Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and more specifically, to a radiator. Background Technology

[0002] In southern my country, especially in the Yangtze and Huaihe River basins, where summers are hot and winters are cold, centralized heating cannot be successfully implemented due to the limitations of building types and climate. This results in low comfort levels and high costs for individual household heating.

[0003] In northern my country, due to the limitations of centralized heating, such as long construction period, huge investment and many heating links, most areas still do not adopt centralized heating, and most towns and rural areas still rely on self-heating.

[0004] Clean heating refers to heating methods that achieve low emissions and low energy consumption through high-efficiency energy-using systems. However, both underfloor heating and air source heat pumps require continuous operation of water pumps to circulate the heat transfer medium. To ensure sufficient heating, the temperature of the heat transfer medium typically needs to vary depending on the heating area. Larger heating areas require longer circulation cycles and higher temperatures to complete circulation, while smaller areas require water temperatures determined by the pump's circulation cycle. Regardless of the size of the heating area or the length of the circulation cycle, existing heating systems suffer from the following problems:

[0005] 1. The water pump runs continuously, resulting in high noise and high power consumption;

[0006] 2. Excessive heat transfer fluid temperature can easily cause burns;

[0007] 3. Low thermal efficiency;

[0008] While using air conditioning for heating can avoid the above problems, the following issues still exist:

[0009] 1. The strong wind is uncomfortable;

[0010] 2. Strong winds can easily generate dust indoors, causing health problems;

[0011] To address the aforementioned technical problems, we provide a radiator that optimizes existing air conditioners to solve these issues. Utility Model Content

[0012] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0013] To at least partially solve the above problems, this utility model provides a radiator, including: a heat exchange component, an upper main pipe, a lower main pipe, and a heat dissipation component. The heat exchange component is disposed inside the lower main pipe, and the length L of the heat exchange component is less than the length of the lower main pipe. The heat dissipation component has a flow channel for the flow of heat carrier. The heat dissipation component is connected to the upper main pipe and the lower main pipe. A connecting hole is provided at the connection between the heat dissipation component and the upper main pipe, and at the connection between the heat dissipation component and the lower main pipe. The upper main pipe and the lower main pipe are connected to the flow channel inside the heat dissipation component through the connecting hole.

[0014] Preferably, the length L of the heat exchanger is not greater than 70% of the length of the lower main pipe.

[0015] Preferably, there are at least two heat sinks, which are arranged at equal intervals to form a heat sink, and each heat sink is connected to the upper main pipe and the lower main pipe.

[0016] Preferably, the number of heat sinks is not less than two.

[0017] Preferably, the heat carrier is water.

[0018] Preferably, the heat sink is a heat pipe.

[0019] Preferably, the upper main pipe, the lower main pipe, and the heat sink are all filled with heat carrier.

[0020] Preferably, the inner and outer surfaces of the upper main pipe, lower main pipe, and heat sink are all coated with electrostatic powder coating.

[0021] Preferably, the main pipe is provided with a water inlet.

[0022] Preferably, the heat exchanger is welded to the lower manifold.

[0023] Compared with the prior art, the present invention has at least the following beneficial effects:

[0024] Some split air conditioners include both an outdoor and indoor unit. Because the heat exchange and heat dissipation components are integrated, this radiator occupies less space, is easy to install, and offers flexible layout. Therefore, this radiator can be directly used with existing split air conditioners. The low-pressure working fluid (such as Freon) absorbs heat from the outside and vaporizes. It is then compressed by the compressor in the outdoor unit into a high-temperature, high-pressure gas, which exchanges heat with a heat carrier (such as water) through the heat exchange components within the radiator. Because the temperature of the heat carrier after heat exchange is typically 40-50℃, low-temperature heating can be achieved, ensuring high safety and preventing burns. This radiator heats indoor air through thermal radiation and convection, eliminating the feeling of drafts and reducing discomfort from dry, hot air, resulting in a healthy and comfortable indoor environment.

[0025] This radiator features a sealed design with natural heat circulation. Compared to underfloor heating, it eliminates the need for a water pump, consumes less energy, and boasts extremely high thermal efficiency. By integrating this radiator into an existing split-type air conditioning system, it can provide comfortable heating in winter without affecting cooling in summer. Furthermore, when used in conjunction with existing split-type air conditioners, the modification is simple, installation is convenient, equipment utilization is high, and operating costs are low, effectively solving winter heating problems in parts of northern China and most of southern China.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0035] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0036] like Figures 1-5As shown, this utility model provides a radiator, including: a heat exchanger 1, an upper main pipe 2, a lower main pipe 3, and a heat dissipation component 4. The heat exchanger 1 is disposed inside the lower main pipe 3. The length L of the heat exchanger 1 is less than the length of the lower main pipe 3. Typically, the length L of the heat exchanger 1 is no more than 70% of the length of the lower main pipe 3. Specifically, the length L of the heat exchanger 1 in this utility model is not the length of a bent heat exchanger after straightening. The heat exchanger 1 is an air conditioner condenser. The heat dissipation component 4 has a flow channel for the heat carrier to circulate. Typically, a heat dissipation pipe can be used as the heat dissipation component 4, or any commercially available product or existing technology with a flow channel capable of heat radiation. The heat dissipation component 4 is connected to the upper main pipe 2 and the lower main pipe 3. A connecting hole 5 is provided at the connection points between the heat dissipation component 4 and the upper main pipe 2, and at the connection points between the heat dissipation component 4 and the lower main pipe 3. Both the upper main pipe 2 and the lower main pipe 3 are connected to the flow channel inside the heat dissipation component 4 through the connecting hole 5.

[0037] Furthermore, the number of heat sinks 4 is not less than two, and the multiple heat sinks 4 are arranged at equal intervals to form a heat dissipation duct. Each heat sink 4 of the heat dissipation duct is connected to the upper main pipe 2 and the lower main pipe 3. Typically, the number of heat dissipation ducts is not less than two.

[0038] To ensure adequate circulation of the heat carrier within the radiator, the upper main pipe 2, lower main pipe 3, and heat sink 4 are typically filled with heat carrier, usually water. For ease of filling, a water inlet 6 is usually provided on the upper main pipe 2. The inner and outer surfaces of the upper main pipe 2, lower main pipe 3, and heat sink 4 are all coated with electrostatic powder coating.

[0039] The heat exchanger 1 is located inside the lower main pipe 3. The heat exchanger 1 consists of a straight pipe and a spiral pipe that is spirally wound around the straight pipe with the straight pipe as the central axis. One end of the spiral pipe is the working fluid inlet 7, which extends to the outside of the lower main pipe 3. The spiral pipe is located inside the lower main pipe 3, and the end away from the working fluid inlet 7 is connected to one end of the straight pipe. The other end of the straight pipe is the working fluid outlet 8, which extends to the outside of the lower main pipe. Usually, the connection between the outer wall of the working fluid inlet 7 and the lower main pipe 3, and the connection between the outer wall of the working fluid outlet 8 and the lower main pipe 3, are made by welding.

[0040] The working principle and beneficial effects of the above technical solution are as follows: The heat exchanger 1 inside the lower main pipe 3 transfers heat to the heat carrier near the heat exchanger 1, causing the temperature of the heat carrier to rise. The heat carrier with a higher temperature has a lower density and flows upward, passing through the upper main pipe 2, the heat dissipation component 4 connected to the upper main pipe 2, and the heat dissipation component 4 connected to the lower main pipe 3. During the flow, the heat carrier with a higher temperature radiates heat through the outer surfaces of the upper main pipe 2, the lower main pipe 3, and the heat dissipation component 4. The heat carrier with a higher density after heat dissipation flows downward, and after converging through the lower main pipe 3, it flows through the heat exchanger 1. This process is repeated to form a circulating flow of the heat carrier.

[0041] Existing split air conditioners consist of an outdoor unit and an indoor unit. Because the heat exchanger 1 and the heat dissipation component 4 are integrated into one unit, this radiator occupies less space, is easy to install, and offers flexible layout. Therefore, this radiator can be directly used with existing split air conditioners. The low-pressure working fluid (e.g., Freon) absorbs heat from the outside and vaporizes. It is then compressed by the compressor in the outdoor unit into a high-temperature, high-pressure gas, which exchanges heat with a heat carrier (e.g., water) through the heat exchanger 1 within the radiator. Since the temperature of the heat carrier is typically 40-50℃ after heat exchange, low-temperature heating can be achieved, ensuring high safety and preventing burns. This radiator heats indoor air through thermal radiation and convection, eliminating the feeling of drafts and reducing discomfort from dry, hot air, resulting in a healthy and comfortable indoor environment.

[0042] This radiator features a sealed design with natural heat circulation. Compared to underfloor heating, it eliminates the need for a water pump, consumes less energy, and boasts extremely high thermal efficiency. By integrating this radiator into an existing split-type air conditioning system, it can provide comfortable heating in winter without affecting cooling in summer. Furthermore, when used in conjunction with existing split-type air conditioners, the modification is simple, installation is convenient, equipment utilization is high, and operating costs are low, effectively solving winter heating problems in parts of northern China and most of southern China.
