Description

Technical Field

[0001] The utility model relates to the field of modular machines, in particular to an ice melting structure and a modular machine. Background Art

[0002] The temperature in northern my country is generally below zero in winter, and the cold weather will cause the condensed water from the heat exchanger to freeze quickly when the module unit is running, thus affecting the normal operation of the module unit. In order to solve the problem of the condensed water from the heat exchanger freezing quickly, an electric heating belt is usually installed under the heat exchanger (for example, the anti-icing structure disclosed in the Chinese patent document with application number CN201910688283.6). However, the power of the electric heating belt is constant and cannot be adjusted according to the ambient temperature, which will lead to increased energy consumption. At the same time, when installing the heating belt, if you are not careful in operation, it is easy to damage the insulation layer of the cable, which will cause fire when the module unit is running, posing certain safety hazards.

[0003] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

DETAILED DESCRIPTION

[0034] The utility model provides an ice melting structure and a module machine. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0035] In the description of the present utility model, it should be understood that the terms "upper", "lower", "left", "right", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, and a specific direction structure and operation, and therefore, cannot be understood as a limitation on the present utility model. In addition, "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means more than two.

[0036] See also Figure 1 The utility model provides an ice-melting structure, including an air compressor 1, a first plate heat exchanger 2, an ice-melting pipeline 3 and a circulation pump 5. Among them, the air compressor 1 is a component of the modular machine; the first plate heat exchanger 2 is additionally added, and the first plate heat exchanger 2 is provided with a refrigerant inlet end connected to the output end of the air compressor 1, so that when the air compressor 1 compresses the refrigerant to a high temperature and high pressure state, the refrigerant in the high temperature and high pressure state can first enter the first plate heat exchanger 2; the ice melting pipe 3 is arranged below the fin heat exchanger 4 of the modular machine, and antifreeze is injected into the ice melting pipe 3; the circulating pump 5 is used to transport the antifreeze in the ice melting pipe 3 to the first plate heat exchanger 2, and since the refrigerant can first enter the first plate heat exchanger 2 after being compressed by the air compressor 1, the antifreeze can be heated when the antifreeze is transported to the first plate heat exchanger 2, and when the antifreeze is heated and then transported back to the ice melting pipe 3, the ice melting pipe 3 can be heated, thereby melting the ice layer below the fin heat exchanger 4.

[0037] It can be seen that the utility model adds an additional first plate heat exchanger 2 to the module machine and adds an ice-melting pipe 3 under the fin heat exchanger 4, so that the heat of the high-temperature and high-pressure refrigerant compressed by the compressor can be partially used to heat the antifreeze in the ice-melting pipe 3, thereby achieving the purpose of melting ice. Compared with the method of installing an electric heating belt under the fin heat exchanger 4 to melt ice, the utility model does not need to use an electric heating belt to melt ice, so there will be no safety hazard of ignition of the cable insulation layer. In addition, since the speed of the circulating pump 5 can be adjusted, the speed of the circulating pump 5 can be adjusted according to the actual ice-melting situation, and then the flow of antifreeze entering the first plate heat exchanger 2 can be adjusted, so that the heat carried by the refrigerant in a high-temperature and high-pressure state can be reasonably distributed and used, which can not only reduce energy consumption, but also avoid waste of heat energy.

[0038] Specifically, the antifreeze liquid can be water, ethylene glycol, etc.

[0039] Furthermore, the ice-melting pipe 3 is an ice-melting coil. When the ice-melting pipe 3 is in the form of a coil, it can extend the conveying path of the antifreeze liquid in the ice-melting pipe 3, so that the heat carried by the antifreeze liquid can be used more for melting ice, and the ice-melting effect is better.

[0040] Furthermore, the ice-melting structure also includes a circulating liquid infusion pipe 6, two of which are provided, and the two ends of one of the circulating liquid infusion pipes 6 are respectively connected to the liquid inlet end of the first plate heat exchanger 2 and the liquid outlet end of the ice-melting pipe 3, and the two ends of the other circulating liquid infusion pipe 6 are respectively connected to the liquid outlet end of the first plate heat exchanger 2 and the liquid inlet end of the ice-melting pipe 3; the circulating pump 5 is arranged on one of the circulating liquid infusion pipes 6; the outer wall of the circulating liquid infusion pipe 6 is also coated with an insulation layer to reduce the heat loss of the antifreeze when it is transported between the first plate heat exchanger 2 and the ice-melting pipe 3, thereby reducing the waste of heat energy.

[0041] Furthermore, the ice melting structure further includes a controller. The controller is electrically connected to the circulation pump 5, so that the user can control the speed of the circulation pump 5 based on the actual ice melting effect or the ambient temperature. In order to facilitate the control of the speed of the circulation pump 5, the controller can be electrically connected to the operation panel, and the operation panel can be set on the cabinet of the modular machine unit.

[0042] Furthermore, the ice-melting structure also includes a temperature sensor. The temperature sensor is electrically connected to the controller, and the temperature sensor is used to monitor the ambient temperature. The ambient temperature can be the ambient temperature outside the module machine, or the ambient temperature around the ice-melting pipe 3. The utility model monitors the ambient temperature by setting a temperature sensor, and electrically connects the temperature sensor to the controller, so that the rotation speed of the circulation pump 5 can be adjusted based on the monitored ambient temperature, so that the rotation speed of the circulation pump 5 can be adjusted according to the actual ice-melting demand. For example, when the ambient temperature is high, the condensed water is not easy to freeze, so the rotation speed of the circulation pump 5 can be adjusted to reduce the rotation speed of the circulation pump 5, thereby reducing energy consumption.

[0043] like Figure 2 As shown, further, the ice melting structure also includes a water receiving tray 7; the water receiving tray 7 is arranged below the fin heat exchanger 4 of the module machine, and a drain nozzle 8 is provided at the bottom of the water receiving tray 7; the ice melting pipe 3 can be directly installed in the water receiving tray 7, so that when the ice layer melts through the ice melting pipe 3, the melted water can be discharged to the outside of the module machine with the help of the water receiving tray 7 and the drain nozzle 8.

[0044] The utility model also provides a modular machine, comprising the aforementioned ice melting structure; and further comprising a fin heat exchanger 4 , a four-way valve 9 , a second plate heat exchanger 10 and an expansion valve 11 .

[0045] Among them, the fin heat exchanger 4 is located above the ice melting pipe 3; the two pipe openings of the four-way valve 9 are respectively connected to the outlet end of the fin heat exchanger 4 and the inlet end of the air compressor 1, and one of the other two pipe openings is connected to the refrigerant outlet end of the first plate heat exchanger 2; the refrigerant inlet end of the second plate heat exchanger 10 is connected to the remaining pipe opening of the four-way valve 9; the expansion valve 11 is respectively connected to the refrigerant outlet end of the second plate heat exchanger 10 and the inlet end of the fin heat exchanger 4.

[0046] The fin heat exchanger 4, the four-way valve 9, the second plate heat exchanger 10 and the expansion valve 11 are components of the existing modular machine, but due to the setting of the ice melting structure, the modular machine provided by the utility model has less safety hazards and lower energy consumption during operation. Two circulating water pipes 12 are provided, and the two circulating water pipes 12 are respectively connected to the water inlet and the water outlet of the second plate heat exchanger 10.

[0047] Furthermore, the modular machine also includes a circulating water pipe 12 and a circulating water pump 13. Two circulating water pipes 12 are provided, and the two circulating water pipes 12 are respectively connected to the water inlet and the water outlet of the second plate heat exchanger 10; the circulating water pump 13 is provided on one of the circulating water pipes 12, and the circulating water pump 13 can transport the water stored in the water storage device (such as a water tank) to the second plate heat exchanger 10, and then exchange heat with the refrigerant compressed by the compressor, thereby heating up, and the heated water can be transported to different scenarios for use. Of course, the modular machine provided by the utility model is not limited to heating low-temperature water.

[0048] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and utility model concept of the utility model, and all these changes or substitutions should fall within the protection scope of the claims attached to the utility model.
