The technical scheme provided by the embodiment of the invention relates to a heat pipe type efficient heat exchanger, in particular to the technical field of heat exchange. In the related art, low-level thermal energy utilization represented by ground source heat pumps and air source heat pumps has been increasingly common in the years. A large amount of energy is saved. In the heat transfer of the energy level, the heat exchange is between liquid and liquid due to low temperature and small temperature difference, so that the heat exchange efficiency is generally low.

The interior of the heat pipe 201 is pumped to a negative pressure state and filled with a proper amount of liquid, and the liquid has a low boiling point and is easy to volatilize. The tube wall has a wick that is constructed of a capillary porous material. When one end of the heat pipe 201 is heated, the liquid in the capillary tube is rapidly vaporized, the vapor flows to the other end under the power of heat diffusion, and is condensed at the cold end to release heat, and the liquid flows back to the evaporation end along the porous material by capillary action, and the circulation is not stopped until the temperatures at the two ends of the heat pipe 201 are equal (at the moment, the heat diffusion of the vapor stops). The circulation is performed rapidly, heat can be conducted continuously to the evaporation section of the heating heat pipe 201, the working liquid in the pipe core is heated to evaporate and take away heat, the heat is latent heat of evaporation of the working liquid, the steam flows to the condensation section of the heating heat pipe 201 from the central channel and condenses into liquid, latent heat is released, and the liquid flows back to the evaporation section under the action of capillary force. In this way, a closed cycle is completed, thereby transferring a large amount of heat from the heating section to the heat dissipation section. When the heating section is at the bottom, the cooling section is at the top, and the heat pipe 201 is vertically placed, the back flow of the working liquid can be satisfied by gravity without a wick with a capillary structure, and the heat pipe 201 without a porous wick is called a thermosiphon.

Further, the mounting member includes an inner wall tube 401 disposed in the outer tube 302, a partition 402 disposed in the inner wall tube 401, and a supporting plate 403 disposed at a lower end of the inner wall tube 401, wherein a closed heating zone is defined by the tube wall of the inner wall tube 401, the partition 402, and the supporting plate 403, and it should be further noted that the water inlet tube 202 is used to deliver hot water into the heating zone, and the water in the heat pipe 201 is heated to boil and changed from liquid water phase to steam according to the heat exchange principle.
Preferably, the lower ends of at least one group of heat pipes 201 respectively penetrate through the surface of the partition 402 and extend into the heating area, and it should be further noted that the surface of the partition 402 forms a mounting hole 404 for inserting the heat pipe 201.
Preferably, the partition 402 is a planar plate structure, and it should be further noted that the partition 402 is a circular planar plate structure, and the height of the plane where the upper port of the inner wall tube is located is higher than the height of the plane where the circular planar plate structure is located, so that the cooling water can stay in the area enclosed by the circular planar plate structure and the inner wall tube for a certain time, and sufficiently exchange heat with the low-temperature steam in the heat pipe 201, thereby enhancing the heat exchange effect.
In the example, one end of the water inlet pipe 202 is communicated with the inside of the heating zone of the inner wall pipe 401 of the mounting part, and the other end thereof extends out of the shell; one end of the water outlet pipe 203 is communicated with the inside of the heating area of the inner wall pipe 401, and the other end thereof extends out of the outer shell, and it should be further noted that the lower end of the heat pipe 201 extends into the heating area until the heat pipe 201 is inserted into 1/3 of the length thereof, and the joint of the heat pipe 201 and the partition plate 402 is welded firmly without water leakage.
Preferably, each group of heat pipes 201 is arranged in a rectangular or annular shape, wherein each group of heat pipes 201 arranged in a rectangular shape is arranged at the intersection of the diagonal lines; each set of heat pipes 201 arranged in a circular pattern is concentric, and it should be further noted that the 2/3 pipes of the heat pipes 201 arranged in a rectangular or circular pattern heat the cold water more than the cold water entering from the upper circulating cold water pipe 101.
In the example, the outer pipe 302 and the inner wall pipe 401 are coaxially arranged, and an annular flow guide area 5 for guiding cooling water is formed between the outer pipe 302 and the inner wall pipe 401, it should be further noted that the water output of the lower circulating cold water pipe 102 is smaller, so that the contact exchange time between the cooling water and the heat pipe 201 is longer, the annular flow guide member can be installed or directly detached, and the flexible disassembly and assembly can be performed according to the actual purpose and the planning efficiency of cooling.
Example two, as shown in fig. 4 to 5:
in the technical solution, the partition 402 is an arc-shaped groove structure, and it should be further noted that the length of the heat pipe matched with the arc-shaped groove structure is reduced along with the arc of the arc depression, so as to ensure that all welding positions of the heat pipe and the arc-shaped groove structure are 1/3 positions of the heat pipe, the partition 402 is a hemispherical groove structure with a circular upper opening, and the hemispherical groove structure can store cooling water in the hemispherical groove structure and fully exchange heat with low-temperature steam in the heat pipe 201, so as to enhance the heat exchange effect.
Example three, as shown in fig. 6 to 7:

The device adopts a structure that the heat pipe bundles are arranged, so that heat exchange is carried out between liquid and vapor phases, thereby greatly improving the heat exchange efficiency and greatly reducing the volume of the heat exchanger. The heat exchanger can be directly arranged on a proper circulating water pipeline without being led out by a pipeline, so that the structure is simplified, and the redundant heat loss is reduced. Theoretically, it can be known that, when the absolute pressure in the heat pipe 201 reaches 0.03MPA, the heat exchange efficiency can be improved by 8.1 times, and when the absolute pressure in the heat pipe 201 reaches 0.003MPA, the heat exchange efficiency can be improved by 24.3 times. Therefore, with the heat pipe structure, the same heat exchange effect can be achieved only by using the heat exchange area of 1/24.
