Abstract
The invention relates to a single-chip thermoelectric module testing device, which is particularly suitable for fixing and positioning and mounting a single-chip thermoelectric module. The problem of can accurately fix and occupation space is little, easily measure, install and tear the convenient requirement open is solved. The fixing device consists of two screws, a piece of flat steel, a radiator and a heat source generator, wherein the flat steel is matched with the screws to adjust the pressing degree, and the pressing force is determined according to the area and the height of the thermoelectric module. The screw pressure and the flat steel are matched to vertically bear force, the thermoelectric module is subjected to plane pressing, eccentric force is not generated, the flat steel pressing is suitable for accurate fixed installation of all regular plane modules, the thread scales are required to be thin, and the screw is locked as shown in fig. 4.
Description
Technical Field
The invention relates to a single-chip thermoelectric module testing device which is suitable for fixing a single-chip thermoelectric module, has larger area and larger stress, is not suitable for occasions when being fixed by a screw rod and is particularly suitable for occasions only subjected to pressing and positioning.
Background
The single-chip thermoelectric module testing device is used for pressing, positioning and connecting thermoelectric modules. The thermoelectric module can be positioned through the single-chip thermoelectric module testing device, the length and width fixing angle, the heat source and the heat dissipation end are seamlessly combined, the arrangement angle of the thermoelectric module can be adjusted, and the thermoelectric module is convenient to install and disassemble.
The single-chip thermoelectric module testing device is various in types, flat steel press fit connection is a common connection mode, for the thermoelectric blocks of a single PN joint, the thermoelectric modules with the same area and the smaller area are suitable for flat steel press fit connection, the connector structure is few, the close-fitting device uses thin teeth, and two ends of the close-fitting device are used for screwing arrow-shaped nuts and are connected.
For the installation test of cylindrical or square thermoelectric modules, the adopted connector is also a flat steel pressing device, and the connector can be made into a complex structure, can be effectively used for installation and fixation and can also be used for adjusting the angle and the pressing degree.
At present, mechanical armoring devices are adopted for large thermoelectric module systems or thermoelectric conversion modules, the armoring devices can ensure the stability of the whole system, but the armoring devices are fastened by large device nuts, and have the disadvantages of uneven stress, uneven heat dissipation, large occupied area and poor economic benefit.
Disclosure of Invention
The invention aims to provide a single-chip thermoelectric module testing device which can accurately position and press thermoelectric modules, has few devices, is easy to install and has a simple structure.
The invention discloses a single-chip thermoelectric module testing device which is mainly formed by pressing, connecting and assembling a heat source generator, a flat steel, a bolt fixer and a radiator, wherein the laminating degree of a thermoelectric module is pressed, two screw nuts are screwed on and press flat steel sheets, the laminating and the tight joint of the thermoelectric module and a heat conducting material are determined according to the area and the height of the thermoelectric module, and the laminating degree is reduced along with the increase of pressure.
The pressing surface of the single-chip thermoelectric module testing device is vertical to the pressure direction, no other acting force is generated on the thermoelectric module, and the requirements of the pressing force strength of the screws at the two sides on the thermoelectric module are not high.
The invention has the following effects: the fixing device has a good effect on fixing the thermoelectric module and requiring convenient installation and disassembly. The size of the fixing device can be increased with increasing pressure and increasing width of the flat steel, and the increased size of the fixing device can be larger.

Detailed Description
As shown in fig. 1: in the figure, 1 and 2 are respectively a heat source generator, a flat steel pressing sheet and a 3-radiator.
The arrow-shaped bolts on the two sides of the pressed flat steel are fixed by screws with the same pitch and diameter, the advancing distances of the two sides are equal, the heat source generator, the thermoelectric module and the radiator are connected in a pressed mode to be mutually attached and contacted, the surface of the heat source is a stress surface, and the pressing vertical force of the flat steel is determined according to the area and the height of the thermoelectric module. The larger the area is, the larger the bearing pressure is, and the larger the force is, the better the pressing effect is.
The matching of the flat steel and the screw: the flat steel is the acting force of the pressing stress surface in the horizontal direction, the screw rod is the person applying force by the device, the pressing degree of the thermoelectric module is effectively adjusted according to the thickness and the fineness of the tooth pitch on the screw rod, and the screw rods on the two sides move forward at equal intervals to press the flat steel for fixing the device. The pressfitting dynamics that thermoelectric module bore under the normal condition is according to the screw rod pressure of executing, and the flat steel carries the pressure of changeing, comes the fixed test power generation effect through the cooperation of thermoelectric module and heat conduction material, and the dynamics is too big can make thermoelectric module damaged by the crushing, generally measures the pressfitting degree according to the sieve chi and judges the pressure degree of executing. When the installation requirement is higher, the arrow-shaped nut is screwed up by using the left quarter turn and the right quarter turn respectively, and the adjustment operation is stable.
