Abstract
The invention relates to a telecommunication machine cabinet with refrigerating agent for circular heat exchange. The cabinet comprises a cabinet body and heat exchangers, wherein the heat exchangers are arranged in and out of the cabinet body, and each of the heat exchangers consists of two independent structures, namely an outer structure and an inner structure; the outer structure is arranged on the outer side of the cabinet body and the inner structure is arranged close to the inner wall of the cabinet body; and the refrigerating agent in the outer and inner structures completes circulation through a refrigerating agent uplink pipe and a refrigerating agent downlink pipe or a refrigerating agent communication pipeline. The cooling method comprises the following steps that: the refrigerating agent in the outer structure of the heat exchanger and the air outside the cabinet body exchange heat for condensation; the condensed refrigerating agent flows into the inner structure, absorbs the heat in the cabinet body and then is evaporated to cool the cabinet body; and the evaporated refrigerating agent flows upwards into the outer structure for the next circulation. The cabinet of the invention has the advantages of saving an inner circular fan, saving the cost, reducing the energy consumption of the whole cooling device, greatly improving the energy efficiency ratio, along with rational and simple structural design.
Description
Technical field
The present invention relates to the field of heat exchangers of electronic equipment cabinet, especially a kind of telecommunications rack and cooling means thereof with the refrigerant cycle heat exchange.
Background technology
Each class of electronic devices all is installed within a casing or the cupboard, this installation electronic equipment casing or cupboard are referred to as " electronic equipment cabinet ", in telecommunications industry, be called " telecommunications rack ", " network cabinet " etc., be referred to as " electronic equipment cabinet " here.Can generate heat during electronic device works in the rack, compare comparatively dense as electronic device in the rack, its caloric value will be higher, and at this moment the heat-transfer capability of " electronic equipment cabinet " cabinet is difficult to satisfy radiating requirements, and the most of heat transferred that internal electronic equipment can't be sent is in the cabinet extraneous air.Therefore, need be this rack configuration cooling device.
At present, diversified cooling device is arranged on the market, air conditioner promptly is wherein a kind of.The mode of air conditioner refrigeration, power consumption is big in use, cost is high, and the resistance to elevated temperatures of electronic equipment is become better and better on the market, can bear more than 50 ℃ even 60 ℃ or higher temperature, therefore, air conditioner refrigeration just can not satisfy the market instructions for use or be not suitable for having used air conditioner refrigeration.In order to replace traditional refrigeration modes, the mode that has occurred a series of use heat exchange on the recent market with the heat transferred of rack inside in extraneous air, thereby realize the cooling of rack, and, its structure is that heat exchange products and rack is integrated as a whole mostly, become " electronic equipment cabinet of band temperature control equipment ", in use, the user only need be installed to the electronic equipment of oneself the rack the inside and get final product.
According to the installation method of heat exchanger, the version of these racks has following mode:
A: with heat exchanger be installed on rack the door on structure, as shown in Figure 1:
B: heat exchanger is placed on the structure at the top of rack, as shown in Figure 2:
C: heat exchanger is embedded into structure within the top board, as shown in Figure 3:
Also has some other mounting means in addition, for example: embed heat exchanger within the side plate or be installed on the side plate etc.In the present inside of base station temperature control mode, no matter adopt which kind of scheme, all can be just like a kind of or several shortcomings simultaneously down:
