Description

Technical Field

[0001] The invention relates to the technical field of contactor installation, in particular to an improved contactor heat dissipation structure. Background Art

[0002] A contactor is an automatic control device that uses electromagnetic, pneumatic or hydraulic operation principles to control the closing or opening of the internal contact system, thereby controlling the on and off of the circuit of the load electrical equipment. The installation structure satisfies the positioning and fixing of the contactor in a certain position. In order to ensure the heat dissipation performance of the contactor during use, the existing contactor installation structure uses a cold plate to install it, but the installation method between the contactor and the cold plate adopts a vertical installation method, resulting in a small contact surface between the two, affecting the actual heat dissipation effect. Therefore, it is necessary to provide a contactor installation structure that can solve the above technical drawbacks to improve the use effect. Summary of the invention

[0003] The object of the present invention is to provide an improved contactor heat dissipation structure to solve the problem raised in the above background technology that the existing contactor installation structure uses a cold plate to install the contactor in order to ensure the heat dissipation performance of the contactor during use, but the installation method between the contactor and the cold plate adopts a vertical installation method, resulting in a small contact surface between the two, which affects the actual heat dissipation effect.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is an improved contactor heat dissipation structure, comprising: An action module, the action module comprising a contactor housing 1, a contactor housing 2 and a contactor housing 3 arranged in sequence; An installation module includes a cold plate, a contactor spring sheet 1 and a contactor spring sheet 2, wherein the contactor spring sheet 1 and the contactor spring sheet 2 are respectively fixed on one side and the other side of the contactor housing 2, and one side of the contactor spring sheet 1 and the contactor spring sheet 2 are both threadedly provided with an adapter plate, and the bottom end of the adapter plate is fitted with the end portion of one side of the upper end of the cold plate and threadedly fixed.

[0005] Furthermore, a heat-conducting insulating gasket is provided in the gap between the contactor spring leaf 1, the contactor spring leaf 2 and the adapter plate.

[0006] Furthermore, the mounting module also includes a mounting plate, which is symmetrically fixed to the lower parts of three sides of the contactor housing, and the lower end of the mounting plate is attached to the two sides of the middle part of the upper end of the cold plate and is threadedly fixed.

[0007] Furthermore, the cooling liquid is injected into the inner cavity of the cold plate, and a delivery pipe is penetrated through the upper part of one side of the cold plate, and a plug is provided on the inner wall thread of the delivery pipe.

[0008] Furthermore, it also includes an auxiliary heat dissipation module, which includes an inflatable pad 1, an inflatable pad 2 and an air pipe. The inflatable pad 1 expands and fits the lower part of the inner wall of the cold plate, and the inflatable pad 2 is arranged at the upper end of the inflatable pad 1. One end of the air pipe passes through the inflatable pad 1 and extends into the inflatable pad 2, and the other end extends out of the cold plate and is connected to the output end of the air supply pump.

[0009] Furthermore, the auxiliary heat dissipation module also includes a threaded tube and a threaded ring. The threaded tube passes through the lower part of the other side of the cold plate, and the threaded tube is threadedly connected to one side of the outer surface of the gas pipe. The threaded ring passes through one side of the upper end of the cold plate, and a water immersion sensor is provided on the inner thread of the threaded ring, which extends into the cavity.

[0010] The present invention has the following beneficial effects: The present invention changes the original vertical installation mode between the contactor and the cold plate to a horizontal installation mode between the contactor and the cold plate, thereby improving the heat dissipation effect by increasing the contact surface, and after the contactor is placed horizontally, its height is reduced, which is helpful for subsequent inspection and maintenance.

[0011] Based on the above beneficial effects, when using the coolant inside the cold plate for heat dissipation, the amount of coolant used will gradually decrease, and it will no longer contact the top of the cold plate, resulting in the heat dissipation effect being affected. The expanded inflatable cushion can be used to move the coolant received by the upper end upward to always fit the upper end of the cold plate, thereby ensuring a good heat dissipation effect, improving applicability, and meeting needs.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0017] See also Figure 1-3 As shown, the present invention is an improved contactor heat dissipation structure, comprising: The action module includes a contactor housing 1 21, a contactor housing 22 and a contactor housing 3 23 which are arranged in sequence.

[0018] The mounting module includes a cold plate 11, a contactor spring 12 and a contactor spring 2 13. The contactor spring 12 and the contactor spring 2 13 are respectively fixed on one side and the other side of the contactor housing 22, and one side of the contactor spring 12 and the contactor spring 2 13 are both threadedly provided with an adapter plate 14. The bottom end of the adapter plate 14 is fitted with the end of one side of the upper end of the cold plate 11 and is threadedly fixed; The cold plate 11 provides an installation environment and cooperates with the following coolant 111 for heat dissipation of the contactor. The contactor spring 1 12 and the contactor spring 2 13 conduct the heat to the adapter plate 14 , and then conduct the heat to the cold plate 11 through the adapter plate 14 .

[0019] A heat-conducting insulating gasket 15 is provided in the gap between the contactor spring 12, the contactor spring 2 13 and the adapter plate 14; The heat-conducting insulating gasket 15 can ensure the tight connection between the contactor spring piece 12 and the contactor spring piece 2 13 while providing heat-conducting insulation.

[0020] The mounting module also includes a mounting plate 16, which is symmetrically fixed to the lower parts of both sides of the contactor housing 3 23, and the lower end of the mounting plate 16 is attached to both sides of the middle part of the upper end of the cold plate 11 and is screwed; The mounting plate 16 performs secondary fixing of the contactor and the cold plate 11 .

[0021] The cooling liquid 111 is injected into the inner cavity of the cold plate 11, and a delivery pipe 112 is penetrated through the upper part of one side of the cold plate 11, and a plug 113 is provided on the inner wall thread of the delivery pipe 112; The delivery pipe 112 is used to supplement the cooling liquid 111 in the inner cavity of the cold plate 11 , and the plug 113 is used to seal the delivery pipe 112 to prevent the cooling liquid 111 from leaking.

[0022] Working principle: Place the contactor horizontally, and use bolts to thread the contactor spring leaf 12, the contactor spring leaf 2 13 and the adapter plate 14 in advance. Before connecting the contactor spring leaf 12, the contactor spring leaf 2 13 and the adapter plate 14, it is necessary to insert the thermally conductive insulating gasket 15 into the gap of the docking position, and then use bolts to thread the adapter plate 14 and the cold plate 11, and then use bolts to fix the contactor and the cold plate 11 for a second time through the mounting plate 16. In actual use, the contactor spring leaf 12 and the contactor spring leaf 2 13 transfer heat to the adapter plate 14, and then transfer the heat to the cold plate 11 through the adapter plate 14, and the heat is dissipated by the coolant 111.

[0023] This solution improves the heat dissipation effect by increasing the contact surface, and after the contactor is placed horizontally, its height is reduced, which is helpful for subsequent inspection and maintenance.

[0024] See also Figure 1-3 As shown, this embodiment is based on the above embodiment and further includes an auxiliary heat dissipation module, the auxiliary heat dissipation module includes an inflatable pad 1 31, an inflatable pad 2 34 and an air pipe 33, the inflatable pad 1 31 expands and fits the lower part of the inner wall of the cold plate 11, and the inflatable pad 2 34 is arranged at the upper end of the inflatable pad 1 31, one end of the air pipe 33 passes through the inflatable pad 1 31 and extends into the inflatable pad 2 34, and the other end extends out of the cold plate 11 and is connected to the output end of the air supply pump; The inflatable pad 1 31 supports the inflatable pad 2 34 and performs edge sealing on the lower end of the inner wall of the cavity. After the inflatable pad 2 34 expands, the coolant 111 contacts the top surface of the cavity of the cold plate 11 to improve the heat dissipation effect. The air pipe 33 supplies air to the inside of the inflatable pad 2 34 .

[0025] The auxiliary heat dissipation module also includes a threaded tube 32 and a threaded ring 35. The threaded tube 32 passes through the lower part of the other side of the cold plate 11, and the threaded tube 32 is threadedly connected to one side of the outer surface of the gas delivery pipe 33. The threaded ring 35 passes through one side of the upper end of the cold plate 11, and the inner thread of the threaded ring 35 is provided with a water immersion sensor 36, which extends into the cavity. The threaded tube 32 limits the air delivery pipe 33 and ensures the connection sealing. The threaded ring 35 limits the connection of the water immersion sensor 36. The water immersion sensor 36 can be used to monitor whether the coolant 111 is on the top surface of the cavity.

[0026] Working principle: In the above-mentioned heat dissipation using the coolant 111, when the controlled water immersion sensor 36 detects that the coolant 111 is not on the top surface of the cavity, the principle is that under normal conditions, the two-pole probe is insulated by air. When the probe contacts water, due to the conductivity of water, a conductive state is formed between the two poles. After the sensor detects this change, it will output a dry contact signal or a digital signal (depending on the specific model and design), thereby triggering an alarm or other control action. At this time, a controlled external air supply pump is used to supply air to the inside of the inflatable cushion 2 34 through the air pipe 33 to expand it, so as to raise the coolant 111 and re-contact the top surface of the cavity of the cold plate 11.

[0027] This solution can always make the coolant 111 adhere to the inner upper end of the cold plate 11, ensure good heat dissipation effect, improve applicability, and meet the needs.
