For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Reference below Figure 1-Figure 4 The intercooler pipe assembly 100 according to the embodiment of the utility model is described. The intercooler pipe assembly 100 can utilize the thermoelectric effect of the temperature difference semiconductor 23 to form a temperature difference electromotive force, realize temperature difference power generation, improve the engine intake efficiency, reduce the load of the intercooler system, and has low cost and high integration.

[0032] like Figure 1-Figure 4 As shown, the intercooler pipe assembly 100 according to the embodiment of the utility model includes: a first pipe body 1 and a second pipe body 2.

[0033] An inlet flow channel 11 and an outlet flow channel 12 are formed in the first tube body 1. The inlet flow channel 11 is suitable for communicating with the outlet of the supercharger, and the outlet flow channel 12 is suitable for communicating with the air inlet 13 of the engine.

[0034] Specifically, the first tube body 1 has a hollow structure inside to form an inlet flow channel 11 and an outlet flow channel 12, so that the gas flows in the first tube body 1. The supercharger can be an engine intake supercharger, which is an air compressor that increases the intake volume by compressing air so that the supercharged high-temperature and high-pressure gas enters the engine. However, the temperature of the supercharged gas is too high and needs to be cooled. Therefore, the intercooler pipe assembly 100 is connected between the supercharger and the air inlet 13 of the engine to cool the compressed gas. The port of the inlet flow channel 11 is connected to the outlet of the supercharger, and the port of the outlet flow channel 12 is connected to the air inlet 13 of the engine. That is, after the high-temperature gas compressed inside the supercharger flows out from the outlet of the supercharger, it flows into the first tube body 1 through the inlet flow channel 11 to cool it. The cooled gas flows out through the outlet flow channel 12 and flows into the engine from the air inlet 13 of the engine, thereby reducing the gas temperature at the end of the air inlet 13 of the engine, increasing the intake pressure, and increasing the effective power of the engine. In actual design, the supercharger may be a turbocharger.

[0035] Furthermore, the second tube body 2 is connected to the first tube body 1, and an airflow heat exchange channel 21 and a coolant heat exchange channel 22 are formed in the second tube body 2. The airflow heat exchange channel 21 is connected to the inlet channel 11 and the outlet channel 12 respectively, and a temperature difference semiconductor 23 is provided between the airflow heat exchange channel 21 and the coolant heat exchange channel 22.

[0036] Specifically, the first tube body 1 and the second tube body 2 are connected and communicated, so that the gas in the first tube body 1 and the gas in the second tube body 2 can circulate with each other, and an airflow heat exchange channel 21 and a coolant heat exchange channel 22 are formed inside the second tube body 2. The airflow heat exchange channel 21 is used to pass high-temperature gas, that is, the high-temperature gas circulates in the airflow heat exchange channel 21, and the coolant heat exchange channel 22 is used to pass coolant, that is, the coolant circulates in the coolant heat exchange channel 22, thereby cooling the high-temperature gas in the airflow heat exchange channel 21 to achieve a cooling effect on the high-temperature and high-pressure gas, so that the gas flowing out of the outlet air channel 12 is a low-temperature gas.

[0037] Among them, the thermoelectric semiconductor 23 can realize the conversion of thermal energy into electrical energy and has the first thermoelectric effect. The first thermoelectric effect refers to the thermoelectric phenomenon of the voltage difference between two substances caused by the temperature difference between two different electrical conductors or semiconductors. In other words, under the temperature gradient, the carriers in the conductor move from the hot end to the cold end and accumulate at the cold end, which can form a potential difference inside the material. At the same time, a reverse charge flow is generated under the action of the potential difference. When the charge flow of thermal motion reaches a dynamic equilibrium with the internal electric field, a stable thermoelectric electromotive force is formed at both ends of the semiconductor. The thermoelectric electromotive force of the semiconductor is large, and it can be used as a thermoelectric generator to realize thermoelectric power generation.

[0038] The thermoelectric semiconductor 23 is arranged between the airflow heat exchange channel 21 and the coolant heat exchange channel 22, that is, one side of the thermoelectric semiconductor 23 contacts the airflow heat exchange channel 21 to form a high temperature end, and the other side contacts the coolant heat exchange channel 22 to form a low temperature end, so that one side of the thermoelectric semiconductor 23 has a high temperature and the other side has a low temperature. A temperature gradient, that is, a temperature difference, can be formed between the two levels of the thermoelectric semiconductor 23, thereby forming a thermoelectric electromotive force, which can be further used as a thermoelectric generator for power generation. In other words, the waste heat of the engine can be used to generate electricity as reserve electric energy, reduce the fuel consumption of the engine, and improve the power generation efficiency of the engine. In actual design, the thermoelectric semiconductor 23 can be a bismuth telluride semiconductor, which has good electrical conductivity, and the thermoelectric effect of bismuth telluride can be used to form an electromotive force, thereby achieving the purpose of thermoelectric power generation.

[0039] And because the temperature difference semiconductor 23 is designed in the second tube body 2, that is, the limited space inside the second tube body 2 is utilized to realize temperature difference power generation, increase power generation, reduce engine fuel consumption, and have a high degree of integration. At the same time, the gas temperature of the outlet flow channel 12 of the first tube body 1 can be reduced, the load of the intercooler system can be reduced, the temperature of the intake gas of the engine can be cooled, and the engine intake efficiency can be improved. Moreover, the intercooler pipe assembly 100 of this embodiment does not require an overall upgrade of the material of the intercooler pipe, thereby reducing the design difficulty and cost.

[0040] According to the intercooler pipe assembly 100 of the embodiment of the utility model, a temperature difference semiconductor 23 is arranged between the air flow heat exchange channel 21 and the coolant heat exchange channel 22, so that a temperature gradient is formed at both ends of the temperature difference semiconductor 23, and a thermoelectric effect of the temperature difference semiconductor 23 is used to form a temperature difference electromotive force to achieve temperature difference power generation. At the same time, the coolant in the coolant heat exchange channel 22 can cool the high-temperature gas in the air flow heat exchange channel 21 and reduce the temperature of the gas flowing out of the outlet air channel 12, thereby achieving the cooling of the gas at the engine air intake 13 and improving the engine air intake efficiency. In addition, the intercooler pipe assembly 100 reduces the load of the intercooler system, has low cost and high integration.

[0041] In some embodiments, the second tube body 2 is sleeved outside the first tube body 1, that is, the radial dimension of the second tube body 2 is larger than the radial dimension of the first tube body 1, and the interior is hollow, so that the second tube body 2 can be sleeved outside the first tube body 1, and the airflow heat exchange channel 21, the temperature difference semiconductor 23 and the cooling liquid heat exchange channel 22 are spirally coiled and distributed in the second tube body 2.

[0042] Specifically, Figure 4As shown, the second tube body 2 is sleeved on the outer peripheral wall of the first tube body 1, the interior of the second tube body 2 is hollow, and the airflow heat exchange channel 21, the temperature difference semiconductor 23 and the cooling liquid heat exchange channel 22 are staggered and spirally coiled in the second tube body 2, and are wrapped around the first tube body 1. In other words, the airflow heat exchange channel 21, the temperature difference semiconductor 23 and the cooling liquid heat exchange channel 22 are all spiral structures and are axially distributed between the outer peripheral wall of the first tube body 1 and the interior of the second tube body 2, so that the airflow heat exchange channel 21, the temperature difference semiconductor 23 and the cooling liquid heat exchange channel 22 can fill the interior of the second tube body 2, making full use of the internal space of the second tube body 2 and improving the degree of integration.

[0043] Thus, by spirally winding the airflow heat exchange channel 21, the temperature difference semiconductor 23 and the cooling liquid heat exchange channel 22 in the second tube body 2, and extending axially from one end to the other end of the second tube body 2, an axially staggered temperature difference semiconductor 23 can be formed, which is evenly distributed in the second tube body 2, and the airflow heat exchange channel 21 and the cooling liquid heat exchange channel 22 are evenly distributed on both sides of the temperature difference semiconductor 23, so that a stable temperature difference can be formed at both ends of the temperature difference semiconductor 23, thereby forming a stable electromotive force, improving the power generation efficiency, and making full use of the limited space in the second tube body 2, greatly improving the degree of integration. For example, Figure 4 The thick arrow indicates the flow direction of the gas, and the thin arrow indicates the flow direction of the coolant. The high-temperature gas enters the air flow heat exchange channel 21 from the inlet flow channel 11, and the temperature is transferred to the hot end of the temperature difference semiconductor 23 through the air flow heat exchange channel 21. For example, the temperature can be maintained at around 200°C. The temperature of the cold end of the temperature difference semiconductor 23 can be maintained at around 90°C under the action of the coolant in the coolant heat exchange channel 22, so that a stable temperature difference of 110°C can be formed at both ends of the temperature difference semiconductor 23, thereby forming a stable electromotive force at both ends of the conductive electrodes of the temperature difference semiconductor 23.

[0044] At the same time, when the air flow heat exchange channel 21 extends from the inlet air flow channel 11 to the outlet air flow channel 12, under the action of the coolant in the coolant heat exchange channel 22 staggered between the air flow heat exchange channel 21, the temperature of the high-temperature gas in the air flow heat exchange channel 21 can be gradually reduced, and finally the cooled gas flows out from the outlet air flow channel 12 to achieve a cooling effect.

[0045] In addition, the second tube body 2 and the first tube body 1 can be separately arranged or integrally arranged. The separate arrangement allows the second tube body 2 to be disassembled relative to the first tube body 1, making installation and disassembly convenient, thereby facilitating the installation of components in the second tube body 2. It is flexible and convenient and can be flexibly designed according to actual needs.

[0046] In some embodiments, the intercooler pipe assembly 100 also includes a thermal insulation pad 24, which is used to preserve the temperature in the airflow heat exchange channel 21. The thermal insulation pad 24 is spirally coiled and distributed in the second tube body 2. The airflow heat exchange channel 21, the temperature difference semiconductor 23, the coolant heat exchange channel 22 and the thermal insulation pad 24 are distributed in sequence along the axial direction of the second tube body 2, that is, the thermal insulation pad 24 is arranged between the coolant heat exchange channel 22 and the airflow heat exchange channel 21, which can prevent heat exchange between the airflow heat exchange channel 21 and the coolant heat exchange channel 22, and can better preserve the temperature in the airflow heat exchange channel 21, so that the hot end of the temperature difference semiconductor 23 can maintain a stable high temperature, and the cold end can maintain a stable low temperature, so that a stable temperature difference is formed at both ends of the temperature difference semiconductor 23, forming a stable electromotive force, thereby improving the power generation efficiency and the reliability of thermoelectric power generation.

[0047] like Figure 4 As shown, the intercooler pipe assembly 100 also includes a thermal insulation pad 24. The thermal insulation pad 24, the coolant heat exchange channel 22, the temperature difference semiconductor 23 and the airflow heat exchange channel 21 are spirally coiled in sequence along the axial direction of the second tube body 2, so that the axially distributed airflow heat exchange channel 21 and the coolant heat exchange channel 22 are isolated by the thermal insulation pad 24 to prevent heat exchange. The coolant heat exchange channel 22 is adjacent to the temperature difference semiconductor 23, and the cold end of the temperature difference semiconductor 23 can be dissipated to form a stable low-temperature end. The airflow heat exchange channel 21 is adjacent to the temperature difference semiconductor 23, and the temperature of the hot end of the temperature difference semiconductor 23 is increased to form a stable high-temperature end, thereby forming a stable electromotive force.

[0048] Among them, it should be noted that the distribution form of the airflow heat exchange channel 21, the temperature difference semiconductor 23, the coolant heat exchange channel 22 and the thermal insulation pad 24 in the second tube body 2 is not limited to that described in this embodiment. They can also be directly installed in the second tube body 2 in a detachable separate structure, as long as the airflow heat exchange channel 21, the temperature difference semiconductor 23, the coolant heat exchange channel 22 and the thermal insulation pad 24 can be staggered and distributed in sequence to form a temperature difference electromotive force.

[0049] In some embodiments, the peripheral wall of the first tube body 1 is provided with an air inlet 13 and an air outlet 14 spaced apart along the axial direction, the air inlet 13 is connected between the inlet flow channel 11 and the air flow heat exchange flow channel 21, that is, the high-temperature gas can flow from the inlet flow channel 11 into the air flow heat exchange flow channel 21 through the air inlet 13, and the air outlet 14 is connected between the air flow heat exchange flow channel 21 and the outlet flow channel 12, that is, the low-temperature gas after cooling can flow from the air flow heat exchange flow channel 21 into the outlet flow channel 12 through the air outlet 14.

[0050] Specifically, Figure 4As shown, an air inlet 13 is provided on the peripheral wall of one end of the first tube body 1, and an air outlet 14 is provided on the peripheral wall of the other end of the first tube body 1, so that the air inlet 13 and the air outlet 14 are distributed on the peripheral wall of the first tube body 1 at intervals along the axial direction, and the air inlet 13 and the air outlet 14 are distributed at both ends of the axial direction of the second tube body 2. The first tube body 1 and the second tube body 2 can be connected through the air inlet 13 and the air outlet 14, so that the gas in the first tube body 1 and the gas in the second tube body 2 can be exchanged and circulated. In practice, after the high-temperature and high-pressure gas flowing out from the outlet end of the supercharger enters the inlet flow channel 11, it can flow into the air flow heat exchange flow channel 21 in the second tube body 2 through the air inlet 13, and is cooled by the coolant. The low-temperature gas after cooling can flow out from the air flow heat exchange flow channel 21 through the air outlet 14, enter the outlet flow channel 12 in the first tube body 1, and finally flow into the air inlet 13 of the engine from the outlet flow channel 12.

[0051] In some embodiments, the air inlet 13 and the air outlet 14 are located on both sides of the axis of the first tube body 1 .

[0052] Specifically, Figure 4 As shown in the upper and lower directions, the air inlet 13 is located on the upper side of the axis of the first tube body 1, and the air outlet 14 is located on the lower side of the axis of the first tube body 1, that is, the air inlet 13 and the air outlet 14 are respectively located on both sides of the axis of the first tube body 1, which is conducive to the inflow of high-temperature gas and the outflow of low-temperature gas.

[0053] In some embodiments, the inlet flow channel 11 and the outlet flow channel 12 are arranged opposite to each other along the axial direction of the first tube body 1 , and a partition baffle 15 is disposed in the first tube body 1 between the inlet flow channel 11 and the outlet flow channel 12 .

[0054] Specifically, Figure 4 As shown, the inlet flow channel 11 and the outlet flow channel 12 are arranged opposite to each other along the axial direction of the first tube body 1, so that the high-temperature gas flows into the inlet flow channel 11, and the low-temperature gas after cooling flows out from the outlet flow channel 12. Moreover, this structural design is simple and convenient, and the inlet flow channel 11 and the outlet flow channel 12 can be designed to be as large as possible to increase the gas flow rate and improve the efficiency. Among them, a partition baffle 15 is arranged between the inlet flow channel 11 and the outlet flow channel 12, and the inlet flow channel 11 and the outlet flow channel 12 can be separated by the partition baffle 15, so that the high-temperature gas enters the airflow heat exchange flow channel 21, and the high-temperature gas in the inlet flow channel 11 is prevented from flowing out from the outlet flow channel 12.

[0055] In some embodiments, a water inlet pipe 25 and a water outlet pipe 26 are connected to the peripheral wall of the second tube body 2 , and the water inlet pipe 25 and the water outlet pipe 26 are respectively located at two ends of the second tube body 2 .

[0056] Specifically, Figure 1 and Figure 2As shown, a water inlet pipe 25 and a water outlet pipe 26 are connected to the peripheral wall of the second tube body 2, and the water inlet pipe 25 and the water outlet pipe 26 are respectively located at the two ends of the second tube body 2 along the axial direction, and the water outlet pipe 26 can be connected between the cooling water system of the engine and the coolant heat exchange flow channel 22, that is, the coolant of the cooling water system can enter the coolant heat exchange flow channel 22 through the water inlet pipe 25, and then provide a stable low-temperature end for the temperature difference semiconductor 23. The coolant after heat exchange can flow out of the coolant heat exchange flow channel 22 through the water outlet pipe 26, further improving the stability of the low-temperature end of the temperature difference semiconductor 23.

[0057] In some embodiments, the water inlet pipe 25 and the water outlet pipe 26 are located on the same side of the outer peripheral wall of the second tube body 2 and are distributed in parallel and spaced apart.

[0058] Specifically, Figure 1-Figure 3 As shown, the water inlet pipe 25 and the water outlet pipe 26 are arranged on the same side of the outer peripheral wall of the second tube body 2, and are distributed in parallel at both ends of the second tube body 2 with a certain distance apart. In this way, the pipeline arrangement can be compact, and the installation and maintenance of the water inlet pipe 25 and the water outlet pipe 26 are convenient. It is also beneficial to connect the water inlet pipe 25 and the water outlet pipe 26 with the cooling water system. The cooling water system can be arranged on the same side of the water inlet pipe 25 and the water outlet pipe 26 to improve the degree of integration, thereby facilitating the circulation of the coolant and improving the heat exchange efficiency.

[0059] The utility model also proposes a temperature difference power generation system.

At the same time, the coolant in the coolant heat exchange flow channel 22 can cool the high-temperature gas in the air flow heat exchange flow channel 21, and reduce the temperature of the gas flowing out of the outlet flow channel 12, thereby achieving the cooling of the gas temperature of the engine air intake 13 and improving the engine intake efficiency. In addition, the intercooler pipe assembly 100 reduces the load of the intercooler system, has low cost and high integration.
