Description

Technical Field

[0001] The present invention belongs to the technical field of thermal management of ship equipment, and in particular, relates to a self-cleaning condensing compressor unit. Background Art

[0002] In ship environmental control equipment, condenser cleaning technology is a key link in the efficient operation of the condensing compressor unit. The conventional use of the equipment faces the complex conditions of ship operation turbulence and high temperature and high salt fog. As a result, after a period of use, dust, salt or other debris will accumulate on the condenser surface, causing the condenser to become dirty and blocked, the thermal resistance to increase, and the thermal management efficiency of the product to become lower. At the same time, salt will also continue to corrode the condenser fins and heat exchange tubes in the humid and hot marine environment, ultimately resulting in reduced product reliability and life.

[0003] There is no self-cleaning condensing compressor unit on the market. Traditional products usually use regular brushing or flushing to clean the surface of the condenser. Soft brushes are generally used for brushing, which is time-consuming and labor-intensive, and it is difficult to clean the salt stains on the surface of the condenser. For salt stains that are difficult to clean, if a hard steel brush is used for cleaning, it will damage the copper tube of the condenser; high-pressure water can effectively remove salt stains during flushing, but the water pressure must be controlled between 3Mpa and 4Mpa. Excessive water pressure will damage the internal parts of the equipment, and too little water pressure will result in poor cleaning effect. In addition, due to the internal space limitations of the product, brushing or flushing cannot thoroughly clean the inside of the condenser. The cleaning of the inside of the condenser can only be done by dismantling the condenser, but when it is installed again, it is easy to cause bump damage, poor sealing, and other problems, affecting the normal use of the condenser. Summary of the invention

[0004] Purpose of the Invention

[0005] In order to solve the above technical problems, the present invention provides an integrated self-cleaning device, which can effectively solve the problems that traditional condensing compressors cannot achieve rapid self-cleaning and regular brushing and cleaning are not thorough.

[0006] Technical Solution

[0007] A self-cleaning condensing compressor unit includes a condensing fan module, a condenser module, a frame module, a heat drive module, a pipeline module, a compressor module, a protective cover module and a flushing module. The condenser module is used to cool the refrigerant medium discharged from the pipeline module and the compressor module; the condensing fan module discharges the heat generated during the cooling process of the condenser module out of the product through a forced convection function; the condensing fan module, the condenser module, the heat drive module, the pipeline module, the compressor module, the protective cover module and the flushing module are all fixed on the frame module; the thermal drive module is used to control the start and stop and the speed of operation of the condensing fan module and the compressor module, and monitor the product operation status parameters in real time, thereby realizing the thermal management function of the product; the compressor module is used to force the refrigerant medium to flow; the protective cover module and the flushing module are used to self-clean the condenser module.

[0008] The protective cover module includes a first flushing valve, a spray plate, a diverter plate, a second flushing valve, a protective net, a protective cover shell, and a water collecting plate. A water collecting plate is welded to the upper end of the protective cover shell. The area where the water collecting plate is welded to the upper end of the protective cover shell forms a water collecting tank. The first flushing valve and the second flushing valve are respectively arranged on both sides of the water collecting tank. The spray plate is welded to the lower end of the water collecting plate and the inner side of the protective cover shell. The spray plate is an arc-shaped structure, and there are a number of spray holes on the spray plate. The spray range of the spray holes should be able to cover all areas inside the condenser module, so as to achieve thorough cleaning of the condenser module from the inside to the outside.

[0009] Furthermore, the first flush valve and the second flush valve are interconnected.

[0010] Furthermore, it also includes a diverter plate, which is arranged between the first flushing valve and the second flushing valve.

[0011] Furthermore, the spray holes arranged on the spray plate are divided into spray area A and spray area B by the protective cover shell and the water collecting plate.

[0012] Furthermore, the spraying area of ​​the spraying zone A should be larger than the area of ​​the spraying zone B.

[0013] Furthermore, the number of spray holes in the spray area A should be smaller than the number of spray holes in the spray area B.

[0014] Furthermore, the flushing module includes a three-way joint, a flushing hose, a first quick joint, and a second quick joint. One end of the three-way joint is connected to a high-pressure water source, and the other two ends are respectively connected to flushing hoses. One flushing hose is connected to the first quick joint, and the other flushing hose is connected to the second quick joint. The first quick joint is connected to a first flushing valve, and the second quick joint is connected to the second flushing valve.

[0015] Furthermore, the spray plate is welded to the protective cover shell to form a sealed spray chamber, and the first flushing valve, the second flushing valve and the diverter plate are also connected to the protective cover shell by welding.

[0016] Furthermore, it also includes a protective net, which is arranged on the outer surface of the protective cover module. The beneficial effects of the present application are:

[0017] The self-cleaning condensing compressor unit of the present invention can use the high-pressure water for cleaning in the spray unit to thoroughly clean the condenser module from the inside to the outside, avoiding a series of problems during conventional cleaning, such as time-consuming and labor-intensive cleaning with a soft brush and incomplete cleaning, hard steel brush cleaning that damages the condenser copper tube, and high-pressure water flushing requiring high water pressure. At the same time, it overcomes the problem that the inside of the condenser cannot be thoroughly cleaned during brushing and flushing. The entire cleaning process does not require the condenser to be removed, and cleaning can be achieved by simply connecting the quick connector, which is fast and efficient. At the same time, the three-way connector 81, flushing valves 71, 74 and diverter plate 73 can adjust the flow rate of high-pressure water for cleaning according to actual conditions, so that the water flow rate matches the cleaning process and avoids waste of water resources. The self-cleaning device of the present invention can also be used on other marine environmental control equipment such as marine heat exchangers and marine fans, and has a good cleaning effect on salt stains and other dirty blockages on the surface of the equipment. It is also suitable for environmental control equipment such as aircraft, automobiles, and mining equipment that are used in environments with a lot of sand and dust.

Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work belong to the scope of protection of the present invention. The following is a detailed description in combination with the embodiments of the present invention.

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively and meticulously below in conjunction with the accompanying drawings of the specification, but the protection scope of the present invention is not limited to the following specific embodiments.

[0024] like Figure 3 As shown, the refrigerant enters the condenser module 2 through the pipeline module 5 and the compressor module 6 to be cooled. The cooling air dissipates the heat of the condenser module 2 under the forced convection of the condensing fan module 1 and is discharged from the product. The heat drive module 4 controls the start and stop of the condensing fan module 1 and the compressor module 6 and the speed of operation to realize the thermal management function of the self-cleaning condensing compressor unit. The high-pressure water for cleaning flows into the flushing hose 82 in two streams through the three-way joint 81 of the flushing module 8, and then enters the water collecting plate 77 from the flushing valves 71 and 74 of the protective cover module 7 through the quick joints 83 and 84, and finally sprays from the spray hole of the spray plate 72 in a fan-shaped surface to the inner side of the condenser module 2, cleaning the condenser module 2 from the inside to the outside. The three-way joint 81, the flushing valves 71, 74 and the diverter plate 73 can adjust the flow rate of the high-pressure water for cleaning according to the actual situation, thereby realizing the self-cleaning function of the self-cleaning condensing compressor unit.

[0025] The condensing fan module 1, the condenser module 2, the heat drive module 4, the pipeline module 5, the compressor module 6, the protective cover module 7 and the flushing module 8 are fixed on the frame module 3. The bottom of the condensing fan module 1, the heat drive module 4 and the compressor module 6 are treated with shock-absorbing pads and damping strips; the mounting surfaces of the condenser module 2 and the protective cover module 7 are sealed with insulation boards to ensure that the cooling air passes through the windward surface of the condenser module 2 as much as possible.

[0026] The upper part of the protective cover module 7 is an integrated structure, the spray plate 72 is welded to the protective cover shell 76 to form a sealed spray chamber, and the flushing valves 71, 74 and the diverter plate 73 are also connected to the protective cover shell 76 by welding.

[0027] The protective net 75 on the protective cover module 7 is connected to the protective cover shell 76 by riveting or spot welding technology, and the edge of the protective net is fixed by a pressure strip to prevent the edge of the protective net from being dislodged under the action of uncontrollable force.

[0028] The flushing hose 82 in the flushing module 8 is connected to the three-way joint 81 and the flushing valves 71 and 74 by expansion connection to ensure good sealing at the joints.

[0029] Example

[0030] The self-cleaning condensing compressor unit includes a condensing fan module 1, a condenser module 2, a frame module 3, a heat drive module 4, a pipeline module 5, a compressor module 6, a protective cover module 7 and a flushing module 8. The condenser module 2 is used to cool the refrigerant medium discharged by the pipeline module 5 and the compressor module 6; the condensing fan module 1 discharges the heat generated by the cooling process of the condenser module 2 out of the product through the forced convection function; the condensing fan module 1, the condenser module 2, the heat drive module 4, the pipeline module 5, the compressor module 6, the protective cover module 7 and the flushing module 8 are all fixed on the frame module 3; the heat drive module 4 is used to control the start and stop and the speed of operation of the condensing fan module 1 and the compressor module 6, and monitor the product operation status parameters in real time, so as to realize the thermal management function of the product; the compressor module 6 is used to force the refrigerant medium to flow; the protective cover module 7 and the flushing module 8 are used to self-clean the condenser module 2.

[0031] The protective cover module 7 includes a first flushing valve 71, a spray plate 72, a diverter plate 73, a second flushing valve 74, a protective net 75, a protective cover shell 76, and a water collecting plate 77. A water collecting plate 77 is welded to the upper end of the protective cover shell 76. The area where the water collecting plate 77 is welded to the upper end of the protective cover shell 76 forms a water collecting trough. The first flushing valve 71 and the second flushing valve 74 are respectively arranged on both sides of the water collecting trough. The spray plate 72 is welded to the lower end of the water collecting plate 77 and the inner side of the protective cover shell 76. The spray plate 72 is an arc-shaped structure, and there are a plurality of spray holes on the spray plate 72. The spray range of the spray holes should be able to cover all areas inside the condenser module 2, so as to achieve thorough cleaning of the condenser module 2 from the inside to the outside.

[0032] Furthermore, the first flushing valve 71 and the second flushing valve 74 are interconnected. (When the water pressure at one end is insufficient, the other end can automatically compensate for the water pressure to achieve uniformity of the water spraying amount, which is more conducive to cleaning various positions of the condenser module 2).

[0033] Furthermore, a diverter plate 73 is included, and the diverter plate 73 is arranged between the first flush valve 71 and the second flush valve 74. (It buffers the water pressure to ensure the uniformity of the water pressure at various positions in the water collection tank, and prevents the excessive water pressure from impacting the valve core on the opposite side and causing damage to the valve core).

[0034] Furthermore, the spray holes arranged on the spray plate 72 are divided into a spray area A and a spray area B at a 45° angle by the protective cover shell 76 and the water collecting plate 77 .

[0035] Furthermore, the spraying area of ​​the spraying zone A should be larger than the area of ​​the spraying zone B.

[0036] Furthermore, the number of spray holes in the spray area A should be less than the number of spray holes in the spray area B. (The clean water flow discharged by the water collecting plate 77 forms a certain pressure in the spray area A, and the water flow is more likely to be sprayed out from the spray area B, thereby ensuring uniform cleaning of each position of the condenser module 2.)

[0037] Furthermore, the flushing module 8 includes a three-way connector 81, a flushing hose 82, a first quick connector 83, and a second quick connector 84. One end of the three-way connector 81 is connected to a high-pressure water source, and the other two ends are respectively connected to the flushing hoses 82. One flushing hose 82 is connected to the first quick connector 83, and the other flushing hose 82 is connected to the second quick connector 84. The first quick connector 83 is connected to the first flushing valve 71, and the second quick connector 84 is connected to the second flushing valve 74.

[0038] Furthermore, the spray plate 72 is welded to the protective cover shell 76 to form a sealed spray chamber, and the first flushing valve 71, the second flushing valve 74 and the diverter plate 73 are also connected to the protective cover shell 76 by welding.

[0039] Furthermore, it also includes a protection net 75, which is arranged on the outer surface of the protection cover module 7.

[0040] The protective net 75 is connected to the protective cover shell 76 by riveting or spot welding technology, and the edge of the protective net is fixed by a pressure strip to prevent the edge of the protective net from being dislodged under the action of uncontrollable force.

[0041] In a possible embodiment, the air inlet of the condensing fan module faces the condenser module; and the condensing fan module is electrically connected to the heat drive module.

[0042] In a possible embodiment, the condenser module uses two completely identical core assemblies connected in series and placed on both sides of the condensing fan module respectively to form a compound eye structure, which is beneficial to reducing wind resistance and improving the heat exchange efficiency of the core assembly.

[0043] In a possible embodiment, the protective cover module is located outside the air inlet of the condenser module to protect the fins and heat exchange tubes of the condenser module from being damaged by bumps; the protective cover module includes a protective net 75 to prevent lint and other debris in the air from being sucked into the condenser module.

[0044] In a possible embodiment, a spray unit is integrated on the upper part of the protective cover module. The specific implementation process is: high-pressure water for cleaning enters the spray unit through flushing valves 71 and 74, flows to the spray plate 72 after being buffered in the water collecting plate 77, and the spray hole of the spray plate 72 adopts a fan-shaped design. The water outlet of the spray hole can cover the inner side of the condenser module, ensuring that the cleaning water cleans the condenser module from the inside to the outside, and the cleaning is more thorough.

[0045] In a possible embodiment, the spray unit includes a diverter plate 73 to ensure uniformity of water spray and prevent the flushing valves 71 and 74 from being impacted by excessive water pressure.

[0046] In a possible embodiment, the flushing valves 71 and 74 can adjust the flow rate of high-pressure cleaning water and have a one-way check function to prevent the high-pressure cleaning water from overflowing from the flushing valve when the flow rate is too fast.

[0047] In a possible embodiment, high-pressure cleaning water flows from the three-way joint 81 of the flushing module into the flushing hose 82 and then flows into the flushing valves 71 and 74 on the protective cover module through quick connectors 83 and 84 respectively.

[0048] In a possible embodiment, the flushing module can be connected to the flushing valves 71 and 74 of the protective cover module to clean the two condenser modules in the product in turn; the flushing module can also be connected to the flushing valves 71 (or flushing valves 74) of the two condenser modules in the product respectively to clean the two condenser modules at the same time.
