adjust the power of the axial flow fans.

[0034] In specific implementation, the lower shell 1 and the upper shell 4 are provided with limiting ribs for locking the heating core 3 and the axial flow fan 2, and the heating core 3 and the axial flow fan 2 are locked in the corresponding limiting ribs.

[0035] In specific implementation, the lower housing 1 has a first notch with an upward opening on both sides of the side wall corresponding to the air outlet. The lower end of the first notch is semi-circular. Correspondingly, the upper housing 2 has a second notch with a downward opening. The second notch is semi-circular. The two first notches and the corresponding second notches are respectively provided with pipe clamps and wire clamps. The two ends of the pipe clamp 7 have semi-circular grooves, which together with the lower end of the first notch and the second notch form the first through hole and the second through hole. The two ends of the wire clamp 9 have semi-circular protrusions, and one of the protrusions is provided with a through hole, which constitutes the third through hole.

[0036] In this way, the air outlet of the housing formed by the lower and upper housings has two notches on both sides, and the two notches are symmetrically arranged. At the same time, the two ends of the two notches are semi-circular grooves. This way, when manufacturing the housing, the same set of molds can be used to prepare a heater housing suitable for installation under the driver's seat and the passenger seat. When using it, only the position of the pipe clamps and wire clamps needs to be changed.

[0037] In specific implementation, the pipe clamps 7 and 9 are provided with grooves 10 on both the left and right sides that correspond to the wall thickness of the lower housing 1, so that the pipe clamps 7 and 9 can be fastened to the lower housing 1 through the grooves 10. This allows for edge removal and replacement of the pipe clamps and 9.

[0038] In practice, the top surface of the lower housing 1 is evenly distributed with a number of first connecting holes, and the upper housing 4 is provided with second connecting holes that correspond one-to-one with the first connecting holes, so that the upper housing 4 and the lower housing 1 can be fixedly connected by bolts.

[0039] In specific implementation, the lower housing 1 corresponding to the air inlet and air outlet is provided with a grille to seal the air inlet and air outlet. At the same time, cold air can enter the housing through the grille, and warm air can enter the vehicle through the grille. The grille can prevent debris from entering the housing and protect the heater. In this embodiment, the grille and the lower housing are integrally formed.

[0040] Finally, it should be noted that the above embodiments of this utility model are merely examples for illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations and modifications based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
