Problems solved by technology

The outstanding disadvantage is that it requires energy consumption, resulting in a complex structure, the rotation of the fan or the circulation of the cooling fluid, so there is noise, leakage, etc., and the life span is also limited by time

Embodiment 1

[0065] Embodiment 1, on the outer casing of the heat source body, a number of thin tubes with good thermal conductivity are vertically inserted, which are called temperature difference driven adaptive heat transfer tubes. This type of straight tube can also be called straight-through type. Temperature-difference-driven adaptive heat transfer tube; it can also be used as a through-type fastening bolt, heat source body mounting bracket, etc.; under the condition that the gas can circulate in the tube, the shape is not limited to the round tube, and can be oval, square, Straight-through or curved, deflected tubes of various shapes such as polygons, and even flexible telescopic tubes.

[0066] Its basic principle see figure 1 shown.

[0067] A place close to or directly in contact with the heat source body is selected in advance, and several straight-through temperature difference driven adaptive heat transfer tubes with good thermal conductivity are vertically inserted.

[0068...

Embodiment 2

[0079] Example 2, see image 3 ,

[0080] The integrated self-adaptive heat transfer tube is divided into upper and lower parts, the purpose is to increase the diameter of the upper tube, and the lower part forms a throttling part; the upper and lower parts can also be nested with each other, which is embodied as a sleeve connector 5, which constitutes a The improved expanded heat transfer tube is to change the diameter of the upper exhaust port 4 to make it expand larger under the condition that the caliber of the lower air intake port 3 remains unchanged.

[0081] After expanding the shape of the upper part, the lower part and the upper part are formed with an enlarged cavity structure, so that the outside air sucked from the lower part first goes up a short path through the throttle tube, and then expands in the expanded cavity to form a low-pressure environment, which enlarges the air volume. The distance between the molecules also increases the gravitational force betwee...

Embodiment 3

[0090] Example 3, such as Figure 5 As shown, the surface of the upper extended outer layer of the adaptive heat transfer tube is changed to black, that is, blackening the outer layer 6 is conducive to absorbing more heat from the surrounding environment and the inside of the casing, resulting in the air flowing through the adaptive heat transfer tube As the temperature increases further, the thermal convection self-circulation effect is further strengthened;

[0091] 3. In addition to increasing the number of adaptive heat transfer tubes, another way to increase the heat dissipation area is to roughen the outer surface. The specific method is to roughen the outer surface of the self-adaptive heat transfer tube to present a fine, uneven outer surface. The height of the bumps is comparable to the wavelength of the thermal radiation.

[0092] Therefore, the outer surface of the self-adaptive heat transfer tube can also form a blackened and concave-convex outer layer.

Abstract

The invention discloses a temperature-difference-drive-type self-adapting heat transfer pipe. A plurality of self-adapting heat transfer pipes with good heat conductivity are inserted vertically in a through mode in advance, and are used for receiving heat flow generated by heat source bodies, thus the density of the gas in the pipe is decreased because of expansion by heating, and the gas rises automatically so as to form the heat convection effect; the higher the temperature is, the greater the self circulation of heat convection is, and the effect is self-adaptive; after the measures that heat absorption is increased through blackening the surface, the temperature of gas passing through is lowered through manufacturing an expanded cavity structure, the heat transfer quantity is increased through coarsening disposal inside and outside, the rate of discharge is improved through painting a radiating layer on the inner layer of the pipe, the heat energy is converted into sound energy and the like are implemented, the heat transfer effect is intensified; the temperature-difference-drive-type self-adapting heat transfer pipe has the whole advantages of passive heat radiation, and has partial advantages of initiative heat radiation; especially the structure is simple, energy is not dissipated, and a converse heat accumulation function can also be realized; and the temperature-difference-drive-type self-adapting heat transfer pipe is suitable for heat transfer of a seal body and places which require heat source insulation and magnetic field interference interdiction.

Description

technical field [0001] The invention relates to a natural heat exchange device. Background technique [0002] The heat dissipation methods of objects mainly include heat conduction, heat radiation and heat convection. [0003] 1. When the heat sink is in direct contact with the heat source body, the heat accumulated on the heat source is directly transferred to the heat sink, which is heat conduction. It is basically achieved through physical direct contact between objects, such as when the heat source body is in direct contact with objects (such as support frames, containers, etc.) that are cooler than the body temperature, heat is transferred to these objects. [0004] Heat conduction equation between two different media: q=αA(T2-T1)…………(I) [0005] α is the thermal conductivity coefficient. After the heat dissipation material, shape and air composition are determined, it is related to the air velocity on the surface of the radiator; A is the contact area between the hea...
