Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to fig. 1 to 9, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that, in the embodiments of the present invention, the directions are shown in the attached drawings. If a particular gesture changes, the directional indication changes accordingly.

Referring to fig. 1 and 2, the cooling system based on the cold-hot balancing machine in the technical scheme comprises a heat exchange device 1 and the cold-hot balancing machine 2; a heat exchange device 1 configured to have a heat exchange body 11, and a condensing mechanism and a cooling branch formed in the heat exchange body 11, the cooling branch including a cooling liquid inlet 13 and a heat exchange liquid outlet 12; the cold and heat balancing machine 2 is configured to have a cold and heat balancing machine body 21, the cold and heat balancing machine body 21 includes a cold source branch and a heat source branch, wherein a cooling output port 22 and a cooling return port 23 of the cold source branch are respectively communicated with the cooling liquid inlet 13 and the heat exchange liquid outlet 12 in a one-to-one correspondence manner to form a cooling loop; the heat source branch is configured to have a heat source output port 24 for outputting a heat source outward and a heat recovery flow back port 25 for recovering an input medium.

That is, in this scheme, cold and hot balance machine 2 is including cold source branch road and heat source branch road, realizes exporting cooling medium and will pass through heat exchange device 1 and realize that the cooling medium after the heat exchange retrieves through the cold source branch road, realizes providing cooling medium to heat exchange device 1 through the cold source branch road of cold and hot balance machine 2 like this. The cooling medium is output by the cold-hot balancing machine 2, so that different temperatures can be output, the influence of the ambient temperature on the temperature of the cooling medium can be avoided, and the cooling efficiency is improved. Meanwhile, the heat source branch receives a medium input from the outside through the heat collecting return port 25, and heats the medium through the operation of the cold and hot balancing machine 2 to output a high-temperature medium, so that the effect of reducing energy consumption is achieved, and a heat source (high-temperature medium) can be provided for external equipment through the heat source output port 24.

It is to be noted, among other things, that the cooling medium in the cooling circuit may be a number of different media, such as water or the like. However, in this embodiment, it is preferable to select cooling oil, because the cooling oil is not easy to freeze, so the cold-heat balance machine 2 can output cooling oil with a low temperature enough to improve the cooling efficiency. Compared with the traditional air cooling and water tower cooling, the cooling medium has very low temperature, so that the cooling efficiency can be greatly improved, and the energy-saving effect can be achieved on the premise of improving the cooling efficiency.

It should be understood that, in the present technical solution, the cold-hot balancing machine 2 may be an existing cold-hot dual-source device, which is capable of collecting heat obtained by a cooling medium in a cooling circuit through heat exchange as a part of energy during operation, and outputting a high-temperature heat source and a low-temperature cold source. Namely, the cold and heat balancing machine 2 obtains the heat source input value of the substance to be cooled through the cold source branch, and outputs a high temperature heat source and simultaneously outputs a low temperature cold source through the cold source branch, and the cold and heat balancing machine 2 is, for example, a double-source cold and hot water machine.

It should be noted that the high-temperature heat source at the heat source output port 24 of the heat source branch can be communicated to a water storage container (not shown), such as a water tank, and the storage of the high-temperature heat source (such as high-temperature hot water) is realized by the water storage container for other uses.

The cooling output port 22 is communicated with the cooling liquid inlet 13 through a working medium pipe, and the cooling return port 23 is communicated with the heat exchange liquid outlet 12 through a working medium pipe; the heat source output port 24 and the heat recovery reflux port 25 of the heat source branch can also be communicated with a working medium pipe; the flow guide of various media is realized through the working medium pipes. In particular, the working medium pipes can be stainless steel pipes. In addition, in order to reduce energy loss, the outer periphery of each working medium pipe can be coated with a heat insulation layer. In order to ensure that the cooling medium sprayed from the spraying mechanism has enough speed and pressure and ensure the spraying quality, a pressure pump 3 is arranged on a working medium pipe communicated with the cooling output port 22 and the cooling liquid inlet 13, and certain pressure is applied to the cooling medium flowing inwards through the pressure pump 3; when the pressure pump is in specific work, the pressure pump 3 can be directly electrified for use.

Specifically, when the heat exchanger is applied, the condensation mechanism of the heat exchanger 1 is directly communicated with an external pipeline needing a substance to be cooled for use; the heat collecting return port 25 of the heat source branch 2 of the cold-heat balance machine 2 heats the medium by inputting the external medium and outputs the heated medium from the heat source output port 24. For example, the heating return port 25 communicates with a water supply device. In other applications, the output port of the condensing mechanism of the heat exchanger 1 is connected to the heat recovery reflux port 25 through a pipeline to appropriately heat the cooled medium and output the medium for other purposes. Of course, the present invention is not limited to this, and may be applied to various fields where a fluid substance to be cooled is cooled, such as a thermal power plant.

Referring to fig. 2, the heat exchange body 11 comprises a shell 111 and a cavity 112 formed in the shell 111, wherein the cavity 112 is internally provided with a condensing mechanism arranged along the axial direction of the cavity 112 and used for conveying a medium to be cooled, and a spraying mechanism communicated with the cooling liquid inlet 13 and used for spraying the cooling medium to different height positions of the condensing mechanism. In this scheme, at first adopt the mechanism that sprays to spray cooling medium and can guarantee colder original cooling medium constantly and condense the mechanism contact to realize and wait to cool off the material and carry out the heat exchange, improve cooling efficiency. Furthermore, the spraying mechanism can spray the positions with different heights of the condensing mechanism, so that cooling at different positions is realized, and a good heat dissipation and cooling effect can be ensured.

The condensing mechanism may be any suitable structure known in the art, such as a helical pipe, which may allow for increased travel within cavity 112 to facilitate rapid cooling.

In detail, in some embodiments, as shown in fig. 3 and 4, the coagulation mechanism includes a main pipe 113 and at least one hollow sphere 114 disposed on the main pipe 113, the main pipe 113 is communicated with the hollow sphere 114, wherein both ends of the main pipe 113 extend to the outside of the housing 111, respectively. It should be understood that the hollow spheres 114 have a relatively large surface area, and therefore the hollow spheres 114 are provided on the main pipe 113, thereby increasing the contact area of the medium to be cooled while flowing in the condensing mechanism, which facilitates sufficient heat exchange between the cooling medium and the substance to be cooled. The technology is particularly suitable for cooling the substance to be cooled by high-temperature gas. The gas can thus easily flow over the hollow spheres 114 while flowing over the main pipe 113 and exchange heat with the cooling medium at the inner wall, and after cooling to liquefy to a water liquid, flows rapidly down along the inner wall of the main pipe 113.

Specifically, the main pipe 113 passes through the upper end surface and the lower end surface of the housing 111 and extends to the outside, that is, the main pipe 113 is arranged coaxially with the central axis of the cavity 112, so that the main pipe 113 is centered, which is beneficial to setting a hollow sphere 114 with a larger diameter so as to increase the surface area.

Correspondingly, the housing 111 includes a cover 117, and the cover 117 is used for closing the upper opening of the housing 111. In order to meet the requirement that the main pipe 113 extends towards the upper end, through holes are designed corresponding to the middle position of the cover 117 and the central position of the bottom of the shell 111, and two ends of the main pipe 113 are in sealing fit with the corresponding through holes and extend to the outer side.

It should be understood that the number of hollow spheres 114 on the main tube 113 is set according to the depth of the cavity 112 and the heat dissipation requirements.

In order to ensure good cooling efficiency, it is necessary to increase the diameter of the hollow sphere 114 as much as possible. In this embodiment, the diameter of the hollow sphere 114 is between one half and four fifths of the diameter of the cavity 112. Preferably, the diameter of the hollow sphere 114 is equal to four-fifths of the diameter of the cavity 112, so as to ensure that the hollow sphere 114 has enough surface area and also ensure that there is enough clearance between the hollow sphere 114 and the inner side wall of the housing 111, so that the cooling medium sprayed by the spraying mechanism can rapidly flow towards the bottom of the cavity 112 to take away heat. Of course, the diameter of the hollow sphere 114 can be anywhere between one-half to four-fifths.

When the cavity 112 is circular in cross-section, the gap between the hollow sphere 114 and the sidewall of the cavity 112 is fixed; when the cross-section of the cavity 112 is square, the diameter of the hollow sphere 114 is between one half and four fifths of the smallest dimension of the sides of the cross-section of the cavity 112. That is, when the cross-section of the cavity 112 is square, the diameter of the hollow sphere 114 is between one-half to four-fifths of the side length of the cross-section of the cavity 112; when the cross-section of the cavity 112 is rectangular, the diameter of the hollow sphere 114 is between one-half to four-fifths of the width of the cross-section of the cavity 112. Hollow sphere 114 should not contact the side walls of cavity 112 so as to avoid the accumulation of cooling medium where contact occurs.

In some embodiments, the outer peripheral surfaces of the main tube 113 and the hollow sphere 114 are non-specular. Because of the non-mirror surface, a time delay effect is generated on the flow of the cooling medium, namely, the time for the cooling medium to flow on the outer surface of the main pipe 113 and the surface of the hollow sphere 114 is longer than that of the mirror surface, so that the cooling medium is beneficial to carrying out sufficient heat exchange with the internal substance to be cooled. Specifically, the outer peripheral surfaces of the main pipe 113 and the hollow sphere 114 are frosted surfaces. The frosted surface has the bumps and the pits with the unevenness, so that a time delay effect is generated on the cooling medium. In a specific application, the main tube 113 and the hollow sphere 114 may be an integrated structure formed by using a 3D printing technology, and it is known that the surface of a 3D printed product is non-mirror-surface, and the non-mirror-surface design effect can be achieved by using such a technology. Meanwhile, 3D printing is adopted, the main pipe 113 and the hollow sphere 114 can be conveniently machined, and the cost is lower.

Referring to fig. 5, the spraying mechanism comprises a flow guide pipe 115 and a plurality of spray pipes 116 which are not less than the number of hollow spheres 114, the spray pipes 116 are communicated with the flow guide pipe 115, and each spray pipe 116 is arranged around the axis of the main pipe 113; wherein the draft tube 115 comprises the cooling liquid inlet 13; the nozzle 116 has a plurality of nozzles 1161 facing the main pipe 113 and the hollow sphere 114 along the circumferential direction. That is, in the present embodiment, the spray pipes 116 are arranged around the axial center line of the main pipe 113 to spray the main pipe 113 and the hollow sphere 114. The duct 115 is communicated with the cooling output port 22 of the cooling/heating balancer body 21, and the cooling medium generated by the cooling/heating balancer body 21 flows into the duct 115 and is ejected outward by the nozzle 116. The main pipe 113 and the hollow ball 114 can be effectively sprayed by a spraying mode so as to realize that the spraying at different positions can ensure good heat exchange with a cooling medium. Meanwhile, when a plurality of spray pipes 116 are arranged, the main pipe 113 and the hollow ball 114 can be sprayed at different height positions. Specifically, the draft tube 115 communicates with a plurality of (two or more) spray pipes 116, and the plurality of spray pipes 116 are disposed at different positions along the axial center line of the main pipe 113, so that spraying at different positions can be performed.

As shown in fig. 5, the nozzle 116 has a circular ring shape. In other embodiments, the nozzle 116 may be in the shape of a fork with a notch, as shown in fig. 6, that is, the nozzle 116 is composed of tubes with circular arc shapes on the left and right sides.

It is important to note that in the present embodiment, the inner side surface of the nozzle 116 has a plurality of injection holes 1161 arranged along the circumferential direction in cross section, and each injection hole 1161 is opened along the radial direction. As shown in fig. 7, three injection holes 1161 are provided, including three upper, middle and lower in the drawing, wherein the middle one is provided laterally, the upper one is arranged toward the upper right, and the lower one is provided toward the lower right, so that an injection region is formed when the cooling medium is injected, as shown in the right side of fig. 7. Of course, the number of the injection holes 1161 arranged in the cross-sectional direction is not limited to three, and may be four, five, six or even more, and may be set according to the diameter of the hollow sphere 114. More orifices 1161 are provided when the diameter is larger.

In other embodiments, as shown in fig. 8, it is preferable to include at least one more nozzle 116 than the hollow spheres 114, and each of the upper and lower portions of the hollow spheres 114 has one nozzle 116. That is, the number of the spray pipes 116 is larger than that of the hollow spheres 114, and by arranging one spray pipe 116 at the vicinity of the upper and lower parts of the hollow spheres 114, both the upper and lower parts of the hollow spheres 114 can be sprayed with the cooling medium, and the substance to be cooled and the cooling medium can be rapidly heat-exchanged at the hollow spheres 114. Of course, besides, the number of the nozzles 116 can be set according to the overall height of the main pipe 113, and specifically, one nozzle 116 can be set according to a specific distance, so that any method of tightly changing the number of the nozzles 116 and simply rearranging the positions of the nozzles 116 is within the scope of the present invention.

In addition, in this embodiment, the heat exchange liquid outlet 12 is located at the bottom of the cavity 112. This scheme is favorable to the cooling medium to flow out and flow back to in cold and hot heat balance machine body 21 after carrying out the heat transfer.
