Description

Technical Field

[0001] This application relates to the field of automotive technology, and more specifically, to a side-ventilated columnar PTC heater and an automobile. Background Technology

[0002] A PTC air heater is a device that uses PTC ceramic heating elements for heating. It is widely used in appliances such as air heaters, dryers, electric ovens, and automobiles. PTC ceramic heating elements have advantages such as high efficiency, safety, energy saving, wide applicability, and long lifespan. In an air heater, the PTC ceramic heating element heats the air, raising its temperature and thus providing a heating effect. When used in a car, an air heater can heat the interior space. There are many types of car air heaters on the market, most of which are flat.

[0003] Utility model patent with authorization announcement number 202221967603.5 discloses an automotive PTC heater, including a PTC heating structure, a controller, a heating shell, and a control shell. The controller is disposed in the control shell, and the PTC heating structure is electrically connected to the controller. The heating shell includes a heating base and two heating side plates arranged at a predetermined distance from each other. One end of each heating side plate is detachably connected to the control shell, and the other end of each heating side plate is detachably connected to the heating base. The PTC heating structure is disposed in the heating space enclosed by the heating base, the two heating side plates, and the control shell. In this utility model, the two ends of the two heating side plates of the heating shell are detachably connected to the control shell and the heating base, and the heating shells are installed together by interlocking, eliminating the need for screw fastening. The manufacturing process is complex, but installation and disassembly are very convenient.

[0004] Utility model patent with authorization announcement number 201920990151.4 discloses a novel PTC heater for air conditioning, which solves the technical problems of existing PTC heaters for vehicle air conditioning, such as low protection level, short lifespan, slow heat dissipation, and large weight and size. It comprises a shell, a PTC heating element, a manifold bracket, and a manifold. The shell is divided into an upper shell, side shells, and a lower shell, which together form a heating cavity. The PTC heating element is located within the heating cavity and has alternating heat dissipation strips and heating blocks. A manifold bracket and a manifold are located above the PTC heating element, and the manifold bracket is glued to the upper shell. The top of the upper shell has a waterproof silicone groove and a waterproof silicone ring. The side shell has a side shell groove that engages with the heat dissipation strips on both sides of the PTC heating element. The lower shell has a lower shell groove that mates with the tail of the PTC heating element. A silicone pad is placed between the PTC heating element and the lower shell groove. This utility model can be widely used in the field of heating devices.

[0005] While the aforementioned technical solutions have their advantages, their plate-like structure presents challenges in practical application. Since the wiring ports of plate-like heaters are typically located on only one side, installation requires ensuring that the wiring port is aligned with the wiring port on the vehicle. If the heater is placed incorrectly, wiring becomes impossible, necessitating removal and adjustment, which wastes time and inconveniences the user. Therefore, we propose a side-blowing columnar PTC heater for automobiles. Summary of the Invention

[0006] The purpose of this application is to provide a side-blown columnar PTC heater and an automobile to solve the technical problems of plate heaters in the prior art, such as incorrect placement, inability to properly wire, and delay in operation.

The mesh plate is located inside the air hood, and an air hood with a front side connected to the outside is provided inside the air hood. The air hood is used for air venting and is used to connect to an external pipeline for easy pipeline connection and hot air delivery.

[0010] In one embodiment, end protrusions are fixedly installed on both the left and right sides of the vent hood. The end protrusions are used to fix and connect with the external pipe cover, making the installation and connection operation more convenient.

[0011] In one embodiment, an inner fixing ring is fixedly installed on the inner wall at the top of the semi-cylinder. The inner fixing ring is hollow. The heater includes a base plate, and an upper support ring is provided above the base plate. Multiple PTC ceramic heating element fixing plates arranged in a ring at equal intervals are fixedly installed between the base plate and the upper support ring. Both the base plate and the PTC ceramic heating element fixing plates are inserted into the semi-cylinder. The upper support ring is fixedly installed on the upper surface of the inner fixing ring by multiple fastening screws. Ventilation holes are provided in the PTC ceramic heating element fixing plates along the height direction of the PTC ceramic heating element fixing plates. Multiple PTC ceramic heating elements are fixedly installed on the walls of the ventilation holes in a linear and equal-interval arrangement along the vertical direction, so as to facilitate the use of PTC ceramic heating elements for heating and achieve the effect of heating.

[0012] In one embodiment, a wire-passing hole is provided on both the inner fixing ring and the inner wall at the top of the semi-cylinder. The wire-passing hole is used for wiring operations, enabling normal wiring and connection operations.

[0013] In one embodiment, a plurality of guide posts arranged in a ring at equal intervals are fixedly installed on the bottom wall of the semi-cylinder, and a plurality of guide holes arranged in a ring at equal intervals are provided on the bottom plate. The guide posts are located in the guide holes and are inserted into the guide holes to guide and limit the bottom plate, which facilitates the installation of the bottom plate and makes the installation more convenient.

[0014] In one embodiment, a positive conductive post is fixedly installed on the upper surface of the upper support ring, and a negative conductive post is also fixedly installed on the upper surface of the upper support ring. The positive and negative conductive posts are electrically connected to the PTC ceramic heating element, and the positive and negative conductive posts are used for wiring operations.

[0015] In one embodiment, an outer fixing ring is fixedly installed at the top of the semi-cylinder, and a lower ring is fixedly installed at the bottom of the support cylinder. The lower ring and the outer fixing ring are fixedly connected by multiple fastening screws. A collar is fixedly installed at the center of each group of multiple fan blades. The collar is sleeved on the output shaft of the drive motor and fixedly connected to the output shaft of the drive motor by multiple fastening screws, which facilitates the fixed installation of the support cylinder and the fan blades.

[0016] In one embodiment, a plurality of connecting rods arranged in a ring at equal intervals are fixedly installed on the housing of the drive motor, and a plurality of bolt plates arranged in a ring at equal intervals are fixedly installed on the top cylinder of the support cylinder.

A stud is fixedly installed at the end of the output shaft of the drive motor, and a nut is threaded onto the stud. The nut abuts against the bottom surface of the collar located below, which facilitates further limiting of the collar and prevents the collar from falling off the output shaft of the drive motor.

[0017] On the other hand, this application also provides an automobile, including the aforementioned side-venting columnar air-heating PTC heater, and a connecting assembly for mounting and connecting the side-venting columnar air-heating PTC heater.

[0018] The beneficial effects of the side-ventilated columnar PTC heater provided in this application on automobiles are at least as follows:

[0019] 1. With the outer cylinder, heater and air conveying assembly, the heater can heat the air and the air conveying assembly can deliver air to achieve wind heating operation. In addition, since the outer diameters of the base plate and the upper support ring are different, the corresponding parts on the plate are also different. This allows for intuitive and clear installation of the heater during assembly, making it convenient to use and achieving the effect of error-free installation and saving time.

[0020] 2. The guide posts and guide holes facilitate the guiding and installation of the base plate, and the inner fixing ring facilitates the fixing of the upper support ring, thus achieving the effect of facilitating the fixed installation of the heater.

[0021] 3. The collar is fixed to the output shaft of the drive motor with fastening bolts, which facilitates installation and disassembly. In addition, nuts are used for limiting, which further prevents the collar from slipping. Attached Figure Description
