Detailed Description
The invention is further illustrated by the following examples and figures of the specification.
Example 1
Industrial production environments are complex, thermoelectric modules cannot be exposed in a production line for long periods of time, and the modules are not small enough to produce large temperature gradients for industrial thermoelectric conversion. Based on the above factors, the following embodiments of the present invention provide an industrial integrated thermoelectric power generation device, which can not only improve the power generation performance of the thermoelectric module under operating conditions, but also maintain the efficient operation of the module for a long time.
The overall structure schematic diagram and the explosion diagram of an industrial integrated thermoelectric power generation device are shown in figure 1. Which comprises the following steps: baffle a, thermoelectric module b, cooling substrate c and water-cooling board d. The industrial field production environment is complicated, and the over-size of the thermoelectric power generation device structure is not beneficial to field installation and debugging, so the cooling substrate in the industrial integrated thermoelectric power generation device is provided with fixing grooves, the arrangement of the fixing grooves adopts a 6 x 6 structure, and at most 36 thermoelectric modules b can be installed inside the cooling substrate. Generally, the temperature range of an industrial heat source is wide, and the thermoelectric module b cannot be directly installed on the surfaces of some high-temperature heat sources and can only perform waste heat power generation in a mode of absorbing radiant heat. For the above reasons, the industrial integrated thermoelectric power generation device of the present invention is provided with the baffle a.
The structure of a baffle plate a used by the industrial integrated thermoelectric power generation device is shown as figure 2. In order to enable the heat absorption performance of the hot end of the thermoelectric module b not to be influenced, the baffle plate a adopts a barrier type structure and comprises the following components: a gear lever a-2, a main fixed column a-3 and an auxiliary fixed column a-4; the barrier structure comprises a plurality of barrier rods a-2, a plurality of main fixing columns a-3, a plurality of auxiliary fixing columns a-4 and a plurality of barrier rods a-3, wherein the barrier rods a-2 are uniformly distributed and are parallel to each other to form a barrier structure, gaps among the plurality of barrier rods are intervals a-1 between adjacent barrier rods, the main fixing columns a-3 are parallel to the barrier rods a-2 and are arranged in the centers of the barrier rods a, and the plurality of barrier rods are fixed; in order to fix each thermoelectric module b by the baffle plate a, the distance a-1 between the adjacent baffle plates is required to be smaller than the length and width of the thermoelectric module b, and the difference between the two is not more than 1 mm. When the non-contact working mode is adopted, the positions of all elements in the thermoelectric power generation device can be deviated, so that the main fixing post a-3 and the auxiliary fixing post a-4 are arranged at the center of the baffle plate a. The main fixing column a-3 is in direct contact with the edge of the thermoelectric module b, so that the stress is more uniform, and the baffle plate a can not be transversely deviated. The auxiliary fixing posts a-4 are disposed in the lateral spaces of the thermoelectric modules b so that the baffles a do not longitudinally deviate.
The structure of a thermoelectric module b used in an industrial integrated thermoelectric power generation device according to the present invention is as shown in fig. 3 (a). The thermoelectric module b used in the invention is a commercial module, the specific model is SP1848, and the thermoelectric module b comprises the following components: the device comprises an aluminum oxide insulating plate b-1, a copper conducting strip b-2, a P-type thermoelectric arm b-3, an N-type thermoelectric arm b-4 and a sealing layer b-5. The P-type thermoelectric arms b-3 and the N-type thermoelectric arms b-4 are alternately arranged, wherein one end of the P-type thermoelectric arm b-3 is connected with one end of the N-type thermoelectric arm b-4 adjacent to one side of the P-type thermoelectric arm b-3 through a copper conducting strip b-2, the other end of the P-type thermoelectric arm b-3 is connected with one end of the other N-type thermoelectric arm b-4 adjacent to the other side of the P-type thermoelectric arm b-3 through another copper conducting strip b-2, an aluminum oxide insulating plate b-1 at the upper end and an aluminum oxide insulating plate b-1 at the lower end are arranged, and the copper conducting strip b-2, the P-type thermoelectric arms b-3 and the N-type thermoelectric arms b-4 are all wrapped in the copper conducting strips; the specific connection mode is shown in FIG. 3 (b);
the P-type thermoelectric arm b-3 and the N-type thermoelectric arm b-4 are made of bismuth telluride, and are common thermoelectric materials. Since metal dust may occur in an industrial production environment, causing short-circuiting or damage to the thermoelectric module b, it is necessary to isolate the module from the environment. In fig. 3, b-5 is a sealing layer of the thermoelectric module b, and the sealing layer b-5 is made of a vulcanized silicone rubber material which can bear a high temperature of 800 ℃ at most and can cope with various high temperature environments.
The structure of a cooling substrate c used in an industrial integrated thermoelectric power generation device of the present invention is as shown in fig. 4(a) to 4 (c). The cooling substrate c comprises the following components: a fixed groove c-1, a lead through hole c-2, a hot end boss c-3, a cold end boss c-4 and a lead groove c-5. Wherein, the hot end of the cooling substrate c is provided with 36 fixed grooves c-1 in total, and a 6 multiplied by 6 arrangement structure is adopted. The fixing groove c-1 is used for fixing the position of the thermoelectric module b to prevent the position of the thermoelectric module from shifting during use. Since the hot end of the cooling substrate c and the cold end of the thermoelectric module b are rough surfaces, larger thermal contact resistance exists on the contact surfaces of the cooling substrate c and the thermoelectric module b. In order to reduce the adverse effect caused by the contact thermal resistance, the contact surface of the thermoelectric module b and the cooling substrate c needs to be uniformly coated with heat-conducting silicone grease. Since the high temperature limit of the thermoelectric module b is higher than that of the connection wire, it is necessary to control the surface temperature of the connection wire to maintain the stability of use. And one end of the fixed groove c-1 of the cooling substrate c is provided with a lead through hole c-2, the lead through hole c-2 can directly transfer a connecting lead from the hot end of the cooling substrate c to the cold end of the cooling substrate c, the connecting lead is arranged on the lead groove, and the temperature is controlled through the water cooling plate d. And the cold end of the cooling substrate c is provided with a wire groove c-5 for fixing the position of the connecting wire, so that the connecting wire is in direct contact with the water cooling plate d and can be in a low-temperature state for a long time. And the two ends of the thermoelectric module b are made of alumina ceramic materials, so that the brittleness is high, and when the local pressure on the end face of the thermoelectric module b is too high, the damage phenomenon can occur. And hot end bosses c-3 are arranged at four corners corresponding to the cooling substrate c and used for reducing pressure generated by the baffle a on the hot end of the thermoelectric module b, and the horizontal height of the hot end bosses c-3 is 0.5mm lower than that of the thermoelectric module b, so that the tightness of the baffle a is prevented from being influenced. And the cooling substrate c is provided with a cold end boss c-4 for improving the cold end temperature control capability of the thermoelectric module b and keeping the cold end temperature of the module uniform. The cold end boss c-4 of the cooling substrate c corresponds to the cold end of the thermoelectric module b, and the design can reduce the cooling efficiency of other areas of the cooling substrate c, so that the water cooling plate d only keeps efficient cooling on the thermoelectric module b.
The structure of the water cooling plate d adopted by the industrial integrated thermoelectric power generation device is shown in figure 5. The inside of the water cooling plate d is provided with 12 cooling water flow channels, and the number of the cooling water flow channels at the cold end of each thermoelectric module b is kept at 2. The cooling water flow channel and the cold end boss c-4 in the cooling substrate c are kept at the same position, so that the cooling efficiency of the water cooling plate d on the thermoelectric module b is more sufficient. The water inlet/outlet d-1 of the water cooling plate d is arranged on the same side, so that the arrangement of cooling water pipes in the use process is facilitated. The industrial integrated thermoelectric power generation device greatly improves the industrial applicability of the thermoelectric module b by configuring various auxiliary elements for the thermoelectric module b, and also provides an effective solution for industrial thermoelectric conversion technology.
