Description

Technical Field

[0001] The invention relates to the field of heat dissipation, in particular to the heat dissipation of high-power electronic equipment and the heat dissipation of air conditioners. Background Art

[0002] A heat pipe is a highly efficient radiator that uses the phase change process of a liquid medium evaporating at the hot end and condensing at the cold end to quickly conduct heat. The inside of the heat pipe is pumped into a negative pressure state and filled with an appropriate liquid. This liquid has a low boiling point and is easy to evaporate. There is a liquid wick inside the heat pipe, which is made of a capillary porous material. One end of the heat pipe is the evaporation end, and the other end is the condensation end. When one end of the heat pipe is heated, the liquid in the capillary tube quickly vaporizes, and the vapor flows to the other end under the power of heat diffusion, and condenses at the cold end to release heat. The liquid then flows back to the evaporation end along the porous material by capillary action, and the cycle continues until the temperatures at both ends of the heat pipe are equal, at which time the steam heat diffusion stops.

[0003] Air conditioning is also a radiator with vapor-liquid phase change. The evaporator and condenser are mainly composed of air conditioning pipes. The compressor compresses the refrigerant in the air conditioning pipe from gas to liquid. After cooling through the condenser, it is depressurized and cooled through the expansion valve. Then, in the evaporator, the liquid evaporates and absorbs heat to become gas, and then enters the compressor cycle. After the refrigerant is depressurized by the expansion valve, the temperature drops to more than 20 degrees below zero. Condensed water is easily generated on the surface of the air conditioning pipe and the heat sink, which wastes cooling capacity and brings drainage troubles. At the same time, the temperature of the air outlet is too low, and the cold wind blows directly on the human body, which makes people feel uncomfortable. Air conditioning heating is a process of reverse circulation of refrigerant. When the outdoor temperature is too low, the refrigerant cannot evaporate from liquid to gas, and the vapor-liquid cycle fails. Therefore, an electric auxiliary heater needs to be installed.

[0004] The automobile engine water-cooled radiator is an excellent radiator, which consists of a radiator core and a water chamber for cooling. The coolant flows in the radiator core, and the air flows through the radiator core at high speed. The coolant and the air exchange heat through the radiator core. The tube-belt radiator is made of corrugated heat-dissipating belts and heat-dissipating tubes arranged alternately and welded. Compared with the tube-fin radiator, the tube-belt radiator can increase the heat dissipation area by about 12% under the same conditions. In addition, the heat-dissipating belt has holes similar to shutters to disturb the airflow, so as to destroy the adhesion layer of the flowing air on the surface of the heat-dissipating belt and improve the heat dissipation capacity.

[0005] Application 201910436719.2 proposes an electric heating heat exchange structure, which consists of a tube-belt radiator and an electric heating core. The tube-belt radiator adopts the structure of the automobile engine water-cooled radiator without the water chamber, and includes a main plate, a heat dissipation belt, a flat tube and a side plate. The electric heating core is a heat source and is inserted and installed in the flat tube. The use of this heat exchange structure can increase the heat dissipation area and improve the heat dissipation efficiency. The disadvantage of this technical solution is that the electric heating core is not very convenient to install. Summary of the invention

[0006] In order to alleviate the deficiencies of the prior art, the present invention proposes the following solutions.

[0007] The technical solution adopted by the present invention to solve its technical problem is: A tube-belt heat dissipation device includes a tube-belt heat sink and a heat source component proposed in application 201910436719.2. The tube-belt heat sink includes a flat tube and a heat dissipation belt. The heat source component is installed in the flat tube. The side of the flat tube is open, and the heat source component is inserted and installed from the side of the flat tube. The flat tube that does not need to be installed with the heat source part can be flattened or replaced with a thinner aluminum plate, so that the air duct space occupied by the flat tube is smaller. The tube-belt heat sink is made using a flat tube with an unclosed cross-section, or the side of the flat tube of the tube-belt heat sink is broken so that the side of the flat tube is open.

[0008] The beneficial effects of the present invention are: A tube-belt heat dissipation device includes a tube-belt heat sink and a heat source component proposed in application 201910436719.2. The tube-belt heat sink includes a flat tube and a heat dissipation belt. The heat source component is installed in the flat tube. The side of the flat tube is open. The heat source component is inserted and installed from the side of the flat tube, which makes installation more convenient and is conducive to making heat dissipation devices of various shapes. The flat tube that does not need to install the heat source part can be flattened or replaced with a thinner aluminum plate, so that the air duct space occupied by the flat tube is smaller, which is conducive to increasing the heat dissipation area. The tube-belt heat sink is made using a flat tube with an unclosed cross section, or the side of the flat tube of the tube-belt heat sink is broken, so that the side of the flat tube is opened. The tube-belt heat sink is made using a flat tube with an unclosed cross section, which can save the process of breaking the side of the flat tube, and the production cost is relatively low; and the side of the flat tube of the tube-belt heat sink is broken, and the size of the opening can be controlled according to the needs, so that the flat tube can maintain a certain strength.

[0009] A tube-belt heat dissipation device includes a tube-belt heat sink and a heat source component proposed in application 201910436719.2, wherein the tube-belt heat sink includes a flat tube and a heat dissipation belt, and the heat source component is installed in the flat tube. The heat source component is mainly composed of a heat pipe, the condensation end of the heat pipe is installed in the flat tube of the tube-belt heat sink, and the evaporation end of the heat pipe is installed on the base of the heat dissipation device, and contacts with heat sources such as chips. The condensation end of the heat pipe can be flattened, so that the contact area between the heat pipe and the flat tube is increased to improve the heat dissipation efficiency, and at the same time, the air duct space occupied by the flat tube is smaller. The flat tube that does not need to be installed with the heat source part can be flattened, or replaced with a thinner aluminum plate, further making the air duct space occupied by the flat tube smaller. The side of the flat tube can be opened, and the heat source component is inserted and installed from the side of the flat tube, making the installation more convenient and facilitating the manufacture of radiators of various shapes. The tube-belt heat sink is made using a flat tube with an unclosed cross section, or the side of the flat tube of the tube-belt heat sink is broken, so that the side of the flat tube is opened.

[0010] The beneficial effects of the present invention are: A tube-belt heat dissipation device includes a tube-belt heat sink and a heat source component proposed in application 201910436719.2. The tube-belt heat sink includes a flat tube and a heat dissipation belt, and the heat source component is installed in the flat tube. The heat source component is mainly composed of a heat pipe, and the condensation end of the heat pipe is installed in the flat tube of the tube-belt heat sink, so that the heat can be diffused to the heat dissipation belt to obtain a larger heat dissipation area. The turbulent structure of the heat dissipation belt can also be used to effectively improve the heat dissipation efficiency. The evaporation end of the heat pipe is installed on the base of the heat dissipation device and contacts with a heat source such as a chip, and the heat pipe can be used to quickly transfer heat. The condensation end of the heat pipe can be flattened, so that the air duct space occupied by the flat tube is smaller. The flat tube that does not need to be installed with the heat source part can be flattened or replaced with a thinner aluminum plate, which further makes the air duct space occupied by the flat tube smaller, which is conducive to increasing the heat dissipation area and improving the heat dissipation efficiency. The side of the flat tube can be opened, and the heat pipe is inserted and installed from the side of the flat tube, making the installation more convenient. At the same time, the heat pipe can be bent and installed, which is conducive to making heat dissipation devices of various shapes. The tube-belt radiator is made by using a flat tube with an open cross section, or the side of the flat tube of the tube-belt radiator is broken to make the side of the flat tube open. The process of breaking the side of the flat tube can be omitted when making the tube-belt radiator with a flat tube with an open cross section, and the production cost is relatively low; and by breaking the side of the flat tube of the tube-belt radiator, the size of the opening can be controlled according to needs, so that the flat tube can maintain a certain strength.

[0011] A tube-belt heat dissipation device includes a tube-belt heat sink and a heat source component proposed in application 201910436719.2. The tube-belt heat sink includes a flat tube and a heat sink. The heat source component is installed in the flat tube. The heat source component includes an air conditioning tube, an electric heating core, etc. The air conditioning tube is a pipeline of the condenser and / or evaporator of the air conditioner. The air conditioning tube and the electric heating core are installed alternately, respectively in different flat tubes, or in the same flat tube. When electric auxiliary heating is not required, only the air conditioning tube can be installed without the electric heating core. The air conditioning tube can be flattened, so that the contact area between the air conditioning tube and the flat tube is increased to improve the heat dissipation efficiency, and at the same time, the air duct space occupied by the flat tube is smaller. The flat tube that does not need to be installed with the heat source part can be flattened, or replaced with a thinner aluminum plate, further making the air duct space occupied by the flat tube smaller. The side of the flat tube can be opened, and the heat source component is inserted and installed from the side of the flat tube. The tube-belt heat sink is made using a flat tube with an unclosed cross section, or the side of the flat tube of the tube-belt heat sink is broken, so that the side of the flat tube is opened. Air conditioning pipes are generally copper or aluminum pipes with a high melting point. The flat pipes can be inserted first and then the heat dissipation belts can be welded. The flat pipes after the evaporator air conditioning pipes are sealed to prevent the air flowing through the evaporator from contacting the evaporator air conditioning pipes and generating condensed water. Furthermore, the surface temperature of the flat pipes can be controlled by adjusting the contact area between the air conditioning pipes and the flat pipes to avoid or reduce the generation of condensed water on the heat dissipation belts.

[0012] The beneficial effects of the present invention are: A tube-belt heat dissipation device includes a tube-belt heat sink and a heat source component proposed in application 201910436719.2. The tube-belt heat sink includes a flat tube and a heat dissipation belt. The heat source component is installed in the flat tube. The heat source component includes an air conditioning tube, an electric heating core, etc. The air conditioning tube is a pipeline of a condenser and / or an evaporator of an air conditioner. The air conditioning tube is installed in the flat tube of the tube-belt heat sink, so that the heat can be diffused to the heat dissipation belt to obtain a larger heat dissipation area. The turbulent structure of the heat dissipation belt can also be used to effectively improve the heat dissipation efficiency. The air conditioning tube and the electric heating core are installed alternately, respectively in different flat tubes, or in the same flat tube. When electric auxiliary heating is not required, only the air conditioning tube can be installed without the electric heating core. This structure can make the air conditioning tube and the electric heating core reuse the heat dissipation structure, which is conducive to saving space and reducing costs; when the ambient temperature is too low, the electric heating core can promote the evaporation of the refrigerant in the adjacent air conditioning tube, and can also avoid and eliminate ice on the heat dissipation belt, thereby improving the efficiency of the compressor. The air conditioning pipe can be flattened, so that the contact area between the air conditioning pipe and the flat pipe is increased to improve the heat dissipation efficiency, and at the same time, the air duct space occupied by the flat pipe is smaller. The flat pipe that does not need to install the heat source part can be flattened, or replaced with a thinner aluminum plate, which further makes the air duct space occupied by the flat pipe smaller, which is conducive to increasing the heat dissipation area and improving the heat dissipation efficiency. The side of the flat pipe can be opened, and the heat source component is inserted and installed from the side of the flat pipe, making the installation more convenient. At the same time, the air conditioning pipe can be bent and installed, which is conducive to making heat dissipation equipment of various shapes. Use a flat tube with an unclosed cross section to make a tube-belt radiator, or break the side of the flat tube of the tube-belt radiator to make the side of the flat tube open. Using a flat tube with an unclosed cross section to make a tube-belt radiator can save the process of breaking the side of the flat tube, and the production cost is relatively low; and breaking the side of the flat tube of the tube-belt radiator can control the size of the opening according to needs, so that the flat tube can maintain a certain strength. Air conditioning pipes are generally copper pipes or aluminum pipes with high melting points. The air conditioning pipes can be inserted into the flat pipes first and then welded to the heat dissipation belts. This can improve the firmness of the contact between the air conditioning pipes and the flat pipes and make installation easier. The flat pipes behind the evaporator air conditioning pipes are closed to prevent the air flowing through the evaporator from contacting the evaporator air conditioning pipes and generating condensed water. Furthermore, the surface temperature of the flat pipes is controlled by adjusting the contact area between the air conditioning pipes and the flat pipes to avoid or reduce the generation of condensed water on the heat dissipation belts. This structure can reduce the waste of cooling capacity, reduce energy consumption, and avoid the discomfort caused by the cold air blowing directly on the human body due to the low temperature of the air outlet, thereby improving comfort.
