Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a type of bubble circulation heat exchange device, and in particular, it promotes stable and convenient heat exchange in a closed liquid pipe by a method of generating heat cold flow.
The present invention relates to a bubble circulation heat exchange device.

2. Description of the Related Art A well-known heat pipe type radiator has one sealed vacuum cavity, which is filled with an appropriate amount of working fluid, and a plurality of heat dissipation fins are provided above the cavity.
A wick structure section is provided in the cavity. The working principle is that one end of the cavity is heated to boil and evaporate the working fluid, causing the hot zone on one side of the tube to flow toward the cold zone on the other side, and then the gas in the cold zone. Is cooled to form a liquid, and the liquid is returned by gravity or capillary force.

Therefore, due to the restriction of the capillarity of the structure in the heat pipe, a dry-out phenomenon may occur at the time of excessive heating, a dry-out state occurs, a liquid recirculation is eliminated, and the inside of the heating zone is entirely closed. It becomes a high temperature gas, and only the gas phase exists, so that the temperature rises sharply and the heat superconductivity (heat superc) in the heat pipe is increased.
The phenomenon of "onduction" has failed, and the effect of use has been greatly reduced. In addition, heat pipes require a high degree of degassing, and without them, superconducting properties were greatly affected. Moreover, when the vehicle bent or moved with respect to the operation angle, it became impossible to drive smoothly. For this reason, the heat pipe has a defect that it is not possible to compensate for the innate defect and the acquired ataxia, and therefore, a further smooth heat exchange device has been demanded.

FIG. 1 is the simplest embodiment, consisting of a heat source 1 and a fluid circuit 2, with a liquid 3 in the fluid circuit 2.
The radiator is the body of the fluid circuit 2. The difference between the embodiment shown in FIG. 2 and the embodiment shown in FIG. 1 is that one radiator 5 is added. The difference between FIG. 3 and FIG. 1 is that the bubble generator 6 is additionally installed near the heat source 1 in the fluid circuit 2. The difference between FIG. 4 and FIG. 2 is that the bubble generator 6 is additionally installed. The difference between FIG. 5 and FIG. 3 is that an expansion area 4 where bubbles are generated is provided in the fluid circuit 2. The difference between FIG. 6 and FIG. 4 is that
The expansion area 4 in which bubbles are generated is provided in the fluid circuit 2. The difference between FIG. 7 and FIG. 1 is that the fluid circuit 2
Since the expansion area 4 connected to the above is provided, the fluid circuit 2 is filled with the liquid 3, and the expansion area 4 for gas and bubbles is formed.

The difference is that an expansion chamber 40 connected to the fluid circuit 2 is provided. The difference between FIG. 9 and FIG. 7 is that
The bubble generator 6 is added near the heat source 1.
The difference between FIG. 10 and FIG. 8 is that the bubble generator 6 is added near the heat source 1. Comparing FIG. 11 and FIG. 6, the fluid circuit 2 is extended infinitely and the inlet 7 is provided, which is the next essential element. What is most important is another idea of the present invention shown in FIG. In FIG. 12, two fluid circuits are provided, one of which is in direct contact with the heat source 1, and the heat source 1 in this fluid circuit 2 is composed at multiple points. The heat radiator 8 of the fluid circuit 2 is used as the heat conductor 8, the heat conductor 8 conducts heat to the other fluid circuit, and the heat radiator 5 of the other fluid circuit achieves heat radiation, thus standardizing. Completed the skewered form, convenient for production and assembly, no special circuit is required. Further, a form in which a plurality of circuits connected in parallel to the same heat source are combined is also possible.

For the fluid in the fluid circuit 2, an appropriate substance is selected according to the operating temperature and pressure, and whether the fluid is evacuated and evacuated or not evacuated and evacuated in the circuit depends on the type of fluid used or operation Determined by temperature range. In addition, the body of the circuit has various shapes, outer shapes, materials, or combinations thereof, and has rigidity, flexibility, or a combination thereof, and skewer connection, parallel connection, net shape, independent,
It may be in the form of multiple circuits or any combination thereof.

The heat radiator may be a body of the circuit, or may be provided at a heat exchange progressing portion of the circuit, and the heat radiator may be connected to various known heat dissipation devices to promote heat exchange.

The bubble generator is a device for generating bubbles.
It may be an inner wall of a circuit cross section of various shapes, or may be an insert of various shapes provided in the circuit, and may be a connecting portion of pipe diameters of different sizes, or series, parallel, or It is composed of a mesh circuit. The expansion area in the circuit is the expansion or contraction of the vapor space.
Is defined as an internal space in an appropriately sized circuit, an area not filled with liquid in the fluid circuit 2, or added to the circuit (see FIGS. 7 to 10). A device which can be expanded and contracted by an appropriate pressure, and the liquid does not need to completely fill the entire circuit, and naturally has no expandable area. In this way, even if the liquid in the circuit expands due to the temperature rise, there is a storage space, so that the circuit will not be damaged by explosion.

The heat source of the circuit is suitably joined to the circuit in a variety of well known ways to facilitate heat transfer.
Further, the bubble generator in the circuit of the various forms described above can be installed in the heat source, and even when brought into contact with the circuit, the same effect of generating bubbles can be achieved. In the meantime, they are connected by any suitable method, for example, mechanical means such as gluing, welding, riveting, locking, or a combination of these methods.

The body of the circuit is provided with means for injecting fluid into the device and sealing it, and the injection port and the sealing method can be changed according to the outer shape of the circuit, but only the whole circuit can be closed after the liquid is injected. The injection port is provided at an appropriate position, and since it is a line type circuit, each contact is always sealed to prevent liquid leakage.

In the apparatus of the present invention, a plurality of sets can be connected in parallel or in series so that continuous heat exchange proceeds. Finally, the thermal equilibrium of the entire equipment system (thermal equi)
librium). The heat source may be a heating device, and the heat radiator may be a heat radiation device corresponding to the heating device. The heat conduction medium during that time is liquid, and the driving force for circulation generation is gas, and when the circuit system is in an equilibrium still cooling state, heat is directly or indirectly absorbed by the bubble generator by the heating device or heat source to generate bubbles. It is generated and drives the circuit system to flow in the unbalanced direction to generate continuous circulation rotation in the circuit, and the other side circuit advances heat dissipation and cooling of the liquid gas, and returns to the heating point after heat dissipation. The heat exchange operation of the next heat circulation is performed by allowing the liquid to flow, and thus sufficient cold heat exchange is promoted. However, the dryout phenomenon due to overheating that occurs in the well-known heat pipe and the situation of effect loss due to it do not occur. This is because a large amount of liquid is put in the circuit of the present invention, which is different from the small amount of liquid in the heat pipe. Known heat pipes have limited wicks and operating angles, but the circuit of the present invention can be installed for very long periods and can have too many radiators installed, i.e. the heat source requires some heat rejection. Even in the case, it is possible to solve the problem by operating an appropriate heat radiator and exchanging heat. This heat radiator can be installed at the same position or at an external position, and it can also be used as the body of the circuit, and it is also possible to transfer heat from one place to another place in the circuit to promote heat exchange. Is. Therefore, heat can be conducted to the far end, and circuits can be folded, aligned, and stacked. All of these are structures that could not be achieved by known techniques.

[0016]

The present invention has a heat exchange drive type in which heat circulation proceeds by means of a simple circuit.
It can be applied to many structures up to large power plants, and is a structure that is considerably suitable for use in heat flow conduction.
