Description

Technical Field

[0001] The present invention relates to the field of kitchen utensils, and particularly to an improved thawing plate. Background Art

[0002] Currently, thawing plates sold on the market for thawing frozen foods such as these mainly achieve the purpose of thawing food through the heat conduction effect of a heat pipe hidden in an aluminum plate. Since traditional heat pipes are relatively large in outer diameter and must be provided with structures such as capillary tissues and cannot reduce their pipe diameters, it is also difficult to make the overall thickness of the plate body thinner. In addition, ordinary aluminum plates are not well-designed and are only designed in a plate shape with the concept of covering the heat pipe. Therefore, not only is the thickness relatively thick, but the production is also more difficult due to the need to cover the heat pipe. If the heat pipe is clamped between plates, two sets of molds are also required for production due to lack of ingenious design, resulting in an increase in production costs or waste. In view of this, we propose an improved thawing plate to solve the above problems. Summary of the Invention

[0003] The purpose of the present invention is to propose an improved thawing plate with a light and thin design for the problems existing in the background art.

[0004] The technical solution of the present invention: An improved thawing plate includes a composite platform, handles provided on both sides of the composite platform, and a pulse heat exchanger. The composite platform includes two corresponding heat conduction plates that are stacked on top of each other; the pulse heat exchanger includes a first pulse heat pipe and a second pulse heat pipe provided between the heat conduction plates;

[0005] Both the first pulse heat pipe and the second pulse heat pipe are bent into a plurality of meandering segments and are stacked in a staggered manner with each other;

[0006] A liquid storage tank for storing ice water or hot water is provided inside the handle, and an interface for inserting the first pulse heat pipe and the second pulse heat pipe is provided on one side of the liquid storage tank.

[0007] Preferably, any one of the heat conduction plates has a fitting surface for stacking. A plurality of grooves recessed inward from the fitting surface and a plurality of ribs protruding outward from the fitting surface are provided on the fitting surface, and a groove formed on the fitting surface is recessed inward between adjacent grooves and ribs.

[0008] Preferably, when the two heat conduction plates are corresponding up and down, among the heat conduction plates located above, the grooves respectively correspond to the ribs of the heat conduction plates located below;

[0009] Among the heat conduction plates located below, the grooves respectively correspond to the ribs of the heat conduction plates located above.

[0010] Preferably, the fitting surface is formed by aluminum extrusion using the same set of molds.

[0011] Preferably, the handle is provided with an injection port for injecting ice water or hot water, and the injection port is blocked by a cap.

[0012] Preferably, after the first pulsating heat pipe and the second pulsating heat pipe pass through the connection interface and enter the liquid storage tank, the gaps between the first pulsating heat pipe, the second pulsating heat pipe and the connection interface are sealed by ultrasonic welding or further adding waterproof glue.

[0013] Preferably, the first pulsating heat pipe and the second pulsating heat pipe are connected by a connecting block, and a third pulsating heat pipe is connected along the width direction of the liquid storage tank through the connecting block.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] (1): Using a double-loop pulsating heat exchanger to replace the traditional heat pipe to achieve the effect of maximizing the contact area. In addition, the two ends of the heat pipe in a general thawing plate cannot be accelerated in cooling and heating by natural convection or other means. Therefore, in this design, water storage handles are added at both ends so that both ends of the pulsating heat exchanger can pass through the water storage handles and perform effective heat exchange to significantly improve the thawing or heating effect;

[0016] (2): Compared with using a heat pipe in a general thawing plate, a pulsating heat pipe can be bent freely in a limited space; a pulsating heat pipe eliminates the capillary structure, so the cost can be greatly reduced. Because the pulsating heat pipe can be bent freely in the plate to achieve the effect of maximizing the contact area, the efficiency is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0024] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Embodiment 1

[0026] As Figure 1 shown, an improved thawing plate proposed by the present invention includes a composite platform 1, handles 3 arranged on both sides of the composite platform 1, and a pulse heat exchanger 2. The composite platform 1 includes two corresponding heat conducting plates 10 stacked up and down; the pulse heat exchanger 2 includes a first pulse heat pipe 20 and a second pulse heat pipe 21 arranged between the heat conducting plates 10;

[0027] Both the first pulse heat pipe 20 and the second pulse heat pipe 21 are bent into a plurality of detour segments and are stacked in a staggered manner with each other; in this embodiment, both the first pulse heat pipe 20 and the second pulse heat pipe 21 can be bent into a plurality of detour segments with a curvature of 20 mm in diameter, that is, as Figure 1 shown, and are stacked in a staggered manner with each other to form a double-loop pulse heat exchanger;

[0028] In addition, the pulse heat exchanger refers to a pulse heat pipe, and a copper pipe with an outer diameter of about 3 mm and an inner diameter of about 2 mm can be used, which can achieve the design purpose of light and thin thickness;

[0029] Combined with Figure 5 shown, a liquid storage tank 30 for storing ice water or hot water is arranged in the handle 3, and an interface 31 for inserting the first pulse heat pipe 20 and the second pulse heat pipe 21 is arranged on one side of the liquid storage tank 30;

[0030] Referring to Figure 4 , it should be noted that the liquid storage tank 30 can be single and arranged on one side of the composite platform 1, or can be multiple and arranged on the opposite two sides of the composite platform 1 respectively; in this embodiment, multiple liquid storage tanks 30 are respectively arranged on the opposite two sides of the composite platform 1 as an example. At the same time, the pulse heat exchanger 2 extends out of the opposite two sides of the composite platform 1 and extends into the two liquid storage tanks 30 respectively.

[0031] As Figure 2 and Figure 3As shown, any heat conducting plate 10 has a fitting surface 100 for stacking. Multiple grooves 101 recessed inward from the fitting surface 100 and multiple ribs 102 protruding outward from the fitting surface 100 are provided on the fitting surface 100, and a groove 103 formed on the fitting surface 100 is recessed inward between adjacent grooves 101 and ribs 102.

[0032] After being stacked up and down, the pulse heat exchanger 2 can be clamped in the groove 103, and the two heat conducting plates 10 can be combined by additional components such as screws, so that the pulse heat exchanger 2 and the composite platform 1 are combined into one body.

[0033] When the two heat conducting plates 10 correspond to each other up and down, in the heat conducting plate 10 located above, its grooves 101 respectively correspond to the ribs 102 of the heat conducting plate 10 located below;

[0034] In the heat conducting plate 10 located below, its grooves 101 respectively correspond to the ribs 102 of the heat conducting plate 10 located above; the fitting surface 100 is formed by aluminum extrusion with the same set of molds.

[0035] In other words, the two heat conducting plates 10 can actually be formed by aluminum extrusion with the same set of molds, and only need to be stacked up and down to cooperate with each other and form a composite platform 1, which helps to reduce production costs and facilitate mass production.

[0036] A filling port 32 for injecting ice water or hot water is provided on the handle 3, and the filling port 32 is blocked by a cover 4.

[0037] After the first pulse heat pipe 20 and the second pulse heat pipe 21 pass through the interface 31 and enter the liquid storage tank 30, the gaps between the first pulse heat pipe 20, the second pulse heat pipe 21 and the interface 31 are sealed by ultrasonic welding or further adding waterproof glue. Of course, a sealing method that can achieve the same sealing effect can also be selected.

[0038] Based on the working principle of the first embodiment: Foods to be cooled or thawed and gently heated can be placed on the composite platform 1. Through the cold water or hot water injected into the liquid storage tank 30, and then through the heat exchange between the pulse heat exchanger 2 and the cold water or hot water injected into the liquid storage tank 30, the water temperature can be quickly transferred to the composite platform 1 to achieve the purpose of warming or thawing the food.

[0039] For example, when cold water is added, foods such as drinks can be cooled; when hot water is added, frozen foods can be thawed or moderately heated for slightly warm drinks. Since it is composed of a thinned composite platform 1 and a pulse heat exchanger 2 with a smaller diameter, not only is the overall thickness light and thin, but also the heat exchange effect can be quickly provided.

[0040] Embodiment 2

[0041] As shown in Figures 1-5 FIG. 5, an improved thawing plate proposed by the present invention includes a composite platform 1, handles 3 disposed on both sides of the composite platform 1, and a pulse heat exchanger 2. The composite platform 1 includes two corresponding heat conducting plates 10 that are stacked one above the other; the pulse heat exchanger 2 includes a first pulse heat pipe 20 and a second pulse heat pipe 21 disposed between the heat conducting plates 10;

[0042] Both the first pulse heat pipe 20 and the second pulse heat pipe 21 are bent into a plurality of meandering segments and are stacked in a staggered manner with each other;

[0043] A liquid storage tank 30 for storing ice water or hot water is disposed in the handle 3, and an interface 31 for inserting the first pulse heat pipe 20 and the second pulse heat pipe 21 is disposed on one side of the liquid storage tank 30.

[0044] Any one of the heat conducting plates 10 has a fitting surface 100 for stacking. A plurality of grooves 101 recessed inward from the fitting surface 100 and a plurality of ribs 102 protruding outward from the fitting surface 100 are disposed on the fitting surface 100, and a groove 103 formed on the fitting surface 100 is recessed inward between adjacent grooves 101 and ribs 102.

[0045] When the two heat conducting plates 10 are corresponding up and down, among the heat conducting plates 10 located above, the grooves 101 respectively correspond to the ribs 102 of the heat conducting plates 10 located below;

[0046] Among the heat conducting plates 10 located below, the grooves 101 respectively correspond to the ribs 102 of the heat conducting plates 10 located above.

[0047] The fitting surface 100 is formed by aluminum extrusion using the same set of molds.

[0048] A filling port 32 for injecting ice water or hot water is disposed on the handle 3, and the filling port 32 is blocked by a cover 4.

[0049] After the first pulse heat pipe 20 and the second pulse heat pipe 21 pass through the interface 31 and enter the liquid storage tank 30, the gaps between the first pulse heat pipe 20, the second pulse heat pipe 21 and the interface 31 are sealed by ultrasonic welding or further adding waterproof glue.

[0050] As shown in Figure 6 FIG. 6, in this embodiment, the first pulse heat pipe 20 and the second pulse heat pipe 21 are connected by a connecting block 22, and a third pulse heat pipe 220 is connected along the width direction of the liquid storage tank 30 to make the water temperature in the liquid storage tank more uniform.
