Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of heat dissipation, in particular to a cooling plate. BACKGROUND

[0002] Metal die casting is a process that applies high pressure to molten metal through a mold to form a desired shape of casting, and the die casting mold needs to use a cooling plate to control the mold temperature, maintain the stability of the mold, prevent the mold from deforming and cracking, ensure the quality of the casting, and improve the production efficiency during the die casting process due to the continuous heating of high-temperature molten metal.

[0003] However, the traditional cooling plate usually adopts a single heat dissipation structure. Although this heat dissipation method can reduce the temperature of the equipment to a certain extent, the heat dissipation speed and efficiency still need to be improved. Especially in a high-temperature and high-load working environment, the single heat dissipation structure often cannot quickly dissipate the heat generated by the equipment, resulting in an increase in the temperature of the equipment and affecting the normal operation and service life of the equipment.

[0004] In addition, the installation and fixation of the water injection pipeline on the traditional cooling plate are also inconvenient. Many cooling plates require users to find a suitable way to connect the water injection pipeline with the cooling plate, which not only increases the operation difficulty of the users, but also may cause water leakage, poor heat dissipation effect, and other problems due to improper installation.

[0023] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] As Figures 1-4 shown, the utility model provides a kind of cooling plate, mainly used for the cooling plate on die casting die, to reach the effect of quick heat dissipation. The structure of the cooling plate mainly includes cooling plate body 1, is provided with the water tank 2 of downward recess in the top of the cooling plate body 1, the water tank 2 is mainly used to store normal temperature liquid water or low temperature liquid water, mainly through the liquid water absorption heat to achieve the effect of reduction. Heat conduction part 3 is arranged at one end of cooling plate body 1, heat conduction part 3 is mainly used to contact with die casting die and is used to absorb the heat of die casting die, the heat absorbed and heat conduction to one end of water tank 2, finally through the liquid in water tank 2 and heat neutralization cooling. It needs to be pointed out that, the liquid water will evaporate after being heated, therefore, it needs to constantly inject the liquid water for cooling into water tank 2.

[0025] Heat conduction part 3 for heat absorption and contact with die casting die is outwardly convex, to strengthen the stability after connection, and increase the area of heat conduction after contact, the side of heat conduction part 3 and die casting die contact is formed by two splicing surfaces. Two splicing surfaces are convex at connecting place, improve the stability after installation. When installing, first mounting hole 10 distributed on both sides of heat conduction part 3 is opened on cooling plate body 1, and is locked and fixed by screw etc. after installation and inserted into first mounting hole 10.

[0026] And the water tank 2 for storing liquid water, the structure of water tank 2 is formed by concentrically arranged first recess 201 and second recess 202, and second recess 202 is arranged at the bottom of first recess 201 to form a further downward recess structure. In order to make the injected liquid water flow smoothly into second recess 202, and prevent liquid water from splashing when injecting, the inner wall of first recess 201 is provided with an inclined structure, and the specific inclined structure is that the inner wall of first recess 201 gradually inclines from top to bottom, so that the opening of first recess 201 gradually decreases, at this time, the injected liquid water can flow into second recess 202 along the inclined inner wall of first recess 201.

[0027] When liquid water is injected into the water tank 2, it can be done by continuously injecting a certain amount of water. In order to more conveniently inject liquid water into the water tank 2, a pipe seat 4 is detachably mounted on the cooling plate body 1, and a plug hole 5 for inserting and fixing the water injection pipe is formed on the pipe seat 4. The user can insert the water injection pipe into the plug hole 5 to uniformly inject liquid water into the water tank 2. The pipe seat 4 is detachably connected with the cooling plate body 1, and a plurality of mounting grooves 11 for mounting the pipe seat 4 are formed on the cooling plate body 1 and surround the periphery of the water tank 2. The user can fix the water injection pipe at different angles according to the actual use, and use it flexibly. Correspondingly, the pipe seat 4 is provided with a mounting portion 12 inserted into the mounting groove 11.

[0028] At the bottom of the cooling plate body 1, a cavity 6 with one end open at the bottom is formed, which extends from the bottom of the cooling plate body 1 to the lower part of the water tank 2. When cooling, part of the heat is neutralized by the water in the water tank 2, and the other part is freely dissipated into the cavity 6. In order to increase the area of heat conduction and dissipation, four heat conduction bands 7 connected with the top of the cavity 6 are connected with the inner wall of the cavity 6. The four heat conduction bands 7 are arranged in parallel and the distribution direction is the same as the direction of heat conduction of the heat conduction portion 3 to the water tank 2. When the cooling plate body 1 conducts heat, the heat conduction area is increased by the heat conduction bands 7, and the heat at the top of the heat conduction bands 7 is absorbed by one end of the water tank 2, and at the same time, part of the heat is dissipated to speed up the dissipation speed. In order to speed up the heat dissipation speed in the cavity 6, the heat conduction bands 7 are provided with a plurality of inner heat dissipation holes 8 open on both sides, and the outer side of the cooling plate body 1 is provided with a plurality of outer heat dissipation holes 9 open to the inside of the cavity 6. The air flow speed is accelerated through the inner heat dissipation holes 8 and the outer heat dissipation holes 9.

[0029] In addition, four second mounting holes 14 for mounting and fixing are arranged on the cooling plate body 1, and the four second mounting holes 14 are arranged at the four corner positions of the cooling plate body 1. An arc-shaped groove 13 distributed around the periphery of the water tank 2 is arranged at the top of the cooling plate body 1, and two second mounting holes 14 are arranged at the two ends of the bottom of the arc-shaped groove 13.

[0030] Compared with the conventional technology, the cooling plate body 1 provided by the technical scheme not only directly cools by the water tank 2 arranged at the top, but also dissipates heat by the cavity 6 arranged at the bottom and the heat conduction bands 7 connected therewith, so that the cooling efficiency is significantly improved by adopting double heat dissipation paths. In addition, the cooling plate body 1 is provided with the pipe seat 4 for inserting and fixing the water injection pipe, so that liquid water can be conveniently and quickly injected into the water tank 2, and the operation is simplified.

[0031] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, no reference signs in the claims being regarded as limiting the claims concerned.
