Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, specifically to a high-efficiency and energy-saving evaporator device for refrigeration and air conditioning equipment. Background Technology

[0002] The evaporator is a core component of refrigeration and air conditioning equipment, responsible for the crucial heat exchange process that enables refrigeration. Its working principle is as follows: low-temperature, low-pressure liquid refrigerant absorbs heat from the surrounding air or coolant within the evaporator and evaporates into a gas. This process absorbs a large amount of heat, thereby lowering the temperature of the cooled medium. Evaporators typically consist of copper tubes and aluminum fins. The aluminum fins are tightly bonded to the copper tubes through an expansion process, increasing the heat exchange area and improving heat exchange efficiency. Evaporators can be classified according to the cooling medium into air-cooling and liquid-cooling types, and their structural forms include tube-fin, tube-strip, and stacked types, widely used in household air conditioners, automotive air conditioners, and industrial refrigeration systems.

[0003] During operation, existing evaporators may react with the chemicals in the refrigerant to produce impurities. These impurities can hinder refrigerant flow, increase flow friction, and form scale on the inner wall of the evaporator pipes. This scale can deposit inside the evaporator pipes, forming an insulation layer that hinders heat exchange between the refrigerant and the pipe wall, resulting in insufficient cooling capacity of the system. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-efficiency and energy-saving evaporator device for refrigeration and air conditioning equipment, which can filter the refrigerant inside the copper tubes of the evaporator.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency energy-saving evaporator device for refrigeration and air conditioning equipment, comprising an evaporator body, multiple sets of copper pipe circuits extending from both sides of the evaporator body, a placement plate on one bottom side of the evaporator body, a filter assembly on the placement plate, a water circuit regulating assembly connected to the top surface of the filter assembly, and the water circuit regulating assembly connected to two sets of copper pipe circuits through water pipes.

[0006] Furthermore, the filter assembly includes a filter body, with an inlet and an outlet respectively provided on both sides of the top surface of the filter body. The inlet and outlet are connected to the water circuit regulating assembly through a filter pipe and a return pipe, respectively.

[0007] Furthermore, the water circuit regulating component includes an inlet pump connected to the outflow circuit of the copper pipe circuit and an outlet pump connected to the return circuit of the copper pipe circuit. An impurity detection sensor is installed at the inlet end of the inlet pump, and a switching valve is connected to the end of the inlet pump. A filter pipe is connected to the lower end of the switching valve. The inside of the switching valve is connected to a three-way pipe through a connecting pipe. The opening at the lower end of the three-way pipe is connected to the return pipe, and the last opening of the three-way pipe is connected to the outlet pump. A one-way valve plate with an upward opening is installed on the inner wall of the lower end of the three-way pipe.

[0008] Furthermore, the filter tube and return tube are provided with flange rings at the connection end with the filter body, and the flange rings are fixed to the filter body by bolts.

[0009] Furthermore, a sealing ring is provided on the top surface of the filter body, which wraps around the outside of the flange ring.

[0010] Furthermore, the placement plate is provided with a limiting semi-ring that fits against the outer side of the filter body, and a rotating block that fits against the outer side of the filter body after rotation is provided at the opening of the limiting semi-ring.

[0011] Furthermore, a refrigerant replenishment port is provided in the middle of the top surface of the filter body.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By setting up a filter assembly, impurities in the water can be effectively removed, preventing blockage of the copper pipe circuit and extending the service life of the equipment. By setting up a water circuit regulating assembly, on the one hand, precise control of the water flow in the evaporator can be achieved, reducing ineffective circulation and improving heat exchange efficiency. On the other hand, with the cooperation of the switching valve and impurity detection sensor, water quality can be monitored in real time and the water circuit can be automatically switched, allowing water with low impurity content to pass through and sending water with high impurity content into the filter assembly, thus preventing impurities from entering the core components of the evaporator.

[0014] 2. By using flange connections for fixation, the filter assembly can be disassembled while ensuring no leakage at the connection point, facilitating maintenance and repair by staff. The sealing ring not only further ensures the sealing of the connection but also guides the insertion of the flange ring, allowing for quick alignment between the flange ring and the screw holes on the filter body, improving work efficiency. The use of a limiting half-ring and rotating block ensures stable installation of the filter body, reducing vibration and noise. A refrigerant replenishment port located in the center of the top surface of the filter body allows staff to replenish refrigerant to maintain efficient system operation, saving operational steps and improving work efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1 to 4 As shown, a high-efficiency energy-saving evaporator device for refrigeration and air conditioning equipment includes an evaporator body 1. Multiple sets of copper pipe circuits 101 are extended on both sides of the evaporator body 1. A placement plate 102 is provided on the bottom surface of one side of the evaporator body 1. A filter assembly 2 is provided on the placement plate 102. A water circuit regulating assembly 3 is connected to the top surface of the filter assembly 2. The water circuit regulating assembly 3 is connected to the copper pipe circuits 101 through water pipes.

[0022] like Figure 1 As shown, the main improvement of this utility model lies in its ability to filter the refrigerant inside the evaporator copper tubes, such as... Figures 1 to 4As shown, in this utility model, a high-efficiency energy-saving evaporator device for refrigeration and air conditioning equipment operates as follows: When water in the copper pipe circuit 101 flows to the inlet pump 301, it enters the switching valve 304 under the push of the inlet pump 301. At this time, the water has passed the impurity detection sensor 303, which detects the impurity content in the water. When the impurity content is low, the switching valve 304 adjusts the outlet opening to the connecting pipe 305, allowing the water to flow through the three-way pipe 306 to the outlet pump 302, and then back into the copper pipe circuit 101. At this time, the one-way valve plate 307 in the three-way pipe 306 is closed under pressure, which can prevent the water from flowing into the return pipe 205, avoid backflow, and ensure the safe operation of the system. When the impurity content is high, the switching valve 304 adjusts the water outlet to the filter pipe 204, and the water flows into the filter body 201 for filtration. After filtration, the water flows through the return pipe 205 into the three-way pipe 306. At this time, the one-way valve plate 307 in the three-way pipe 306 is opened by impact, and the filtered water flows back into the copper pipe circuit 101 under the push of the water pump 302, completing the filtration of the water flow.

[0023] like Figure 1 and Figure 2 As shown, the filter assembly 2 includes a filter body 201. The top surface of the filter body 201 is provided with an inlet 202 and an outlet 203 on both sides. The inlet 202 and the outlet 203 are connected to the water circuit regulating assembly 3 through a filter pipe 204 and a return pipe 205, respectively.

[0024] Specifically, water containing impurities will enter the filter body 201 through the filter pipe 204 and the inlet 202. The water will then be filtered to prevent impurities from accumulating in the copper pipe circuit 101 and extend the service life of the equipment. After filtration, the water will enter the water circuit regulating component 3 through the outlet 203 and the return pipe 205, and then flow back into the copper pipe circuit 101 to achieve the filtration of impurities in the water.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, the water circuit regulating component 3 includes an inlet pump 301 connected to the outflow circuit of the copper pipe circuit 101 and an outlet pump 302 connected to the return circuit of the copper pipe circuit 101. An impurity detection sensor 303 is provided at the inlet end of the inlet pump 301. A switching valve 304 is connected to the end of the inlet pump 301. A filter pipe 204 is connected to the lower end of the switching valve 304. The inner side of the switching valve 304 is connected to a three-way pipe 306 through a connecting pipe 305. The opening at the lower end of the three-way pipe 306 is connected to the return pipe 205. The last opening of the three-way pipe 306 is connected to the outlet pump 302. A one-way valve plate 307 with an upward opening is provided on the inner wall at the lower end of the three-way pipe 306.

[0026] Specifically, when the water in the copper pipe circuit 101 flows to the inlet pump 301, it passes through the impurity detection sensor 303. The impurity detection sensor 303 detects the impurity content in the water. When the impurity content is low, the switching valve 304 will allow the water to flow to the outlet pump 302 through the connecting pipe 305, and then return to the copper pipe circuit 101. When the impurity content is high, the water will flow through the filter pipe 204 under the guidance of the switching valve 304 into the filter body 201 for filtration. After filtration, the water will enter the three-way pipe 306 through the return pipe 205, and return to the copper pipe circuit 101 under the push of the outlet pump 302, thus completing the filtration of the water.

[0027] like Figure 2 and Figure 3 As shown, the filter pipe 204 and the return pipe 205 are connected to the filter body 201 with a flange ring 206 at the connection end. The flange ring 206 is fixed to the filter body 201 by bolts.

[0028] like Figure 2 As shown, a sealing ring 207 is provided on the top surface of the filter body 201, which wraps around the outside of the flange ring 206.

[0029] Specifically, the filter tube 204, return pipe 205, and filter body 201 are fixedly connected by a flange ring 206. This ensures that there is no leakage at the connection and allows the filter body 201 to be removed by disassembling the flange ring 206, making it convenient for staff to maintain and repair the filter body 201. The sealing ring 207 wrapped around the outside of the flange ring 206 can be used in conjunction with the flange ring 206 to further ensure the sealing of the connection. It can also guide the insertion of the flange ring 206, so that the flange ring 206 can be quickly aligned with the screw holes on the filter body 201, improving installation efficiency.

[0030] like Figure 2 As shown, a limiting semi-ring 103 that fits the outer side of the filter body 201 is provided on the placement plate 102, and a rotating block 104 that fits the outer side of the filter body 201 after rotation is provided at the opening of the limiting semi-ring 103.

[0031] Specifically, by setting the limiting semi-ring 103, the filter body 201 can be quickly positioned and placed in the designated position during installation and disassembly, while the rotating block 104 can fix the filter body 201 after installation, thereby improving structural stability and reducing vibration and noise.

[0032] like Figure 2 As shown, a refrigerant replenishment port 208 is provided in the middle of the top surface of the filter body 201.

[0033] Specifically, by setting a refrigerant replenishment port 208 in the middle of the top surface of the filter body 201, the operator can replenish refrigerant from here to maintain the efficient operation of the system, saving operation steps and improving work efficiency.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
