Description

Mold device for integral heat exchange pipe and integral heat exchange pipe manufactured using the same

[0001] The present invention relates to a mold device for an integral heat exchange pipe and an integral heat exchange pipe manufactured using the same, and more particularly, to a mold device for an integral heat exchange pipe for integrally extruding a heat exchange pipe and an integral heat exchange pipe manufactured using the same.

[0002] Typically, in a refrigeration cycle, refrigerant circulates through a compressor, condenser, expansion valve, and evaporator. Heat exchange occurs between the subcooled, low-pressure, cold refrigerant exiting the evaporator and the high-pressure, warm refrigerant entering the expansion valve from the condenser. This lowers the temperature of the refrigerant entering the evaporator, thereby improving cooling performance. To achieve this refrigerant heat exchange, double-pipe systems are used in refrigeration piping systems.

[0003] In addition, among heat exchangers, the fin pipe type heat exchanger and the cooling and heating heat exchanger using the radiating fin cause a cooling effect when the heat of the fluid passing through the inside of the fin pipe type heat exchanger is radiated into the air or liquid through the external radiating fin, and when the heat exchange is increased through the radiating fin to the guide hole and the heat is absorbed, the fluid is rapidly heated to perform heat exchange, and is a device widely used in effective condensers or evaporators of air conditioners such as refrigerators or air conditioners, radiators of automobiles, rapid heaters, and heat sinks for cooling electronic components.

[0004] Among these, heat exchangers that are formed by pre-processing and drawing a fin pipe type heat exchanger to form a heat dissipation fin as an integral part have high heat transfer efficiency and are mainly used in evaporation units for air conditioners, radiators, and dehumidifiers.

[0005] However, the heat exchanger in which the heat dissipation fins are integrally formed is such that when the fluid passes through the inside of the fin pipe type heat exchanger, the liquid or gaseous fluid does not evenly contact the inner surface of the fin pipe type heat exchanger by 100% or more to exchange heat, and instead, some of the fluid passes quickly to the center of the tube as is, which reduces heat transfer with the external heat dissipation fins. This can be seen as the biggest problem in the heat exchange of existing fluids and heat exchangers for fin pipes.

[0006] That is, in general, when there is no device inside the fluid heat exchanger that causes the fluid to vortex periodically, some of the heat remaining on the surface of the fluid is well transferred to the fin pipe type heat exchanger, but the heat in the inner center of the oil is not well transferred, which has limitations in increasing the heat transfer efficiency.

[0007] In addition, the capillary tube of this heat exchanger is widely used in small-capacity electric refrigerators, room air conditioners, car air conditioners, showcases, etc. When considering the efficiency of the refrigeration device, it is better to constantly adjust the manual expansion valve or use a thermostatic automatic expansion valve, but in small-capacity refrigeration devices, the capillary tube is widely used in terms of cost, and it is also the simplest in structure, so there are few parts to fail, and during compressor stop, the high-pressure and low-pressure parts are pressure balanced through the capillary tube, making it easy to start the compressor.

[0008] Recently, attempts have been made to replace copper in terms of material diversification, and aluminum is the metal that is the most abundant among the elements that make up the Earth's crust, and not only does it have excellent properties such as processability, lightness, and conductivity, but it is also easy to alloy with other metals and can have various material properties depending on the composition of the alloying elements, so it is attracting attention as a material to replace copper capillaries.

[0009] However, when aluminum alloy is used to manufacture capillaries through an extrusion process using a hot working method, the characteristics and corrosion resistance of the aluminum alloy can be maintained, but the diameter of the capillary is small, so the extrusion rate decreases due to a low extrusion ratio, making it impossible to manufacture capillaries or requiring additional processes, which increases manufacturing costs.

[0010] In particular, for aluminum capillaries to replace copper, the aluminum alloy must maintain properties such as corrosion resistance even after being processed into aluminum capillaries. Therefore, optimization of the process is required to manufacture capillaries that meet the design diameter specifications while maintaining the raw material properties and corrosion resistance of the aluminum alloy.

[0011] As a prior art for solving this problem, there is Patent Publication No. 10-2021-0016847, but the prior art does not solve the problem of joining because it uses aluminum capillaries with different inner diameters by simultaneously extruding them and independently compressing them to join multiple aluminum capillaries with different inner diameters.

[0012] The present invention has been devised to solve the above-mentioned conventional problems, and the purpose of the present invention is to provide a molding device for a heat exchange integral pipe, which comprises a first mold part for extruding the outer surface of a heat exchange double pipe, a second mold part, and a third mold part for extruding the inner surface of the heat exchange double pipe, thereby extruding the heat exchange double pipe as a single piece, thereby facilitating the extrusion process of the heat exchange integral pipe, reducing the weight of the pipe, and improving the productivity and marketability of the pipe, and a heat exchange integral pipe manufactured using the same.

[0013] In addition, the present invention provides a mold device for a heat exchange integral pipe, which can minimize extrusion deformation of the outer portion of a pipe during extrusion of a double pipe of a heat exchange integral pipe and reduce extrusion defects by having a first mold as a first mold part and a first extrusion hole and a first installation hole in multiple stages, and a heat exchange integral pipe manufactured using the mold device.

[0014] In addition, the present invention provides a mold device for a heat exchange integral pipe, which can improve the extrusion performance of the pipe by gradually reducing and gradually expanding the double pipe of the heat exchange integral pipe by extruding the outer portion of the pipe in multiple stages and having an 11th extrusion hole, a 12th extrusion hole, a 13th extrusion hole, a 14th extrusion hole, a 15th extrusion hole, and a 16th extrusion hole as the first extrusion holes in multiple stages, and a heat exchange integral pipe manufactured using the same.

[0016] In addition, the present invention also provides a mold device for an integrated heat exchange pipe, which can improve heat exchange performance by extruding the first and second pipes of the integrated heat exchange pipe together as an integral part, thereby reducing the manufacturing cost and manufacturing time of the heat exchange double pipe by applying the double pipe of the integrated heat exchange pipe to various heat exchange facilities, thereby improving the manufacturing performance of the heat exchange facility, and an integrated heat exchange pipe manufactured using the same.
