Description

Technical field:

[0001] The utility model relates to the technical field of heat exchange, in particular to a novel heat exchange device. Background technology:

[0002] A heat pump is a device that transfers heat energy from a low-temperature heat source to a high-temperature heat source. It is mainly composed of a compressor, an evaporator, an expansion valve, and a condenser. The working principle of a heat pump is a mechanical device that forces heat to flow from a low-temperature object to a high-temperature object in a reverse cycle. It consumes only a small amount of reverse cycle net work to obtain a large amount of heat supply, and can effectively utilize low-grade heat energy that is difficult to apply to achieve energy conservation. In order to utilize the heat energy generated by the heat pump, the heat pump is used in conjunction with a heat exchanger. The outdoor heat energy potential is unlimited. The heat pump uses low-density energy (water and gas) as a heat source to exchange heat with the heat-absorbing medium in the heat exchanger. It is more energy-saving, fast, and safer than simply using an electric heater for heating.

[0003] Traditional heat exchangers mostly use welding to make the heat exchange coil and the shell into an integral structure. The overall structure has good sealing performance, but is not easy to disassemble. When individual coils are damaged or scale adheres to the surface of the heat exchange coil and affects heat exchange, the entire structure can only be replaced, resulting in serious waste of equipment materials. Utility model content:

[0004] The purpose of the utility model is to provide a new type of heat exchange equipment.

[0005] The purpose of the utility model is implemented by the following technical scheme: a new type of heat exchange equipment, which includes a heat pump, a condenser, a flange and a shell with an opening at the top; the flange is detachably connected to the top opening of the shell, and a drainage pipeline is welded at the opening of the flange; the condenser is placed in the shell, the inlet end of the condenser passes through the disk surface of the flange and is connected to the medium outlet of the heat source output end of the heat pump through the medium output pipeline, and the outlet end of the condenser passes through the disk surface of the flange and is connected to the medium inlet of the heat source output end of the heat pump through the medium reflux pipeline; the outer side wall of the bottom of the shell is connected with a liquid inlet pipeline, the bottom surface of the shell is set to an arc-shaped convex surface, and the bottom surface outside the shell is connected with a sewage pipeline.

[0006] Preferably, a first temperature sensor, a flow meter and a liquid inlet regulating valve are provided on the liquid inlet pipeline.

[0007] Preferably, a second temperature sensor and a drain valve are provided on the drain line.

[0008] Preferably, the second temperature sensor is electrically connected to an input end of a controller, and an output end of the controller is electrically connected to the liquid inlet regulating valve.

[0009] Preferably, a pressure gauge is provided on the side wall of the shell.

[0010] Preferably, a sewage valve is provided on the sewage pipeline.

[0011] Preferably, the condenser is a spiral structure.

[0012] The advantages of the utility model are as follows: First, the utility model inputs the heating medium at the heat source output end into the condenser through the heat pump, and at the same time, sends the liquid material into the shell. After the heating medium exchanges heat with the liquid material, the medium returns to the heat source output end of the heat pump to absorb heat again and participate in the cycle; after the liquid material absorbs heat, it is discharged from the shell for users to use. After the heat exchange equipment is used for a long time, when scale adheres to the outer surface of the condenser or the inner surface of the shell, the flange is removed from the shell, the condenser is taken out, and after cleaning the condenser and the inside of the shell accordingly, the drain valve is opened, and scale and other impurities are discharged from the drain pipeline.

[0013] Second, a liquid inlet regulating valve is provided on the liquid inlet pipeline, and a second temperature sensor is provided on the liquid discharge pipeline. The second temperature sensor is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the liquid inlet regulating valve. The temperature of the liquid material after heat exchange in the liquid discharge pipeline is monitored by the second temperature sensor. When the temperature is lower than the set range, the controller controls the opening of the liquid inlet regulating valve to become smaller, the flow rate of the liquid material to be heat exchanged becomes smaller, the flow rate becomes slower, the heat exchange time is extended, and the temperature of the material after heat exchange reaches the set range.

[0018] like Figure 1 As shown, a novel heat exchange device comprises a heat pump 1, a condenser 2, a flange 3 and a shell 4 with an opening at the top. The heat pump 1 is an existing device, and the specific structure is not repeated here. The heat pump 1 uses air and low-temperature water as heat sources, the condenser 2 is used as a heat exchange pipe, and the shell 4 contains materials to be heat exchanged; the top opening of the shell 4 is connected with a flange 3 by bolts, which is convenient for disassembly of the flange 3 and is conducive to later replacement and cleaning. A drainage pipeline 5 is welded at the opening of the flange 3;

[0019] The condenser 2 is placed in the shell 4. The condenser 2 is a spiral structure. Due to its unique spiral design, the heat exchange equipment can provide a larger heat transfer area in a limited space, thereby improving the heat transfer efficiency. The inlet end of the condenser 2 passes through the disk surface of the flange 3 and is connected to the medium outlet of the heat source output end of the heat pump 1 through the medium output pipeline 6. The outlet end of the condenser 2 passes through the disk surface of the flange 3 and is connected to the medium inlet of the heat source output end of the heat pump 1 through the medium return pipeline 7.

The second temperature sensor 14 is electrically connected to the input end of the controller 16, and the output end of the controller 16 is electrically connected to the inlet regulating valve 13. The temperature of the liquid material after heat exchange in the discharge pipeline 5 is monitored by the second temperature sensor 14. When the temperature is lower than the set range, the controller 16 controls the opening of the inlet regulating valve 13 to become smaller, the flow rate of the liquid material to be heat exchanged becomes smaller, the flow rate becomes slower, and the heat exchange time is extended, so that the temperature of the material after heat exchange reaches the set range;

[0021] The bottom surface of the shell 4 is set as an arc-shaped convex surface, which is conducive to the discharge of scale impurities, and the bottom surface of the shell 4 is connected to a sewage pipeline 17. When the heat exchange equipment needs to be cleaned, the flange 3 is removed, the condenser 2 is taken out, and the inside of the shell 4 is cleaned. Impurities such as scale are discharged from the sewage pipeline 17, and a sewage valve 18 is provided on the sewage pipeline 17.

After heat exchange, the temperature of the medium drops to -15-80℃, and the medium returns to the heat source output end of the heat pump 1 through the medium return pipeline 7 to absorb heat again and participate in the circulation; after the liquid material in the shell 4 exchanges heat with the heating medium in the condenser 2, the liquid material absorbs heat and rises in temperature from the drain pipeline 5. Discharge, when the second temperature sensor 14 detects that the temperature of the liquid material after heat exchange in the discharge pipeline 5 is lower than the set range, the controller 16 controls the opening of the liquid inlet regulating valve 13 to become smaller, the flow rate of the liquid material to be heat exchanged becomes smaller, the flow rate becomes slower, the heat exchange time is extended, and the temperature of the liquid material after heat exchange reaches the set range; after the heat exchange equipment has been used for a long time, when scale adheres to the outer surface of the condenser 2 or the inner surface of the shell 4, the flange 3 is removed from the shell 4, the condenser 2 is taken out, and after cleaning the condenser 2 and the inside of the shell 4 accordingly, the drain valve 18 is opened, and impurities such as scale are discharged from the drain pipeline 17.
