Description

Technical Field

[0001] This utility model relates to the field of welding machine cooling technology, specifically a cooling mechanism for welding machines. Background Technology

[0002] An electric welding machine uses the high-temperature electric arc generated when the positive and negative electrodes are momentarily short-circuited to melt the solder on the welding rod and the material being welded, thus bonding the objects together. Its structure is very simple; it's essentially a high-power transformer. Electric welding machines are generally classified into two types based on the type of output power: AC and DC. They utilize the principle of inductance; the inductance generates a huge voltage change when the circuit is switched on and off. The high-voltage arc generated when the positive and negative electrodes are momentarily short-circuited melts the solder on the welding rod, achieving atomic bonding.

[0003] Currently used welding machines are equipped with built-in cooling fans that run simultaneously with the machine to cool internal components. However, the heat emitted is exhausted through the heat dissipation holes on the welding machine housing and accumulates around the equipment, causing the local ambient temperature to rise. This turns the air source drawn in by the cooling fan into high-temperature gas, severely weakening its cooling effect and creating a negative cycle. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A cooling mechanism for an electric welding machine includes an air-cooling mechanism, a heat collection mechanism, and a cooling mechanism. The air-cooling mechanism includes a welding machine body, a filter screen embedded in the top of the welding machine body, and a fan suspended above the filter screen. The heat collection mechanism includes multiple return air ducts connected to the welding machine body and two air guide hoods connected to both ends of the return air ducts. The cooling mechanism includes an aerogel felt wrapped around the outside of the return air ducts, multiple cooling plates connected to the outer wall of the aerogel felt, and an insulation sleeve fitted over the outside of the aerogel felt. The inner wall of the insulation sleeve is fixedly connected to the body of the return air duct.

[0007] By adopting the above technical solution, when the fan cools the inside of the welding machine, the heat dissipation air mixes with the temperature inside the welding machine to form hot air, which flows through the return air duct. Then, multiple cooling plates work together to reduce the temperature of the aerogel felt. The low-temperature aerogel felt cools the hot air flowing through the duct by exchanging heat with the wall of the return air duct. The cooled airflow provides a sufficient source of cold air for the fan, thereby continuously and effectively maintaining the cooling effect on the welding machine body.

[0008] In a preferred embodiment, the present invention can be further configured such that: a mounting assembly is provided on the return air duct, the mounting assembly includes a support kit fixed to the inside of the return air duct, a horizontal shaft connecting the fan and the support kit, and the bottom of the support kit is fitted to the top of the insulation sleeve.

[0009] In a preferred embodiment, the present invention can be further configured such that: multiple vertical blocks are fixedly connected to the bottom of the welding machine body, and the multiple vertical blocks are arranged in a matrix.

[0010] In a preferred embodiment, this utility model can be further configured as follows: multiple return air ducts are arranged in pairs, forming two groups, with the two groups of return air ducts located on both sides of the welding machine body respectively. The top of the air guide shroud connected to the bottom of the return air duct is fixedly connected to the bottom of the welding machine body, and the air guide shroud connected to the top of the return air duct is suspended above the fan.

[0011] In a preferred embodiment, the present invention can be further configured such that: multiple cooling sheets on the aerogel felt are equally spaced and arranged in four columns, with the four columns of cooling sheets arranged in a ring.

[0012] In a preferred embodiment, this invention can be further configured such that multiple cooling elements are connected in series, and the fan and cooling elements are electrically connected to the welding machine body.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, when the fan cools the inside of the welding machine, the heat dissipation air mixes with the temperature inside the welding machine to form hot air, which flows through the return air duct. Then, multiple cooling plates work together to reduce the temperature of the aerogel felt. The low-temperature aerogel felt cools the hot air flowing through the duct by exchanging heat with the wall of the return air duct. The cooled airflow provides a sufficient source of cold air for the fan, thereby continuously and effectively maintaining the cooling effect on the welding machine body.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0028] The following describes, with reference to the accompanying drawings, some embodiments of a cooling mechanism for an electric welding machine. Example

[0029] Combination Figure 1-4 As shown, the present invention provides a cooling mechanism for a welding machine, including an air-cooling mechanism 100, a heat collection mechanism 200 and a cooling mechanism 300. The air-cooling mechanism 100 includes a welding machine body 110, a filter screen 120 embedded in the top of the welding machine body 110, and a fan 130 suspended in the top of the filter screen 120.

[0030] The heat collection mechanism 200 includes a plurality of return air pipes 210 connected to the welding machine body 110 and two air guide covers 220 respectively connected to both ends of the return air pipes 210.

[0031] The cooling mechanism 300 includes an aerogel felt 310 wrapped around the outside of the return air duct 210, a plurality of cooling plates 320 connected to the outer wall of the aerogel felt 310, and an insulation sleeve 330 fitted around the outside of the aerogel felt 310. The inner wall of the insulation sleeve 330 is fixedly connected to the body of the return air duct 210.

[0032] Furthermore, multiple return air ducts 210 are arranged in pairs, forming two groups. The two groups of return air ducts 210 are located on both sides of the welding machine body 110. The top of the air guide hood 220 connected to the bottom of the return air duct 210 is fixed to the bottom of the welding machine body 110. The air guide hood 220 connected to the top of the return air duct 210 is suspended above the fan 130. The layout design of the return air ducts 210 can evenly receive the hot air flowing out of the welding machine body 110, and at the same time, it can guide the cooled hot air in the return air ducts 210 to the top of the fan 130, providing the fan 130 with a low-temperature air source, ensuring the cooling effect on the welding machine body 110.

[0033] Furthermore, the multiple cooling pads 320 on the aerogel felt 310 are arranged in four rows at equal intervals, with the four rows of cooling pads 320 arranged in a ring. The layout design of the cooling pads 320 can uniformly cool the wall of the return air duct 210 and accelerate the cooling speed of the hot air inside the return air duct 210.

[0034] Furthermore, multiple cooling elements 320 are connected in series, and the fan 130 and the cooling elements 320 are electrically connected to the welding machine body 110. This structural design makes the device easier to control. Example

[0035] Combination Figure 1 and Figure 3 As shown, based on Embodiment 1, the return air duct 210 is provided with a mounting assembly 400. The mounting assembly 400 includes a support kit 410 fixed to the inside of the return air duct 210 and a horizontal shaft 420 connecting the fan 130 and the support kit 410. The bottom of the support kit 410 fits against the top of the insulation sleeve 330. The support kit 410 and the horizontal shaft 420 cooperate to firmly support the fan 130. Example

[0036] Combination Figure 1 As shown, in the above embodiment, the bottom of the welding machine body 110 is fixed with a plurality of upright blocks 500, which are arranged in a matrix. The upright blocks 500 enable the welding machine body 110 to stand firmly on the plane.

[0037] The working principle and usage process of this utility model are as follows: When the welding machine body 110 is started, the fan 130 and multiple cooling plates 320 are turned on simultaneously. The airflow generated by the fan 130 passes through the filter screen 120 to cool the inside of the welding machine body 110. The heat generated inside enters the air guide shroud 220 located at the bottom of the welding machine body 110 with the airflow, and then the hot air flows to the top of the fan 130 through the return air duct 210.

[0038] During this loop:

[0039] Cooling stage: Multiple cooling elements 320 work together to reduce the temperature of the aerogel felt 310;

[0040] Heat exchange stage: The low-temperature aerogel felt 310 cools the hot air flowing through the return air duct 210 by exchanging heat with the duct wall;

[0041] The cooled airflow provides a sufficient source of cold air for the fan 130, thereby continuously and effectively maintaining the cooling effect on the welding machine body 110.
