Description

Technical Field

[0001] The invention relates to the field of heat pipes for air conditioning systems, and in particular to a heat pipe device with high efficiency heat exchange. Background Art

[0002] Heat pipe is a superconducting heat exchange component. The interior of the heat pipe is filled with high-efficiency heat flow materials such as refrigerant. When one end of the heat pipe (evaporation section) is heated, the working medium in the pipe vaporizes due to the heat. The heat-absorbing gaseous working medium flows along the pipe to the other end (condensation section), where it releases heat to the heated medium. The gaseous working medium condenses into liquid due to heat loss, and flows back to the evaporation section under the action of capillaries and gravity, thus completing a cycle. Its thermal conductivity exceeds that of any known metal.

[0003] There are two types of heat pipes currently used in air conditioning systems:

[0004] Form 1: Single channel heat pipe - U-shaped pipe (for air conditioning units), see Figure 7 ;

[0005] Form 2: Dual-channel heat pipe (mainly used for civil air conditioning fresh air units), see Figure 8 ;

[0006] The treatment method of the single-channel heat pipe constant temperature and humidity unit is as follows: With a single-channel heat pipe constant temperature and humidity system: 26℃ air is pre-cooled to 18℃ through the heat pipe (1), treated to an outlet air temperature of 12℃ (7-9℃ for the high-tech plant MAU unit) / 95% through the cold water coil, treated to 20℃ through the heat pipe (2) preheating section, and sent to the room. Chilled water only needs to deal with an air temperature difference of 6℃, and the reheating section saves electric heat (or steam). For details, see Fig. 9 .

[0007] The drawback of this treatment method is that when the inlet air temperature is lower than the surface cooling section (cold water coil) (such as 0°C in winter), the heat pipe (1) (2) will not be able to perform heat exchange, and may even release heat from the rear end of the surface cooling section (at this time, the temperature at the rear end of the surface cooling section is greater than the inlet air temperature) to the inlet end, which in turn increases the energy consumption of the rear end heating section (steam heating section).

[0008] Therefore, it is urgent to invent a heat pipe device that can perform heat exchange in both winter and summer and can effectively save the energy consumption of precooling or preheating in the front section and re-preheating in the back section of the air-conditioning unit. Summary of the invention

[0009] To this end, the present invention provides a heat pipe device for high-efficiency heat exchange, which is connected to a PLC controller by setting up at least three groups of heat pipes through solenoid valves, pump groups, and temperature sensors for controlling flow directions; wherein the PLC controller is connected to at least one group of temperature sensors for receiving ambient temperature, and after processing and analyzing the received ambient temperature, controls the switches of the solenoid valves for each flow direction, turns on the valve groups, pump groups, and heat pipes for heat exchange, thereby achieving the effect of heat exchange, so as to solve the problems existing in the prior art.

[0039] The first heat pipe group 1 is connected to the fresh air or mixed air inlet, and the third heat pipe group 3 is connected to the indoor return air area;

[0040] The pipe openings of the No. 1 heat pipe group 1, the No. 2 heat pipe group 2 and the No. 3 heat pipe group 3 are all provided with temperature sensors 10, and the temperature sensors 10, the pump group, the No. 1 solenoid valve and the No. 2 solenoid valve are all connected to the PLC controller 11;

[0041] The first connecting pipe group 12 and the second connecting pipe group 13 can be a single pipe with a larger diameter or multiple pipes arranged side by side.

[0042] Furthermore, the No. 1 heat pipe group 1 and the No. 2 heat pipe group 2 are arranged side by side in parallel, the No. 3 heat pipe group 3 is placed in the indoor return air area, and the No. 1 connecting pipe group 12 and the No. 2 connecting pipe group 13 are arranged vertically to the No. 1 heat pipe group 1 and the No. 2 heat pipe group 2.

[0043] Furthermore, the No. 2 heat pipe group 2 includes two No. 2 heat pipes 201 and multiple No. 2 shunt pipes 202. The two No. 2 heat pipes 201 are arranged side by side up and down, and multiple No. 2 shunt pipes 202 are connected between the two No. 2 heat pipes 201. The multiple No. 2 shunt pipes 202 are evenly distributed in multiple rows.

[0044] Furthermore, each of the No. 3 heat pipe groups 3 includes two No. 3 heat pipes 301 and multiple No. 3 shunt pipes 302, the two No. 3 heat pipes 301 are distributed side by side up and down, and multiple No. 3 shunt pipes 302 are connected between the two No. 3 heat pipes 301, and the multiple No. 3 shunt pipes 302 are evenly distributed in multiple rows.

[0045] Furthermore, the No. 1 connecting pipe group 12 includes two No. 1 connecting pipes, which are arranged side by side up and down, and one end of the two No. 1 connecting pipes is connected to the two No. 1 heat pipes 101, and the other end of the two No. 1 connecting pipes is connected to the two No. 2 heat pipes 201. A No. 1 solenoid valve A4 is provided on the upper No. 1 connecting pipe, a No. 1 solenoid valve B5 is provided on the lower No. 1 connecting pipe, and a No. 2 pump group 9 is provided on the lower No. 1 connecting pipe.

[0046] Furthermore, the No. 2 connecting pipe group 13 includes two No. 2 connecting pipes, which are distributed side by side up and down, and one end of the two No. 2 connecting pipes is connected to the two No. 2 heat pipes 201 and the two No. 1 connecting pipes, and the other end of the two No. 2 connecting pipes is connected to the No. 3 heat pipe 301, and a No. 2 solenoid valve A6 and a No. 1 pump group 8 are provided on the upper No. 2 connecting pipe, and a No. 2 solenoid valve B7 and a No. 3 pump group 14 are provided on the lower No. 2 connecting pipe.

[0047] Furthermore, when the temperature of the primary side of the No. 1 heat pipe 101 is greater than the temperature of the primary side of the No. 2 heat pipe 201, the No. 3 heat pipe 301 is closed, and the heat is absorbed by the No. 1 heat pipe 101 and transferred to the No. 2 heat pipe 201 in the room, thereby releasing its heat to achieve the heat exchange function.

[0048] The implementation scenario is specifically as follows: when the present invention is in use, when the temperature of the primary side of the No. 1 heat pipe 101 is greater than the temperature of the primary side of the No. 2 heat pipe 201, the PLC controller 11 will open the two No. 1 solenoid valves and close the two No. 2 solenoid valves, that is, the No. 3 heat pipe 301 in the system at this time does not participate in the work, and the No. 2 pump group 9 on the No. 1 connecting pipe below is opened to make it run in the direction of the No. 1 heat pipe 101 (the No. 1 heat pipe 101 as the steam section can run naturally without power to the No. 2 heat pipe 201; at this time, because the temperature of the No. 1 heat pipe 101 end is greater than that of the No. 2 heat pipe 201 end, the No. 1 heat pipe 101 will perform an evaporation effect, and its steam will enter the No. 2 heat pipe 201 through the No. 1 solenoid valve A4 above, and the heat energy in the No. 2 heat pipe 201 will form a condensation effect when it is cooled; the condensed liquid is transported to the No. 1 solenoid valve B5 through the No. 2 pump group 9 to flow out, and then transported to the No. 1 heat pipe 101, and then evaporated, and circulated continuously, thereby achieving the energy-saving effect of heat exchange;

[0049] When used in summer, assuming that the outdoor temperature is 25°C (the inlet air temperature is 25°C), the energy saving target in summer is: the energy absorbed by the No. 2 heat pipe 201 is released to the No. 1 heat pipe 101 for cooling, reducing the energy consumption of the surface cooling section; the energy absorbed by the No. 1 heat pipe 101 is released to the No. 2 heat pipe 201 for heating, reducing the energy consumption of the heating section (see Figure 1-2 ):

[0050] At this time, the energy for precooling (heat pipe No. 101) is provided by reheating (heat pipe No. 201), and the energy for reheating (heat pipe No. 201) is provided by precooling (heat pipe No. 101) (assuming that the heat exchange effect is 6°C);

[0051] At this time, the No. 1 heat pipe 101 can pre-cool and absorb 6°C energy (25°C→19°C), thereby reducing the electric energy or ice water volume of the surface cooling section (originally 25°C needed to be reduced to 9°C, now only 19°C needs to be reduced to 9°C, reducing 6°C energy consumption); and the No. 2 heat pipe 201 can pre-heat and release 6°C energy (9°C→15°C), thereby reducing the electric energy or steam volume of the heating section (also reducing 6°C energy consumption).

[0052] Refer to the instruction manual Figure 3-4 When the temperature of the primary side of the No. 2 heat pipe 201 is greater than the temperature of the primary side of the No. 1 heat pipe 101 and the temperature of the No. 3 heat pipe 301 is greater than the primary sides of the No. 1 heat pipe 101 and the No. 2 heat pipe 201, the No. 3 heat pipe 301 in the indoor return air area absorbs heat and transfers it to the No. 1 heat pipe 101 and the No. 2 heat pipe 201, which then releases their heat to achieve the heat exchange function.

[0053] The implementation scenario is as follows: when the present invention is in use, when the temperature of the primary side of the No. 2 heat pipe 201 is greater than the temperature of the primary side of the No. 1 heat pipe 101 and the temperature of the No. 3 heat pipe 301 is greater than the primary side of the No. 1 heat pipe 101 and the No. 2 heat pipe 201, the PLC controller 11 will open the two No. 2 solenoid valves and the two No. 1 solenoid valves, and open the No. 3 pump group 14 to make it run in the direction of the No. 3 heat pipe 301 (the No. 3 heat pipe 301 as the steam section can run naturally without power to the No. 1 heat pipe 101 and the No. 2 heat pipe 201, or the No. 1 pump can be added). Group 8 is running); at this time, because the temperature of the end of the No. 3 heat pipe 301 is higher than that of the No. 1 heat pipe 101 and the No. 2 heat pipe 201, the No. 3 heat pipe 301 will perform an evaporation effect, and its steam will enter the No. 1 heat pipe 101 and the No. 2 heat pipe 201 through the No. 2 solenoid valve A6, and the heat energy in the No. 1 heat pipe 101 and the No. 2 heat pipe 201 will be cooled to form a condensation effect; the condensed liquid will flow out through the No. 2 solenoid valve B7, and then be sent to the No. 3 heat pipe 301 through the No. 3 pump group 14, and then evaporate, and circulate continuously, thereby achieving the energy-saving effect of heat exchange;

[0054] When used in winter, assuming that the outdoor temperature is 0°C (the inlet air temperature is 0°C), the winter energy saving goal is: the energy absorbed by the No. 3 heat pipe 301 is released to the No. 1 heat pipe 101 and the No. 2 heat pipe 201 for temperature increase, reducing the energy consumption of the preheating section and the heating section;

[0055] At this time, the energy for preheating (heat pipe No. 101) and the energy for the heating section (heat pipe No. 201) are provided by the indoor higher temperature environment (such as heat pipe No. 301 in the indoor return air zone) (assuming the heat exchange effect is 6°C);

[0056] At this time, the No. 1 heat pipe 101 can preheat and absorb 6°C of energy (0°C→6°C), thereby reducing the amount of electric energy or steam in the preheating section (or heating section) (originally, the temperature needed to be raised from 0°C to 9°C (hypothetical value), now it only needs to be raised from 6°C to 9°C, reducing energy consumption by 6°C), and the No. 2 heat pipe 201 can preheat and absorb energy such as the exhaust duct (9°C→15°C), thereby reducing the amount of electric energy or steam in the heating section (originally, the temperature needed to be raised from 9°C to 20°C (hypothetical value), now it only needs to be raised from 15°C to 20°C, reducing energy consumption by 6°C).

[0057] Refer to the instruction manual Figure 5-6 When the temperature of the primary side of the No. 1 heat pipe 101 approaches the temperature of the primary side of the No. 2 heat pipe 201 and the temperature of the No. 3 heat pipe 301 is greater than the primary sides of the No. 1 heat pipe 101 and the No. 2 heat pipe 201, the No. 1 heat pipe 101 is closed, and the No. 3 heat pipe 301 in the indoor return air zone absorbs heat and transfers the heat to the No. 2 heat pipe 201 to release its heat, thereby achieving the heat exchange function.

[0058] The implementation scenario is as follows: when the present invention is in use, when the temperature of the primary side of the No. 1 heat pipe 101 approaches the temperature of the primary side of the No. 2 heat pipe 201 and the temperature of the No. 3 heat pipe 301 is greater than the primary side of the No. 1 heat pipe 101 and the No. 2 heat pipe 201, the PLC controller 11 will open the two No. 2 solenoid valves and close the two No. 1 solenoid valves, that is, the No. 1 heat pipe 101 in the system does not participate in the work at this time, and the No. 3 pump group 14 is turned on to make it run in the direction of the No. 3 heat pipe 301 (the No. 3 heat pipe as the steam section). 301 to the No. 2 heat pipe 201 can be operated naturally without power, or it can be operated with the No. 1 pump group 8); at this time, because the temperature of the No. 3 heat pipe 301 end is higher than that of the No. 2 heat pipe 201 end, the No. 3 heat pipe 301 will perform an evaporation effect, and its steam will enter the No. 2 heat pipe 201 through the No. 2 solenoid valve A6, and the heat energy in the No. 2 heat pipe 201 will form a condensation effect when it encounters cold; the condensed liquid will flow out through the No. 2 solenoid valve B7, and then be sent to the No. 3 heat pipe 301 through the No. 3 pump group 14, and then evaporate, and the cycle will continue.

[0059] Then the energy-saving effect of heat exchange can be achieved;

[0060] When the temperature on the primary side of the No. 1 heat pipe 101 approaches that on the primary side of the No. 2 heat pipe 201, assuming that the outdoor temperature is 9°C (the inlet air temperature is 9°C), the energy-saving goal at this time is: to release the energy absorbed by the No. 3 heat pipe 301 to the No. 2 heat pipe 201 for temperature increase, thereby reducing the energy consumption of the heating section;

[0061] At this time, the energy of the heating section (No. 2 heat pipe 201) is provided by the higher temperature environment in the room (such as No. 3 heat pipe 301 in the indoor return air zone) (assuming that the heat exchange effect is 6°C);

[0062] At this time, the No. 2 heat pipe 201 can absorb 6°C of energy (9°C→15°C), thereby reducing the amount of electric energy or steam in the heating section (originally 9°C needed to be heated to 20°C (assumed value), now only 15°C is needed to be heated to 20°C, reducing 6°C of energy consumption).

[0063] The PLC controller 11 can control the flow rates of the three pump groups, thereby controlling the heat exchange rate and further controlling the heat exchange temperature.

[0064] The present invention includes at least three groups of heat pipes (filled with refrigerant and other high-efficiency heat flow materials), which are connected to the PLC controller 11 through the electromagnetic valve, pump group, temperature sensor 10 for controlling the flow direction; wherein the PLC controller 11 is connected to at least one group of temperature sensors 10, and is used to receive the ambient temperature, and after processing and analyzing the received ambient temperature, control the switch of each electromagnetic valve for the flow direction, open the valve group, pump group and heat pipe for heat exchange, and thus achieve the effect of heat exchange;

[0065] The heat pipe equipment system that can provide heat exchange has a simple structure. When the outdoor ambient temperature is high, heat can be absorbed through the superheated pipe and transferred to another heat pipe that needs heat, thereby releasing its heat to achieve the heat exchange function; and when the outdoor ambient temperature is low, the heat in the indoor high-temperature environment can be transferred to the low-temperature environment that needs heat through the heat pipe in this environment, thereby achieving the heat exchange function. The present invention can achieve a more efficient energy-saving effect.

[0066] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
