Description

Technical Field

[0001] This utility model relates to the field of component improvement design technology for daily heating equipment, and in particular to a heating component with forced convection function. Background Technology

[0002] Convection heaters are household appliances that regulate air temperature. They work by installing a heating element inside the unit, with convection ventilation holes at the bottom and convection heat dissipation holes at the top. When the heating element is powered on, the surrounding cool air is radiated and becomes hot air, rising and exiting through the top vents. Meanwhile, cool air inside the unit is replenished through the bottom ventilation holes, creating a natural convection flow for heat exchange. However, relying on natural convection limits the efficiency of hot air exiting from the top, significantly impacting the rate of indoor air heating and the uniformity of ambient temperature. This results in a poor user experience and wasted energy.

[0003] Currently, heaters with forced convection fans on the market all have separate fans and heating elements, which are two separate structural components. This takes up a lot of space, resulting in a larger heater size. Larger heaters take up more indoor space and cannot meet users' demand for smaller heaters. At the same time, because they are two separate parts, the assembly time of the heater is increased.

[0004] In the prior art, patent CN215951543U discloses a forced convection heater, including a shell and a heating element and a fan assembly disposed inside the shell. The shell has a first air inlet at its bottom and an air outlet at its top. The heating element is fixed below the air outlet, and the fan assembly is disposed between the heating element and the first air inlet, with its air inlet facing the first air inlet and its air outlet facing the heating element. This invention achieves forced convection by incorporating a fan assembly within the heater. The fan assembly accelerates airflow, assisting natural convection to speed up the heat exchange rate of the heating element, reducing the surface temperature of the shell. Simultaneously, the heat dissipation efficiency of the heating element is improved, the operating time of the heating element is shortened, and energy and electricity are saved.

[0005] Patent CN218864307U discloses a baseboard electric heater, including a DC fan and a heater housing. The heater housing comprises a front shell, a rear shell, a left shell, and a right shell. The DC motor is connected to the rear shell, and the rear shell is connected to a left side plate and a right side plate. The left side plate and the right side plate are connected to a heating element support, and the heating element support is connected to the heating element. The rear shell is connected to an upper cover vent grille and a lower cover grille, and the lower cover grille is connected to a foot bracket assembly. This utility model has a natural convection working mode and a forced convection working mode. The baseboard electric heater uses a DC fan for forced convection, and different working modes are selected by controlling whether the fan rotates. The DC fan and the heating element are placed parallel to each other and on the same horizontal plane, which can improve the utilization rate of the fan's air output and make the forced convection effect better. It can also blow out the heat generated by the heating element in the shortest stroke, reducing heat loss.

[0006] In order to solve one of the above problems, this application provides a heating component with forced convection function. Utility Model Content

[0007] The purpose of this utility model is to solve the problems existing in the prior art by proposing a heating component with forced convection function. By combining the blower and heating element components together, the overall volume is reduced, meeting the customer's need for product miniaturization, saving customers packaging, transportation and assembly costs, and helping to improve the market competitiveness of customer products.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a heating component with forced convection function, including a mounting shell, wherein a through mounting cavity is provided in the mounting shell, and a blower and a heating element assembly are provided in the mounting cavity, so that the mounting shell, the blower and the heating element assembly can be assembled into a whole for direct use. The blower draws in air and blows air onto the heating element assembly to assist in heat dissipation, which can meet the forced convection heat dissipation requirements of the heating element assembly.

[0009] Furthermore, as described above, the blower and heating element assembly are respectively installed at both ends of the mounting cavity, so that the blower and heating element assembly can be integrated into a single structure, reducing the space occupied by separate installation, meeting the miniaturization requirements of heating equipment products, and saving assembly, packaging and transportation costs.

[0010] Furthermore, as described above, the mounting housing is the first mounting housing, the blowing component is the impeller, the impeller is driven by the first motor after speed reduction, and the impeller is generally a cross-flow impeller and there is only one impeller.

[0011] Furthermore, as described above, the two ends of the wind turbine are respectively mounted on the first mounting housing, and the first motor is fixed outside the first mounting housing and connected to the shaft of the wind turbine via a coupling.

[0012] Furthermore, as described above, the first mounting housing is provided with a first air inlet, a fan wheel is installed at the first air inlet, and the first mounting housing is also provided with a corresponding first air outlet, a heating element assembly is installed at the first air outlet, and one or more heating element assemblies are provided and located at the first air outlet. The first motor drives the fan wheel to rotate, and air is drawn in from the first air inlet, driven by the fan wheel, and then forcibly discharged from the first air outlet, thereby carrying away the heat generated by the heating element assembly itself and improving the convective heat dissipation efficiency.

[0013] Furthermore, as described above, the mounting housing is a second mounting housing, and the blowing component is a fan, specifically an axial fan.

[0014] Furthermore, as described above, the fan is fixed to the second mounting housing.

[0015] Furthermore, as described above, the second mounting housing is provided with a second air inlet, at which a fan is fixed. The second mounting housing is also provided with a corresponding second air outlet, at which a heating element assembly is installed. One or more fans are located at the second air inlet, and one or more heating element assemblies are located at the second air outlet. Figure 6 As can be seen, when the fan is powered on, it blows air from the outside into the mounting cavity. The air passes through the heating element assembly, carrying away the heat from the heating element and forming hot air that is discharged, thus accelerating the efficiency of convection heat dissipation.

[0016] Furthermore, the heating element assembly described above includes a heating tube and several heat sinks fitted onto the heating tube. The heating tube is made of stainless steel, iron, or aluminum, and the heat sinks are made of aluminum, which has good heat dissipation. The aluminum surface may or may not be coated, making it easy to form and process. A first temperature controller is installed between two adjacent heat sinks. The first temperature controller may be a thermocouple, a ceramic first temperature controller, or a snap-action first temperature controller. The heat sinks are arranged at a certain interval and then cold-pressed together with the heating tube.

[0017] Furthermore, as described above, the first thermostat is fixed on the mounting plate, which is fitted onto the heating element. The installation design of the first thermostat ensures timely temperature measurement and control without occupying additional space, thus optimizing the overall design dimensions. The mounting plate and the heating element are also assembled together by cold pressing. A second thermostat is also installed on the mounting shell. Both the first and second thermostats are connected to a fuse assembly for safety protection.

[0018] Compared with the prior art, the beneficial effects of this utility model are: by combining the blower and heating element components together, this device reduces the overall volume, meets the needs of customers for product miniaturization, saves customers packaging, transportation and assembly costs, and helps improve the market competitiveness of customers' products. At the same time, by adding the blower on the basis of natural convection, it can realize the conversion from natural convection to forced convection working mode, thereby improving heating efficiency.

[0019] Installing one or more primary thermostats inside the heating element assembly provides more sensitive and faster temperature sensing and control compared to most primary thermostats installed on the main body of electric heaters and fan heaters. This improves safety and meets the needs of customers for product miniaturization.

[0020] The heating element assembly uses a string aluminum fin heating element, which is safe, has good heat dissipation, and a long lifespan. The string aluminum fin heating element consists of a heating tube and aluminum heat sinks. Several aluminum heat sinks are strung together on the heating tube and riveted tightly. The heat from the heating tube is dissipated through the aluminum heat sinks, which greatly improves the heat dissipation effect of the heating element, enhances the product's performance, and improves the user experience.

[0031] Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, those skilled in the art can...

[0033] All other embodiments obtained without creative effort are within the scope of protection of this utility model.

[0034] Example 1

[0035] Reference Figure 1-7 As shown, a heating element with forced convection function according to this utility model includes a mounting shell with a through mounting cavity. The mounting cavity contains a blower and a heating element assembly 1, which are used to install the blower and heating element assembly 1 at opposite ends of the mounting cavity. This allows the blower and heating element assembly 1 to be combined, reducing the space occupied by separate installations, meeting the miniaturization requirements of heating equipment products, and saving assembly, packaging, and transportation costs. The forced convection function refers to the blower drawing air from the outside and blowing it onto the heating element assembly 1 to assist in heat dissipation.

[0036] This invention enables forced convection by incorporating a blower in the mounting housing. The blower accelerates airflow, assists natural convection to speed up the heat exchange rate of the heating element, reduces the surface temperature of the mounting housing, and simultaneously improves the heat dissipation efficiency of the heating element assembly 1, shortens the working time, and saves energy and electricity.

[0037] Example 2

[0038] Reference Figure 1-3 As shown, based on the technical solution of Embodiment 1, a heating component with forced convection function is provided. The mounting shell is a first mounting shell 21, and the blowing component is a fan wheel 3. The fan wheel 3 is driven by a first motor 30 after speed reduction. Specifically, the two ends of the fan wheel 3 are respectively mounted on the first mounting shell 21, and the first motor 30 is fixed outside the first mounting shell 21 and connected to the rotating shaft of the fan wheel 3 through a coupling.

[0039] Furthermore, the first mounting shell 21 is provided with a first air inlet, and a fan wheel 3 is installed at the first air inlet. The fan wheel 3 is a cross-flow fan wheel. The first mounting shell 21 is also provided with a corresponding first air outlet, and a heating element assembly 1 is installed at the first air outlet.

[0040] Furthermore, there are one or more first motors 30, one impeller 3 is generally provided and located at the first air inlet, and one or more heating element assemblies 1 are provided and located at the first air outlet, such as... Figure 3 It can be seen that the first motor 30 drives the fan wheel 3 to rotate, and air is drawn in from the first air inlet, driven by the fan wheel 3, and then forcibly discharged from the first air outlet, thereby taking away the heat generated by the heating element component 1 itself and improving the convective heat dissipation efficiency.

[0041] This utility model device uses a long strip-shaped cross-flow impeller to drive the airflow. When the first motor 30 drives the cross-flow impeller to rotate at high speed, the driven air passes through the heating element assembly 1 and is discharged from the first air outlet, which creates negative pressure inside the first mounting hole 21. This forces the air outside the first mounting shell 21 to be drawn in from the first air inlet to replenish it, thereby accelerating the heat exchange rate of the heating element assembly 1. This allows the indoor air to circulate rapidly, making the indoor temperature more uniform and improving the user experience.

[0042] Example 3

[0043] Reference Figure 4-6As shown, based on the technical solution of the above embodiment, a heating component with forced convection function is provided. The mounting shell is a second mounting shell 22, and the blowing component is a fan 4. The fan 4 is an axial flow fan, and the fan 4 is fixed on the second mounting shell 22. In addition, the second mounting shell 22 is provided with a second air inlet, at which the fan 4 is fixed. The second mounting shell 22 is also provided with a corresponding second air outlet, at which the heating element component 1 is installed.

[0044] Furthermore, one or more fans 4 are located at the second air inlet, and one or more heating element assemblies 1 are located at the second air outlet, such as... Figure 6 It can be seen that when the fan 4 is powered on, it blows air from the outside into the mounting cavity. The air passes through the heating element assembly 1, carries away the heat from the heating element, and forms hot air to be discharged, thus accelerating the efficiency of convection heat dissipation.

[0045] The forced convection working mode of this utility model device uses an axial flow fan for forced convection. The axial flow fan draws in cold air from the second air inlet and blows out hot air through the second air outlet. The axial flow fan and the heating element assembly 1 are placed parallel to each other and on the same horizontal plane. This can improve the utilization rate of the air output of the axial flow fan, make the forced convection effect better, and blow out the heat generated by the heating element assembly 1 in the shortest stroke, reducing heat loss.

[0046] like Figure 7As shown, for the specific structural design of the heating element assembly 1, the heating element assembly 1 includes a heating tube 13 and a plurality of heat sinks 12 sleeved on the heating tube 13, and a first temperature controller 10 is installed between two adjacent heat sinks 12. Specifically, the first thermostat 10 is fixed on the mounting plate 11, which is sleeved on the heating element 13. A second thermostat 20 is also installed on the mounting shell to measure the temperature inside the mounting cavity, so as to prevent the temperature from rising when the blower assembly is not working, which would affect the service life of the plastic casing. Both the first thermostat 10 and the second thermostat 20 are connected to the fuse assembly 14, which serves to protect the heating element 13 from overheating. The fuse assembly 14 is a fuse, a temperature protector, or a thermal fuse. Thermal fuses include, but are not limited to, various types such as square, cylindrical, ceramic shell, and metal shell. The installation design of the thermostat ensures timely temperature measurement and control. The thermostats include, but are not limited to, ceramic shell thermostats, metal shell thermostats, plastic shell thermostats, snap-action thermostats, thermocouples, etc., without occupying extra space, which can optimize the overall design size. The heat sink 12 is an aluminum sheet with good heat dissipation. The surface of the aluminum sheet can be sprayed or not coated, and it is easy to form and process. Furthermore, the heating element assembly 1 can be designed to have one or more heating tubes 13. The shape of the heating tube 13 includes, but is not limited to, straight and circular shapes. There are one or more thermostats. The fuse assembly 14 is equipped with one or more thermostats. The cross-sectional shape of the heat sink 12 includes, but is not limited to, rectangular, square, circular, irregular, and wavy shapes. The overall shape of the heat sink 12 is planar, wavy, or U-shaped with both sides bent. The heat sink 12 is arranged at a certain interval and then cold-pressed together with the heating tube 13. The mounting plate 11 is also assembled together with the heating tube 13 by cold pressing. The material of the heating tube 13 is stainless steel, iron, or aluminum.

[0047] In this utility model device, the assembly and coordination of various components, such as the impeller, motor, fan 4, heating element 13, and first temperature controller 10, are existing technologies or materials. The relevant technical personnel can directly purchase or order them from the market according to the required product model and specifications.

[0048] All electrical components mentioned in the text are connected to an external main controller and 220V AC mains power or industrial power. The main controller can be a conventional known device such as a computer that plays a control role.
