Description

Technical Field

[0001] This utility model relates to the field of electric heater technology, and in particular to a direct-flow electric heating cast aluminum heater. Background Technology

[0002] To quickly obtain hot water, people generally use heating devices such as water heaters and electric water faucets. These devices all require an electric heating source. Commonly used electric heating sources include electric heating rods, PTC heaters, electric heating films, and integral cast aluminum heaters. Among them, integral cast aluminum heaters are widely popular due to their low production cost, ease of use, and fast heating. Most cast aluminum heaters on the market use coiled pipes or multiple pipes and water circuits, resulting in limited water flow. If a larger flow is required, the pipe diameter must be increased, leading to increased costs. In addition, the spiral coiled pipes are prone to blockage after prolonged use, resulting in a poor user experience. Utility Model Content

Moreover, it is direct-flow and will not be blocked, thus overcoming the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a straight-through electric heating cast aluminum heater, comprising a water pipe, a cast aluminum heating component, and a retaining ring, characterized in that the water pipe is wrapped by the cast aluminum heating component, the cast aluminum heating component is set in an arc shape, its inner arc is fitted and adapted to the water pipe, the outer arc diameter of the cast aluminum heating component is equal, and multiple cast aluminum heating components are spliced ​​to form a cylindrical heater; mounting platforms are set at both ends of the cast aluminum heating component, the heating rod of the cast aluminum heating component passes through the cast aluminum longitudinally and protrudes from the mounting platform, the cast aluminum heating component is fitted to the water pipe, the mounting platforms are connected to form a smooth surface, the retaining ring is set on the smooth surface, the inner ring of the retaining ring is fitted and adapted to the heating rod, and the inner surface of the retaining ring is fitted to the smooth surface of the mounting platform.

[0005] Furthermore, it also includes a housing, the housing being provided with a C-shaped slot, the retaining ring being provided with a second screw hole, the number of the C-shaped slot and the second screw hole being the same and compatible, and the retaining ring being fixed together with the housing by screws.

[0006] Furthermore, the retaining ring is also provided with a flange, and a third screw hole is provided on the flange. The cast aluminum heater is fixed to the water heater or other equipment that requires hot water through the third screw hole.

[0007] Furthermore, the cast aluminum heating assembly is formed by die casting at least two of the heating rods.

[0008] The above technical solution has the following beneficial effects:

[0009] This utility model provides a direct-flow electric heating cast aluminum heater, which consists of water pipes and multiple sets of cast aluminum heating components. When the power is turned on, the heating rods work, the cast aluminum heating components heat up at high speed, and the water in the water pipes is heated quickly. Because it is a direct-flow type, it saves costs and will not clog. It can also provide hot water quickly and continuously. It has high thermal efficiency, simple structure, and is sturdy and durable, making it very popular. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] See Figures 1-5 As shown, this utility model discloses a straight-through electric heating cast aluminum heater, including a water pipe 1, a cast aluminum heating component 2, and a retaining ring 3. The water pipe 1 is wrapped by at least two cast aluminum heating components 2. This utility model provides six cast aluminum heating components 2, each cast aluminum heating component 2 being arc-shaped, with its inner arc fitting and matching the water pipe 1. The outer arc diameters of the cast aluminum heating components 2 are equal, and multiple cast aluminum heating components 2 are spliced ​​together to form a cylindrical heater. Installation platforms 21 are provided at both ends of the cast aluminum heating components 2. The heating rods of the cast aluminum heating components 2 longitudinally pass through the cast aluminum body and protrude from the installation platforms. Heating rods 22 are provided on the installation platforms. The cast aluminum heating components 2 are fitted to the water pipe 1 and fixed by a retaining ring. The installation platforms 21 are thus connected to form a smooth surface. The retaining ring 3 is placed on the smooth surface, with its inner ring fitting and matching the heating rod 22. The inner surface of the retaining ring 3 is fitted to the smooth surface of the installation platform.

[0020] A straight-through electric heating cast aluminum heater further includes a housing 4, the housing 4 being provided with a C-shaped slot 41, and the retaining ring 3 being provided with a second screw hole 31. The number of C-shaped slots and the second screw hole are the same and they are compatible, and the retaining ring can be fixed together with the housing by screws.

[0021] The retaining ring 3 is also provided with a flange 32, and a third screw hole 321 is provided on the flange. The cast aluminum heater is fixed to the water heater or other equipment that requires hot water through the third screw hole.

[0022] The cast aluminum heating assembly 2 is formed by die casting at least two of the aforementioned heating rods.

[0023] After the power is turned on, the heating element starts working, and the cast aluminum heating element 2 heats up at high speed, quickly heating the water in the pipe. Because it is a straight-through type, the flow rate does not need to be considered by increasing the pipe diameter as with spiral heaters, thus saving costs. It will not clog and can provide hot water quickly and continuously. It has high thermal efficiency, simple structure, and is sturdy and durable, providing a better user experience.

[0024] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and alterations to these embodiments without departing from the principles and spirit of this utility model will still fall within the protection scope of this utility model.
