Description

Spacers and refrigeration equipment

technical field

The present invention relates to a spacer and a refrigeration device.

Background technique

In the refrigeration equipment as an independent equipment, the condenser of the refrigeration circuit is generally installed on the inner side of the outer wall of the refrigeration equipment. This structure has no pipes visible from the outside, yet ensures efficient heat exchange. If such refrigerating devices are arranged side by side or close to the wall, due to insufficient air circulation, the condenser installed on the inner side of the refrigerating device's side wall cannot achieve a satisfactory heat dissipation effect to the surrounding environment.

Recessed cooling units, or side-by-side cooling units that are essentially only visible from the front, use condensers that are suspended from the rear wall of the cooling unit, since in this case the condenser will be hidden by surrounding furniture.

How to arrange the refrigerating equipment with the condenser on the side wall side by side or close to the wall without unduly affecting the heat dissipation, for this problem, there is still no satisfactory solution so far.

Contents of the invention

In view of this, the object of the present invention is to provide a spacer and an improved cooling device, in particular with improved lateral heat dissipation.

The solution of the invention to achieve the above objects is a spacer and a refrigeration device having the features stated in the independent claims. The dependent claims relate to further advantageous technical solutions.

One aspect of the invention relates to a spacer for conducting air along a side wall of a housing of at least one refrigeration device, such a spacer having at least one air guide, in particular is an air guide plate or air channel for directing air flow along said side wall. The air guiding plate is for example mounted against the side wall and extends perpendicular to the side wall. It can also be at a distance from the side wall so that air can pass between the side wall and the air guide plate. The air guide makes it possible to achieve a particularly uniform air distribution on the side wall of the refrigeration appliance which is provided with the condenser. This improves the heat exchange between the air and the condenser. In addition, the air guides can selectively direct the air flow to areas of the side walls that are particularly heated due to the condenser, in order to enhance the heat dissipation in these areas. The air guide is for example oriented obliquely upwards. This allows the heated air to rise at an angle away from the vertical and flow obliquely upwards, thereby ideally directing it to the area on the side wall where the condenser is located. If the air guide is arranged, for example, at the air inlet, the air can be diffused as soon as it enters the partition, so that the air can be evenly directed to the side wall area behind the partition where the condenser is located.

According to one specific embodiment, the spacer has at least one air inlet and/or an air outlet. If the spacer is itself a self-contained, independent part, in this way the position at which air enters and exits the spacer can be clearly defined. For example, if the air inlet is located below and farther from the air outlet when the cooling unit is installed and ready to use, the chimney effect of hot air passing through the partition from bottom to top can be exploited. The air inlet or the air outlet is implemented in the shape of a vertically extending slit, which can produce a good ventilation effect and block foreign matter, thereby preventing the air flow inside the spacer from being affected.

According to another embodiment, the spacer has at least one fan. A fan can facilitate air flow within the spacer. To this end, the fan is arranged, for example, at the air inlet or the air outlet. If arranged at the air inlet, the fan is preferably designed to send outside air into the partition and blow it towards the refrigeration unit. If arranged at the air outlet, the fan is preferably designed to draw the air in the gap between the spacer and the cooling device outward. The fan is designed, for example, as a radial fan, which contributes to a compact and quiet operation of the device.

Another aspect of the present invention relates to a refrigerating device having a housing and a spacer protrudingly arranged on a side wall of the housing for conducting air conduction along the side wall. lead.

The refrigerating device has, for example, a storage compartment for accommodating refrigerated goods, which is divided by a front wall of the housing, side walls adjacent to the front wall, and a rear wall arranged opposite the front wall. Surrounding, wherein, the front wall is provided with a box door to facilitate access to refrigerated goods. The cabinet door is designed, for example, as a hinged door or as a sliding door. The rear wall is for example oriented parallel to the front wall. The rear wall can also be inclined towards the front wall, or run curved.

Furthermore, a refrigerant circuit for cooling the storage compartment can be provided, which refrigerant circuit has at least one condenser for liquefied refrigerant, which is arranged on at least one of the side walls. The condenser generates heat during operation of liquefied refrigerant. This heat is released to the air in contact with the side wall provided with the condenser. Particularly good heat dissipation is achieved if the air flows along the side walls.

The spacer can prevent the side wall provided with the condenser from adhering to the wall or other equipment. For this purpose, the spacer can be connected, for example, to a housing of a second refrigeration device. Sticking to a wall or a second cooling unit can block heat dissipation and lead to heat build-up, which can be avoided with the solutions above. The spacer can also prevent objects being placed next to the side wall provided with the condenser, such as certain plates that will affect the heat exchange between the side wall provided with the condenser and the surrounding environment. For this purpose, the spacer extends, for example, as a lateral extension of the front wall of the refrigeration appliance in the plane of the front wall. In the case of a side-by-side arrangement of two refrigerating appliances, a continuous frontal structure formed by the front wall and the spacer can be formed in this way. This also reduces the chance of dirt getting between the two cooling units. The spacer also has an air guiding function, which can promote the air flow along the side wall provided with the condenser, for example, the spacer has air guiding plates, and these air guiding plates can make the air Evenly flow to the side wall where the condenser is located.

The refrigerant circuit of the refrigeration equipment comprises, for example, a compressor for compressing the refrigerant vapor, the condenser connected after the compressor for condensing the refrigerant vapor, and an evaporator connected to the Behind the condenser and in front of the compressor, it is used to vaporize the liquefied refrigerant. In this case, the compressor and the evaporator are each preferably equipped with a heat exchanger for heat transfer between the feed air and the associated fluid.

Refrigeration equipment mainly refers to household refrigeration equipment, that is, a kind of refrigeration equipment used in the field of housekeeping or catering, mainly used to store food and/or beverages at a certain temperature, such as refrigerators, freezers, combined refrigeration equipment, top-loading freezers or Wine cooler.

According to one embodiment, the spacer surrounds the side wall provided with the condenser in such a manner as to adjoin the front wall and/or the rear wall. The spacer can here be embodied as a direct extension of the front and/or rear wall, so that a continuous area is formed comprising the front and/or rear wall and the spacer. In this way, the front and/or rear wall and the spacers will form a continuous, easy-to-clean front structure. If the spacer adjoins both the front wall and the rear wall, this amounts to assigning the spacer to a certain area of the side wall where the condenser is located, in which case this area can be maximized.

According to another embodiment, the spacer is clamped and fixed on the refrigeration equipment, especially the spacer is clamped and fixed on the refrigeration equipment by means of clips. In this way, the spacer can be fixed on the refrigerating device or removed from the refrigerating device according to specific needs, and the operation is very convenient. For example, spacers of different widths may be provided according to the specific lateral distance required to be separated between adjacent refrigeration devices.

According to the invention, it is possible, for example, to arrange the housings of two refrigerating appliances against said spacer. The spacer can also be arranged between a refrigeration appliance and a piece of furniture (for example a cabinet) or a wall. The spacers are, for example, clamped, clamped or screwed between the refrigeration devices. The spacer is for example tightly closed with the housing. This avoids the inflow of air between the spacer and the side wall. This enables the fluid-technologically precise dimensioning of the system of spacer and refrigeration unit. Wherein, the refrigeration devices are, for example, 10 mm to 50 mm apart from each other. This distance is sufficient to allow effective ventilation and heat dissipation for the side wall provided with the condenser.

Among the features described above or below with the aid of the examples, certain combinations of features which are not explicitly indicated here also include other possible embodiments of the invention. Improvements or supplements proposed by those skilled in the art in the form of independent aspects of the basic form of the refrigeration equipment also belong to other feasible implementation solutions of the present invention.
