This can lead to permanent damage that may render the device unusable. Problems may arise. Therefore, cooling electro-mechanical systems is important. It is a research area. In existing systems or in current systems developed with evolving technology, In the context of cooling, different methods are generally based on natural convection or forced convection.

Another aim of the invention is to accelerate steam through main steam channels with expanding cross-sections. The reason why steam rises is because the volume in the upper region is less compared to the lower region. triggering of pressure imbalance within the system and thermal energy being released to the external environment 20 Due to this, the fluid condenses and turns into liquid phase, in addition to gravity and capillary force. As a result of the increasing pressure imbalance, it returns to the lower region (evaporator region). by ensuring its rotation, the flow circulation and therefore the cooling performance is improved.

The known characteristics of the technique... In steam rooms used in this situation, the thermal energy taken from the working fluid bottom is 25. As a result, it evaporates and is subjected to buoyant forces across a wide cross-section. It moves upwards. The fluid, moving away from the region where heat is absorbed, transfers the absorbed heat to the upper region. It transfers heat from the layer to the external environment and is placed along the side walls and is called a wick. From a porous structure like a given sieve, it returns to the lower region in the liquid phase. The technique In steam rooms used in their known state, the evaporation of the fluid and 30 The upward movement of the evaporating fluid occurs in a massive form, with a wide and constant cross-section. This occurs in the region. Therefore, the rate of evaporation or the mass movement of vapor... The speed is relatively low, which reduces cooling capacity. Furthermore, the technique... In steam rooms used in their known form, the wick is placed along the side walls. 11 This situation affects both the amount of fluid that needs to return to the lower region in the liquid phase. It also limits the contact surface between opposing vapor and liquid flows. by creating drag / friction losses, reduced flow velocity, drag the formation of the limit, the re-evaporation of a portion of the fluid in the liquid phase, or This causes the liquid to mix into the vapor stream in the form of droplets. (See 5 above) The reasons stated explain the cooling systems of steam chambers used in the known state of the technology. This limits their capacities. Therefore, the evaporating fluid or the formed fluid... Counter-directional vapor, which causes vapor bubbles to accelerate and leave the surface. where the fluid flows do not come into contact with each other, the fluid that transforms into the liquid phase is at a higher level. it can reach the lower region easily and in sufficient quantity, in addition to capillary force, the upper 10 also due to the effect of pressure imbalances triggered by volumetric differences between the region and the sub-region New designs for cooling systems that support the movement of fluid in the liquid phase. and / or techniques are needed. In this context, a new type of thermal energy driven system is required. Portable passive cooler; capillary effect with expanding cross-section main vapor channels.

This improves the process, resulting in a smaller volume in the upper region compared to the lower region. This triggers pressure imbalances and releases thermal energy to the external environment. Due to this, the fluid condenses and turns into liquid phase, in addition to gravity and capillary force. as a result of pressure imbalances triggered within the system, it returns to the lower region 25 by ensuring its rotation, the flow circulation and therefore the cooling performance Its improvement, unlike conventional wick structures, is that the main working fluid is in liquid state.

Mini / micro channels Description of the invention: 5 The subject of the invention is a new type of portable passive cooler (100) driven by thermal energy, volume built-in or portable electric vehicles that have limitations and require quiet operation temperature control in mechanical systems and thus the safety of the related systems. The invention provides a new type of portable passive cooler driven by thermal energy. (100), as basic components, body (110), lid (120), filling / emptying port 10 (121), filling / draining port plug (130), main flow part (140) and refrigerant (SA) is formed. The refrigerant (SA) is thermally transferred through the filling / emptying port (121). internal volume of a new type of portable passive cooler (100) powered by energy After being vacuumed, it is filled to 20-30% of its internal volume. Closed and To obtain a leak-proof interior environment, the filling / emptying port (121), 15 The filling / draining port is closed with a plug (130). It operates as refrigerant (SA). Any coolant suitable for the temperature and the type of materials that make up the system. The fluid (such as water, ethanol, methanol, R134a) can be used. The bottom surface of the body (110) It is placed on the component that needs to be cooled. Body (110) material Metals with high thermal conductivity coefficients such as copper, silver, aluminum, and brass are preferred. It will provide an advantage. In the lower region (150) initially in liquid form A refrigerant (RC) evaporates due to the effect of heat removed from the component to be cooled. and it begins to boil, turning into vapor. Because a phase change has occurred. The amount of heat extracted from the component to be cooled is sufficient for single-phase cooling systems. It is considerably higher in comparison. The resulting vapor bubbles are located in the main flow part (140) 25 The area rises rapidly in the main steam channels (170) with wide cross-sections to the upper region (160) reaches. The main steam channels (170) are in an upwardly widening cross-section. the steam formed accelerates away from the lower region (150) and thus a fast It enables cooling to occur. The refrigerant in the vapor phase moves upwards. (SA) comes to the upper region (160). The volume of the upper region (160) is 30 times less than the volume of the lower region (150). 14 It is relatively smaller. Therefore, pressure imbalances within the system are triggered. Furthermore, the thermal energy absorbed from the lower region is transferred to the external environment in the upper region, forming steam. The coolant (SA) in the phase becomes liquid. The main flow part (140) contains numerous mini / micro It contains channels (180) of diameter. Liquid refrigerant (SA) passes through these channels. It moves towards the lower region (150) by the effect of capillarity. The movement is only due to capillary force 5 It is not achieved through its effect; it is also triggered as a result of the original design. Pressure imbalances also cause the liquid to move easily and quickly from the upper region (160) to the lower region (150). It helps to bring it about in some way. Thus, a new type of portable, thermally driven vehicle is created. By improving or accelerating the fluid circulation inside the passive cooler (100), high A cooling performance is achieved. 10 Another important point can be expressed as follows: Unlike conventional wick structures. as such, the main one used in a new type of portable passive cooler (100) driven by thermal energy. Due to the structure of the flow segment (140), the refrigerant in the vapor phase and the refrigerant in the liquid phase They move in opposite directions without touching each other in any way. This Therefore, no entrainment occurs between liquid and vapor flows; the liquid 15 The amount does not decrease, nor is the fluid flow obstructed due to the drag limit. Thermal energy. a new type of portable passive cooler (100) with drive, both its geometric structure and In terms of its working mechanism, it offers an advantage over the known state of the art. Mini / microchannels in a new type of portable passive cooler driven by thermal energy (100) (180) number, type of refrigerant (SA), type of materials forming the system, channel diameters 20 They may have different values. The stated changes are essentially related to the thermal energy driven by the invention. the working mechanism of a new type of portable passive cooler (100) or original It does not affect its quality.

(120), fill / drain port (121), fill / drain port plug (130), 5 Capillary effect with refrigerant (SA) and expanding cross-section main vapor channels (170). from the main flow part (140) which includes the mini / micro channels (180) The resulting thermal energy is driven by a new type of portable passive cooler (100), the feature of which is; Creating a capillary effect with expanding cross-section main vapor channels (170) mini / micro channels (180) together, the resulting steam is rapidly upwards 10 the interaction of liquid and vapor flows in opposite directions, which allows them to move away allowing it to happen without entering, limiting drag and friction. enabling the cooling process to continue without suffering losses, and main flow part (140) which improves cooling performance, Vapor bubbles or evaporation formed by the boiling of the refrigerant (SA) 15 The heat absorbed by the steam formed as a result from the surface to be cooled, expands... Due to its cross-sectional structure, it accelerates from the bottom surface and therefore from the bottom region (150). enabling upward removal and improving the cooling process expanding cross-section main steam channels (170), Unlike conventional wick structures, the liquid refrigerant (SA) is very 20 return to the lower region (150) by capillary action through the number of capillary channels mini / micro channels providing (180), Because the volume of the upper region (160) is less than that of the lower region (150). triggering pressure imbalances within the system and releasing them to the external environment. The refrigerant (SA) that condenses into the liquid phase due to thermal energy is subject to gravity and 25 In addition to capillary force, pressure imbalances triggered within the system This effect also ensures that the flow returns to the lower region, thus improving circulation and Therefore, geometric shapes allow for improved cooling performance. It includes configuration.
