Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchangers, in particular to a novel aluminum phase-change heat exchanger. Background Art

[0002] A heat exchanger, also known as a heat exchanger, is a device that transfers some of the heat from a hot fluid to a cold fluid. Heat exchangers play a vital role in chemical, petroleum, power, food, and many other industrial processes. In chemical production, they serve as heaters, coolers, condensers, evaporators, and reboilers, enjoying widespread applications. For example, a low-temperature polytetrafluoroethylene heat exchanger for power plants is a novel device used to reduce exhaust gas temperatures and recover waste heat. The use of fluoroplastic heat exchangers prevents acid corrosion and reduces flue gas temperatures to below 100°C.

[0003] The original throttling refrigerant phase change heat exchanger uses copper tubes as the refrigerant flow channel. The aluminum radiator is assembled and pressed into two halves, so that the copper tube is in contact with the aluminum plate. The refrigerant takes away the heat along a certain direction through the inner wall of the copper tube flow channel, thereby reducing the heat of the electrical heating element.

[0004] However, the thermal conductivity of aluminum is better than that of copper, but using copper tubes as flow channels has no cost advantage under the fierce market competition. Based on this, a new type of aluminum phase change heat exchanger is designed. Utility Model Content

[0005] The purpose of the present invention is to provide a novel aluminum phase-change heat exchanger to solve the problems raised in the above background technology.

[0006] The technical solutions adopted in this utility model are as follows:

[0007] A novel aluminum phase-change heat exchanger includes a heat exchange plate. A flow channel is provided in the heat exchange plate. The flow channel is spirally distributed in the heat exchange plate. An inlet joint is provided at the flow channel inlet, and an outlet joint is provided at the flow channel outlet.

[0008] Preferably, the heat exchange plate and the flow channel adopt an integrated molding structure.

[0009] Preferably, the heat exchange plate includes a heat exchange plate body, the flow channel is opened at the top of the heat exchange plate body, and a cover plate is provided on the top of the heat exchange plate body.

[0010] Preferably, the inlet connector is connected to a filter and a throttle valve in sequence.

[0011] Preferably, the liquid inlet of the filter is connected to the throttle valve, and the liquid outlet of the filter is connected to the inlet joint.

[0012] Preferably, a filter body is provided at one end of the filter close to the liquid inlet. The filter body is cylindrical in structure, and a port thereof is provided between the filter front cover and the filter body.

[0013] Preferably, several layers of annular filter screens are provided inside the filter screen body.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0015] In the utility model, the flow channel is directly opened on the heat exchange plate, and the use of copper tubes as the flow channel is eliminated, thereby improving heat exchange efficiency. At the same time, it can effectively reduce material and manufacturing costs, promote energy conservation and emission reduction and sustainable development, and through the design of the filter, it can effectively avoid flow channel blockage and flow reduction caused by long-term use, and is more practical.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] Example:

[0033] A new type of aluminum phase change heat exchanger, such as Figure 1-4 As shown, it includes a heat exchange plate 1, a flow channel 2 is opened in the heat exchange plate 1, the flow channel 2 is spirally distributed in the heat exchange plate 1, an inlet joint 3 is provided at the inlet of the flow channel 2, and an outlet joint is provided at the outlet of the flow channel 2.

[0034] Furthermore, the flow channel 2 includes a plurality of channels arranged in parallel, and adjacent channels are connected end to end, thereby covering the interior of the heat exchange plate 1 .

[0035] In a possible embodiment, the heat exchange plate 1 and the flow channel 2 adopt an integrated molding structure. In this case, the heat exchange plate 1 is an aluminum plate, and the flow channel 2 is designed as an aluminum tube.

[0036] In one possible embodiment, the heat exchange plate 1 includes a heat exchange plate body, a flow channel 2 is opened on the top of the heat exchange plate body, and a cover plate is provided on the top of the heat exchange plate body. At this time, the heat exchange plate body is an aluminum plate, the flow channel 2 is opened above the aluminum plate, and then covered with an aluminum cover plate and welded by a brazing process.

[0037] In a possible embodiment, a filter 5 and a throttle valve 6 are sequentially connected to the inlet connector 3 .

[0038] In a possible implementation manner, the liquid inlet 53 of the filter 5 is connected to the throttle valve 6 , and the liquid outlet 54 of the filter 5 is connected to the inlet connector 3 .

[0039] In a possible embodiment, a filter body 51 is provided at one end of the filter 5 close to the liquid inlet 53 . The filter body 51 has a cylindrical structure, and its port is provided between the front cover of the filter 5 and the body of the filter 5 .

[0040] In a possible embodiment, a plurality of layers of annular filter screens 52 are provided inside the filter screen body 51 .

[0041] Furthermore, in order to prevent the flow channel 2 from being blocked, the present application designs a filter screen that can filter impurities such as coolant. The filter holes of a single cup-shaped filter cartridge are easily blocked by impurities. The present application designs multiple annular filter screens 52 that can perform preliminary filtering on part of the liquid and intercept some impurities, thereby reducing the probability of blockage of the filter holes of the filter screen body 51 and being more practical.

[0042] By adopting the above technical solutions:

[0043] The design and process of the new structure are suitable for medium and large-scale production processes. They not only meet customer or market needs, but also ensure welding quality and reduce material costs by 30% to 45%, making the product more competitive in the market. After testing, the product performance and energy efficiency have not been reduced. Since the aluminum body is directly used as the refrigerant flow channel, its cooling speed is increased by 5% to 10 and the cooling temperature is reduced by 10% to 18%, thereby improving the heat exchange energy efficiency conversion and achieving the expected effect.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
