The cold conduction formula is Q ═ delta T/R_TWherein Q, Δ T, R_TThe refrigeration power, the refrigeration temperature difference and the refrigeration capacity conduction thermal resistance are respectively. From this equation, the conduction thermal resistance R_TThe smaller the conduction, the greater the conduction of cold. Due to conductive thermal resistanceWherein L, lambda and S are respectively the cold transmission distance, the heat conductivity coefficient and the conduction sectional area. According to the conductive thermal resistance R_TCalculation formula, reduction of conduction thermal resistance R_TThe technical scheme of (1) is to reduce the cold quantity conduction distance L. In addition, according to a heat exchange calculation formula Q ═ hS Δ T, wherein h, S, Δ T are surface heat exchange coefficient, heat exchange area and temperature difference respectively, and the formula can be known from this, and the increase heat exchange area can then improve the heat exchange quantity, and then realize the promotion of heat exchange efficiency. The method is obtained by analyzing the theory, improves the ice making efficiency in the ice making process, shortens the technical route of the ice making time, and is realized by increasing the exchange area between the groove cold and the water in the groove, reducing the cold conduction distance and the like.

The first embodiment is as follows:

referring to fig. 1 and 2, an ice making box includes an ice making box body 1, a groove 2 is formed on the surface of the ice making box body 1, the groove 2 is used for containing water for making ice cubes, a protrusion 3 is arranged at the bottom of the groove 2, the protrusion 3 and the ice making box body 1 are integrally formed, the bottom surface of the ice box is a plane for receiving cold energy required by ice making, the wall surface of the groove 2 and the surface of the protrusion 3 are joined with water, so that the cold energy conduction from the ice making box to the water is realized, the water cooling capacity conduction surface in the groove 2 is provided with the peripheral surface of the protrusion 3 except the inner wall surface of the groove 2, and the heat exchange area is increased. Meanwhile, the cold energy is changed from the pure one-way conduction from the wall surface of the groove 2 to the inside of the water into the three-dimensional cold energy conduction from the wall surface of the groove 2 and the wall surface of the bulge part 3 to the water in the groove 2 in the same direction, so that the groove 2 forms a three-dimensional cold transmission structure from inside to outside, the cold energy transmission distance is greatly reduced, the cold energy transmission thermal resistance is reduced, and the ice making of the water in the groove 2 from inside to outside is realized. In addition, the protruding part 3 not only reduces the cold transmission distance, but also increases the heat exchange area, enhances the cold exchange capacity between the surface of the ice making box and water, accelerates the ice making efficiency, ensures that ice cubes can be formed from inside to outside, and forms ice cubes meeting the requirements.

Referring to fig. 3, an arrow indicates a conduction path of cold energy of a groove of an ice-making box in the prior art, after the cold energy is conducted from the bottom of the ice-making box to an ice-making box body 1 made of a metal material, the cold energy is conducted to water in the groove 2 from the inner wall surface of the groove 2, the conduction distance of the cold energy is from the inner wall surface of the periphery to the center of the groove 2, and the cold energy is conducted to the water through the wall surface in the whole ice-making process, so that the water in the groove is cooled and. With the gradual reduction of the water temperature, the ice is frozen on the inner wall surface, and then the ice is gradually frozen layer by layer on the basis until reaching the center of the groove 2, thereby completing the whole ice making process. As the thermal conductivity coefficient of the ice is about 2.22W/mk, compared with a metal conductor, the thermal conductivity coefficient is small, the thermal conductivity is poor, namely, the cold quantity conduction thermal resistance is large, the cold quantity penetrates through the frozen ice to be condensed layer by layer in the ice making process, the cold quantity conduction thermal resistance is gradually increased along with the increase of the condensation thickness of the ice layer by layer relative to the wall surface of the groove 2, the condensation time of each layer of ice is gradually prolonged, and particularly, the time for the water in the center of the ice block to condense into the ice is very long, namely, the time for the water in the center of.

Referring to fig. 4, arrows show the conduction path of the cooling capacity of the groove of the ice-making housing of the small ice-making machine, increasing the wall surface area of the heat exchange between the cooling capacity and the water, assuming that the inner wall area of the groove 2 in fig. 4 is S₁The surface area of the projection 3 is S₂The area of the wall surface of the bottom surface covered by the projection 3 is S₃The increased water exchange wall surface area is S by providing the convex portion 3₂-S₃According to the formula of heat exchangeCan be used forCalculated, the temperature difference between the heat exchange surface and the water corresponding to the graph of 3 and the graph of 4 is respectivelyAndtherefore, for the same cooling capacity Q and surface heat transfer coefficient h, due to Delta T₂＜ΔT₁The temperature difference between water and cold heat exchange surfaces in the ice making box of the small ice maker is smaller than the corresponding parameter value of the prior figure 3, namely the heat exchange effect of the figure 4 is obviously better than that of the figure 3, the improvement characteristic is related to the increased area of the surface of the convex part 3, because the convex part 3 is added, the cold conduction of the figure 4 is changed into the three-dimensional conduction of the wall surface of the figure 4 and the convex part to the center of the groove 2 through the one-way conduction of the wall surfaces at the periphery of the figure 3 to the center of the groove 2, the cold transmission distance of the figure 3 is obviously longer than that of the figure 4 by taking a central line as a reference, and according to the theory, the cold conduction thermal resistance from the wall surface to the central line corresponding to the figure 3 is obviously higher than that of the figure 4.
