Description

Technical Field

[0001] The utility model relates to a heat exchanger, in particular to a gravity heat pipe heat exchanger. Background Art

[0002] A gravity heat pipe heat exchanger is a device that uses the temperature difference and gravity between indoors and outdoors for heat exchange. Its structure mainly consists of a box body, internal and external fans, an evaporator, a condenser, connecting pipelines, a control board assembly, etc. When the device is in operation, the refrigerant evaporates and absorbs heat in the evaporator on the indoor side and becomes gaseous, thereby taking away heat. The gaseous refrigerant enters the condenser on the outdoor side through the pipeline. Since the outdoor temperature is relatively low, the refrigerant condenses and releases heat to become liquid, transferring the heat to the outdoor air. At the same time, the liquid refrigerant flows into the evaporator on the indoor side under the action of gravity and continues to evaporate and absorb heat, so as to cycle heat exchange, thereby achieving the purpose of heat dissipation and cooling. However, due to the small height and thickness dimensions of the gravity heat pipe heat exchanger in the prior art, especially the very small width, only one fan can be accommodated on one side of the gravity heat pipe heat exchanger, and there may be a situation of insufficient air volume, making it impossible to evenly blow the air volume onto the surfaces of the evaporator and the condenser; in addition, when a single fan fails and cannot work, heat exchange cannot be cycled, resulting in the failure of the device. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a gravity heat pipe heat exchanger that can ensure sufficient and uniform air volume.

[0004] The technical solution adopted by the utility model is as follows: The utility model includes a housing, an inner circulation chamber and an outer circulation chamber are separated in the housing. The inner circulation chamber includes a first air inlet chamber and a first air outlet chamber. The first air outlet chamber communicates with the lower end of the first air inlet chamber. An evaporator is arranged in the first air outlet chamber. The outer circulation chamber includes a second air inlet chamber and a second air outlet chamber. The second air outlet chamber communicates with the upper end of the second air inlet chamber. A condenser is arranged in the second air outlet chamber. The evaporator is communicated with the condenser. The position of the condenser is higher than that of the evaporator. First fans and second fans with staggered distribution are arranged in both the first air inlet chamber and the second air inlet chamber.

[0005] Further, an air duct partition is arranged between the first fans and the second fans.

[0006] Further, an intermediate partition is arranged between the inner circulation chamber and the outer circulation chamber.

[0007] Further, the intermediate partition includes a first partition, a second partition, and a third partition. The first partition is located above the second partition. Both the first partition and the second partition are vertically arranged. The third partition is inclined. The upper end of the third partition is connected to the lower end of the first partition, and the lower end is connected to the upper end of the second partition.

[0008] Further, both the evaporator and the condenser are inclined.

Both of the two output pipes are connected to the upper end of the condenser, and both of the two input pipes are connected to the lower end of the condenser.

[0010] The beneficial effects of the present utility model are as follows:

[0011] Compared with the deficiencies of the prior art, in the present utility model, by arranging the first fan and the second fan with staggered distribution in both the first air inlet chamber and the second air inlet chamber, it is possible to place two fans in a relatively small space, thereby meeting the air volume requirements and improving the effect of circulating heat exchange. Therefore, two fans can be arranged in both the inner circulation chamber and the outer circulation chamber, so that the air volume can be sufficient and evenly blown onto the surfaces of the evaporator and the condenser.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

If the specific posture changes, the directional indications will also change accordingly.

[0022] In addition, the descriptions involving "first", "second", etc. in the present utility model are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0023] Such as Figures 1 to 4As shown in the figure, in this embodiment, the utility model includes a housing 1. An inner circulation chamber 2 and an outer circulation chamber 3 are separated in the housing 1. The inner circulation chamber 2 includes a first air inlet chamber 5 and a first air outlet chamber 6. The first air outlet chamber 6 communicates with the lower end of the first air inlet chamber 5. An evaporator 7 is arranged in the first air outlet chamber 6. The outer circulation chamber 3 includes a second air inlet chamber 8 and a second air outlet chamber 9. The second air outlet chamber 9 communicates with the upper end of the second air inlet chamber 8. A condenser 10 is arranged in the second air outlet chamber 9. The evaporator 7 is communicated with the condenser 10. The position of the condenser 10 is higher than that of the evaporator 7. First fans 11 and second fans 12 with staggered distributions are arranged in both the first air inlet chamber 5 and the second air inlet chamber 8.

[0024] It should be noted that the outer circulation chamber 3 communicates with the cold air outside to conduct outer circulation; the inner circulation chamber 2 communicates with the cabinet or computer room to achieve inner circulation. Specifically, the outer circulation refers to the flow path of external air. The cold air outside enters the outer circulation chamber 3 from the second air inlet chamber 8 and flows from bottom to top to sequentially pass through the condenser 10 and the second air outlet chamber 9, so that the cold air can absorb the heat of the condenser 10 and then be discharged into the ambient atmosphere; the inner circulation refers to the flow path of the air inside the cabinet. The hot air flowing out of various heat-generating electronic devices in the cabinet enters the inner circulation chamber 2 from the first air inlet chamber 5 and flows from top to bottom to sequentially pass through the evaporator 7 and the first air outlet chamber 6, so that the hot air can transfer heat to the evaporator 7. The air after releasing heat is cooled, and the cooled air flows out and is inhaled into various electronic devices again. Among them, since the evaporator 7 is communicated with the condenser 10 and the position of the condenser 10 is higher than that of the evaporator 7, the liquid refrigerant in the condenser 10 can flow to the evaporator 7 due to the action of gravity, and the gaseous refrigerant in the evaporator 7 can enter the condenser 10. Therefore, the inner and outer circulation air respectively and independently exchange heat through the gravity heat pipe heat exchange, effectively preventing external dust and moisture from entering the cabinet or computer room, and ensuring that the cabinet or computer room can have a suitable temperature and cleanliness.

[0025] Compared with the deficiencies of the prior art, in the utility model, by arranging first fans 11 and second fans 12 with staggered distributions in both the first air inlet chamber 5 and the second air inlet chamber 8, it is possible to place two fans in a smaller space, thereby meeting the air volume requirements and improving the effect of cyclic heat exchange. Therefore, two fans can be arranged in both the inner circulation chamber 2 and the outer circulation chamber 3, so that the air volume can be sufficient and evenly blown onto the surfaces of the evaporator 7 and the condenser 10; moreover, since two fans are arranged in both the first air inlet chamber 5 and the second air inlet chamber 8, it is possible to avoid the situation where a single fan cannot work after failure, making the utility model have the advantages of ensuring sufficient air volume and uniform air volume.

[0026] As Figure 2 shown, in some embodiments, a duct partition 13 is provided between the first blower 11 and the second blower 12. Specifically, by providing the duct partition 13 between the first blower 11 and the second blower 12, the air volume of each blower can evenly reach the surfaces of the evaporator 7 and the condenser 10, and the performance will be better.

[0027] As Figures 3 to 4 shown, in some embodiments, a middle partition is provided between the inner circulation chamber 2 and the outer circulation chamber 3; the middle partition includes a first partition 16, a second partition 17 and a third partition 18. The first partition 16 is located above the second partition 17. The first partition 16 and the second partition 17 are both vertically arranged. The third partition 18 is inclined. The upper end of the third partition 18 is connected to the lower end of the first partition 16, and the lower end is connected to the upper end of the second partition 17.

[0028] As Figures 3 to 4 shown, in some embodiments, both the evaporator 7 and the condenser 10 are inclined; two output pipes 19 are connected to the upper end of the evaporator 7, and two input pipes 20 are connected to the lower end of the evaporator 7. Both of the two output pipes 19 are connected to the upper end of the condenser 10, and both of the two input pipes 20 are connected to the lower end of the condenser 10. Specifically, by arranging both the evaporator 7 and the condenser 10 in an inclined manner, the air has a sufficiently large heat exchange area when passing through the evaporator 7 or the condenser 10, thereby improving the heat exchange efficiency; in addition, the liquid refrigerant in the condenser 10 flows into the evaporator 7 through the two input pipes 20, and the gaseous refrigerant in the evaporator 7 enters the condenser 10 through the two output pipes 19.

[0029] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
